Why does the '01 ZRT600 have APVs and the '01 ZRT800 does not? *Can you put APV on the 800? *Am still considering buying a leftover ZRT800 and noticed this difference.

I would guess they didn't want to spend the money on a eng. they were going to drop. Don't some of the after mkt mfgs ofer valves on the big bore kits for the 800 trip? This is the only way I can think of to valve it.

No offence, but have you ever had the chance to ride a ZRT800 or a T-cat? *

I have, and I do not think they need APV's. *These tripples have plenty of of low end pull... IMO

6Mile, I owned a ZRT800 for 5 yrs b-4 my ZR. *The power valves would give it better acceleration, to prove it, ride a ZRT600 w/them and one w/out, you'll notice a difference! *I just don't understand why they put them in the 600 and not the 800, knowing that niether engine would be around much longer.

Intersting. *I thought they were in the 800s also... http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/sleepy.gif *No idea why they didn't put them in, other than being penny pinchers.haha *Maybe they didn't work as well on the 800 motor as the others or was better off without? *Doesn't make any sense... http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/confused.gif
