30 mm clutch vs 33 mm clutch

The center seals on my 03 Mountain Cat 900 started leaking, I found a crank on ebay for $300 and after I got it put in I found out the crank from ebay has a 30 mm shaft. My old crank had a 33 mm shaft. My question is, can I just put a 30 mm primary on and go? The 33 mm shaft has a lot longer mating surface for the primary, I was wondering if this was to accommodate the extra torque from the 900 vs the 800 that the 30 mm crank came from.

XLT Indy 500 idle too high

I have a pretty lightly used (2800 miles) original engine 1995 Polaris Indy 500 XLT 500 triple. I had no problems with it up until last year. It began to be really difficult to start and would not idle. So I first attempted to adjust the carbs with no good results, then dismantled them for cleaning and inspection. I that two of the choke plungers were stuck in place which would explain the hard starting and stalling at idle. It would run fine when up to speed.

So, I installed a new choke cable, cleaned the choke passages, carbs and jets. Problem solved right? Well, it did solve the stalling at idle and difficulty starting. Now the problem I have is that it won't idle below 4k...meaning it's like it's stuck in that position. I have read that bad crank seals could be one possible cause. I don't think that is it because the problem began right after I had worked on it and the plugs are not showing a lean condition at all. I did notice that the throttle cable is stretched and I have slop at the throttle cable. I ordered a new throttle cable and am waiting for it to arrive. I also have the carb idle adjustments at their lowest setting and it didn't help. I drained the tank, put in new fuel and have cleaned the carbs twice. This is a very frustrating problem, help is appreciated!

Skiis on 2009 F8 Sno Pro

Hi AC sledders, I'm in the market for upgrading my sled. I have an RX1 and looking at the 2009 F8 Sno Pro. Everything I read about the F8 it sounds like the sled for me. Aggressive trail rider. In my research it does say the 2010 is a better model to get than the 2009(my price range). True? I can't find any 2010 near me. I here the skiis are a major difference on the 10' from the 09'. Can someone tell me if its possible to put the 2010 skiis on that 09' sled? As you can tell I'm new to sledding so excuse the ignorance. Appreciate any feedback.

Synchronizing carbs 88 Phazer

Reading in my Clymer service manual, it tells me to remove the crossover pipe between the carbs in order to synchronize the carbs.

But it doesn't mention putting something in its place, otherwise there are two big holes in the intake to suck air.

I wish the service manual would be more clear about this.

So, my question is this: When synching the carbs, do you block off the crossover pipe inlets? If so, what do you use?

One other quick question: What is wrong with the pistons? I see that people often ask about the pistons or have replaced them? Why? Is there a defect?

New to this

Hello everyone..... I am looking to get into snowmobile... I am looking at trail riding in NH. It would be me and maybe one other adult so I am looking at a 2-up. I figured I would start slow and buy used and see how much I like it. Can anyone give me feedback on a 2000 skidoo 440 2 up es & rev. I know nothing about engine size 440?? I am big guy 290lbs 6,2 (not sure if that even matters) but anyway they are look to get $1300.00 for the machine it also has 5000 miles on it. Anyway any feedback would be great.

1996 xcr sp 600 build/questions

Not sure if this is the correct section to post under, just looking to post updates and ask questions along the way. I recently picked up one of the despised 1996 xcr sp 600s for 600 bucks for something to tinker with and try to make trail worthy. Only 2800 miles and 125 psi in all cylinders, really clean sled. Like every other one this sled is a dog off the line then screams on top end. So far I have installed 350 350 and 330 mains, needle on 3rd clip, 40 pilots, and drilled out pilot bypass and air screw .5 turns out. It was running crazy rich prior. I have purchased epi black spring for the primary and red for the secondary (I hope this is equivalent to the olp hsp white secondary if anyone could verify that would be awesome), hot seat z weights and 38 helix are on the way. Currently has stock gearing 21/35. First question I have read to switch to a 39 tooth on the bottom, can I install this without having to monkey with the chain? Second if someone could explain to me how to set belt sheave clearance that would be much appreciated as well.


Thanks, Josh
