I remember that fork top-out clunk. It went away immediately after the revalve and never came back. I even forgot about it, until you brought it up, LOL. Regardless of what your stock front springs are, you can upgrade to the MX spring specs, and you should be much better when trail riding...

For the first five minutes -- yes. When you will be going 5-10mph over the limit and start seeing cars on your rear wheel, passing you on both sides, you will quickly realize that your speedometer is wrong. Then you will start adding 15-20mph to its reading, or whatever is necessary to not get...

The non-O-ring chains are best left to road racers. For dirt, I do not think a non-O-ring chain offers any reduction in friction after it gets packed with sand.

There is also a problem with either the torsion spring shape or the location of the hole on the frame. I chose to bend the spring. @Mark911 drilled a new hole. Both methods reduce the rubbing of the spring against the pedal.

I am setting up my van to charge from both 110V and 240V. I will have both types of plugs inside as well.

Hi Morten, I've heard a rumor somewhere that Alta wants to start selling the MXRs in Europe soon. How soon I do not know. The road legal bikes will take longer because of various homologation requirements, and may not happen at all without the ABS, but selling the off-road only version should...

These batteries are promising a smaller size, weight, cost, and a longer life. They just do not have a built-in BMS (Battery Management System). https://www.amazon.com/dp/B078JB836N/?tag=sce0f-20

Some questions still remain: 1) Do I need the stock lead battery at all? Should I replace it with Lithium? -- Yes, it is needed for starting. LiFePO4 batteries are not designed for engine starting loads. 2) If I have to keep the stock lead battery, then do I need a "battery isolator"? --...

So... I had Recipe #1, then Recipe #2, and now I have one more recipe: RECIPE #3 1) Buy a 12 - 110/240V inverter+charger: 4000 Watt Pure Sine Inverter Charger - 12 Vdc to 120/240 Vac (DONE!) 2) Buy 3x 100 Ah Lithium batteries: https://www.amazon.com/dp/B06XX197GJ/?tag=sce0f-20 Total...

I am curious to know the answer to this.

The MX/MXR/EXR chains are 116-link chains and 12/53 sprockets. I think the EX also uses 116 links, even though it uses a 13-tooth front sprocket. You can also run 118-link chains with the stock sprockets. This will move the rear wheel 5/8" back. I'd also recommend a 118-link chain if you are...

I have been buying Primary Drive chains from RMATVMC. They are well-priced X-ring chains. Very quiet and so far have lasted very well. The stock Alta's chain is junky, starts stretching after just 2-3 hours of riding and never stops. I replaced mine before it stretches too long and starts...

This is a pretty geeky discussion, I like it. It belongs into the Technical forum. I just moved it.

Bikes displaying an incorrect 10% higher speed seems to be a standard industry practice. No idea why motorcycle manufacturers keep doing this. A higher displayed value encourages speeding, shortens the warranty period, and hurts the resale value. Time to write to your congressman to request...

Awesome! Beautiful scenery, a great place to share with someone special in your life. Love it!

Man, glad you finally got yourself an Alta bike! I told you you'd like it! Thank you for the review and the video! (y)

LOL! This is awesome. They should add some more regen, chain, and dirt hitting the rear fender sounds though. But it is pretty close already, I like it. I think this video game had 60-70hp Altas though. I wonder how soon the MXR-R will be coming out. :D

Nice jungle riding!

I have stickied this thread. Hope it does not grow too big. But if we keep seeing certain error codes we will hopefully know what they mean and what to do about them.

Thank you for updating us. Please let us know how it works out.
