my 2005 3010 mule with the 620 in it decided it was tired and went to knocking. i have ordered the predator 670 v twin that should be here tomorrow for my replacement motor. as far as the clutch i am looking at the comet 780 for around 280.00. has any one ever did a motor change that might could give me any advice on the project or clutch.

thanks robbie

Predator's are pretty good, lasting engines. Most people i know dont swap engines,  but just rebuild it.

A lot of the times, Piston slap (knocking):  Piston slap occurs when the gap between piston and cylinder is too wide. Through wear and tear, the gap between piston and cylinder becomes wider. The noise associated with piston slap occurs in association with the perpendicular movement of the piston.

just a little lesson ;):)

      I use my Hisun 550 (with the Coleman stickers), for general work around my 10 acres of hilly land. Hauling firewood, some dirt and mulch, and debris clean up. Also felling dead standing trees in the woods and hauling rounds out to the barn for splitting/stacking.
      Here's my question:  Those who use their UTVs with towed drag implements or snow plows, have you noticed any issues with early clutch slippage or failures?  Or premature belt wear?  Other drive line issues??
      Thanks in advance for any experienced thoughts and comments.

      As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault!  I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

      Our R&D team just finished the first unit and wanted to show you guys. Need more cargo space without losing the functionality of being able to fold down the seat to use the full bed? Eagle Mountain Outfitters, the maker of the original metal UTV roof, has designed a foldable rear cargo basket to meet your needs. Price is $625 + $30 shipping.  If you have any question's, please reach out to me at [email protected]

      the regen braking on my e1 has stopped working unless (for eg) I am going down a hill in low and it's slowing things down to stick to the 10kph limit. when I drive and take my foot off the accelerator it's not initiating the regen to slow things down and instead just coasts at whatever speed it is at, or speeds up as the regen is not limiting it. the brake lights work, so it's probably not a fault with the sensor on the brake pedal
       
      hoping someone else might be able to provide some suggestions on things to check, as the mob that I bought it off seem to have gone silent on me

      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!
