The ATV Motocross National Championship (ATVMX) presented by CST Tires, an AMA National Championship, came to an end for the 2018 season this weekend, August 11-12, in Hurricane Mills Tennessee at the historic Loretta Lynn Ranch. Only 10 points separated the top two riders in the AMA Pro ATV standings – Rockford Fosgate/Ti-Lube/Honda’s Joel Hetrick and Wienen Motorsports/Yamaha/Maxxis’ Chad Wienen – after their season-long battle came all the way down to the final moto of the year.

Tube valve stem type

Hi
First time posting...


I've searched what I think are the correct forums for over an hour looking for an answer, but have come up empty.


I have a 2008 Outlander Max 650. Today I put a hole in the sidewall of my rear tire (tire found a partial power saw file) ..... I patched it but am not confident that it'll hold so I'm looking to put a tube to ensure no leaks.


Tire size 26 x 10 x 12


Does anyone know what type of valve stem is required?
It'll be either a TR6 (straight stem) or a JS2 (right angled stem) or ..........?


And, if anyone has a link to an online retailer with the appropriate tube noted, I'd appreciate the response.
I live in the boondocks so mail order or UPS/FedEx is my only option.


Thanks in advance for any thoughts/comments anyone has to offer.


Cheers, Chuck

Hello,
This is my first time one here. I am working on my 06 Polaris sportsman 500. At first I had several codes pull up, I traced down the main problem to the ECM. I replaced the ECM and all codes went away except 56, fuel pump short to ground, ect. Where I am confused at is now I have a code 74. I have checked several times just to make sure thats what it is. I have no I deal what a code 74 is. someone please help. Thank you.

Battery not charging

So I didn’t know anything was wrong until well it quit. Luckily I was with a group and I got a tow home. Just before it stopped it displayed “Lo”. Once home I measured battery voltage to be 10.6v. I’m guessing that’s what that Lo message was all about. Tested the Stator output. That checked out OK. Only thing left is the Rectifier/Regulator magic box. And it seems there is no way to test this magic box other than plug it in and see if it works. That’s all fine I’ll replace that magic box and all should be back to normal. What rots my socks about this is there is no fore warning to a looming engine failure. The “Lo” message was too little to late. Something like the alternator light in a car would be nice. Has anybody put such a light together.
