New throttle body boot and good to go!

This is how I found it before taking it apart. About $20 from home depot for everything. I will never finish dressing an engine without pressure testing it again!

Here is a pic of the boot. I can't believe I didn't notice it. Held it up to the light, blew it off with air and shot it with WD 40 before putting it on and never saw the dent.

Parts are ordered and should be here Wednesday. Now I just need one more storm to break this thing in!

Well I figured it out. I am embarrassed to say that I didn't notice the throttle body boot had a good sized dent in it on the pto side. I checked the outside thoroughly but never looked at the inside. At least I didn't have to tear it down!

Got ya. I have always went a little over on the cases, and this time I didn't.

True. I was very thorough so it is disappointing. Do you guys torque to factory specs? I always thought they seemed light.

I agree Yamabond is great. But I need to blame someone so I am blaming him. LOL The thought of starting over makes me cringe!

I am just pissed as I thought I did everything right. Hell, when I was a "kid" I never used a torque wrench. Maybe that was why I didn't have issues as I over tightened everything. LOL

Unfortunately I think Rabbi was correct. I let it warm up to where it would idle down and run mainly on the mag side. Sprayed the front PTO seam with carb cleaner and the rpms jumped up. I REALLY wanted him to be wrong! I took my time with this build and thought i did everything right. I...

Thanks Rabbi, I forgot to put that on my list. Sprayed carb cleaner behind clutch area and no difference. EDIT - I am going to try spraying the case seam as well and see what happens. I hit the seal area pretty good and saw no difference. But, this sure does seem like vacuum leak. Does it...

This is not an Axys, but I this area gets much more traffic and I am hoping to get some answers for those smarter than me on the CFI system! This is a 2010 Rush with the 2+2 system. This is a fresh full rebuild, and I bought it with the PTO rod snapped in half and the case totally ruined. When...

div20 is the code for the thumbs up smilie. If you are looking on your phone it may show the code instead of the smilie. Div20

Got ya. It SHOULD go into slight overdrive. But I will let others comment, as I don't gear for overdrive. :)

I think he was saying to check/adjust the front track shock? Are you not happy with the top speed?

Yes and no. Gearing down CAN give you better acceleration. But there is a point where it won't. You can't compare gearing a vehicle with a fixed ratio transmission to a sled with a CVT

I agree. High belt speeds also come into play. Maximum efficiency is between 2:1 and 1:1, peaking at 1.5:1. IMO, I wouldn't gear to hit overdrive often.

How did these work? Looks like a much cheaper alternative to the Polaris fuel sock/filter.

I stumbled across this forum last week as I just got back into snowmobiling. I have been in the sport for about 20 years, and took a break a couple years ago when I sold my ProX440/600. I just picked up a 2010 Polaris Rush as a project/budget build and have been getting it back together...
