does anyone know if you can change the 265cc Subaru motor with a different engine? something with more power? if it is possible, where can you get one and would any modifications be needed?

The Harbor Freight Predator 420cc should work but verify your shaft size and rotation is the same. The Honda 390cc is a great engine but will cost a lot more.

Keep in mind that the factory matches the drive clutch and belt to the engine horsepower. Too much horsepower will smoke the belt and maybe the clutch.. your factory setup should be ok with a modest upgrade. I think your drive setup can handle up to a 400cca and would not go more than 420cc unless you plant to  upgrade clutches and belt .

      Identify this part help needed
      By Wolfpaak
      I think this part is causing a high idle problem(4000 rpm at start up) in my 04 R4 Joyner. I took it out and cleaned it and the problem went away. I just went out to start my SXS and it's idle jumped up to 4 grand again. Can someone tell me what this part is called so I can search for a new one. Or can you point me towards a source. 
      Thanks in advance.

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      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!

      Oil change
      By Joe Breaux
      Decided to do an oil change on the Massimo ...drained oil, screen was very clean even tho oil wasn't.  Then went to remove old filter.. holy crap ..I tried every tool I have, could not budge it..Went to store and got one of the end cap type..fit nice and tight, put a 1/2 in drive ratchet on it..nope..not moving.  Put a 18 on breaker bar o. It. The inside of the removal tool broke off!!  Had to weld it back together. Put a pipe on the bar for more leverage.  Finally broke it loose..
      I have never seen a filter in my 55 yrs of working on engines so tight..And i was the one who put it on 2 yrs ago.  JUST HAND TIGHT!

      Just bought a 2014 Volunteer. Can anyone tell me what parts have to come off to change the oil and filter. I can see them but I can't figure out how to access them. Thank You

      Hisun 700 engine
      By Duane Baker
      I'm looking for an engine for my Hisun 700 SXS.
      I've found a LOT of scam sites, and need to find a legitimate business to purchase a used engine.
