Bugaboo, can you email me williamsmotowerx@gmail.com

I sent you a PM bugaboo with my contact info

Stoich is just relationship of optimal fuel burn given the amount of air. It doesn't take into account what's really happening in a running engine being 4 or 2 stroke. Leaner is almost always meaner. You just need fuel that's tolerable. A little rich ... more »

YZ's are borderline safe with stock jetting and pump gas. Straight C12 (32:1 oil), don't dilute with pump gas... jet down 2 sizes on main and you will make more power. Silencer is not killing top end. A head mod helps quite a bit, stock head modified. ... more »

My favorite track

Lol at all these replies. Someone did that on purpose (not very well) as a performance mod. Have someone remove it that knows what they're doing. You don't need new cases

That's how timing looks on Kaw 450's. A lot of people time them wrong, yours is correct.

Just jump it to your car. No need to buy battery. Make sure polarity is right

Sounds like capacitor. You can unplug green connector by left radiator. Wire in a 12v dc battery to side of plug that stays on frame. If it starts easy, your capacitor is bad. If still a problem, borrow a friends ecu. I had a stock one go bad on a 18 ... more »

Spray it with wd40... it fits. Just not easily sometimes

I was kind if hoping this was going to be more of a fun format. Getting ex pros and anyone else that wanted to race a 125. Like the Dream race. Todd Dehoop had shown interest in racing one of his mid 80's factory bikes he owns, but wouldn't be able to ... more »

You can jumper wire starter directly on bench. Suggestion above is also very valid, assembled, cam chain tensioner out, rock cams back and forth. If they're tight, cam caps need to be sanded. No explanation for why they get tight other than heat, cold ... more »

You're doing it correct. But you need to crank engine with spark plug out to build oil pressure.

Youtube tv has ufc on, wtf

I can get regular YT on Amazon no problem through a browser, FYI. Google was no help with a YT tv Amazon workaround, unless someone is more clever with searching...
