ok im just gonna put the 180 back in it till i see some posts on this hopefully its just starving for air still justoutta curiosity is a 38mm airstryker with reeds and pipe able to breath sufficiently with just the top off air box?

 

A 38mm carb is too large for a stock cylinder. That's why at half throttle you're engine is already revved out. No matter what jets you put in there it won't run right.

 

check out the throttle cable on that...maybe it is messing up the slide...mine was stretched and it made a huge difference just replacing the cable.

 

yeah i found that out so im putting the 180 back in it and a stopper on the twist til u guys recomend some mods for it then ill try again lol so shoot away whats the hmmm how to put this what mod do i need to reach the peak performance of this carb seeings im already goin fast enuff lol any advice is apprecated i as trying stay away from boring til i absolutely had too thanks sam found out same thing yest from factory racing and its about 3/4 throttle is wide open

 

man...please use some periods...i really dont understand your last post.

 

What I have found with the pwk carbs is that if it is rich at all it will run kinda like a 4-stroke from idle untill half throttle. Then it will break up and start sputtering. I would raise the clip a notch and keep going down on the main untill it will rev to the moon with no sputtering. Be careful thow! If it starts to "flatin" out then that means your getting to lean. On my honda 250R with the 38mm pwk with bolt ons only im at 162 and its real crisp, So there cant be to much diffrence in jetting between the two motors. 180 seems WAAY to rich for a stock motor with just bolt ons. SO, start going down on the jetting...... By the way the 38mm will NOT be to big for the motor with bolt ons. You will loose some bottom end but thats normal. The top end will make up for it once you get it dialed in.


*** if leaning the bike out dosent help then I bet you have an eletrical problem.

 

ok thanks man just got off phone with majic racing said same thing about the size carb and stock head said id lose bottom and recieve top thanks agn

 

lt, what boot are u using for the rad valve to the carb. the lt250r rad valve boot doesn't fit?? also how did u get the airbox boot on? that doesn't fit neither.

 

oh yes they will fit bro lmfao now its quite easy take the rad valve boot and put it in boiling water take out a spice bottle out your cabinet thats just a bit bigger then your carb put some butter on it and put in in the boot now let is stay in there 2 days ypur problem should be solved. i know this sounds funny but works. btw i used a mcormick montreal steak bottle lmfao. oh yeah for all to know i got my airstryker dialed in and it rippppppppppssssssss. the aitbox boot will fit to sam just takes some patience i about ran out.lol good luck ty all for the advice on the main .

 

i'll try it thanks!
