Curious - how much difference does a couple of degrees of ignition timing advance make on the performance of the engine? Noticeable or negligible?
I’m going to check mine this weekend. The video I watched was old and I’m pretty sure I adjusted it last season.Thanks Jim, will read up. Reason I ask is I was watching an old vid of the timing on my XS and it looks like I may be several degrees retarded. Didn't know if it was worth adjusting it.
Correct.I have no timing strobe light yet and I'm impatient... If I wanna turn my points plate just a smidge to retsrd my timing and try to avoid kickback and backfiring, which way would I turn it? I assume clockwise advances timing..? The engine camshaft rotated towards the front (counterclockwise from the left side of the bike) which means turning it clockwise would help it meet it's mark sooner, yes? Correct me if I'm wrong.
To be honest, I just set them to be level with the mating surface of the bowls.When you set your floats, did you set them at 25mm? That's the spec for the '76-'77 carb set, not 24mm like some of the other BS38 carbs used in other years. 24mm would be a richer setting.
I can say this though, I turned the screws out to a full 3 turns out and it didn't backfire a single bit. My timing is pretty close too. Gonna make a post on my build thread with a video showing where it's at.To be honest, I just set them to be level with the mating surface of the bowls.
Not sure if it helps .But one way to dial in ignition is toI'm just taking blind guesses without a light... It backfired out of the carbs before. I made an adjustment and now it backfired out of the exhaust. I'm investing in a light that displays rpm and a few other cool things here soon... but I really just wanna figure out my fuel mixture and I gotta have my timing right first lol.
