FYI, I just finished a Krash 1200 build and after the fact I found out the crank was out of true. I sent is out and it was out of true beyond belief. I had the crank completely rebuilt, welded, and balanced. The crank needed a 1.25lbs of tungsten put in it to balance it. Unreal!!!! Highly recommended!
WOHA ! What the heck... 1.25 pounds of out balance!! I have so many questions... (but won't ask most) Have your run your engine since having the crank balanced? I would assume that even 0.125 pounds would be enough of an imbalance to cause the engine to self destruct. I haven't been able to find much / any information on blalncing twin cylinder 180 engines. I know that with a single, you do a balance factor ... but don't know if with a twin they do a similar thing or not.
I did the build for a customer because he bought it from a dude and basically got screwed. I figured it was a top end build like most of the skis I have done. Pressure check and ready to go. Ohhhh no the thing basically didn’t last five minutes until it was running lean. I have no idea how it got out of true. It was never dropped. So I sent it to crankshaft works and said build it and build it right. Cost was $2016. But man it runs like a top. You need to get the top end work done first. Then send everything to them so they can balance it off the pistons. My theory is these machines appear to be really well made. At least looking at the parts. They just need to balance the damn things. Once in balance that should reduce a lot of issues
Joel, please do continue with these technical videos throughout your builds. Love what you do and the time you put into it. Heal upso you can go crash your Krash! 😜
Thanks ! EDIT: The MAG bearing is a large double row KOYO bearing... I thought they were all made in Japan, but apparently they have factories in Japan, UK, Europe, China and India. They are SKF bearings, I believe made in Sweden. Not sure if these engines have bearings issues, but I have noticed that they don't have any oil holes like most two cycle engines do. Normally the transfer ports will have a dimple, that causes oil to pool, and a hole that leads down to the bearings / seals. The bearings in this engine failed due to water being inside the engine instead of outside of the hull 😂 but I may attempt to drill some oil passages. I am quite nervous about doing that tho, As I'm not sure how strong these cases are.
I would expect them to do better... it is an Australian company !! 😁 They seem to have worked out most of their issues with quality and they are still making skis. Their new engine is a beast !! A 1162cc fuel injected engine, basically the same as the one I have. Yes, I'm lucky my injuries weren't worse. I'm hoping that it's not too bad and that it heals quickly.
Thanks for the comment Steve. If it's not obvious, I don't know much about them. I have been on their site and see that the now make an 1162 fuel injected engine that looks like it is based on this platform. Did they made a few different versions of the 997 ? What gives this away as being a first edition ? It looks like they still have the recessed head and cylinder bolt holes, and same exhaust manifold design.
Maybe the wide bore spacing could also be linked to that case having been a rotary induction case at one point earlier in its design. The longer the crank the more prone to torsional twist…
It seems as tho the case did at some point have accommodations for a water pump drive. The rotary valve also makes sense except that that would mean significant modifications/ design changes to remove the inlet holes and disc housing … but maybe 🤔
@@JoelArseneaultRUclips Mark Erickson said it’s made of snowmobile parts. A mixture of skidoo and Polaris. You are correct about the water pump location in the casting.
@@TheStephenspann27 It is a mix of things for sure... I rebuilt the crank with Sea-doo, Yamaha, Polaris, Honda and Kawasaki parts, haha. Honda CR500 con rods, Yamaha mag bearing, Polaris pto and sea-doo or kawasaki for the center bearings. The cases appear to be Rotax from an aircraft engine as snowmobiles do not have a starter drive... they use a ring gear on the clutch. This case has your typical PWC starter mounting area. I haven't been able to find an exact match.
right on, the weather is cooling down here to about 85 during the day.... i must make time to wrench on my skis, im done seeing them incomplete.... i keep jumping back and forth between where to spend time tho.... i really wanna try and make a wider gen 1 x2, and possibly change the hood to open up the engine bay MUCH more like the gen 2. i picked up a free hull
Haha... cooling down to 85 eh... We've had snow the past two days 😂 Yeah, it's always hard to figure out where to focus your energy and time. A wider X2 eh... The whole ski or just the front end ? If i were going to take on that project, I think I would try to get a hull from another ski and then put the X2 top on it... I guess it depends on what type of ski you are building. I've seen a few attempts where people have started to make the flip top X2, but don't know that I've ever seen one completed. It's a neat idea and would make it a lot easier to work on. Whatever you do I'm sure it will be RAD !
1 min in. No all the manifold holes will need a helicoil or keysert. The head.... Yeah I thought about making a billet one. Intake manifold good..... except that top adapter Jacob made. Clearance for the reeds.... They found out it didn't fit just like the pipe elbow that got notched and welded after casting. I think one of the front exhaust bolts has a piece of broken bolt deep in the bottom. No pry tabs.... You can put some in. I kind of had similar thoughts about this thing when I first got it. It wasn't slow when it ran right. A stock 701 had way more bottom end snap(the one you rode in jasons ski wasn't right) . Mid range power seemed good and then it only topped out at about 50. I was more impressed with how the DASA ran. I'm assuming you will make a giant carbon fiber dry pipe for it that will make it RIP. I bet a big pump like a 155 would work better with it. I hope the Krash is worth it. I was looking at big boring yamaha stuff. I was seeing that people use cr500 and 951 pistons with 701s. Apparently you can get needle bearings that let the 21mm wrist pins work with stock rods that use 20mm pins.
I'm actually rewatching your SuperKrash build videos ... I love it. It was actually shiny back then, haha. I'm sad that it ended up not working awesome for you. Yup... you could totally make a better head 😀 might be time consuming tho. The intake adapter seems fine to me, haha !! I didn't see anything wrong with it. I thought that was probably a clearance issue with the reeds, but the reeds that are in it don't seem like they would have fitment issues without the grinding... I guess I need to actually measure instead of just guessing :) A surprise bolt hiding in one of the exhaust holes, haha... Nice. I guess I can mill in some pry tabs eh... I probably wouldn't have thought of that. Sounds like a good working 701 must be pretty impressive ! I would like to make a carbon pipe that was much less of a compromise... but only time will tell. I think you are right about the big pump. I think that a small pump won't take advantage of the torque this engine makes. This is going to be a really fun project for me, so even IF it kinda sucks (and I don't think it will) it will totally be worth the effort. That's interesting that poeple are using those pistons in the 701... I had wondered if a bearings was available that would work... Seems like the needles would have to be very small, but I guess if they use more of them it could still be as durable. MAN... that would be insane !! That would be an 1820 with a 68mm stroke...
@@JoelArseneaultRUclips I bet you take a way more nuanced approach to this but I'm thinking you copy a skidoo 850 pipe and 160hp 997. But man that pipe looks BIG! I'm curious what you think about the DASA Compared to it. I'm thinking it would have been way more money to get it going.

@@Jacobskibros I think copying an 850 pipe would be a good idea with maybe a few changes. I'd like to keep the RPM down a little and focus on low to mid range power.

@@JoelArseneaultRUclips hmmmm. Wondering if the wider spread is an advantage for strength or stability. And now my brain is working.... Will a bigger bearing cause more drag than a smaller one?
@@chuckb.3324 More spread is pretty much advantageous to the transfer ports only, and in every other way it is a drawback... Except that they could have used larger bearings because of the space. The distance between the pistons means that the balancing of the crank will be much more difficult. A twin has some natural balancing as you have one piston reaching the top as you have one reaching the bottom, so these forces cancel each other out... The issue is that you have a rocking force from the center of the crank as one piston is pulling up and one is pulling down. The longer the crank is, the more leverage there is, and so you have more imbalance. This is why 4 cylinders are so smooth. Even tho they are long, generally, two of the outer pistons reach top at the same time canceling out the rocking force while the two center pistons reach bottom, cancelling out the upward force... They are much easier to balance. A larger bearing will cause slightly more drag under low loads, but as the loads increase, the more surface area becomes advantageous. A small bearing, or fewer bearings, will have less drag under low forces, but as the forces increase, the rate that the resistance ramps up increases more.... I hope that makes sense. Either way you do it is a compromise, but with bigger / more bearings you get the added bonus of more durability / longer life.
Hey mate have you maniged to make this engine good ive seen all your vids on it and am thinking of doing all the same things cr 500 internals and porting
Hey, haven't even been able to get it back together yet. It will get built, I'm pretty annoyed myself that its just sitting on my bench... I've been busy with other projects and work, but also, I ordered parts for another project and, wrist pins for the Krash, from WSM almost two months ago, waited for them for a month before contacting them to see why I hadn't received them... They billed my credit card, cancelled my order and didn't bother to tell me about it. I placed a new order with SBT, and have been waiting for 3 weeks now... I just have terrible luck when it comes to this stuff.
I'm excited for this rebuild. I really like building engines, and this is something a little different, so I like it even more. How did you end up with a Predator with a 701 ? I suppose that's one way of making sure you have a dependable engine ! Yes, my crash could have been a lot worse. As soon as I asked that question I was like ... They sell bare hulls idiot 😂... but now I'm not sure. I thought they started out selling hulls but now just complete skis... I guess you will let me know.
@@JoelArseneaultRUclips i just bought it like that 2nd hand mate, cost me $7500 aussie and has a blowsion pole. yeah the 701 has been good to me and was easy to work on, its a tight fit in that krash hull though!., i think the krash engine will be fast but i dont know much about them. i know they have 3 power modes or something so maybe just lock it into the top one haha?
@@chargerzrsik That's cool ! I would think that the 701 is a bit smaller, so the Krash engine must be really really tight. Lots of people like to talk trash about engines, and with all the hype I can see why people expect so much, but the bottom line is that it is a 1000cc twin.... Unless it's working like a complete piece of garbage, it has to work good. I'm going to have fun with the project, regardless :) Yeah, they have different power settings. I think it just changes the timing curve on this engine as there not much else they can do. Should be interesting.
That depends on what you have or haven't seen. I did do a porting video and a crank rebuild... then I basically ran out of money... and somewhat out of time. I keep hoping to get back into it, but that will require things to change significantly (for the better)
They admit to "looking into" BRP stuff in their KV997 promo video, but then they go on to say that it is "ground up engineered in house" ... like ... no, no it's not, haha. I've seen a website where someone was compiling a list of parts from other sources... 850 skidoo reeds... good to know, haha.
The 21 krash predator I bought worked for 40 minutes and the engine blew in half and water was leaking out the engine, everywhere. Rubbish engines and garbage customer support
Thanks for your comment. This is not the first story I've heard like this, for sure, and garbage customer support makes everything a million times worse. That being said, I worked for Yamaha and Polaris in the 90s - early 00s and we had lots of polaris snowmobile engines that got cut in half or completely destroyed in 30 minutes to an hour of use... Yamaha wasn't quite as bad, but we had plenty of V-max 500, 600 and V-max 4 engines that got destroyed with very little use. Yamaha is known for their quality and durability, yet when you work for them you see lots of horror stories, and every one of those stories has a customer who had their day ruined after spending a butt load of money. It's not hard for me to believe that a small manufacturer building performance two cycle engines would have issues, however, customer support is extremely important and without that a bad day becomes a horrible experience.
I don't know the answer to that, but I'm sure someone on the internet knows. A lot of manufacturers use Yamaha stuff, but I have not idea what pump they use ... and they probably use different pumps on different units ?
@@JoelArseneaultRUclips yep exactly. I like the tuxedo t shirt you have in the first part of the video. It’s interesting to see your thoughts on the krash engine.

They admit to "looking into" BRP stuff in their KV997 promo video, but then they go on to say that it is "ground up engineered in house" ... like ... no, no it's not, haha. I've seen a website where someone was compiling a list of parts from other sources... 850 skidoo reeds... good to know, haha.
The 21 krash predator I bought worked for 40 minutes and the engine blew in half and water was leaking out the engine, everywhere. Rubbish engines and garbage customer support
Thanks for your comment. This is not the first story I've heard like this, for sure, and garbage customer support makes everything a million times worse. That being said, I worked for Yamaha and Polaris in the 90s - early 00s and we had lots of polaris snowmobile engines that got cut in half or completely destroyed in 30 minutes to an hour of use... Yamaha wasn't quite as bad, but we had plenty of V-max 500, 600 and V-max 4 engines that got destroyed with very little use.
Yamaha is known for their quality and durability, yet when you work for them you see lots of horror stories, and every one of those stories has a customer who had their day ruined after spending a butt load of money. It's not hard for me to believe that a small manufacturer building performance two cycle engines would have issues, however, customer support is extremely important and without that a bad day becomes a horrible experience.
@@JoelArseneaultRUclips agreed 👍
Hey, do you know which impeller I can use on Krash? Cuz their oem way too expensive.
I don't know the answer to that, but I'm sure someone on the internet knows. A lot of manufacturers use Yamaha stuff, but I have not idea what pump they use ... and they probably use different pumps on different units ?
@@JoelArseneaultRUclips i been told it's a mag pump so it needs a 5mm cut back so the prop sits closer to the veins. It's a 148 impeller
First 🥇haha
Congratulations, haha. I guess if I post late enough maybe you actually have a free minute... or maybe not.
@@JoelArseneaultRUclips yep exactly. I like the tuxedo t shirt you have in the first part of the video. It’s interesting to see your thoughts on the krash engine. I don’t have too much to say about it because I’m not much of a two stroke smart person. But still a fun video to watch. Milo is attempting to jump on my neck so I gotta go now 😂
@@JetSkiBrothers 😂 Milo attempting to jump on your neck... Sounds an awful lot like having a cat ! Sometimes I forget what I'm wearing until I go to edit a video and then I'm like 😂🤣😂🤣😂🤣 ... I have all sorts of silly shirts and every time I wear one, someone always comments about it. This video would have been two hours long if I started talking about two cycles stuff in depth, so I tried to just touch on the basics and not bore people to death
👍
Great videos on this! Are those bearings made in Japan from krash?
