The spark appears to be a bit weak on the old XS, does anyone have any recommendations on where to source some

New coils from, don't really want to end up with some cheapo nasty Chinese tat 'tis all.

Or any ideas why spark would be weak, have new plugs,leads fitted already.

Cheers Jak....

jak,

check earthing from battery to engine and to frame (take off and see bright metal then wd40/acf50 it)

Is it TCI or contacts?

I got new coils from rex caunt racing http://www.rexcauntracing.com/pages/htcoils.html

Well today was a failure as far the XS goes, but.... got the rear wheel hub swapped out on the Mundaneo and got the lawns cut (under her orders,that one)...Checked everything on the XS as far as connections goes and all appears OK, even swapped the coils for some I found in the bottom of a box o bits, still wouldn't start, flattened battery twice and got tired trying to kick it off so resorted to swearing and kicking the bike as well.....It may come as no surprise that that didn't work either...... Oh, well back the beginning another day...... :shakeno:

start from scratch, take points out and dress them, clean with contact spray. put back in the right order so they don't earth out to the engine.

set timing

check red/white to coils for power

take off ht caps and re-wind them back in after checking the core it in contact with the caps

re-time valves.
