Athame57:
I'll be watching progress with interest! ;)
blackeagles:
well, finally got the carbs back on and only pipes 1 and 2 getting hot - 3 and 4 stone cold - so carbs back off and appart again!!
back on and still cold so back off but i still could not find anything wrong so back on and blow me it started and ran with all pipes getting hot!! it does not like choke at all and will start with it fully off but it starts ;D. clearly its too rich (settings on basic i.e 2 turns out of the pilot screw) so will have to adjust - (which way to weaken, in or out)
can the primary chain be adjusted or is it set and the engine has to be taken appart?
progress, slow but its there :-[
Rozabikes Tim:
Primary chain not adjustable but sort and balance the carbs before worrying. That can transform things.
mike the bike:
Best to synchronise carbs. Unsynchronised carbs will make the engine sound rather rattly, whi h leads people to think the primary chain and cam chain are worn.
blackeagles:
ok, do you guys have your own gauge sets or just find a friendly bike shop?
most of the 'kits' i see advertised seem to use m5 for the bit that screws into the carb but i'm pretty sure the gauge hole on mine is smaller.
