asmudgexj600 Posted April 30, 2009 Share Posted April 30, 2009 Hi all, I hope you can help. I finally fixed the oil leek problem with my xj600 (is anyone else has the problem, the way I fixed it is on the bar forum) I went for a ride yesterday, everything was fine, but my top speed was 70mph in wind, almost 80 on flat no wind. Should I expect this top speed from a 1998 xj600 n which hasn't been too well looked after (till me!) If not, any suggestions as to what's wrong? Thanks for any help.

Hi, thats well down on power ! a ton will be no problem for the 600. I will state the obvious but there maybe something you over looked ! 1) Valve Clearance correct ? 2) Air cleaner clear ? 3) Compression good ? 4) Carbs clean & adjusted correctly ? 5) Ignition circut & boxes working correctly ? 6) Valve timing correct ? perhaps check some of these out in order to eliminate them from the problem Regards Jim Link to comment Share on other sites More sharing options...

asmudgexj600 Posted April 30, 2009 Author Share Posted April 30, 2009 Sorry for more obvious questions, but what tools do I need for those? I assume I need a compression gage and vacuum gage for the carbs. what else? Link to comment Share on other sites More sharing options...

I assume I need a compression gage and vacuum gage for the carbs. what else? Hi check Compression - a compression guage A vaccum guage (or set of) would not be needed until you have a correct compression reading, Correct valve timing and the ignition correct. with these correct you could look at other 600 divi points. but as ur bike has been not looked after there is a chance that one of the above will cure it To check valve timming you will just need general tools, spanners allen keys etc and a bit of time Ignition - a multi meter would be a help Carbs - general tools to strip them and when everything else is done & the motor running vaccum gauges to check the balance but I would guess you would have a compression/valve time problem, when you post a bit more there is a chance the correct problem could be found.
