Default 55hp at 6000ft above sea level

do you have just the 686 big bore kit? Is there any head work done? Did you run slicks or nobbies on thr dyno. do you have the 35mm or the 39mm fcr. what size of jetts are you running in the fcrs at 6000 elevation.

wow 106mph thats geared extremely high, do most 686's put out that much power? or is that a high run?

yea i have port & poilish on the heads i am running the 35mm FCR's with 132 jets, i was running hossier "H" blocks on the rear. most 686's aren't modded as much as mine is the dyno guy says that anywhere above 50hp on there dyno is good. the owner of the shop said that minus the big bore 720ish raptors that it the biggest under 700cc horese number he has seen. my tourqe was 47 which at 106 top speed i think is preety good, yea i know 106mph is fast but i have to try and give the banshees a run for thier money. the first rave of the season is this weekend so i will have top see how i do, i am hoping to be one of if not the fastest 4-strokes. i run in CHCA, colorado hill blimb asoc. picts are in my profile of what type of racing this is.

Your bio page says you're running 39mm FCRs? Did you post that before you made your choice?
