Improve engine performance on RMZ-250 2008

Recommended Posts

Hi!

I have a brand new suzuki RMZ 250 2008, and the frame feels so good, but I think that the engine is not so powerfull, I´d like to improve performance especially in the low and middle power band. What do you recomend me to do?? Exhaust, hot cams, C.D.I...? Thank you very much!!

I live in Spain, and I think that crowers has not distributor here, does HOT CAMS work well?? The same happens with the Pipe, we have akrapovik, pro circuit, fmf,yoshimura...but not bill´s. Why is better to enlarge gearing?? Thank you very much guys!!

hot cams will work fine crower just has a custom grind which is a little better the akrapovik is a great pipe runs same as bills we have run that one to. the gearing is almost the same just a little higher but changes how chain runs because of front sproket and also load on swing arm atleast thats what we were told by shawn hamlin and when we tryed it it worked asume almost everybody here now runs same gearing try it you wont be disapointed

Before You do all that, I would take the head off and get it ported. At least get the squish properly adjusted. Stock it comes 1.2-1.3, if You remove one slice of the head gasket, You should be back to 0.8-0.9, which is just perfect for that engine, and You can still run it on pump gas.

Getting thesuish tuned will cost You 0 zero (if You do it Your self) and You will gain bottom power.

I would suggest like piggdekk to try and get a higher compression, you could also look at a Pro circuit piston. Pipes doesnt do much if you look at the money. Insted look at this http://www.loudmouthmx.com/

I havent tried it myself but it sounds like its awsome: http://www.loudmouthmx.com/sitex/images/stories/good.jpg

Also getting your carb optimized will give you a lot of performance.

A CDI that removes the rev limiter will also help if you want more top end, i dont remember wich company makes it but do a google search on it :busted:

all the rmz needs for more top is a slip on pipe, it really wakes up the top end, i use the fmf speed silencer, feels like about 1.5hp alone with just the pipe, and it makes the power much wider.No loss on bottom or mid either.

Maybe a jetting issue. My 08 has so much bottom and mid range I have given up the idea of a big bore. I have an app. 3 mile H/S course on my property that I only use the clutch to keep from killing the motor when I come up to an extreme corner.
