okay. so now i have a question... which boot do i need? the one going to my airbox? or the one towards the reed cage... the one going towards the airbox looks like there is no way in hell it will go on... and the one towards the reed cage looks like a tight fit.
you need to get one on the engine side or you can use a dremel and open the stock boot up. i'm running a 36mm mikuni in the stock boot. and then you also need to do something on the airbox side. here's what some guys do on the airbox side

I have the same carb on two of mine but no 240 BB. Pilot, get a 30, 35, 40, 45. I use the stock needle, you'll need to mess with the clip. Main, get a 200, 190, 180. That should get you close.
i was told i needed 150 148 145 main. 50 48 45 pilot... and i just cant find the right jets to order.
can someone help me out?? i cant find the right jets to order.... ppl have told me 150 148 145 main and 50 48 45 pilot and ive heard around 180... id just like to find out what i really do need to order and where i can find the right ones for my carb... i got the cable today.. just waiting on info for the jets
I spent the last two nights dialing in my carb and this is where I am. I'm running 93 pump gas pre mixed, 180 LBS static compression, K and N filter with open air box and outerwears cover, Toomy B1 pipe, duel stage reeds and a ported cylinder. I went from a 45 pilot to a 30. It was starting with no choke when it was cold. The smaller pilot fixed that. I have the air screw out 1 ¾ turns. When I whacked the throttle open, it would fire.......then hesitate............then wind out. I dropped the clip on the needle to the second from the bottom to make it richer. The result was instant throttle response with no hesitation. I have a 200 main in it. Just because this worked for me doesn't mean it will work for you but it will get you close. Again, I'm running a 34 mm flat slide from a 250R. The temp outside was 60 degrees when I did my jetting. These jets are probably too lean for low temps and riding in the winter. A good test is to start the quad and let it warm up. Let the engine idle and whack the throttle to wide open and release. The engine should bark with no hesitation or bog. You have to really whack the throttle open and close fast for this to work. Rich jetting will smoke and be slow to respond, lean will skip and miss. It's going to be like 70 degrees here in CT for the next couple of days and I'll be testing these specs quite a bit. I'll let you now later tonight how they work on the trails.
