Hi, i've had my 80cc(66cc) china engine kit for quite some time, and without upgrading anything, i feel as if my motor can do more just from hearing the revs. I go about 70% throttle, and it runs fine, but when i give it WOT it barely nudges and has a loud ugly bogging noise..just doesn't sound like a proper running 2 stroker.
So im thinking besides an expansion chamber to help me out(which im hoping i'll get soon) im thinking a larger carb jet would help me out with this bogging issue. I've recently looked at a post (http://motorbicycling.com/f30/chinese-bicycle-motor-jet-size-1662.html) Where someone had a similiar issue, and somebody posted about the stock jet not being big enough. Luckily for me he mentioned a dellorto jet being a great replacement from a place nearby from me (MAIN JETS FOR SHA & PHBG - SIZE 50 TO 130 - ( 51,111,113,117,123,124,129 - NOT AVAIL) - CODE 1486) that i can get my hands on.
So my questions are : will this really work? Is it a good idea? And if so, how big of a jet would be ideal? Any criticism/opinions are greatly appreciated, as i love my build and would like to see it improve as i plan to do a road trip on it this summer.
