Hmm...maybe I am reading it wrong? Or the factory cams are pretty good...have to remember first cut at cams for the LTR too.

Peaked up 1 HP max and 1 ft/lb TQ max, average did not change at all???? I was hoping for more...like 2 HP and 2 ft/lb TQ...average

Also, no tuning with PIMM/FIMAK...hmm...

Hmm, maybe my nubers are too optomistic, can not find a graph for the TRX with just a cam change from stock to aftermarket...I will keep looking.

Yeah after getting rid of the restrictive airbox and putting on a PIM module, I noticed the cams aren't as bad as I had originally thought. I was sure they were signing off really soon. It turned out that the airbox was causing the motor to just sign off. A good breathing setup with a good box(PIM) is pleasing me for now.

wonder what the specs are on those.i installed the yosh intake cam on mine and noticed a pretty good increase.at the track i normally practice on when my quad was stock i would hav to click 4th gear and pin it to clear he top to clear this step up tripple it has.when i did the cp piston porting airbox mods i could do the jump in third pinned and clear the top about a quadlength.after i added the intake cam i could clear it in third tapped by about 2 -2.5 quad lengths.im thinking that is more than one hp.i will have to try to get the specs and compare

If you can properly tune the computer to work with the cam it would gain alot more, unfortunetely there aren't many good tuning programs for the ltr450 yet, other than a few programmers..
