OEM Crankshaft for a 2010 KX250F. It's been machined & lightened, balanced to within .001", with a new rod and bearing. It was just balanced by my local tuner Steve Balboni. It only fits 2010 cases. I unfortunately learned the hard way having an

Yes it includes everything! 5 gears on the output shaft, as well as the shaft itself, and all the necessary washers etc. On the input side there are 4 gears plus the shaft which has one gear casted into the shaft itself. All treated in ISF/REM. What ... more »

Added reply in a thread 1.85 rim ok on a 450? 5/3/2015 9:31 PM
it will work but not ideal. Especially if you plan on using a 120 wide tire, it becomes quite a chore mounting tire in my experience. Also, the wider 2.15 tends lay out a wider footprint of the tire once mounted giving you extra traction for the 450 ... more »

Yes, because I also bought a used cover & the previous owner didn't include the PC impeller.

All i needed for my 09 with the same setup was one longer additional case mounting bolt like you mentioned. I reused the OEM impeller, washer, and bolt.

I see an opportunity for the aftermarket parts to develop these. That would be a nice feature for sure. EDIT > *Quick google search shows a constant need of pressurized oil in the cylinder head for these to work. So therefore a redesigned head would ... more »

681.. Exactly what I was thinking, it would have been the hot setup to put the updated transmission gears into the 09 cases. I remember bringing the 09 into Chaplin Kawa back when the bike was new to get a safety bulletin work. I'm not sure what they

Today I had the crank runout inspected by a local machine shop. It was within spec. I couldn't believe it. So I went back and assembled the cases without the transmission. It went together with ease. Then I tried assembling the motor without the crank

Paw Paw: Oil screen is just not shown in pics, it was installed after. I will have to check run out; I don't own a proper dial gauge but tracking one down is my next step. I had a Hot Rods crank kit, but sold it in favor of this unit, which is the box ... more »

The crank is claimed to be a factory kawasaki part, but it looks like it may have be a machined and lightened OEM unit with a new rod. After taking the cases apart the 1st time, the main bearing from the Left case stuck to the crankshaft and was removed

The engine is a 2009 KX250F. I am using a new crankshaft, new bearings, transmission was ISF/REM coated and a whole bunch of other money was thrown at the bike. Not that any of that matters. I have pressed the crank into the right side crankcase and ... more »

Only thing you'll need is the updated style fender hardware. In 13' they changed the 4 fender bolts which have a wider diameter spacer/dowel than the old bolt. In other words, the bolt holes in the plastic fender are a wider diameter than the previous ... more »

Nice. The "before" look is already impressive, looking forward to more pics of the "after". I have an 07' YZ250 that needs a little love so I'll be taking notes.

Thanks Circus, I'm not sure If it will work in my favor or not but I got it for $185 plus postage. I guess its essentially the opposite feeling of mounting a flywheel weight.
