Thanks, I was trying to save a couple of bucks, but in the long run it's costing more !
-
it truly boggles my one brain cell, trying to figure out why atv owners who ride an utility atv, want to '' get that one extra hp '' ?!..lol. you can only get so much from these machines, after that..its all over but the crying. soo..bottom line: don't bother trying to get 100 hp from an engine that is designed to give you 10 hp..lol.

oem all the way, stay far...far away from any after market parts, when you can get oem. if and when it comes time where we can't get oem anymore ?, then i will use china junk ( we won't have a choice ), until then, i will use oem all the way !. just ask jeep69 what he went through awhile back when he tried using a after market head gasket ?!!..lol.

01 Forman Rubicon 500, had coolant in oil, so I tore it down, the cam lobes where chewed up picked up a used one, cam chain was also garbage, water pump bearing was toast. So while in there I replaced the rings, got it all back together and runs good, except I forgot to check the head if it's warped! Needless to say coolant is seeping out on the lowest side of head when running. So what's a good head gasket? I used a after market one

Battery load test was good + full charge. Have not adjusted clutch. I ordered an O.E.M. angle sensor But will look up how to adjust clutch before installing sensor. Steve

Awesome, happy for you..yea, meltav helped me take the ECM plunge with the green coil wire to ground test, amazing to think NON OEM can wreck such havoc, here's to many trails and memories 😊 -

It is a rubber material and very flexible. About 3/16”. I wanted something thicker but the thicker mat that was in the store already was cracked as it was rolled up and would probably rip easily on the trail. I haven’t trail tested this hard yet so I will see how it holds up and report back after deer season starts in August.

thanks Jeep! I thought I had sent this message, but it was still sitting here waiting to be sent lol … Welcome to the forum! let me know your you’re making and model and I can most likely get you taken care of If you’d like to contact me, I’ll send my direct contact information to your message box -AKATV

Welcome aboard. Post up a pic of your meter on with the headlights on so we can see what you have. @AKATV will be along shortly.

Try without first. If it acts like it's running lean get a programmer. I did one on my wife's 09 DCT Rancher. I put a Weisco programmer on with the top end, but I honestly think it would have run fine without it. Didn't make much of a difference at all over the stock 420 cylinder. Not worth doing unless your original 420 cylinder is gone too far to be bored oversize again. I was curious as to the 520 top end, but you have to either turn down the outside of the bottom of the cylinder (Reduction Boss sells those ready to bolt on) or grind the cases a little to clear the bigger jug. I've gotten away from 420's and am sticking with the older machines, so never got around to the 520 swap.
-
Thanks guys! Got it fixed up.
-
Alright I'm gonna give it a try and see what she runs like. Hopefully alls well. I will send my scope down to check the piston just to see at some point
-
Ive done it with a kit from a Kentucky dealer. No issues with the machine after doing it. Fi model. Its really 475cc vs the 420.
-
I like the way they look. I need some too for a forman ,but don't want to pay the high price. I'll probably make some . Is that some type of rubber or plastic?
-
Like everyone else I have a meter that NLA. Meter works fine it is just sun faded and can barely see the digital information.

Melatv I think you’re correct by looking up that part. The model is TRX420FM1
-
Fair enough. I figured I'd put the bigger kit on there to see some possible gains and didn't think about it possibly running lean until now. I did some looking into ot some say it's the same but woth a different tuning others say it's different and will go lean.
-
i always use the correct top end parts. is there a reason you are not using the correct top end parts for the correct engine ?. can't answer your lean question ?, as i don't gamble on something i know nothing about..lol.
-
Hey guys about to do a 500 top end kit on a 2016 420. My question is will I need a fuel programmer or will it be fine without one and not run too lean? I've seen things online going both ways, it'll be fine without a programmer and it needs one or it'll run too lean. Any advice?

She’s all back together and I got the heat cycles done just need a chain FullSizeRender.MOV IMG_4134.MOV IMG_4138.MOV

Tires for the truck. The sipper may be down for the count, blowing oil out from somewhere. Yea I know what tire threads do to undies around here….. kinda why I wanna start one…..
-
Very true, that maybe a warning sign, but first it would be ignition fuse blowing .Went for short ride...wow, like a new machine, idles sweet, plenty of power, so happy, showing 3,250 miles in 14 years..thanks again guys.
