421 jetting 34 pjs

[bry]

br7es spark plugs in now but it had br6es plugs before i changed the huge main jet.

still acts like its super rich like you cant clean it out at all ??

You should be running B8ES spark plugs with gas. Could possibly be some of your problem there. I think those are a colder plug, not really sure what it would affect though but definitely try the other plug 1st. Who told you to run those?

Who told you to run those? i was told by yamaha that b6es plugs were hotter than 7s 18cc domes with 110 gas mix ratio 32-1 castor 927 is what i run in both of my banshees. thought it might be a crank seal bad but no luck they were both good! Will start checking electrical stuff tommorrow..

also i have black liqiud running out of my silencers??? Edited March 10, 2009 by bry

you need to be at like a 50 pilot +/- size or 2

middle clip on a good needle

150-158mains for your weather i live same conditions as you im 3 hr away.

 

 

you need to see what needle you have.

 

also do you have a good stator it could be cutting out on the top end they have been known to happen.

i honestly havent checked the pilot to see what it is i believe the needle is a cl but dont quote me on that had it apart so many times i forgot but its in the middle clip and running 150 s for mains.as for the stator it a stocker any suggestions on a good stator ive bought ricky stators before and got 2 bad ones rather not do it again..
