Most of us complain about the ridiculous noise in the cabin. My wife likes to ride but the noise is a major downer. You can’t even have a conversation without shouting at each other. Well, I manage to reduce the cabin noise by approx 200%!
I addressed the intake that is poorly placed right between the driver and passenger. First, I cut the air filter inlet pipe in half (pic 1). I then reinstalled it upside down (pic 2). I then attached a flexible intake tube (pic 3) and directed it behind the cabin (pic 4). Major difference.
Then I covered the interior engine cover with Dynamat extreme and then 200 mil Chaogang sound deadener / heat shield mat on top of that (pic 5). Since I cut off the intake and redirected it, I completely closed off the intake (engine fence) so no engine noise can come thru (pic 6). It also reduced the heat approx 50%. I did leave on the heat mat that came stock on the engine cover, so it has 3 different mats. It was a snug fit. Major difference again.
My wife rides all the time now since we can have a conversation when we ride. Major improvement to my riding experience. Thought you might like to check it out.

I'm working with a 2015 MSU-500. Basic symptoms are it cranks well, but will not fire. It has spark, and it has fuel spraying out of the injector (and spraying starting fluid into the throttle body and plug hole makes no difference). It has compression. I bought it not running, and no other information was available. It has 775 miles on it and 127 hours. It looks to be in very good shape. Previous owner replaced fuel pump, ECU, coil, plug, and the fuse/relay box that mounts on the firewall, then gave up.
My questions relate to cam/valve timing, considering the symptoms and diagnostics so far. My thinking was the woodruff key sheared off and the crank spun, making it out of time. My question is, by the pictures attached does anyone have an opinion as to the cam/valve timing being correct? In the crankshaft picture you can see a timing mark visible. In the camshaft picture I have arrows directed towards what I think are timing marks (which appear to be exactly 180 degrees from one another). However, the long arrow in what appears to be bolt configuration in line with the piston/rod line. Here is a puzzling note... in the position you see in the pictures... I have valve lash on both the intake and exhaust. I think it's at TDC, given the visible crank timing mark and valve lash on both valves.
Any thoughts ? Does this appear to be in proper valve time ? Have I missed anything simple ? Thanks in advance for your input.

Just received delivery of a 2024 AMP Pro. Thought I'd start a thread with my impressions as I use it and learn more. There doesn't seem to be a whole lot of real-world usage information out there on this model. Hope this will help others as they research.
Intended Use Cases
Fire mitigation / slash removal from a 5 acre forested and well-gamble-oaked property. The previous owners thought as much about fire mitigation as I do about fashion: not much. Snow removal Stump pulling General hauling (rock, lumber, etc.) Weimaraner energy depletion. Wasn't an original use case, but a nice added bonus. Experiences So Far
Wasn't impressed that two of the bumpers on the underside of the bed where it sits upon the frame were missing. The metal on metal contact has damaged the powder coating and the frame. I expect a little better QC.
I've only put a few hours on it, so not a ton to report on usage. It isn't quiet; it's silent. I can't even detect an electric note from the motor. I removed (and subsequently replaced) the motor cover noticed that the motor is German and made by Schambuller. The motor controller is Italian and made by Dana TM4. Given the operating specs of both I found on the web, I suspect both are higher quality than the previous Navitas (which is supposed to be decent). The motor is rated at 25 hp and 71.5 lb-ft of torque. It feels very powerful. All the torque is delivered instantly, if desired.
The bed is huge and has an electric dump as standard. Great feature but would like it to go up a bit more. Probably not feasible from an engineering perspective, but I want and I need ;).
Power steering is nice, but vague. Probably common to many UTVs, but I am accustomed to more direct results from input. Plan early and plan often.
In our first full day of usage, we hauled about 1/2 as much slash as the entire rest of the year when I was doing it by hand cart. I may get fatter, but I'll also get more done. After a few days of usage, the battery meter has gone down by 1/10th.
Until next time...

I want to ditch my Kubota RTV-XG850 and its moronic twitchy throttle design flaw, get rid of the problematic engine and the 40 mph purposely throttled speed.
So far, I'm looking at the Honda Pioneer 1000 and the Polaris Ranger 1000, both of which have 1000-1500 lb payload bed capacity.
What other makes and models should I be looking at?
Thanks for the help!

Hey guys. I was wondering if anyone pressure washes their Mule underbody. Three years in, I have yet to do this. I'm worried that the pressure washer could damage or dislodge something but it's gotten to the point that it could use a bath. Any thoughts?
