Sheave service update

Update on my sheave maintenance:

I service the sheaves last weekend, (2,500 miles since I installed the JBS greaseless sheave).

will try to post pictures

The air duct that feeds to the top of the sheave housing had big hole because it was melted. I repaired it with an aluminum air duct for fire place and wrapped it with aluminum wrap. I am assuming the dust in the sheave got there through this hole.

The primary sheave was relatively clean; there was   couple of cups of silt in it. I cleaned it all up, replaced all seals and greased it (based on James’s video).

The secondary sheave was also in a good shape, cleaned it up and replaced all of the O-rings and seals.

While I had the rhino tore apart I did:

Valve adjustment, replaced all fluids, and cleaned the K&N, new plug, etc.

Also, I did the crank breather mod (followed James’s process)

Questions/problems:

1-     Why would the heat ( I am assuming from the exhaust header) melt a hole in the snorkel)?

2-     I have the Dynatek module installed; the bike starts and runs well but kind of struggles to reach the top speed.

3-     I pulled the plug after 100 mile run and it was covered with black soot, so the bike is running rich.

4-     I started to muck around with the dials on the programmable Daynatk module, no major change.

5-     I have not removed the module to see if the bike runs better.

6-     Would a defective “air temp sensor” cause the bike run rich?

7-     Any ideas – either I am getting too much fuel or not getting enough air

Thanks

I talked to James yesterday, I am going to change the ignition coil with the Dynatek unit and also replace the air temp. sensor. Hopefuly these 2 items will take care of the rich running condition.
I repaired and wrapped the snorkle with alot of Alum. tape.
Thanks

you should send that dynatek in and have them check it

Update:
It is running like a champ!
I got the coil from James and installed it today. I installed the Iridium plug (CPR7EAIX-9) and did Couple of test runs and the spark plug is nice and tan colored. No hesitation or stumble. So my guess is the stock coil was weak.
It comfortably goes up to 48MPH, 52 or so going down incline. Probably will go a lot faster if I did not have full windshield on the front, full Tusk shield behind the seat, and another full shield behind the roll cage.
Thank you all for your help.
Special thanks to James and Nikki for getting my parts to me fast

what kind of doors are those?

Yes this is near the Rim road, South of HWY 260 in Overgaard. I have a summer home in Overgaard where I keep the Rhino at. There are hundreds of miles great forest service trails, perfect year round riding. Fun in the snow in a month or so.

The doors are J Strong. Work much better than the stock doors keeping the mud out.
