i soaked the carb in the parts cleaner at work, took it apart and cleaned all the jets and cleaned and tank out and used fresh gas. It sounds like it wants to start but it just wont.

got it to start again with some starter fluid and it will almost idle with some throttle assistance. But the exhaust pops ALOT and back fires ALOT.... and is still very hard to start and got hot very fast... Could this be electrical? Ive read the timing is automatically adjusted by the cdi or some electrical component. Or maybe a bad coil?? I noticed the spark plug adapter from the coil is cracked but i dont see how that could be doing this???

think i may have found the problem!!! I just put new gas in the tank but when i drained the carb just now the gas coming out was yellowish/ orange!!! the gas tank is comtaminating the gas and maybe causing all of this!!! is there any way i could use a glass jar as a gas tank just to try to start it?

(this guy had the tank coated inside with something and i believe messed the tank up!!!) maybe ill have to buy a new one.

Alright i have solved the problem...This has been like a log for me to post my toughts in more than anything, but thanks for who ever helped out. There is a fuel screw on each carb under the bowl that has to be turned out about 3/4 to 1 full turn for the bike to start and idle good. Here is a good sticky for anyone interested in knowing what it is and what it does and how to set it. It helped me out alot.

Projects like this make an excellent case for a used a/f setup like an lc1 or something similar for ~$150. Would save you a lot of time.

just got it going real good....starts right up and idles perfect!!! revs good too

i ordered a new choke assembly and cleaned the choke tunnel with my pistol cleaner kit, worked very well... and i got a twist conversion kit for the raptor and that did it! Just have to cut the old air filter tubing from the xt and raptor and make some 50/50 trick there and get it to fit. If not some thinner and more flexible tubing may be easier.

ready to go riding!!! any thumpers in FL?

better pics next time

Took my first test drive and it pops alot on decelerating.....the other thing i noticed is there is a huge difference in idle when the choke is on and when i turn the choke off....as in i have to adjust the idle when i turn the choke off or it will die. anyone know which jets this could be?

All the choke does is cut off air and let more fuel into the mix, richening up the mix. Idle is supposed to be higher when you activate the choke. Adjust your idle so that it will idle well once the choke is turned off. The pilot jet is the one for idle.

Are you using an aftermarket exhaust? I can't tell from your pictures... If you are then popping on decel will be more pronounced than if you had a stock exhaust on there. From what i've read, most thumpers will pop on decel - even the perfectly tuned ones. My husky does, my XT does and so does my XR. It's just the way it is... If the performance is good and it's only popping when engine breaking I wouldn't worry about it too much...

I read online that if the pilot jet is lean then i will hear a backfire or popping from the exhaust during decel. So a bigger pilot jet is the answer. But how much bigger? should i go up in incroments of 5 until it sounds better....or get one bigger by 10 the first time?
