No 1 and 3 cylinders not firing.

Hi there.Wonder if anyone could solve a problem I have with a Faser 600 (2000)Its been standing for awhile and now ive got it back on the road it refuses to fire on 1 and 3. Cleaned carbs checked all electrics rubbers diaphrams you name it. Just cant cure it.Above 3500rpm everythings fine.And if I start it on choke it gives me 4 cylinders but 1/2 mile up the road back to 2 stroke.Any ideas guys.Thanks.

Blocked pilot jets is the most likely problem.

Thanks Unfazed.Tried everything.Wynns carb cleaner and even changed the coils today which again resulted in 1/2 mile of back to normal running then gone again.Checked the carbs for sync and all was as it should be.The bikes done 23000 miles and never missed a beat until I was foolish enough to leave it standing in the garage for 2 years with the occasional firing up.Because of the problem with 1 and 3 not firing I didn't suspect the coils.

 You are going to have to remove the carbs.
Remove the float bowls and remove the pilot jets. I usually use good quality cellulose paint thinners to wash them and use a fine brass wire to poke through if necessary (I use the bristles of a soft brass brush), don't use anything else brass on brass does no harm but steel on brass will.
Be careful not to over tighten the brass jets and use good fitting screwdrivers and sockets.
