I am ready to seal up the cases with the rebuilt crank. Slow and steady, heavy on OEM parts this time. May post up a video series start to finish.

Perfect. I have the manual but didn't think to look for the spec there. Thank you. Took out the PTO rod in the fall - crankcase was dry compared to center/mag. Suspect seals or carbs. Rebuilt...

Keihin - yes. Only marking I can find are

So...not sure

Hey all - working on my '96 1050 during hard water season. Where's the best place to get OEM carburetor rebuild kits? Thanks!

I sent a reply to your message but it isn't showing in my sent folder

It is disappointing. I have rebuilt dozens of motors and this one is not cooperating. Interestingly I spoke to the previous owner and it he owned it most of its life only rebuilding it in 2004 (top...

Rebuilt the motor, switched to premix, and installed a great looking bank of carbs from a '97 donor. TOASTED the PTO rod due to lack of fuel/oil. My message to all - don't wait! Rebuild the carbs...

Great. Btw I have an extra set of cases if your looking.

My list would be:
>boots secured well on wires?
>wiring correct?
>grounds all good?
>possible defective? Try to run again with original

With good plug color it probably isn't a fuel issue. Thinking something along the lines of spark not advancing?? (Dont know how to figure that out). Another idea is that the driveline has bad...

Here is a link I have found useful to compare parts numbers. Sorry I don't know the answer off the top of my head

I found this helpful to look up and compare parts. I have noted between the 96 & 97 different head #s which translate to different compression...

Ride on! Keep me posted.

JP44 I am in the same position - I did a complete motor rebuild and took out the PTO piston after 4 hours. Only a couple guys usually reply and the responses are somewhat helpful.

2 stroke motors...

I will definitely do the single cylinder test to verify each cylinder is running. Any concerns using a 50 head on the PTO? The original 34 head is in really bad shape and I have readily available...

According to the Polaris shop manual there were 2 timing versions of the 105:

1) firing order 1/2/3 coil pack 4060138 (1240 ohms)
2) firing order 1/3/2 coil pack 4060153 (1550 ohms)- most common...

Reason for PTO burnt piston? From my pictures I sent my crankshaft in to be rebuild (firing order 1/3/2) the rebuilt crankshaft is now (firing order 1/2/3). To get it to run I swapped blk/blue and...

I also verified that the crankshaft is phased 120 degrees apart in the order of mag / center / pto when turning counterclockwise (looking at the back of the motor). So the firing order is 1/2/3. I...

Okay - I was a little mixed up due to the donor motor and my list of parts off that.

My '96 that has the bad PTO piston has all 034 heads on it. The one on the PTO side is really bad and since...

Confused- it idles fine but then doesn't?

Do you have a really good battery? Below 10.6 volts no spark. Near that spotty. Caused me a ton of issues and should have listened to the guys on the forum - battery is super important.

34 PTO, 25 center, 50 mag

Noticed today the head on the PTO cylinder is labeled 3022034. Any problems running this head versus a 25 or 50?

Will check for air leaks and pull that carb apart to verify everything. Can't seem to locate and posts on crankshaft phasing...
