I am looking for the best clutch/jet/etc. recipe for my 2001 ZRT 600. I like to do some trail riding and some lake riding and lake 1/4 mile blasts with my buddies. I have an EPI clutch on it now, but I am not liking it much as other sleds I have been on with clutches. I also have a D&D can on it but it is otherwise stock.

I know the guys here pretty much have this sort of thing nailed down, so what advice can anyone provide me?

Thanks in advance,
Jason

Thanks, but I am looking for the recipes that people have that I can pretty much print out and take to my shop to get the parts. I know I have seen some tried and true power recipes.

BTW...anyone know what a stock 2001 ZRT 600 jets are? Can't seem to find the info.

I'm looking for that info too. Stock main jets are 310's for an 01 zrt 600 with the mikuni flatslide 36mm carbs. What needle position do you run with. I would also like the recipe to liven up the cat. Would a D&D clutch kit help it out. Please share your recipe.

I've been looking for the same type of info, mainly to squeeze some more fuel mileage out of it. Mine smokes profusely when cold, so I have a feeling that it's over-oiling. 310 mains are stock, going to 300's will help. Look at changing some gearing, as well.

I'm not too eager to put a wrench to mine, as I have a feeling that our snow is gone for the season, and this sled will not be around next year.

Snow's gone already. We have plenty still. Mine smokes like it's on fire too. I've been running 300's this year.

I have 310 jets, powerbreather, v-force 3 reeds and an MBRP can installed on mine. After installing these I had to adjust the air and fuel screws to get it to run better at bottom end. This cut the smoke at least in half. May need to try that. Also running 10-54 weights and a D&D 56/52 helix with red spring in middle hole and primary spring is an erlinson brown I believe. Need about a 310 or 320 lb finish with about a 125 start or 130lb start. Works really well, comes out of the hole hard, and lots of top end still.

I've got a D&D clutch kit I'm thinking about using. It comes with 10-56 weights, DD6 helix - says to more secondary spring to 4th hole and comes with a blue primary spring (170-265). The instructions say that it should engage 4800 and shift at 8200. Someone also mentioned using the Arctic cat orange-white primary spring (143-290). This spring would appear to engage at a little lower RPM and shift higher? The stock spring is the Arctic cat yellow-green (114-267) and I think it engages around 4500 and shifts around 8000 with the stock 53 gram weights. The stock secondary is a 55/53 helix with the red-white spring. Anyone know the angles on the D&D DD6 helix?

I believe a DD6 is a 58/37. The engagement might be high, wich it doesn't need to be with the APV engines. They make good power at lower RPM's.
