Cool SP2 Race Motor ~150hp

buyer backed out, this thing really deserves its own thread.

This is from the B bike, very low miles and broken in properly. This thing is nice!! and was built with all the best parts. This can be put on a street bike and run with minimal servicing with similar intervals as a stock motor.

cash/pickup Las Cruces, NM

will ship via greyhound

SP2 motor
(148.3+hp/ U4.4 gas) (137.6hp on 87 pump)
port, polish flowed heads,
cams (it was either all intake or exhaust, Josh said he forgot)
JE 11:1 pistons,
GSXR coilovers with the nice NGK race plugs
Speedcell Light Clutch basket (Josh's own design, -1.8lb rotating mass)
crankcase vent
PAIR


SP1 ThrottleBodies w/SP2 injector


this thing should be good for close to ~150hp with a good tune on some race gas.

dyno sheet available, less than 500 miles on the whole build.wicked setup.

Josh also said this specific Dyno was reading lower HP numbers,

He has dyno sheet on 87 pump gas (which is best surprisingly, given the options)


SOLD


(free Durbahn carbon tank pad)

SOLD

-will throw in the Hotcams valve shim kit too

*last pic is just a stock pic, but it will come as pictured.
