1999 Honda CRR 600F4 Jet Kit
Hello Folks!
Since I bought the bike a couple years ago I have been living with flat spots in the upper RPM range. This issue is especially noticible when the ambient temp is up above 80 degrees fahrenheit. If I drive the posted speed limit the problem is not noticeable...which is next to impossible.
I have a K&N air filter and a full header back M4 exhaust. I have tried sea foam, replaced the plugs and fuel filter, without much affect.
I asked my local shop what stage kit they recommend and they said Stage 2. Dynojet only makes a stage 1. Still trying to search other jetting companies. I emailed Factorypro in CA but there website looks defunct.
Has anyone out there installed a stage 2 kit on 600f4 with similar mods?
What other companies besides Dynojet can people recommend?
Thanks for your help!!
