I have a BUILT 250x motor for sale. Ive built several 350RX bikes over the years and this was going to be my motor, but I have sold all my bikes and frames and now have nothing to put it in and have no plans on building another bike – so now its for sale.

This motor made awesome power, but it was leaking a little oil – nothing bad just a little more than I felt comfortable with – I knew this when I bought it. so I dropped it off at my engine guy a long time ago and just got it back yesterday – he replaced and machined the two inner cases and put it all back together.


Anyways, the details:
250x cases machined for 400ex sleeve

13.5:1 JE piston (400ex piston – 440)
8mm stroker crank
Largest valves available
HD valve springs
HD clutch springs
High lift web cam
HD cam chain and sprockets
Ported and polished head
Titanium valve guides
Lightened flywheel
Reverse gear is removed

It will come with :
Head pipe made by Bud Fischer, White Bros. muffler
Wiring harness with pro design kill switch
CDI – curtis sparks hi-rev and coil
39 mm FCR carb
Throttle and clutch cables
Kickstarter and shift lever
Intake tube

Ran on vp 112 and kendall 20w50 oil

Honestly I don’t know what its worth - I talked to the guy that did the motor and found out how much work/money has gone into it. So at this point Im open to offers.
Please call if you have any questions – I’d rather talk to someone that try to explain it over emails or pm’s

Thanks

its a 440. as far as HP - i dont know. has tons of torque, easily runs with a 450r.
