my rear end completely locks up when it sits and its really cold outside any ideas what this is or anybody else have this problem
nope i stopped setting the parking brake in the winter cause i had that issue but this one has me worried, i put it in reverse and give it gas and nothing, i can smell the belt burn when i do that and can feel the axle trying to turn but once again nothing happenedIS that with the parking brake set?
Might be moisture in your brake cable if you are setting the brake.
I had this problem just the other week.
i have an overheating problem waters coming out of the water tank boiling, and lots of white smoke coming out of exhaust any HELP?Thought it might be helpful to make a list of the most COMMON mechanical problems/weaknesses that occur on the KFX 700. This list could be helpful for new KFX 700 owners and/or someone interested in buying one.
I'll start the list (in no particular order)...please post below with any suggestions you have to add to this list.
KFX 700 COMMON MECHANICAL PROBLEMS:
1) Stock tie rods are weak / bend too easily; Fix: Replace with aftermarket tie rods and tie rod ends
2) Stock tires tend to wobble / vibrate at high speeds; Fix: Replace with aftermarket tires
3) Stock shocks are too stiff; Fix: Replace with aftermarket shocks or the cheaper option is to replace the front shocks with stock front Honda 450r shocks and the rear shock with a stock rear Predator shock (alternatively, the stock rear KFX 700 shock can be rebuilt/upgraded by GT Thunder).
4) Stock frame near front "spar" area may bend if wrecked; Fix: Avoid hitting trees at high speed :lol: or add reinforcement near spar area
5) Stock steering hoop bends easily if KFX is rolled; Fix: Avoid flipping quad upside down :lol: or add reinforcement to steering hoop.
6) Stock swingarm bearings tend to wear out prematurely, especially if mud riding often; Fix: Periodically disassemble and apply grease and/or keep an eye on them and replace as necessary.
7) Stock intake valves tend to wear out prematurely; Fix: Keep an eye on them and replace if needed.
8) Stock '04 KFX 700 rocker arm shafts had mounting bolts on the shaft that could possibly loosen and fall into the top-end of the motor causing catastrophic damage; Fix: Replace with '05 or later model Prairie rocker arm shafts.
9) Stock tail light tends to break easily if wheelie too much/set on back end; Fix: Install aftermarket grab bar for more protection or aftermarket tail light (slimmer design).
10) ANYTHING ELSE ???
I've noticed that my steering stem is awfully close to my seat. Is it possible that the steering stem/shaft could bent?Steering hoop bends easily when rolled..you can tell by the steering stem end being too close to the airbox cover and from rub marks on the seat/airbox cover. And there will be cracks/rust in the factory powdercoat on the hoop itself.
I've never had an issue with tire wobble on any of mine.
Had my 04 kfx 700 since.... well 04 when I bought it new... haven't had any problems with it thus far...looking for a KFX 700
howdy folks, I've been looking for a KFX 700 for my wife and it seems every one one in my area for sale is an 04. I keep reading about the rocker shaft failure on the 04 models and I'm wondering if I should avoid them altogether? should I look at 06+ models? or is the rocker mod easy to fix, I saw that a member "Nathan" would do the mod, can anyone provide me his contact info? It won't let me send PM's yet. I appreciate any help and insight anyone can provide.
