91 650 SN bought as stock. Over the winter, added Coffman's Sizzler(rejetted and changed N&S), bored the nozzle, lightened the flywheel, put on a 13/17 prop. Defoamed and refoamed.
Better than last year but still, compared to my modded 701 it's like a Yugo versus an AC Cobra.
So how do I get more pep? Is there a decent aftermarket head for the 650?
Is the stock CDI holding me back?
Can I have a stock 701 CDI modded to remove rev limiter and use that with my 650 electrics? I read somewhere that the stock 650 CDI has a lower rev limit than stock 701? Is swapping stock for stock worth it?
And yes, I know..it's a 650, why didn't I just throw in a 701 or 760?? Good question.
As far as the 650 goes do I just have to live with the 'you can't polish a turd scenario?"
