No the dyno printout was 15 years ago it made 6 hp more at mid range & 4 hp more at the top end the exhaust is a standard can with the reflected system removed and an absobtion tube fitted

I rekon a new set of carbs is the answer the old ones must still be blocked shame the bike has only done 7000 miles

Thanks for the suggestions

Hi,

Have you drained the tank and put fresh fuel in?

Yes I cleaned out the tank but while I am working on the bike at the moment I use a dummy tank that holds a litre or so of fuel

I have identified this afternoon by a process of elimination that cylinder no 1 in is at fault has a spark & compression but no fuel so it looks as if a new set of carbs are required

anyone have a set for sale or know someone who has ?

Thanks

Paul
