Ive searched and cannot find any performance parts that fit my machine.

I have a 2020 coleman ut400.

Im looking for machined sheave kit, programmers, cdi, exhaust and intake.

I know these are yamaha rhino clones but are they rhino 450 clones?

 

Any info is appreciated.

JMHO, but I think you bought the wrong machine if you are looking to hop something up. Whatever you could do wouldn’t overcome the fact that you have a single speed un changeable gearing in a 1100 lb platform powered by a little “400” engine. Most owners focus on noise reduction and trying to make it more comfortable.

I got the machine basically for free with a blown engine. I rebuilt the engine, replaced crank, cylinder, piston and timing chain. It runs good and has a top speed of alittle over 40. It seems to me that the engine is a clone of a kodiak 450 efi, so i figured parts for them should work. I know it will never be fast being a 400 but wanted to get alittle more pulling power out of it.

Let us know if you find parts that fit. I believe it's a rhino 450 clone, but not sure if engine parts are swappable,, AND I've yet to read any definitive reports of anything swappable.

The engine tune is adjustable via HUD ECU hacker software, which is free. Just need about $25 in cabling and the time and knowledge to play with the fuel mapping.

Here's my explanation on how to get HUD ECU hacker working on these rigs and what you need

That having been said its a 400 so you wont likely squeeze much more out of the engine.

Good to hear. There are a few parts that seem to be problematic, like the timing chain, on these motors. I figured if I ever need to cross that bridge I would try and see if the Yamaha timing chain would fit as a more reliable replacement.

You may want to use your cell phone GPS app to clock your speed and compare it to the speedo in the UT400.  I did this and it's almost 10 mph off.  Speedo read 42 mph and the GPS was 33 mph.  I really don't think they're very accurate.

I know I am late to the party but, am I wrong to assume the pursuit for more power was fruitless? I have been fighting mine for a while. It runs now but will lose power and die. Then will restart without issue. I am waiting on my second plug wire as this latest one has cracks and will arc to the frame or motor. If this does not do the trick I think I may just replace the coil as it acts like my old Ford did when the coil was failing. I do wish there were upgrades for more reliable operation. Short of a turbo or NOX I doubt more power is capable. I am sure someone out there has dropped a whole new power plant in to one but I have not seen that yet lol

      Looking for a output shaft for a Joyner trooper t2. Went to move the buggy after sitting all winter and it appears the out put shaft that drives the rear wheels broke off inside the transmission so looking for the shaft or a complete transmission if someone has one

      working on a coleman 550 out fitter , had a shit load of codes, coil, injector , and the map sensor for fuel injector replaced all 3 and figured it would start , but no joy have spark (new plug also and inline fuel filter) cleared the codes and still have the engine light , turns over fine but damn thing still will not start, friends daughters were driving it and turned it off to park , and went back to start it and same thing turns over but will not start , with this machine anyone have any ideas as to what the hell , I should be looking for , no plug's unplug checked wires none seem to be pulled apart or broken !

      I have a 2020 800 sx with about 16 hours on it.  From day one I have heard a clunking noise from the front end going over bumps.  Has anyone else experienced this?  Also this past weekend while out riding I heard a noise that sounded like the dump bed bounced three or four different times, again has anyone experienced anything like that.  Thanks, gary

      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!
