Hi all, anyone here got full engine specs for the supersprint 135 bhp X Flow?
Am currently building a second engine and would like to look at something hotter(currently 1660 - 118 bhp).Any other specs to look at without going all steel exotics?

Cheers

Don't take this as gospel but I believe the following:
+90 thou overbore
BV ported head (41.3 inlet, 34 exhaust)
Kent 244 cam
High comp pistons (1300)
Pair of 40DCOEs

I'm currently building one to a similar spec, but going with bike TBs and Megasquirt/

Mine just had 30thou oversize 1300 pistons, lightened rod with decent bolts , a Kent BCF2 cam kit (£45 from ebay) Duplex timing chain kit , steel rocker shaft and pedestals , Steel flywheel again from ebay £45, Vulcan 11a unleaded head ebay £230.Using Kawasaki T/Bs on home made inlet cost about £150 and an Emerald ECU . Engine had full balance and was set up on Emeralds rolling road and had 127BHP at the flywheel with 115ft/lbs torque
