Hi, i have a drz110 2004. It has a takegawa 138cc kit, bbr exhaust, and the airbox delete kit. Stock carb and stock head. Bike starts first kick even without the choke, and will run all day. However if you blip the throttle off idle it stumbles/ hicups. Also if cruising at very low throttle and then increase throttle and it hicups.

I bought the bike with these mods so i dont know the jets or anything. I wanted to see if some had some base jets they were running to save me some work.

Thanks :cool:

Try raising the needle (dropping the clip) one notch.

I've read some of the threads conserning 2-stroke big bores, most people need to lean the jetting a bit. An inexpensive test is changeing your needle clip. Raise your clip (lean) and see if throttle response improves. If so, you need to move down to a leaner mainjet. If lowering the needle clip helps throttle response, moving up to a richer main jet will help.

Now this is just a basic indicator, a "plug chop" and proper jetting will help alot.
