Rubicon Performance Upgrades

[brianwmcdonald]

What are you running for rubber? When i first had mine i was running 26" mudlites stock, could turn'em pretty good, but once i put on a pipe, k & n filter and re-jetted it woke it up pretty good. The clutch kit really brought it to life, and I'm putting a mudbuster cam in before spring just for a little more juice.

I'm running 26" mudlites as well. Can't turn them the way u describe. Bogs down unless in ES mode and in low gears. hard time starting after it sits for a couple of days too!!

I have 26 mudlights on mine and I don't seem to have a problem, I do however try to avoid mud holes if possible, especially the skeg ones. When I had these tires on my 450 I had no problems either, but we did rejet for altitude a few years later and I must say it had a lot more torque. I might rejet my Rubi if it starts giving me problems at altitude. Mine also has difficulty starting in winter after sitting. If it is too cold it won't start at all, even after using the primer, summer no issues at all with starting. My old 450 was way better at starting in cold.

After I had my Rubi rejeted it starts real easy no matter what temp, I've had it goin with no issues at -35, before I got it tuned though, you would just run the battery down, and after about a half hour or so it would start.

Where did you have the work done? And having never done this I have to ask the dumb question: are there different jet kits that you can look for?

 

[brianwmcdonald]

i took mine to accurate dyno in shearwood park, he'll get you what you need. there are a couple different types of jet kits out there, i went with the dyna-jet kit on mine.

Hope this helps,

Brian

Forgot to ask if fuel consumption was a noticeable change???

 

[brianwmcdonald]

Not a big change no, I still get around 100km per a tank of gas depending on the type of riding.

That's good news. thanks again.

Any updates on this stuff? I just bought an 08 Rubicon CTE. I got 26' Mudbugs, 2" lift, and I recently installed a K&N filter. This thing is handles everything I've thrown at it so far. It let me down once however, it got up to the gas tank in water. It didn't suck any in, but it wouldnt run properly until the next day. And my buddy had to pull me back home with his kodiak. I've put 600km on and thats the only problem i've had so far.

Love the forums BTW.

I have an '05 and although I stay out of deep water I have never had a problem with mine.

I have an 05 500 Foreman with manual shift, HMF Penland series pipe, Dyno-jet jet kit, K&N filter, with 14" ITP rims and 27" XTR's. I've got 5000 kms on mine, it's been dropped in creeks, a lake, and several deep mud holes. All I've ever done is the regular maintinence and a few crankcase and carburetor drains (because of the large amounts of water ingested). My machine has never let me down yet. I run these machines at work, some with 15000 kms on them and still going. If you want something thats going to last buy Honda.

I would like to learn more about cutting the spring in the carb.
I have plenty of power and can get through mud larger quads wont even attempt.My problem is the larger ones can wheelie much easier,being shaft driven the rear rises upon acceleration.So any horse help would be great.

 

[wonderbout'honda']

I did find quite a difference with those upgrades, but what made the most difference was cutting my carb spring in half. Adds a lot to the bottom end and doesn't hurt te top end. The bike wants to lift the front off the ground now in low range when you pin it.

what spring in the carb do you cut?
