Nightmare, waiting for parts is a bloody pain. Especially when you get sooooo close and there's a diflap widget pin missing which costs 10p and stops the whole build!!
As an aside, did you hear Smads engine destroyed itself?? Seems he couldn't resist over revving it despite knowing 10500 was the motors absolute top limit and it finally broke a rod and totalled the motor. Few too many trips to 11000 looking for that last bit of power and now it's $$$$$$$$$$$$
PLEASE work out your safe rpm limit and set it in the programable ignition unit!! less than 500rpm can mean the difference between fun or distatser!

Yeah he sent me a few pics, made a right mess but it's his own fault unfortunately for revving the knackers off it! Been advised to cap the limit around 10250 
it'll be making plenty of power at 10k, in fact all the ones I've seen tail off after 10. He's having it repaired and sleeved now as the TSS barrels are not obtainable anymore - bummer

Yep, after all he went through to get it going it'll be making plenty of power at 10k
Simple way to be sure is there's a calc involving rod length and rpm etc. Derives piston speed and then look to keep it below xxx mtrs/sec. Seem to remember 21 or 26 mtr/sec is the happy zone but maybe double check. It works for every motor and even high revving motors like the S1000RR keep their piston speeds within the zone.
Nice thing is it tells you where your safe zone o even if it's making power way lower, you know you have a safety margin of x rpm if you want a bit of over rev, without destroying the motor.

You're hell bent on making me do maths aren't you :P
Cheers mate
If it saves you adding up the repair bills, then yes!! Cheers mate

so don't believe a spoken or written word from him. Wobbly was a reliable as a British Summer but knows his stuff. Steve is just a Snake Oil Salesman. The song and dance thay made about the 90 degree cranks was farcical Point is Maths can be used to verify pretty much everything rather than relying on some dubious individuals promises. Just goes to show how much demand there is for a decent 500 2T bike!! Measure twice, cut(pay) once!!
But yeah, you are elegant and simple with well known components and such. Smads i think just wanted as much as possible without understanding the set up and it's characteristics and limitations, hence where he's at now.
Mind you, i did the same running my X7 on pure Tolulene(Octane Boost). When like a rocket for about 6 miles then showed me what it was made of, literally.
