i was out last weeend with my brother i got a 04 500 he was a 04.5 600 with a pure polaris can on it. If we both take off at the sametime i can get a least a bike length head of him until i top out at 57mph then he can get by me.Is this normal?dont get me wrong im not complaining,but i think he is a little sore.

I also changed my spark plug on the weekendand it was black,should i lean it out a little?

 

Bubs, are you still running the stock air filter and muffler?

 

i got a k&n filter but the stock muffler

 

that k&n sucks a lot more air in the engine that why u get him until u top out - on most 4 strokes a pipe will just give more torque

 

hey Bubs how much did that K&N get ya at. thinking about gettin one

 

i think it was about $65 canadian,to tell you the truth the only benifit i see with it is you can wash it.

 

Hey Bubs if the plug is black its too rich also check the tail pipe its most likely black and sooty. With the K&N it should run a little leaner but try lifting the clip on the jet needle a notch or two and check the plug and tail pipe. I did this to mine and the tail pipe now is a greyish black and the plug a light tan.....

 

did you notice a difference in power after adjusting your needle?where did you get the 1.75 spacers?
