The 800 was not too bad, but the 600 seemed to hold back for the first 30-40 feet on each pass. Could have used a little SNOW on the track. Besides the dirt flying you could smell the heated plastic smell on the top end of most runs.1000 feet track, hard pack dirt
Comparing sleds that are not broken in on dirt. I couldn't care less. Test them on snow after a thousand miles and then get back to me....:thumbsup:Did they measure the "fun factor"?
At least we still got that after this devastating dirt race!...first Livingstons scientific results and now this?
My take on cat, 13.5 -1 comp, tight exhaust and timing made 162 hp a long time ago. Fine if h20 temps stayed low, but deto city when water got warm.
So they loosened up exhaust. took timing away and have settled on a 153 hp sled for years now.
If I was them, Lower comp 12.5 to 1, redesign squish and bowl, add 2-3 degrees timing to 8000 rpm, take 2 degrees away from 8000, to 8250, 4 degrees at 8500 redesign the crappy y pipe, put real reeds in it, slightly tighten exhaust, they would be at 163 to 165 hp. And go to 8400 rpm.
Why cat didn't do this I don't know, they have a pipe temp sensor and det sensor that will save the engine.
Put a team tied on it also, looks like the new secondary has issues already..
I'm a idiot and I figured it out.:bc:
Edit, Basically cat stopped doing any R&D on the old zuk, and living with what they have, doo and poo keep adjusting.
