Jetting the 2021 Beta 200rr with incredible improvement!!

- Wow, some basic minor jetting adjustments really woke up this bike! Remember I'm running Avgas which makes it run a slight bit richer usually one size, so going one size leaner just to start. I still need to do some fine tuning, but this really made a huge difference. Don't be afraid to move 2 jet sizes either way to see how it acts as you learn the art.
Just tried these settings UK sea level 6C bike ran well to lean rattling . I had to go back and bin the test run as it began to overheat ! Im running an RKTek insert so think mine prefers a tad richer. Still I had to give it a go
Yes run richer with the RK Tek head and make sure your running the octane the head is designed for and it should do well.
So riddle me this on the oil injection for the 200. If you lean out the bike with jetting, aren't you then over oiling because the oil is sent via a TPS. For instance at idle it's meetering the same amount of oil regardless how much fuel you are feeding it through the pilot? I've been struggling with smoking and installed the JD Jet kit and didn't have much effect on the amount of smoke with a 38 pilot in it. Dealer changed the pump and tested new one and said it is getting correct amount of oil with the flow test at various throttle positions. I'll be deleting the oil injection next to solve this problem. Some folks have mentioned that it doesn't happen when they have a track at their house because you aren't shaking oil out of the line bouncing the bike around in transit which supposedly causes pooling that has to be burned off when you cold start the bike. I guess more oil is better than not enough, but I'll take my chances the pre-mix for while and then jet for performance.
Ok a lot to go over here. So first, yes the same amount of oil no matter what jetting is. It's at about 100:1 at idle so no not over oiling. Smoking at cold start is because the engine isn't up to temp to complete the burn as well.as extra oil in the crankcase from the gas evaporating. As far as your bike smoking, it could be the oil you're using. You need different oil for trail then wide open MX. For instance, Maxima 927 in the trail would make a mess, Maxima Super M would be better. Amsoil Dominator in the trail would make a mess, Amsoil Interceptor (what I use) would be perfect. Also your smoking could be from a right crank seal leaking as Beta has had some issues. I'll be doing a fine tuning video with the jetting to show what to look for.
@@TepcoCycleRepair well I’m using the motul injection oil that came with bike. Maybe another would be better. Not loosing anything measurable from crank case. Oil runs down pipe while riding, so worse while cold but still not right
@@StoneyWV There are a couple different levels of Motul some for trails some for race I dumped mine and used the Amsoil interceptor. Some people were complaining the Motul wasn't burning completely.and leaving a mess. I really like the oil injector and don't plan on removing it, If I were you I would just try a different oil and see if that helps.
@@TepcoCycleRepair thanks a bunch; I’ll try the new oil first
As a new 200 2022RR buyer i was glued to your vids on the bike then you baled .....such good advice but disappointed the way you handled dumping it . Woods rider since 72.
I understand, I really liked it, but I wish it had more torque. I was getting stuck on several short run up climbs. If I rode different terrain I would have kept it. It's a great bike, probably the most nimble bike I've owned, you'll love it.
Nice video, I’m picking up a new bike this spring and I was almost certain it would be a KTM 150 xc w TPi. I am thinking about the beta now too but it’s a tough choice lol
Both are great bikes, if you are coming up from a smaller cc bike the 150 would be good. If you're coming off a larger cc bike the 200 will have more low end torque. I will say if you're looking for more parts and easier availability it will be the KTM.
@@TepcoCycleRepair Im coming off of an 04 CRF150F so either way I think its gonna be a huge increase of power 🤣 , I think the 2 stroke 150 will be plenty of power for me though, I rode a buddy of mines old 250 exc and it felt like it had way more power than id need. the ktm dealer is also a lot closer to me so in the end ill probably stick with that. I saw your vid about the shifter on the beta so thats got me thinking twice lol
Nice video. I have the same bike as you with similar issues as others in the comments section. Lowered the needle which seemed to help, then went to a 42 pilot jet which did not help. Bike bogged with any throttle and barely ran on idle. Went back to stock pilot and it runs fine but still fouling fairly often. Gonna check/adjust float height next. Probably try the jet combo you suggested because it looks and sounds like you have it dialed in. Did you make any air or fuel screw adjustments? Have you changed any sprockets? I am finding 13 and 52 are working well for single track woods riding.
Yes I turned the air screw just until the rpm stopped rising. I think I'm at 1.75 turns. I will be dropping a front sprocket size to a 14 to start. Make sure your float height is correct, and make sure you're using a trail oil.
Thank you ..
awesome video!
Great vid and I'm making changes now. As I started fouling plugs and it is spoogy so going to lean it up. What are u summer conditions? My elev is same.
I'm in NC hot and stupid humid! Not sure what oil you are using and how you ride but if you trail ride, slower stuff, use either Amsoil Interceptor or motul 710. If you're fast and on the pipe a lot, try Amsoil Dominator or motul 800. Sometimes the only thing you need is the right oil for your style of riding. Oh and if you removed the OI, Amsoil Saber is awesome stuff, used it for years in my other non oil injected bikes, it's pre mix only.
Excellent VID...Have 2020 200 RR and was considering doing the same since IMO the bike was running rich from factory. Curious what brand replacement jets did you use, and does it matter?
I used Keihin jets. I think the 38 pilot is still rich. I'm going to try a 35. I'm really close..I love jetting and strive for perfection..lol..
@@TepcoCycleRepair I think I'll first drop the needle a position or two first, before swapping out jets
Hi, your float seems good at 6.77, why does Beta manual state factory set float height at something like 16?? , do all Beta 2T bikes come set too high?
Great info on tuning!
It is a mistake in the manual. Looks like they were going to use a different carb so that is the setting for a carb they didn't use.
@@TepcoCycleRepair Hi, that explains it then , thanks, seems a lot of owners here in the UK have to lower the float and drop the needle a notch right off the bat to get better fuel mileage, crisper response etc.
Nice video ! How did you adjust the PW btw ?
I set the Power Valve flush with the PV cover.
Amazing job, so it u changed them for a 40 and a 58?
Yes a 40/158 #2 on the needle but first make sure your float height is correct. After some more fine tuning in my area I'm now down to a 38 pilot.
Awesome video. Would this be the same for a 250. I have foulde 2 plugs and the bike is in the shop for repairs and it blows a lot of smoke. I sm not sure how a carburetor works. I always have had 4t. I have worked out how to warm up the bike. But iam not confident that it will be running ok when I get it back.
First try a different oil that's better for your type of riding. Then I have found most are coming rich from the factory. You should never be fouling plugs. Turn off the choke as soon as possible. I'm not sure what stock jetting is on the 250 to be able to give you any size suggestions. Hopefully your shop will adjust it properly.
Cheers mate
Hey Tepco, i have a 22' 200re with 62hrs on it. i bought it with 52hrs. i have fouled the plug once and swapped it and it worked fine for the next 5 hours. recently it was making a slight knock at low gear high rpm and would go away at high speed. so i did what i know which is not much. cleaned air filter and oil change. started right up but it would bog pretty bad when i would try to throttle up in neutral. i was able to ride it but in idle it bogs and if im riding it revs high and ticks. i checked spark plug and it was blackish brown and a bit wet on tip. thought about swapping and trying it again but i havent. i run premix 50:1 liqui moly ethanol free. sorry for long comment, i just need some help lol im a rookie to this 2 stroke stuff
A lot depends on altitude temp and a few other things. But if it's bogging off idle I would try just one size up on your pilot jet to start with. While you're in there write down, clip position, main and pilot jet sizes.
I am in Austin tx and it’s boiling hot here. I will check that out and report back
What is your needle marking there?

Hey just got my brand new 2021 beta 250rr non race so oil injected. Running very rich but literally dont have 1 hour on it eveb yet. The dealer said they purposly added some pre mix in the gas for break in process. Gas is alost done thankfully. Intending on running sunoco 110 leaded no ethanol in it. They did not even give me any extra jets or needles with the purchase of bike. My game plan is fill it up with the sunoco taks it out to the woods , immidiatly order jetts. And then when they arrive bike should have at leaast a few hours on it by then. Any other sugvestions to do in mean time like raise idle, or air screw ?
If you're going to run 110 and want to get the most out of the engine, get a head to match the octane Frome somewhere like RK tec. Or if you want to keep the stock head, I would just run non ethanol pump 94. As far as your mixture screw, it would depend on temps, altitude. Just slowly turn it in and out for the highest idle. If it's not changing when you're turning it. You need a different size pilot.
@@TepcoCycleRepair if i run the 110 with the stock head will it messs up the bike ? And really i thank you for your time. And if not will with to non ethanol 95 after i use this 5 gallons i paid for. Lol 😆
@@jcsquared1111 No it won't mess anything up. The higher octane will just burn a little later so you won't get 100% out of the engine. But the real question is, would you even notice?? Probably not. It's always better to run higher octane than you need then lower octane then required.
@@TepcoCycleRepair you are the man. This isy mid life crisis. 40 years of age stopped riding well pver 20 years ago and just out of nowhere missed it dearly. So now it is a matter of getting my riding skills back up to snuff as im insanely rusty and slow. Also have 0 people to ride with as long island new york is pretty poor for riding. But come fall im packing up moving to Florida most likelly Brooksville area and with all the incredible riding places down there i hope to find some riding buddies to link with. Pleasure to meet you and really enjoy you vids very helpful and informative.
@@jcsquared1111 Growing up and finding places to ride on LI,..I feel your pain!
Can you just rotate the carb to change the main and pilot?
Yes
Would you also be able to get to needle doing the same thing?
What is your elevation and temperature?
700' it was around 35-40° when I made this video and it's still a bit rich on the pilot. I think I'll end up with a 38P.
Hey bro I got a 23 200rr and its pretty cold here in Texas and I wanna ride, do I need to rejet my carb? Nothing in my manual says anything about temp... what should I do
There is a jetting chart that has elevation and temp, it's in the electronic owners manual. The bike is jetted rich from the factory so you should be fine as it is. I mean, how cold could it get in Texas?😁
Yea I found the jetting chart in the manual, however for some the place I bought the bike from installed a jd jetting kit in it and all I know right now is that its got a 175 main.... there's a 45 pilot jet in the box, but the package gives a list of jets.. so from what I'm seeing the pilot jet from jd is 38 and 175 that don't seem right to me..
@@freetaylor72 The 45 is the stock pilot size it was way to rich. I ended up with a 38 pilot, so I think you're good.
@@TepcoCycleRepair
Yea thats whats in it with a 750 main. I road yesterday and the bike was idling high and sounded ... "tingy", I was gonna try raising the needle one clip and look at my spark plug. I know for a fact that the bike was running very rich cause its spitting oil out of the exhaust coupler and the silencer...didn't get any spooge yesterday but I didn't really ride hard. Did notice the higher idle and the sound of the motor...this is whare I get into sketchy ground. Throw a lectron on it if could afford it lol
@@freetaylor72 You could try a 40 pilot or try adjusting your mixture screw until you get your highest idle the count the turns from lightly seated. You need to end up between 1-3 turns out, if you're not change your pilot jet. Depending on the riding your doing, oil out of the pipe may just be the oil your using, but it's definitely something you should fix. Contrary to popular belief you shouldn't get any coming out of your junction or pipe. I run Amsoil interceptor in the injector tank for trails. Maxima Super M if I'm pre mixing.
Float height is from 6 to 7.5 ok?
Yes, I would shoot for 7mm.
@@TepcoCycleRepair I set it to 7.2mm today and it's better. Gasoline was leaking on the steep hills.
What is your elevation?
I'm at Sea level.
