Project Ruby Racer (custom FZS600)

I suspect that's the cause of the nasty hesitation you're getting at 8-9,000rpm. Fitting pod filters considerably alters the fuelling and you need to make changes to the carbs to compensate. I'll be making another jet change in the next couple of weeks, well maybe early January now, so I'll let you know how I get on. The bike will eventually go on a dyno for proper set up.


Something else which also needs doing after changing the set up, however small a change, is to re balance the carbs.
