Jawa 350 638 from Letonia tuned with electronic ignition by gotronic

I like the LEDs on the spark units. You ought to put those someplace where they can be seen at night. Ha ha. It's really cool. You need MORE tuning though. Porting, PIPES, head modifications, etc etc etc. I'd love to see one tuned as an RD/RZ killer!
