BF650i performance

[Jonesin']

I have a '07 BF650i and I am looking for suggestions to get it to "hook up" or "launch" better. I want some low and mid range power. I don't us the top speed very often, Only when travel to and from the Farm. I have 26" Mudlite XTR's on factory steel wheels, no other mods. Any suggestions?

You want to put the EPI burgundy spring in the primary clutch. It will give you a little more engagement rpm and it will be more responsive down low and hit the tires a little harder. You will really notice it in the mud. I've installed lots of these springs in BF's Twin Peaks and 650 Cats and not had one customer than didn't like it. If you need anything else or some more power give me a call. Dan, Extreme Machines 403.748.2219

Either a VDI or Dyna tech ignition. They help alot! I also recommend a jet kit and aftermarket exhaust. Kawis respond good to those mods!

I am curious which one is the burgundy spring as it is not on EPI's website?
I have the maroon primary in my 750 and love the difference over stock, quite a bit more bottom end it seems like.

put an hmf on her and let her bark....... dyna tech cdi works awsome, i put the highlifter superduty clutch kit in my brute im only runnin 27'' lites now and the bottom end is really good, flip yeah over bsckwards if your not easy on the gas and you get good traction.

Maroon Primary spring it is then and maybe an ignition mod. Thanks to all who responded. As I said before and will continue to say, this is a great site with great people.

id put a pipe and jet kit it would really wake it up.

I actually have a dynatek i could sell if you want. I found it today when i was cleaning. I took it off my 650 when i traded it in and i was going to sell it and i forgot about it.

[Bruteskeg]

if you wanna wake that thing up you could allways put some high compression pistons and a cam in it ...

Ive got a 2008 650i And i ask the same question .I put a hmf penland pro exhaust on it and a k&n air filter and a epi clutch kit and changed the jets to a 140 front and rear and put a chip in it and also changed the needles WOW you want bottom end torque and power, do all that stuff.
