Hi

I got this bike for a very fair price, but the kink is that it wont start.

When you kick it (kick only) it will give a pop or a series of pops but never more than that. The combustion sounds nice, no wierd sounds and if I increase the idle the pops will also come more frequently - when the bike decides to give them!

I have have tried to give it some brake cleaner in the fuelfilter (to check if it was gas starvation) and that did pretty much nothing.

I checked the valve clerance and it was ok.

If I dont use the decompression lever, then the bike is very difficult to kick so I think that there is compression.

The previous owner said that he started it after a long winter break and he rode round the block and it just died (wouldent react to the throttle) and since then he could not start it.

The carb has been cleaned and appears to be in good working order. The idle jet is a "50", the stock is a "45". The bike has an aftermarket exhaust which restricts alot less so I suspect that is why.

When I got it the pilot screw was backed out 8 and 1/4 turns and I have read elsewhere that standart is around 2 and 1/2 turns. But adjustments to the pilot screw seem to have no apparent effect on the starting difficulties.

Any ideas? Cracked piston? Rusty valves?
