    Mikuni TM34 jetting

    I am no expert but that sounds way over jetted. Mine is bored to 750 and rephased using TM 34's. I started with PJ 25; 170 main; 5f3 needle. I was suffering terrible sooting. All way too rich. I am now down at a PJ 15; main 165 and a 6DH2 needle. When cold it backfires a lot but when...

    Clutch adjuster cover rattles

    Cheers gents. My o-ring kit is fairly industrial so I think I will go for the silicon option. Appreciate the advice.

    Clutch adjuster cover rattles

    XS650SE. The clutch adjuster has a chrome cover that you push in. Mine rattles. It's new. I have gently spread out the splines and now it does not push in quite so easily but it still rattles. It feels like there should be a small diameter rubber seal fitted to the cover? Am I missing a...

    Shift shaft lateral play and washer plate

    FYI, Fowlers have them. They seem to be a good source of UK OEM Yamaha parts. There is a replacement part number: 90201-14220

    Shift shaft lateral play and washer plate

    XS650SE, 1981. On the lhs of the engine where the gear shift shaft exits the crankcase there should be an oil seal, a washer plate, and then a circlip. I have misplaced the washer (part number 248 18137 0000). The only source I can see is CMSNL but they are very expensive for a UK buyer...

    Bewarethemoon, if you have time to dig out the measurements of the bearing spacer I would be appreciative. (BTW bike-parts-yam.com have been able to supply a flange washer for a few £'s)

    Mag rear wheel bearing spacer dimensions

    A very kind offer. I am fitting a Moto Lana swingarm (designed for an SR500) to a new Mikes XS hub and at the moment it is not decided if I will stick with the 20mm XS650 spindle or use a 17mm SR500 spindle. Until that is decided I will not know what diameter spacer I need and if an XS650 one...

    Mag rear wheel bearing spacer dimensions

    The rear wheel bearing spacer for a 1980 SE cannot be found in Europe, as far as I can see. I can get somebody to fabricate one for me but having the OEM dimensions would be handy. A google search can find the dimensions for drum brake XS650's (part no: 9056 020135). But the mag wheel has a...
