I think i will have to re check valves tomorrow as foreman back fires now when coming off the gass on overrun large bang and flame out of exhaust ????? only when warm so what now may be some thing else any clues any one , a new post mite be needed getting bit off topic !!
Yes exhaust valve was tight ?? couldnt get .006 feelers in so was extra carefull this time and both now set ,
Back fire gone except when i thrash it , so twice in one week makes me near a pro now !
Hope thats a end to that
