Ok, so... I've finally almost got the old girl together. I've installed a 136x2 track, along with 7" drivers and a skidframe from a 96 ditch pickle ZRT or Powder Special.
The engine is a stock rebuild right now, with cleaned transfers and that's about it. I have a set of 36mm Mikuni's from an old Liquifire 440 I want to run on it that are soaking as I type this. I'm planning to do the SX cut on the piston and cleaning up the exhaust ports as well after this season is over. It still has the single SPI pipe on it and I'm also thinking of trimming the exhaust manifold up a bit as well.
Can anyone give me some sort of baseline to start with on these carb's? Will 36 rounds even be enough? I'm thinking they will be kinda lean right now. I think they have power jets in them, as there's an extra couple jets in the bottom of the bowl. I can't remember what jets are in them now, but the slides are 3.5's.
Also, I'm not really sure what to do with the clutching. I'm sure its fairly stock in there now, nothing wild. Any ideas how this will work with the stock gearing but smaller drivers on it? I know the drivers will lower my overall gear ratio, but what will that do to how the clutch works??
Thanks in advance.

I don't think 36 round slides will be enough. Do not use powerjets. Ideally 94-96 vmax 600 flatslides work the best. They fit great and the jetting is very close as they come off the vmax, mains and pilots just have to come down a little. 47.5 pilots are close, 145-147.5 ish on the mains.

Unless you are running deep snow you will want to gear up a tooth on top on older Phazers. With a smaller driver you will need more than that.
do you have a pic of the skid in the snowmachine , i was about to put a 99 zr 600 skid in my venture this weekend and a used track , i live in nome alaska and its to hard to find parts for the stock one so i;m going to replace my skid out, also to gain a little travel ,
you must have really wedged that track in there, i couldnt get a 1.75 to clear with 7 tooth antiratchets. curious.
