Had the following kit in the LML 125 for a few weeks now, thanks to Adrian and Curare for getting me going:
SI 26/26 with 190 air corrector, BE4 mixer, 125 main
timing set at 20 deg btdc
Initially thought that the 125 main would be rich but plug electrode is brown so have stuck with it. Advanced the timing slightly to 20 and have checked it with strobe. Question is should the timing marks align at tickover or cruising speed rpm? As it is at tickover the flywheel mark aligns with the „IT“ mark on the casing at tickover and then advances towards the „A“ as rpm increases. I suppose that the ignition is supposed to auto advance in this way but if someone could confirm it would be helpful.
Also, when the bike pulls away from standstill it stutters slightly, initially, as the throttle is opened and then accelerates smoothly to full throttle. Maybe my carb setup could be better? Just unsure of what to change. The kit is just about run in now, I’ve had it slightly over 60. It’s crying out for longer gearing but that can come later.
As usual, all advice much appreciated. AK
