but..how do you do it?

 

I believe you RETARD the EXHAUST cam ONE TOOTH......

 

Correct.

 

If you go to yfz central.com and click on reviews it's at the bottom. It has pictures and tells you exactly what to do. I added a exhaust and filter at the same time I did the Cam Mod, so I'm not sure what the difference would be. I know it's faster than my 03 Raptor with the same mods. I mean alot faster!

 

I hear some have a tough time starting their quad after the mod. Any guesses to why that may be? (I have a friend looking at the mod.)

 

The decompression mechanism is no longer correctly aligned, that is why some just buy the YZ cam and install it, keeping the decompression mechanism properly aligned. Some seem to have problems, others don't have any. Seems hit or miss.
