I just installed an EPI secondary black spring on my Prairie 650 and double checked the belt adjustment, and I haven't noticed any difference in acceleration. I was expecting to be popping wheelies which I couldn't do before because of the 6000 ft elevation where I live. EPI also sells a complete clutch kit for $199.00 and also the black primary spring. I'd appreciate any coments on my problem or those other products.

Thanks,

Is the motor jetted for 6K ft elevation?

 

alko,

Welcome to the forum.

Installing the black secondary is going to improve belt life and helps in backshifting. It won't do anything for your bottom end power. Do as trx450 states and make sure the bike is jetted for your elevation. Then if you want more bottom end add a module or wait on the cdi.

 

Yeah, Mike penland himself reccommended the jetting.
Thanks,
