Engine upgrade
Posted: Mon Jan 22, 2007 5:03 pm
For my KR special, I'm hoping to modify the engine as well as the chassis. Powervalves would be nice, as would a big-bore - or both ! Maybe transplant a top-end off a MX'er or something ? We'll see.
In the meantime, I just found this. Looks like a development of the Rotax tandem-twin motor, as found in old GP250's, karts and microlights etc : BRC 250FE
Electronic/pneumatic powervalves, cassette gearbox, dry clutch, programmable ignition. 90bhp !
£8500 + VAT.
Ah well, the sprocket was on the wrong side anyway...
