EZ2FLEE Posted November 3, 2011 Report Posted November 3, 2011 Oct 22 went to silver lake, bike ran excellent, right up until the end of the day..... Tossed a ring on right side, so shees torn down and I'm gonna be sending the crank to passion for weld and true...... My question is @ 1300ft can I get away with 16cc domes on 110? ......or due to the fact that I'm running T5s and a Chris merry trail port would some custom cuts be of benefit? If anyone has any input its appreciated.......... The bike is a all around ride trail,dunes,hills...ect......thanks Quote
EZ2FLEE Posted November 3, 2011 Author Report Posted November 3, 2011 Ok the bikes current setup is stock stroke, .040 over pro lites , noss cool head 20cc domes, +4 timing stock carbs, boyeson pros, tors removed.......looking for lots more this winter was thinking 33mm flatslides, 16cc domes, nology coil and wires, +5 timing, crank work, billet intake, dual pingel, switch to a br9 plug.....and run 110.......:..also if I'm mixing 40:1 dominator w/ 93, would I still mix 40:1 with 110?

Why would you switch to a 9 plug? The only reason to run a 9 plug is if you ar running on alky. Bikes running on gasoline, whether it is pump gas or race gas should run an 8 plug. Yes, keep your mix at 40:1. If you are only at 1300 feet, I think the 16cc domes are excessive, they will kill your topend overrev and you will be expierencing detonation. If you truly want more power, you need to get it ported. AND until you get it ported, there is ABSOLUTLY NO NEED for carbs bigger than 28mm. Quote
EZ2FLEE Posted November 3, 2011 Author Report Posted November 3, 2011 K I didn't know wether or not to keep the 8s or not running 110, and if you read the post its says it is ported..... I wasn't sure about the 16s that's why I was asking my baseline was 17s......I think that will be plenty...... Quote

I wasn't sure about the 16s that's why I was asking my baseline was 17s......I think that will be plenty...... Sorry, I was going off what you had in the second post. Either way, 16 or 17cc is to much. On an all around bike you want your compression to be right around 180 psi. Even with the port job, I would stay with a 28mm carb, I would not go with bigger carbs until you start increasing displacement significantly- like a stroker motor and/or a substantially bigger bore. Bigger carbs will give you more high rev power at the expense of low speed torque, thus making it harder to climb hills or start out. But, they are great for a drag bike. Quote
EZ2FLEE Posted November 3, 2011 Author Report Posted November 3, 2011 So I would be better off running a 28mm flat slide or 30mm Quote
EZ2FLEE Posted November 3, 2011 Author Report Posted November 3, 2011 As far as domes go I read that for every 1cc u go down u add 8-10 lbs compression..?... If that's so is there a cut off point between 110 and alky....like there is a cut off between pump and 110 or doesn't it matter? Quote
