kfx450r a "maitenance nightmare"

My kfx chassis is IMO gods gift to quads. I've installed the wide kit and shocks all around. It's really awesome. I just like the ltrs power. Good luck on your buy!

Yep... that's how I perceive it also.

But I have been around a long time, and maybe you have too. It's almost an updated aluminum copy of the old Roll Lobo 250R chassis.... the subframe angle is just steeper.

But if you buy a used one, I'd say the chances are high that you are buying a buggy trade-in. But I can guide you through any troubles.

My advice for good KFX450R service is...

Download factory service manual from internet (free)
Buy 2 multimeters, 1 digital autoranging, 1 analog
($45 for both at Sears or Walmart)
Unhook every connector and put in dielectric grease.
Buy the throttle sensor setting adapter and hook it up inline
Use digital multimeter to check TPS periodically
Never install higher rated fuse in place of a blown fuse... find the problem
Exercise common sense if you use pressure washers

Use very robust synthetic oil... change when it looks dirty in sight glass
(15w50 Mobil 1 in summer, 10w40 Mobil 1 motorcycle in winter... or Amsoil equivalent)
Service air filter religiously when needed.
Don't use K&N filters unless covered with outerwear and used in desert (large particulates)
Disassemble and grease suspension pivot points periodically
Don't install fancy lightweight sprockets ever
Check chain slack and sprocket bolts regularly
Buy a Moose Poly case saver in case anything ever goes wrong with the chain
Put good skids under the aluminum frame

Remember this EFI system has no ability to adjust for mods

Duster you said dont install lightweight sprockets, but the one I am looking at has renthal sprockets front and rear. Is that a problem?

Also I wanted people to tell me whether this is a good deal

2008 kfx450r for $3600
With:
Renthal nerf bars
Renthal sprockets front and rear
DG skid plate
Renthal fatbars
ITP rear tires and rims(40% tread on rear tires)
Also matching helmet and riding jersey
Low hours and a 4 year transferable warranty

[Duster]

None of them aluminum sprockets or supposed to last for ever steel sprockets or such nonsense.

Standard Renthal would be fine.

Trying to shave an ounce or make it last forever just isn't wise for this application.


Tell the guy you heard the extended warranty isn't worth the paper it's written on, and offer him $3,000 or less... LOL...

[NHRider]

I want to talk him down to $3200, would you say that is a good buy? If it has a warranty then would it cover any mechanical problems that could come with buying used?

[Duster]

Sounds good to me.

I'd offer it and I bet he takes it.
