Help RMZ250

Recommended Posts

Hi guys, I need some advice please. I have a 2009 RMZ250 with loads of mods but the bike really still isn't that fast and I think I have done something wrong.

I have:

CP High compression piston,

I polished the ports but did not change anything(just polish),

Hotcams stage 2 cams,

Quickshot 3 accelerator pump,

Akrapovic Exhaust (I also have an FMF),

Vortex Ignition.

I am 5300 feet above sea and average temperature around 23 degrees celsius. The bike seems to run very rough after 2 or 3 laps (spluttering or missing?) especially out of turns and rolling off the throttle. I have been using 95 octane pump gas and stock gearing.

At the moment my jetting specs are:

Main 172

Pilot 40

Needle standard

Needle clip 2nd from top

Please help me get my bike to come alive!! I am also not sure what ignition map to use etc? I am lost at the moment.

Thank you for your time.

I would not run 95 octane on a high compression engine,

Run 98 octane or what ever is the highest pump gas you can get from the petrol station in your country, ausstralia's is 98
