It's a simple fact that the correct jetting gives you the most power so hence the jetting which gives you the highest top speed is the correct jetting. From there you work your way down, and experiment with needle height and then finally mixture screw. I don't know why it keeps getting posted over and over again if you're lean on the top end just turn the mixture screw. That's absolutely 100% bad advice as it doesn't solve your problem and only makes you foul spark plugs and again on a plug chop hides the true reading. |

That said, I run a 95in a 83cc BBK, and I probably could get away with a 88 to 90 mainjet. My current 95 and tape-restricted air-filter proves that the 95 is too big. I am going to suggest you adjust the needle to a richer position.

I'll order me up a #95 from Absolutely Scooters and see how it works. Thanks again! Quote:
If I'm getting no popping, backfiring, or vrapping and I'm almost hitting 60mph downhill, should I really mess with the needle? My plug chops were only WOT and I thought the needle stops effecting throttle at 3/4? Am I incorrect? My full range of throttle is the best it has ever been right now.
