I purchased a 2008 American Sportsworks Subaru TW265 UTV, with no manual and no previous knowledge. When idling, the steer column shakes uncontrollably, is very noisy, and might be from vibrations from the engine. Logically, I am thinking engine vibration moving up the steering column. I found a schematic, but that has not helped in identifying the specific problem.
Any thoughts? Suggestions?
Thanks so much

starts up you have keep rpms up for 5 minutes till it warms up then runs fine. But if it stalls wont start unless you unplug fuel pump and hold it to the floor till it starts then plug pump back in and run it till it warms up then it is fine all day.

Have a Coleman UTV 400 that cranks, runs, drives well until it gets warm and is put under load. Light throttle or full throttle it doesn't bog, but it will cut out mid throttle if you move the pedal quicker than it seems to like for example when you're getting ready to go up a hill, but if you immediately floor it, it will do just fine and not cut out. It's random if and when it's going to do it, but is consistent in that it happens only when hot/full operating temperature. I've replaced the injector twice, same with the spark plug and tried different heat ranges (NGK 7,8 and 8 iridium), replaced the fuel pump, adjusted the valves, checked air filter which is like new, changed the oil, replaced the fuel filter. No check engine light. I don't have a code reader for this. Initially I thought it might have a head or head gasket issue as when I got it, the oil was over full, very runny like water milky and it was smoking. I've changed the oil since then twice to clear and clean everything out, and it seems to be good. Coolant stays the same level and so does oil with no changes in consistency or need for adding more. Had I think 7-9 miles when I got it and now has about 77. What should I try or consider next?

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.

Hi,
New to the forum.
Came here looking for some experienced UTV users who can enlighten me about which brand should I pick for my very first UTV or SXS.
I'm between 3 brands and 3 models:
*Kawasaki MULE PRO-FXR 1000.
*Yamaha wolverine rmax2.
*Can am Commander XTP.
The use I'm willing to give it is mostly to go to the range with my wife, load steel targets and all our shooting gear, we shoot a lot, rifles, Shotguns and Handguns for practice, training and competition. (Range is about 10 miles from home)
But also I want something that I can take to the trails and have fun on dirt, mud, rocks, puddles or creeks.
Any objective information will be appreciated, specially which is more reliable and durable.
Thank you and happy 4th of July.
