- I finally take the engine out of the bike and strip it right down to discover the root cause of the rattle. Turns out it was a very worn primary chain. Now I need to figure out what parts I'll try to install from the XJ750.
Even though I'm not doing everything you did... These videos are still indispensable to me getting my new 82 xj650 running. Having never wrenched on a bike before, you're getting me through the hard parts better than any written manual
Thanks Mike, glad my video's have helped you out
Nice job mate can't Waite to see the final results
Coming along nicely, really makes you wonder why the chain is so loose, awesome video, 👌🏼
Yep, not sure yet. Will take a close look shortly. Seems odd given it only drives the alternator and drive to the starter motor...
@@Mezzmoengineering You are right, this chain drives only alternator and starter. In my engine chain slider was broken and i have replaced it (the chain too). Check the oil nozzle (it lubricates primary chain) because loose chain could damage it.
@@jacek5788 Thanks, yep the oil nozzle is damaged. I'll have to replace it,,
Always good to watch your videos but this one scares the hell out of me with all those parts. This is not for the faint hearted :)
Keep making these videos please.
Great demonstration and narration.
Thanks, will do!
My engine was something around 50kg.....I tipped it sideways onto tyres....then dismantled the engine ....every bolt....going to rebuild...new bearings...bolts etc....my barrel was a nightmare to separate....it’s a 97
Do you need to remove the head and jugs to split the case.
I recently replaced the cylinder head gasket and base gasket at the jugs.
Dont want to have to replace those parts again.
Cost on gaskets.
Can I replace the chain on my bike without pulling head and jugs again?
Hi Mate, If you just want to get to the oil pump and transmission area only then the bottom case with come off with the top end all together.
pickup coil allen bolt @10:54 is left hand thread ? this week i buy xj750 to make cafe racer so hope you can help me if i got some question
Hi mate, no at 10:54, its NOT a left hand thread. ITs a normal thread. See ask questions, just email me
@@Mezzmoengineering thank for help
I got to do this to fix my starter clutch bearings but I really don't want to
It does look like a big job. I'll take a close look at the starter clutch soon to see whats involved
Hi there. Nice series you have here, and I stumbled into. I wonder, why aren't you just going to try to use the 750 engine? Boring a 650 to what, 690? 700? why not just use the 750 now that you know this one has some issues? And why YICS? I am working with a 550 vision and its one of the first things they recommend you remove, as how much it helps is debatable, and often another thing to leak and cause run issues. VS what YICS does is supposedly spread the gas atoms out for more thorough combustion. Not sure if that really gives more HP, though it might make the exhaust a bit cooler considering there will be less burning gas in the exhaust. Though the YICS system looks completely different on how it is set up on the 4 cyl. Best of luck!
Hi Chris, welcome to the channel. Yes, I could just fit a 750, but that would be too easy, LOL. I have a complete 750 and my plan is to convert to YICS mainly because I think it looks better and it does appear to provide better economy. I'm going to keep the 650 casing etc, but install the 750 crank and bore out to 68mm or 820cc as well as use the 750 cams. I'm also going to lightly port the inlet and exhaust ports and then tune the carbs using different jets. To make YICS work I need to use the 750 barrels and head. Some 650's had YICS, I believe they developed that due to people complaining about fuel consumption on the first models.

650 Seca Turbo's have YICS
Love what you did with this bike Mezz. When you first fired it up, even I had a virtual chub.
Did you have to taer down the top end to split the cases?
No, you can split the cases without touching the top end. BUT, you won't be able to remove the pistons or crank unless the top is removed. You can't get the primary chain out either without the head removed.
These videos are awesome!
Thanks James, glad you're enjoying them
how did you get the airbox assembly out of the frame with the starter and alt still installed on the engine?
Hi mate, check out part 18, its all there
Gee 110k an still looks pretty good inside, was there anything else that puts tension on that chain and might have let go over the years? You will make a awesome motor with all those parts an skills 😁👍
Thanks mate. Yep , does look pretty good except for the primary chain. Still need to look at this more to figure out what caused the issue
Good day... you have a parts out of xj 650 because i have a xj 650 motorcycle but the engine blown out the crankcase has a crack i need some parts to buy.?
Hi Romeo, Yes I have some parts. Get my email from the About section and contact me on email with what you need.
your bolt organization gives me anxiety. Id never be able to figure out hwich one went where
LOL, people that know me say the same. Doesn't bother me as I seem to figure it out later
👍👍👍
XJ600 engine was around 50kg
need a supplier for yamaha parts., do you have a website ?
Hi Joe, no specific website, just a lot of searching. EBay was a good source for me as well as my local Yamaha dealer
i have xj600 do you guys think it worth to fix it ?
If you like the bike then you should fix it up.
my XS110 has a similar rattle...Thanks, I guess.
Its a hassle but at least you know what the problem might be....
Al you have to do is use is rat it's us at least 3if you can and figure out how to balance themselves on front midol and back you can get them under the motor undow the 4bolts to the drive shaft and slowly on each won _____wons it's up a little put 1/2 inc boards under it wat your doing is easying it out and on to a small Cart you don't need 2 people thanks
