Low end power is much better now than stock, but besides jetting and pipe, I really lowered the gearing by putting a 49 on the rear and running 13, 14, or 15 up front. A 13/49 combination gets the bike into higher rpm range right away, but with a top running speed of not much more than 60. The 15/49 puts me real close to the 13/42 many others run around here. However, now that I've learned a little about how to ride in the dirt, the rear will be going to 45, maybe even back to the stock 42 after 351 kit is in. :D

I like 20/80 tires (street/dirt). Right now have a Kenda Trackmaster II on front, and a very inexpensive trials tire on the rear that I found on CL. I really like the trials tire and may get another after the two other new rear tires in the garage go away.

I'm running the Track master II front and back and love them

I figured out the bogging problem, turns out when i put the car back wrong the vent hose was against the xhaust, it melted it self shut so it couldnt vent, clipped the hoses and its running mint now, thanks alot ya'll!

Nice!!

I'm sorry but I've searched and searched for the honda pipe mod and can't find it even with the advanced search method. Can someone please tell me what you're talking about? I've got an 09 klx/sf that i knobbied. What honda exhaust are we swapping up to? Thank you very much in advance.

Try the dunlop 952 knobbies, aggressive tread , hard compound and cheap.
