you got a air leak somewhere dude

I agree with the plug caps. I the the EXACT same issue. New plug caps. Ran like a champ. Buy brand new caps from Yamaha

The way to really tell for MAXIMUM power, so to run on a dyno, and put a exhaust bung in that reads Air/fuel ratio. Keep leaning it out until the power starts to drop off. Then you know your perfect. USually peak power is around 13:1-14.5:1 Depending on the engine. Every engine is alittle bit different. I will agree "Peak" power on a spark plug soot ring will be less then a dimes thickness. But if you go with a dime thickness its safe and its close to perfect.

The ideal Soot ring thickness for WOT jetting is the thickness of a dime. "Light light bown as thick as a dime" is darn close to perfect.

your waaay fat. I would drop 3-4 mains

Thats with bone stock nova. Firestone tires and exhaust manifolds. Stock cam. Stock carb ect

gay?....

This aint no Banshee. But this is what i do for another hobbie. Drag racing Muscle cars. Enjoy!!

HOpe you guys enjoy. This is me drag racing a Small BLock LT-1 Nova

FIrst of all what kind of fuel are you running? U deffinitly need to check fora vacume leak as the plugs are very different from left to right. But keep in mind if you are running pump fuel with 10% ethanol they will burn clean like that and look new if its burning a tick lean. if you are looking for 100% performance. you want to have the plugs looking more cleaner then black

leave the mains. Change the pilot and your needle setting

Vito's had issues with their 10mm cranks. They are junk, and i dont think they sell them anymore. NOw vito's 4mm crank is bullet proof. I run one and have zero problems.

If you run good fuel. Crank it to +7

More then likely you need a carb cleaning.

i run it in everything. Chainsaw's, my sv650, my CFR450R, my F7, The race car. Its too bad they are trying to get in banned because it has lead in it. Because airplanes make so much polution in the world.... COUGH COUGH.. Maybe .0000075% ofthe worlds air pollution. Stupid governments and tree huggers...
