Ok men. Today imma gonna explain what I had to do to put a larger carb on my new CRF110.
(FYI this is the carb that comes with the TB 88cc kit. 22mm... I think. Stock 110 is 13mm.
I wanted to use the stock cable if I could (I know, I'll need a longer one anyway when I mount up my zocchi's) lightly held cable in vise and cut off the crimped end.
Once that is off, and Hopfully you didn't hog up the rubber/plastic sleave in the elbow. Ill reuse this in the larger carb cap.
Carefully pull the sleeve out of the stock elbow. If you pull too hard, and a small burr catches it, it will ball up and it will stay like that.
I got a different 20mm intake, but I noticed the stock intake looked bigger then expected... So I measured it, and its all but 20mm... So I decided to just use the stock intake.
I did not use the stock choke set up. But the fuel line and vent tube are all correct length for this carb!
Bolted it all up and gave it a try.
1st attempt the carb was way lean. Long story short, needle is in the 2nd to richest position and I had to go up 2 sizes on both ends of the jetting.
Here you can see how small the stocker is in my hand compared to the TB carb.
results....
Motor is much stronger! Tickled pink!!! The exhaust tone is also noticeably different. Not louder, just a change in tone. If the bike came with this carb.... I swear it would make the cover of Time magazine... Or be featured on USA Today show!
Im calling it now. Carb upgrade will be best bang for buck! (Tho I hope I'm wrong;-) )
