Lenny, what you say is true concerning the tongue weight and I have seen the result of not getting it right. About 20 years ago I did a bit of competition rally driving with a mate of mine who had a very fast Mk1 Escort (English Ford Escort) but was a hopeless driver. He was always crashing and on this occasion we rolled about four times and landed on our feet again. Anyway to cut the drama short we winched the car on the trailer and started tying it down when I noticed the thing was to much on one side and not far enough forward. My mate was that p***** off he wouldn't listen to me and said he would leave it like that and just go the 90k/m (50 miles) trip back slowly. As I had my wife with me I refused to go back with him and told him he would roll it going down the Bombay Hill heading in to Auckland and that's just what happened. He destroyed the towing vehicle, the rally car and the trailer but my mate and his wife were uninjured with just his pride dented. We saw the whole thing unfold from a car right behind him and in the 10 seconds or so it took from when he lost control he had several near misses that would of ended badly for sure.

Always make sure you get the balance right and with just the right amount of weight on the toe-ball it should behave just how Lenny described above.

Cheers Mike.

the last thing i did was change to 400 over 600 on the back, made a big difference for the good. The sway bar i am against for 2 reasons. one is you need to have independent wheel travel for what the trooper does best and that is climbing, the other thing is these cars do not need any more weight. Putting the 400s in back took away alot of the car wanting to slide and catch while turning fast. There has also been some talk on toe in or out, remember when you are turning the inside tire is always turning tighter. I have found that i like my car with a little toe out, it seems to make the front tires bite better while turning, i know car manufacters set there cars with toe in because it causes the cars to push in a turn, they do not like a car that the back will spin first. I have always set my toe by using two strait edges against the tires 6" up on the side wall.

I have a question for those shock gerus out there that know more then I do about the subject. Opps, thats almost everyone. I'm beginning to tune my fox shocks. Flatbed has pretty well guided me to my current point and it's really nice, but it does need tuning. He can't easily guide me through that part unless he could actually drive my Trooper. So I've got to learn some things myself.

I can change the dampening for compression and rebound but I can't change the high speed compression, for example, and the low speed compression differently on the same shock. At least not that I know of. What I want to know, is, can I acheive this result buy changing the oil weight? And, if so, how?

Thanks for all the help everybody has given already.

Flatbed will correct me if I am wrong but the new shocks performance is changed by changing the valving, not the oil. Old school we changed the oil but this new shock is all in the valving!

use the same shock oil, it is all in the valving, changing the oil changes every function of the shock, by changing valving you can change rate on just one part of the shock.

      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...

      Riding out today it acted like it ran out of gas,  stalled and died and would not start.   Towed back to house,  New  plug added this past month,  plenty of oil, getting plenty of gas, battery cranks good.   Trys to kick in and starts but doesnt.   Two days prior while sitting at a idle it died.  Added gas and it started did my ranch chores with it.  But just now it stalled out cranks but will not start.   Tried to find if fault codes came up on the clock like manual says but not sure I am doing that right.  Any and all help apprecated.  Thank you

      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

      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

      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!
