I just got a used Yoshi Slip-on for my '02 YZF-600R. The guy who gave it to me said that when he put it on, he re-jetted the carbs after a couple thousand miles...he bought some kit I think.
I asked him if I should do the same, and he described what a pain in the ass it is...apparently there are brass caps on the jets that are hard to work with, and it will void my warranty. To be honest, I would rather just not deal with it, and leave it as is.
He said possible consequences of not re-jetting are
1. The bike might run lean at high RPM's and possibly blow the engine
2. Generally running a little lean
3. The engine can 'pop' with sudden release of hard acceleration
Since installing it, I had the chance for a high speed highway run, and I did not experience any lack of power at all. In fact, it seemed to have even more push at and around 150 mph than it did before. The bike runs very smoothly, no popping noises on release of the throttle.
All in all, I would say that it runs better than before the stock pipe. Should I still re-jet? Could I hurt my bike if I don't? Bear in mind, money is pretty tight right now, and I can only afford to perform necessity work on it.
Thanks guys!
