I just slapped a kitaco ultra head on my 88cc big bore from classic honda. It runs great from mid to top but the bottom end bogs bad. Sounds like bur bur bur bur, kind of like a rev limiter. If any one has any tips or has put an ultra head on their bike, let me know, thanks.

Re: ultra head

What size carb are you running? whats your gearing?

I am running the 20mm carb that comes with the kitaco 88cc kit. My gearing is 15 37, i know that is not the problem. Its some where in my jetting. Just havent figured out where just yet.

you may just need to adjust your carb for that head, by the way did you just get a head alone? and how much did you pay for it?

I already had the kitaco 88cc big bore kit. What I just bought was the Kitaco Ultra Bore Up Kit. Whick is a ultra head with a full race cam, large valves, springs everything you need in the head and a high compression piston. I cant say the price i payed for it cause i am a dealer with classic honda, but it retails for $800. www.hondaminitrail.com

Thanks for all the tips guys. I am currently still jetting on the bike. I just put the 18mm carb on it and it helped out some but still has that bottom end bur bur bur. And I talked to shane a classic honda today and he said that the race cam was one of my problems. I wish he would have told me this before cause I told him I was wanting some bottom end power for MX, but oh well.



Skindonor- yeah that 117 does roll. Classic honda had sent one of their riders (Bean) to a race at an indoor bmx track in Houston, TX. The bike was too fast for the track. I dont want something that fast, I just want a little more than the regular 88.



motoguru- how does your bike run now that you have the touring cam?



oldschool- how does yours run as well?
