Hi all
Hope someone can help,as above bike sometimes stalls at junctions sometimes revs go high seems to have a misfire with my limited knowledge managed to change plugs and air filter checked coils still the same.borrowed a friend's laser temperature gun seem to have a problem with cylinder no4 temperature at headers only half of what the others are 1-3 380F no4 150F .Think it's beyond my knowledge now anyone recommend a local garage that would try sort it out will have to pick bike up as it's a nightmare to ride

Sounds like your carbs might need a good clean, assuming it's an older carbed model? as for a local garage that depends where you live

Thanks for reply live in billingham,might have a go at cleaning them when I put the bike to bed for winter is it an easy job

Yeah it's fairly easy to do if you know your way around a bike, as for a garage up that way I don't live around there so not sure.
