Plumber, can we get an update on the Cams? Hows it going? Smooth install? Is it tuned in? Torque increase?

Can't wait for some feedback on a stock motor!

I will know more tomorrow I talk to the mechanic tomorrow on when he is going to installing them. I was going to install them but I'm just like rocmoc to many thing going on right now.

Are you also advancing your cam timing by using an altered upper belt pully?

I was thinking about the question about changing the cam timing, would it be of any value to be able to change the cam timing while the engine is running and have the timing controlled by the computer, so the the timing can be changed for low speed and changed again for high speed? I think it would be doable.

Can't change the cam timing as it is all mechanical. There is thing that you could do to change it by manipulating the timing belt but very complicated to set up. You would have a longer belt to create some slack. That slack would then be taken up on one side or the other of the top pully, rotating the pully advancing or retarding it some. To messy to do.

I was thinking a linear actuator on the side going to the cam pulley and a spring loaded take up on the other and depending on what you need, the actuator pushes on the belt and backs off to advance or vise versa. That wouldn't be so tough would it? The linear actuator could be driven by a stepper motor.

Your idea is ok but there isn't any room under the cover.

ok plumber what a bout the cams ? dedub.

Well this is what happen and why I have not gave a cam update. I hire a mechanic with 40 years experience that I know for 30 years to do the job and it went wrong everybody I talk to says he didn't have it in time right and when he turn the key it bent six valves. So I had to have the head redone we have all that done but when it bend my valves it also broke and cracked some of my shimes so I had to fine some new shims. With the new cams the shims are not thick enough so you have to put a shim under a shim. But i found a shim thick enough so you don't have to put a shim under a shim I order them today so this is were I'm at

Sorry to hear that. This is why I am putting it off for a while. I'd hate to lose use of my Trooper through the summer. Hopefully the upgrade in torque will erase the bad memory. I just hope you remember what your Trooper used to feel like.

IT'S ALIVE, Well first of all let me give many thanks to Silverbullet if we had more business like him joyner would be a better product. Thats why I will buy all my stuff from Silverbullet he's the man when it comes to joyner parts again many thanks Rick I guess thats enought ass kissing LOL. Ok about the cam's when I started my engine it blew up just kidding. IT sounds awesome just like a car with a cam in it you can hear it the same thing here my wife said it sound like a crotch rocket .I have not took it out any were yet just across the street in a field will be going riding this weekend.But you can feel it in 2nd and 3rd real nice there is a short straight section that I get on it and it pick up about 5 more mph in it.Will write more this weekend after taking it out.

Great news! When the cams became a development item the desire was for more low-end torque. This does not necessarily transfer into more speed. We need a slow hill/rock climbing test report. For us slow go pull hard types, find a hill you use to climb and see if there is any improvement in torque at a slow speed. Would help with my decision.

Thanks,

rocmoc n AZ

Mine will idle smooth with the cam but I have an after market computer and I was able to tune out any looping at idle. Looping at idle is a good thing when it comes to sound. Glad to hear it Plumber. Welcome back to the living.

How'd dem cams do?

Great this should have been the way the trooper should of came out from the factory with. I think it runs cooler now to it never went over 180 I think they have these engines running to lean to past all the EPA stuff.I'm very happy with them I'm still ajusting my fuel controller to dail it in. If I had to do it all over again I would have just took the head off and send it to silverbullet to start with It made it real easy doing it that way. I also put a muffler on it my radiator fan is louder now than the tropper is and I put that expanded metal over the back to let some of the heat out of the engine compartment. Now I'm putting new gauges on it too

      Can-Am Ryker Accessories Question
      By hetovi
      Hello everyone.
      I recently bought a Can-Am Ryker and I'm looking to customize it with some accessories. I’ve seen a lot of options out there but wanted to get some recommendations from fellow riders.
      What are the must-have accessories for comfort, style, or performance?
      Specifically, I'm considering a windshield and better footpegs—are these worth the investment?
      Also, any thoughts on storage solutions like saddlebags or rear cases?
      Would love to hear your personal experiences with any mods you’ve done.

      2012 Axis 500 4x4, no power going up hill
      By Fishing Wiskers
      Top speed is 30mph on flat grass ground.  but it will not go up minor hills forward or reverse without a runing start.  If you start at the bottom of the hill machine will stop about 1/2 way up.  I have the engine cover off and you can see the outside of the drive clutch will stop spining., and the engine does bogg down some.  Dosent matter if engine is cold or warmed up.  Seat belts are connected.  Fuel is clean
      I am the 5th shop to look at it and different shops have replaced the fuel pump, injector, ign coil, wet clutch, 
      I am not sure how to check for codes with this machine,  can anyone teall me how to do it?
       
      Compression with hot eng is 145,  valves adjusted to .005 with a cold engine.  Dash shows 426 hours
      I am not convinced it's an engine problem

      still going
      By Joe Breaux
      just an update on my MSU 500 . For all the misery it caused me the first 2 yrs, and the combination of some quality YAMAHA parts, it has now become a reliable ,useful UTV without the constant fear of having to push or tow it back from trails. I have not had a single issue pop up in a very long time.. FINALLY!....and as a side note, I just bought  a C FORCE 600 ATV to replace an old and well used  Honda that finally after 18 yrs gave up a rod bearing.  So far the new one has really impressed me .. I like the new Power Steering and  this CVT Auto Trans is new to me on an ATV .. I m used to constant shifting on my Hondas .  It also has something I have never seen. Its EBS  engine brake system, as soon as you let go of throttle, it engine brakes you to a stop rather quickly.. its great idea for the grandkids safety . Takes a little getting used to tho.. All in all, I like it. We shall see how durable it is after break-in.. I do "RIDE" them! .....and they honor their warrenty! and the dealer is 15 minutes away..

      Help identifying some disconnected components on a Yard Sport YS400
      By BernieG
      I could really use some help identifying some disconnected components on a Yard Sport YS400. The first part is this pipe, which comes out of the exhaust port area or the cylinder. It looks like it had a piece of rubber hose on it, but the hose is gone, and I have no idea what it was previously connected to.

      The second item is this vacuum valve looking thing.  Again only one line is still attached.  What is it's function and what other lines should be connected to it?

      The last thing is this hose, which exits the side top of the fuel tank (not the fuel line hose) but is not connected to anything

       
      Any help the community could provide would be greatly appreciated.  This UTV belongs to a friend, and I am trying to help him get it running correctly for his kids.

      Honda or can am.
      By Jhud
      In the market for side by side. Narrowed it down between the pioneer 1000 or defender Hd9. Looking for pros and cons of both. Any info would be helpful in my selection process. Noise, speed, reliability, ride, all of it.
