FZRSupport: the FZROnline Archive

I've just purchased a UNI foam filter for my FZR 600. It states that the bike may need to be rejetted. Does anybody here have an UNI or K&N filter on their FZR and needed to rejet their carburetors?

I found my answer and my carbs don't need to be rejetted. The following details are from powersports.net and from motorcyce-superstore.com:

UNI OEM REPLACEMENT AIR FILTERS

*Fits exactly like the original equipment air filter
*High flow Uni-filter will improve performance and provide the best filtration and engine protection available
*Uni-filters can be easily cleaned and reused
*“Flow Matched” filters need no rejetting

The basic rule for re-jetting is that "if no more power is going out, then no more power is going in". In a nutshell, unless you modify your exhaust, then chances are, the motor is not pulling in any more air regardless of the filtration change.

That rule doesn't necessarily apply to forced air systems... blowers, superchargers.

Thanks for your response...will keep that in mind...
