You can make a good argument for not going over about 35° or so... I run my bike at 35° and it's just as happy as it was at 40°. I like having that 5° buffer 'tween me and detonation.Leave it there then if it takes throttle well. (talking about carb needles)
It's good, mostly required, to set the initial timing statically. However, especially since you have a PMA rotor, it's much better to set the timing with a strobe and verify that the advanced timing above 2000rpm is not more than 40degrees before TDC
Makes sense to me. At the pump here I have the choice of 87 and 91 octane. Ive been runnimg 91 in the bike. The Mikes XS that gave many angry hours of frustration seem to only run at 40° btdc or it didnt run at all. And it had to be fully advanced. Well advanced as far as the crappy unit will allow. If it was retarded at all the engine wouldnt run. I went from a 77 engine with odo of 9k to the 80 with 4k or at least read 4k and hours behind the wheel to pick it up because of that ignition system. Now I know why there isnt shit for videos of them being installed such a joke. And thag PMA kit they sold cost me more than I paid for the bike it self. I harvest maple syrup in the spring and I got the 77 for $450 and a pint of my syrup.You can make a good argument for not going over about 35° or so...

I will put the degree wheel on it and make sure it is advancing to the 35° mark. Many thanks to you gentlemen!Makes sense to me. At the pump here I have the choice of 87 and 91 octane.

I was probably pretty damn close to that with the last ignition I was running.Again, not to scare you but... this is what too advance "can" do. This is from the thread I linked to above. It's a good read. I highly recommend it.

This is the one I was mentioning, not pricey and always powered my ignition with no problems.The bike was charging. But I still installed my 12volt 5ah battery. I found a small one mentioned earlier the size of a cig pack. But the price is a bit high.

Apples to oranges, but we NEVER ran more than 36 degrees in the low compression Formula Vees.You can make a good argument for not going over about 35° or so... I run my bike at 35° and it's just as happy as it was at 40°. I like having that 5° buffer 'tween me and detonation.

Road the bike for a couple days. Bike seems to be working pretty hard. When I go a few miles and come to a stop it does not want to take throttle until its past 1/4 throttle. Will adjust mixture screw? Not sure.The bike last night did feel like it took alot of throttle to get moving. Different than last ignition. Wonder if I should move the clip up one? That would put it in the middle.
