[QUOTE="helio lucas, post: 1400329, member: 78346"] plus, a 4 cylinder exhaust can be more efficient than a single exhaust per cylinder even more with exhaust valve (like yamaha exup), the same on inlet side. not to mention friction losses and some other things that are just too ***** to compare. the valve out of adjustment thing has an explanation: the guy bent his frame and since the head is fastened to the frame it bents as well. simple, then just adjust the valves and you ready to go. i know this is the thumper forum but no need to speak in a depreciatory way of smokers like that. i still like them :fft: and ol'89r, never look again to my bike please. despite my bike is a two stroke without exhaust valve you may well throw my ports out of spec. and no... don´t even think on my bike!!! but you may think in gomer hard and throw his exhaust valve out of adjustment :uh: mxcrazed, the fact that you have bought a 250 km/h bike that has crashed at least two times tells a lot of what you look for in your bikes. you may need a quad. :ride: [/QUOTE]
