well those pics don't seem to show allot but it looks the same

BAH

do you know what colour spring you have in the dump valve...?

just opened it up, it has a blue spring

BAH

that should be ok then, mine runs with blue ive also tried a red one and it doesnt dump at low revs so maybe its faulty, or incorectly fitted

Just got a replacment from forge - these guys seem good replacemnt was on the door step next morning, This one seems to be working but does not seem to sound all the time, after about 3000 revs when going for it it will blow off with out fail but when Im round town it seems reluctent to blow, Some times even over 3000 revs, I am running it on the yellow spring, If I sit stationnairy and rev the engine it does not make any noice regardless of revs - should I return the dam thing and get my money back, forge say its a option

BAH

thats normal
