Philip, I check mine before each ride. Mainly because I used different air pressures for different tracks and temperature and altitude will affect the pressure. You want to bleed the pressure out with the bleed screws so you have a consistent fill each time out. I do have friends with air...

My friend was Scott Freeman and he was way ahead of these guys he put a electric motor in a 1990-91 Yamaha YZ250 frame. Work pretty good back then. I’ll have to see if I can get ahold of him.

I think they could make a flip up top with some padding on it for protection on the MXR.

Made these to keep the sun from baking on the display.

Mark911, Fod and Fog25 were out at LACR throwing dirt on the Gas bikes👍 Was nice meeting you Mark911 you were looking good on the track. Fod was riding great today also.👍 It was nice to have another Alta rider there to help with all the questions we were getting. I think we need to make up...

We are going to have to see which one, the Blue or Red torsion reducer is faster? I can see a lot of testing happening👍 Diverse Springs is the place to get your springs. 👍 http://www.diverse-mfg.com/

Tunable maps most likely wouldn’t happen. If Alta made them turntable for the general public most likely wouldn’t be much of a change from stock. They can’t have us Ya-hoos out there going to the extremes causing possible failure everyone would blame it on the bike and not the Ya-hoo. 1-...

Thanks. The next two pictures show the First Holeshot ⚡️ That was red flag due to Mike Marion going down we’re all concerned about his well-being and 🙏prayers being sent 🙏. Us old guys just don’t bounce good as we used to.

It was nice meeting you @wilhelm192 and thanks for your help and support on Saturday. Here’s a few more pictures of the weekend.

I used map 4 for the first three motors and in Moto four I switch on the third lap to map 3 in the back section and back to 4 on the hill and lap three was my fastest for the Moto.

It’s been a week If the marking department is not interested in promoting the bike I guess I’ve been wasting my time also. There was a lot of buzz over the MXR over Mammoth Vet weekend that went to waste it was the talk of the weekend. They missed out on a great opportunity to promote...

No only one slider broke, those two spots are where I think that needed reforcement so the new one will not break. So far holding up.

Up date on the slider modification. I came up with another spot for reforcement. I noticed the back corner end of the slider at the rear next to the bolt the chain was hitting it so I place another rubber bumper at the spot. That’s where mine broke. I need to clean it up a little I had to put it...

Mammoth MX report. Sign up for the inaugural 60 class at AMA Mammoth Motocross Championship. Haven’t race in two years but decided to try the Alta MXR in a race anyway. Mammoth Mx is a four Moto two day event at 7000ft altitude and the air is real thin and I figured the Alta would run good...

Here’s a video of my start at Mammoth MX. The very first start for the inaugural +60 class.

Learn one thing today at Mammoth MX you need to rejet a Harbor freight generator in higher altitude. Will not run on 240V for over three minutes.

I’ll have mine in the 60 class👍 For a real race experience 👍 wanted to know how the bike performs under actual race conditions. In the words of our great leader “Will see what happens” with the old body at 85%. If anybody up swing by and say hello.

Was changing tires today and notice there was dirt pack in around the spoke nipples under the band. Most likely came in around the gap in the rims at the nipples. Could be a problem in keeping the spokes torque. Some of the spokes were sticking out of the nipples (long) could cause a flat...

It’s a rubber foot from a speaker. I used a command strip on the top and bottom to hold it in place. I thought about using silicone but went with the command strip. I file a little angle to help with more mating surface. I figured it would support the gap in the middle and if it falls out I’ll...

Here’s my fix for the chains slider. I do not know if it will work yet till I go out riding?Will see how long it holds up?
