I am going to be selling my 998s engine in parts soon.
It has had a lot of work done by Chris @ CJS - Flowed and blueprint, balanced crank, 749 cams for higher lift, bigger inlet valve, 1038cc (102 rebore), pistal high comp pistons, etc.
I am planning to keep the rods and the corse gearbox. Rest is for sale.
Complete Heads + barels + pistons - Looking for £1400
(which is about the price of the rebore service -on a barrel exchange at Kaemna - where this was done. Here you get the whole set, the pistals, and the heads with all the work for this price).
The bike only had 1 trackday since the work was done so all the work pretty much like new. Depending how you set up the compression, you can see up to 170bhp at the wheel.
