Kubota UTV RTV Forum

There was another kit to do this that uses conventional valve stems, it comes with a tube a rod that you screw the valve stem into and a hook to extract the valve stem so its not rolling around in your tire. Use the hook to extract the old valve stem, line up the tube with the hole, screw valve stem to the rod and push it through the tube, when it goes in the hole pull back until it pops in place. I havent used this one sounded like a lot of messing around, but may work fine and would be more economical if you had very many to do.

No problem at all. Depending on what size winch you get, larger uses more battery power, but its not on all the time so battery gets charged back up after you use it. I would probably go for a small one 2500 or 3500, Timberwolfe is not that heavy.

I have a Yamaha Timberwolf 4x4 250. I want to put a winch on it, but just wondering if the charging system will handle it or not ? Has anyone added one to their machine and have you had any issues?

CDI is probably not the issue, i would check for correct resistance at the main coil and also pickup coil, which is attached to the stator. Also check to make sure you have a good ground at the main coil and CDI . You can also check to see if the pickup coil is putting out voltage, i usually do it with an anologue meter with a needle seems to be more sensitive to small voltage spikes, you can see the needle move , you have to look close or you will miss it, very quick.

A new thread makes it easier to follow.... Does it backfire ? Is it out of the carb or the exhaust ? Are you certain it's the mid range that's causing it, or could it perhaps be that it's when the load starts coming onto the engine that it starts to misfire ? In which case it's more likely to be a coil or lead, cap or sparkplug. The way to check if it's throttle position, or engine load, is to go up and then down a slope/hill. Start a new thread though.. Otherwise it's too easy to confuse bikes or owners or problems..

Very cool. I've never heard of them.

Have you ever been on the trail and your tire valve goes bad. No way to break down the wheel and replace it. A lot of you probably know about this already i had heard of it but never used one. Just punch out the old one insert and tighten down the nut So far it has worked very well.

Same exact issues with 02 yamaha big bear. Replaced with new carb. Same issue, bogging down when throttled past mid range. Bought another new carb, replaced again. Same issue. Good gas, jets all correct, screens clean, fuel lines clean, good gas, new battery, new plug, filters etc…Not sure about the CDI, but how about replacing the stator?Thoughts?

Most machinery, whatever it is, always wears the same parts out, which is why it doesn't always work out so good keeping old machines for spares... I think I'd choose the best rolling chassis with reasonable suspension brakes etc, and swap motors, bodywork etc onto that one. Just a guess without knowing if things are worn or crashed or blown up, but based on having seen(and done) a bit of this work.

Hi and welcome along. That does sound like a fun project.
