Bittern Posted November 15, 2007 Share Posted November 15, 2007 Hi guys, I've just bought my dads XS400SE 1981 ( he's just got the 650 version) anyway i want to get it on the road but i'm restricted to the 33bhp license. My local bike shops want to charge me 200 quid for the privelige of a couple of washers in the intake manifold to restrict it. Well i want to make my own up as I'm not gonna pay £200 for a pair of washers!! Could anyone help me with how much of an opening should be left in the washer?? I've attempted to make a few up and ill post a picture, any comments welcome. Also does anyone know of a dyno in cornwall where i can go to get it tested?? Cheers, Rich Link to comment Share on other sites More sharing options...

Cheers, Rich I'd get it dynoed first as it may be making 33bhp already (i know the factory states 39hp) get your print out and you have the proof.

Rich Its automatic, but you need to check the blades on the chain as they wear. Link to comment Share on other sites More sharing options...
Bittern Posted November 18, 2007 Author Share Posted November 18, 2007 Could you tell me how to do this please? Is it a job where you need to strip the cylinder head? Cheers, Rich Link to comment Share on other sites More sharing options...

Cheers, Rich you need a haynes manual (plenty on ebay) you just need to take the cam cover off (undoing the bolts in the right order or you will warp the cover) and release the tensioner but first compressing it and lock it using a 2/3mm screw. the blades will lift out (front and back) either side of the cam chain.

Cheers, Rich hi its the paper work you are paying for, shop has to fit them and stamp certificate, ins company asks for certificate. otherwise they will not insure it. re dyno, i think you are wasting money £200 seems a bit much, my son was charged £130. shop around.
