since dave and corey are probably the 2 best poo mechanics i know, i'm asking for input.
stock 155
1700 mi, rebuilt primary stock secondary w/ stiffer spring stock helix
sled start to slip/miss the belt when it was punched at 1/2 throttle.
Cleaned everything and replaced belts and pri spring......then while towing out a dead sled it got really bad. Cleaned everything again, last ride on hard snow.....sled felt like a it had 50% less power, and would not go past 7500rpm....was tuned for 8250....complete turd....felt like a 440 at 10k.
Upon inspection found, vacuum hose from ex valves disconnected from pump...and a ton of belt dust again....could stuck valves cause this?
Torn ex valve diaphams?
Tomorrow, tearing down ex valves and clutches.......ideas?
We also have another 11 assualt doing the exact same thing.
