Yamaha Workshop

I have a 2001 Yamaha Aerox that i have just bought, not in the best conditions if im honest but it starts, it can rev sometimes but not enough for it to move, it has a 70 kit fitted at some point and a doppler exhaust, 4.9g rollers, 21mm carb with size 86 main jet but im not sure what else, ive cleaned out the carb and jets and pit in some fresh oil. Could anyone please help me!!

Hi there I have a FZ6 Fazer 2004 which I have just bought here in Gibraltar. When the bike is warm the idle can suddenly drop and sometimes cuts out. The TPS was changed in 2007 and the diagnostics on it show the TPS to be working with no skipping of digits. It has done 20,000km. I have tried fuel injector cleaner but would appreciate your opinion. Cheers Gibfazer

Hey My 2009 XJ600 Is still restricted to 33 BHP because of a throttle body restriction , which prevents full throttle power . Its an official Yamaha restriction , the Standard throttle body was removed and replaced with the restrictive one . They gave me the original throttle body and told me to bring it back once my restricted licence is over . I have now lost the original throttle body and have been told ( by Yamaha dealer ) there's nothing they can do, the throttle body cannot be ordered or replaced . So am I wasting my time looking for a throttle body for this machine ? Would a Breakers be my best bet ? I can remember what the throttle body looks like and…

hi all i need to make an adjustable butterfly valve for the air intake on the xvs bobber but not too sure the best way to go about it.... i can make the round plate no probs....its just how to connect it to the "axle?"(the bit that controls the movement) and how to make it so i can control how far it opens or closes ect, the best idea iv come up with so far is to try and cut a bit of studding in half (legnthways) then wedge the plate in between, then stick a nut on each end to wedge it in the inlet pipe, but then comes the problem of controlling how far it opens... cause its replacing the original intake i need to move it at like 1mm increments to get the best ou…

a few days ago I visited my uncle and he has in his garage what i'v identified as a 1982 XS250R mostly together; the heads off and its sat for a little while but hes gotten it in a trade and the condition actualy looks fairly good for the age of the bike. however the issue is the 1982 appears to be a completely different shape to the rest of the XS250 series; while the bike is cosmeticly complete I don't mind ghetto mods if need be but how much of the engine is interchangeable from the earlier bikes? given the heads are off i'd be keen to do a 400 barrel conversion to get the extra oomph and stealth but if im going to be limited to 1 or 2 years production (alot of the …
