My mate dumped his dt at mine after walking for 3 hours with it so I'm trying to look into it fixing it.
We were riding no problem, ended up stopping for a bit then when he started it he then stalled or it cut out not too sure. Then it would turn but not fire up.
I've stripped it down as I was assuming there wasn't enough fuel getting through and swapped the carb for one that I know 100% works.
The spark plug is now wet with petrol and there is a strong spark (by the looks of it)
Compression seems ok but I haven't tested it.
Kind of lost for ideas as it all seems ok to be honest - any advice appreciated I know it's a boring subject!
A old TZR I had did the same realy stumped for a while and turned out to be air leak round the power valve . used some silcone sealant smeared round the are just to test and hay presto .
but could also be other reasons hard tp tell with out seeing the bike .
you tried another spark plug ? it could be a great spark when out of bike but maybe week once . try to start it in the dark with plug tight in the bikewith some one looking close at spark plug to see if you can see any spark or blueflash around the base of the plug .
or do as my dad did to me as a kid say to some one here hold this for me a second then kick the bike over -if they call you names you know its a good spark lol
