dan28 Posted September 11, 2010 Share Posted September 11, 2010 the manual is very vague on this i know there is the black adjuster but in the manual it has a very small pic of this area Uploaded with ImageShack.us there should be some screws somewhere? click the pic to enlarge Link to comment Share on other sites More sharing options...
jattie Posted September 12, 2010 Share Posted September 12, 2010 The idle screw is normally a big one on the side of the carb. In most cases the come out on a user friendly extension cable. Link to comment Share on other sites More sharing options...
Paulwhite Posted September 12, 2010 Share Posted September 12, 2010 the idle screw makes contact with the round bit of the throttle (on the carb) just look where ur cable attachés to it and you should see it as to adjusting the fuel mixture there is only an air screw located on the side (a small brass screw on the opposite side of the float bowl) y do you want to change the mixture? if you want more fuel at top end then id suggest getting a bigger main jet think standard its a 90 in the drag so go get a 95 to make it richer, OR adjust the jet needle one notch (for the cheaper/safer option) but if your doing a re-jet then id warn you the extra fuel in the mix will cause your piston rings to wear down a little faster.

Paulwhite Posted September 17, 2010 Share Posted September 17, 2010 that sounds dodgy!!!!! i know the xvs engine is very temperamental! try going round it to see if everything is on properly! if there is a leek of any kind then it wont start. but why would they take the airbox off???? its got nothing to do with the mot! as long as the bike started and ran ok when you took it there then there is no need to go anywhere near the air box. if it was me id go mental and threaten legal action! at the end of the day they fooked it up! best bet would be to go down there and tell them you want it fixing! otherwise you will contact your solicitor! and take the bike to a Yamaha dealer to get looked at, to see whats wrong and sue them for the damage! hope you get it sorted m8!
