28 pwk's possible problem

[rtcc]

ok, so long story short I have been running my new 28 pwks for about 5 months now. I have got the jetting dialed in for the most part.

 

My mods are

>Paul Turner High revs/ FMF powercore silencers

>noss head 20cc domes

>RM stator w/+4 timing

>Kehien PWK 28mm carbs

>Ported stock reed cages w/TDR reeds

 

I am running 148 mains and 38 pilots. The needle is on the second notch from the top.The pilots are 2.5 turns OUT.

 

The top and mid range I feel are perfect. Plug chops look great, everything. The bottom right off idle (pilots) is still boggy and sputters. Now if the temp is 60F or below it runs decent and I can get away with the pilots being so mushy, but now that the temp has hit 70's I am fouling plugs almost as soon as the thing starts. If I put around for more than 15 seconds they start to foul out. I have no idea why my bike likes such small pilots but it does, I have never had in bigger than stock pilots when I had stock carbs.

 

I have a new stator, new coil and new plug caps. The thing is I still have to use the chokes to start the thing but I turn them off as soon as it is running or they will foul out. Im not sure what to do. I was gonna order smaller pilots but jetrus doesnt even have any smaller than 38's!! Also, the needles that came with the carbs have no markings at all on them, I have no idea which ones they are.

 

Could it be something else with the carbs? They are really clean and look almost brand new. The insides look great as well.

 

I dont know what to do at this point.

 

thanks for the help guys

nothing?

could there be something else I can adjust, like the chokes or something?
