thanks Lenny that was what we was wondering let us know how they work thanks for in put. dedub

I may just let the guys at the Jamboree tell you what they think. I'll let them drive it if they would like. My first impression is they work real good, lots of extra torque.

To get the valve lash information I need to give to silverbullet What do I need to do. I think I need to rotate the cam were the lobe is up then take a feeler gauge and measure under the cam and lifter is this right and what should it measure.

Yes that is correct. There is a hex at the center of the exhaust cam that you can rotate it by. Just be careful and remove the spark plugs and be sure to have it in neutral. You will be basicly turning the engine using the timing belt so take it slow and easy. The valve lash is a bit difficult to measure on the front 2 valves but you can do it. I took my feeler gauge and bent the last aprox. 1" length of it to about 45 degrees to make it easier to get into the clearance between the lobes low point and the shim that sets into the pocket in the little cup. This measurment is important you get it correct. The best way to be confident that you have it measured right is to take 2 measurments on each valve. It may take several trys to get these 2 values but it's not too bad. What you want is the "go" and the "no go" measurments. These should be .001" apart. The one that goes should slide under freely or with very little resistance. You may feel it lightly tight but not much a all. The one that is a "no go" should be .001" larger then the "go" gauge blade but not want to slide under at all. SilverBullet will want to see both dimensions for each of the 16 valves, thus 32 values. The new cams are a specific dimension different then the stock cams. SilverBullet, by providing secondary shims that will be placed under the stock shims will bring the valve lash clearance to the correct measurment range as specified by SilverBullet. By receiving your correct current valve lash info, he can see to it that even if your current lash clearance is incorrect, that you receive secondary shims that will bring you to the correct clearance range. Be sure to carefully mark which measurment goes with which valve otherwise this won't work correctly. If SilverBullet doesn't provide you with a drawing of the top of the engine head with valve numbering information, do your own drawing. Always remember that the front of the engine is always the end with the accessories, like alternator etc. On the Trooper that makes the nuimber one cylinder being at the rear side of the Trooper and number 4 cylinder being right behind the seats. Silver bullet will tell you what clearance dimensions are correct. I'm not going to tell you here so you don't get influnenced by what you think you should be seeing. What Rick wants is what you are measuring for sure and nothing else. Just take your time.

Kinarfi, could you please add this to tech articles for others to refer to? Thank you.

Silverbullet.

I will have a better idear next week when we take ours apart.This is not a job you want to rush.Read the instruction and go step by step.

Thank you for responding. I really am interested. Even tho I can do the work, it means something else will not get done. My plate is already full.

How hard and how long would it take to install silverbullet new cams

It will take you all day.Just read instructions.Go slow step 1 and 2-3-4

We are taking apart our trooper so we can give you step by step with pictures and text.We will try to make it as easy as possible.We will try to give you every thing you need.V/C gasket toque specs.If you need timing belt we will have it.Just go slow you should due compression test and check valve clearances so you will no spec.If vary tight then some thing is going on like valves may be worn out.If compression is about 140 on all cylinders and you have clearance you should be ok.

Compression is about even on all cylinder thats a good sign.

This is just my thoughs on how to proceed with this job.The more experance the faster it will go.Retoque cylinder head bolts

If you need tech help call us

928 344 2117.It not hard just adjusting valve clearance is a pain.We will try to make it as easy as possibly.

I don't know if you have shims, but you should put together a shim kit that has 16 of every size available, then when someone does a cam or a valve job or just needs to do a tune up, they rent your shim kit and when they return it with there used shims, you return a portion of the rent according to how many of your shims they used.

Just a thought.

Getting ready for my cams install and air/fuel ratio gauge so I can ajust my fuel controller. What numbers should I be looking for 10.7 to 12.7 or what post-178-0-43496300-1310254986_thumb.jpg

Read your plugs. If you look in Google, You will find charts with pictures showing different plug conditions and what they mean. 10.7 may be a bit rich. I would shoot for maybe 11.5 when accelerating hard and about 12.5 when you back off a bit. If your just crusing it should be more 14 to 15 with 14.7 being a complete burn ratio. Best power will be around 11-12 area. Like i say watch your plugs. If you run too rich you stand a chance of burning your valves even though you might get a bit extra power at low end buy being extra rich.

      Put a new carb on the 500 to replace the leaking OE one.  Machine idles fine and mid and top end runs great.  It tends to have a hesitation right from the start - bottom end.   Thinking it may be the air/fuel screw??  I didn't do anything with the carb out of the box and is it direct replacement for my machine.  Of interest is the manual choke doesn't seem to work very good now.... wonder is it getting too much air?
       
      Any help appreciated!

      Okay folks. I have a low power issue. Been like this for a few years. Place I work at bought 3 and all have lost most of the pulling power.  They gave them away after local shop worked on one for 3 months and it had great power for about 1 month and then crap. They replaced throttle body, fuel injector, spark plug and IAC motor. Seat belt switches have wires cut and left open so no seat belt warning light anymore. It revs to 6k rpm in neutral but when put in gear and take off in low it just doesn’t seem to want to go anymore. Running 93 octane fuel with Stabil.  Any ideas greatly appreciated. I dont have a scan tool but no codes on dash. If held to floor it pops a little and runs almost 5K rpm but if I let off pedal about an inch it smoothed out and revs up to 6k rpm.

      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL

      Just bought a Bad Boy Bandit 750. Need to change the oil and filter. Any suggestions would be greatly appreciated. I'm pretty sure this a Hisun 750 Sector even though it says it's a Bad Boy. I'll include pics soon.

      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...
