Non starting XBR

[SteveC#222]

I've had my XBR laid up for the best part of a year now - various reasons but mostly crap weather!

I haven't been running it, but it has been kicked over from time to time.  I tried to start it the other day but absolutely no go. Fully charged battery, new petrol ( tank & carb drained before lay up) compression ... nothing. Engine is turning, fuel is getting through ( wet plug) but, with the plug resting on the head, no spark. I've tried changing the CDI and the cdi/plug cap and plug, still no spark, tried hotwiring the kill switch, no go....hmmmmm

Last night I noticed on the wiring diagram there is a side stand cut out switch!....could be that but... where does the little bu55er live! Can anyone point me towards it and it's connector or even suggest something I haven't thought of?

The only thing I've done to the bike in lay up was to adjust the valve clearences, but I'm pretty sure I got it right.

thanks

I can only speak of my bike, but there is no side stand kill switch on it, it's a F reg!!

Just realised the wiring diagram I found marked up as 'XBR 500' actually says 'GB 500' in the top corner!.....No wonder I couldn't find the little bu66er!.......back to the drawing board.

Mine was the exciter coil on the stator. Manual says check for continuity between the single wire from generator (Black/red I think) with earth. If no continuity its nakked. £115 from wemoto!

Check the carb. See if it is clean or gummed up. I know you have petrol getting through but the carb may still be a mess.

Hang just re read the post

Change the easy stuff, plug, plug cap, ht lead etc.................

As an alternative, check the kill switch, we have all done it   but maybe some corrosion has set in.........
