I just installed a PVL (Penton) digital ignition into another bike...a vintage YZ125. The ignition is lightning in a bottle!!! Seriously, it feels like it revs 30% faster and %20 higher than the stocker did. The bike would not idle before, and without jetting or mixture changes, it idles fine now. The only hitch is that it isn't cheap at $475. But that includes everything you will need except a good spark plug boot. It comes with one of those little ones that look more at home on my weed-eater. Hope this helps.
