First of all, Paul Turner pipes are a waste on that motor....get better pipes as money allows.

 

Second, your pilot is WAY fat....the fact that you have to turn out the air screw 3.5 turns is evident of that. Main sounds sorta close.

 

get a 48 and a 50 pilot, 1.5 turns out on the air screw...start there.

Also need to check your ignition, ohm the stator, ohm the plug caps or replace them, fresh gas and oil, fresh spark plugs, etc.

 

I'm assuming this bike ran before...etc. Did you do a compression and leak down test? Is this a fresh build?

Where in MI are you?

The Ptr's will hold back peak power and higher rpms, but they will make that motor more tamed and smoother power. If your trying to ride this thing, then keep the ptr's, if you just put around to drag others, then get some other pipes..CPI, shearers, etc. As for jetting, I find the 34PJ like more fuel then the PWK's....55-58 pilot, 172 mains, DEK needle on the 3rd clip should get you close. Adjust your air screw for best throttle response...If it likes to be at 3.5 turns out, then the pilot is too rich...A rich pilot will make your shee start great when cold, but hard when warmed up....Did you disconnect the tors?

First thanks for the help before hand. ,

 

I know the pipes arent the best but I do alot riding in the woods and through apple orchards. No I have never got the thing to run, I just got it rebuild and have been to rejet it, pistons are brand new and I have 140psi on both sides, I live in kent city michigan, about 20 minutes north of Grand rapids. I ll put the smaller pilots in and see what happens. hopefully this works, stator and spark plug wires are brand new.and I have dek needles 3rd clip.

 

thanks lot everyone.

How many times should I kick it over before, I should change anyting? I have been kicking it over about 20 times. MY right leg is huge now. It still just rolls over like three or four times on its own then dies, 40 pilot, 160 main, air screw out 1.5 turns

 

any help would be great.
