Very happy,
And I would build another in a minute it is a totally different bike just turn the throttle and its on the back wheel no clutch needed.
Things to keep on top of, compression ratio will increase with a stroker crank and it needs to be kept under 12:1 to run pump fuel (here in Australia the pump fuel is rubbish)
I would get the xt crank stroked next time to 8mm and a 105.5mm CP piston/barrel will make 804cc and run the xt flywheel & stator.
The DNA Stage 3 air box is a must.
And the clutch needs a lot of work to hold the power but it can be done, mine holds now.
The gear box is a worrie, will it hold ??? Ok so far.
And more, if you get serious about doing one let me know and I will help you out. But beware of
