I’m leaning that way simply due to the recommendations and they publish a nice installation manual, and make an install kit for our bikes.
What would you recommend for my engine as a safe redline now? The crank balance came with paper work saying good to 14,000, that’s well north of my comfort zone!
Part of my desire for upgrade is a rev limit as I have a garage full of more powerful bikes and sometimes it’s easy to forget your on the old beast when your having a good time in the twisty mountain roads!
There isn't much gain over 9,500 RPM. With the porting and good carbs the power won't fall off over 10,000 RPM. There isn't much point in putting the spurs to it and revving past there.
