Sounds like a good plan mate ...
Some great info online to get lots of ideas to play around with ..
9-1 ratio may be still a little high to go upping the boost above 12 psi ??...
It will blow the engine into eternity much higher boost than that ..
I ran mine down to 6.5 to 1 ... it had not much down low ...but chit it reved up to 14.000RPM in an instant at the lower ratio .... like a bloody high speed electric motor she was !!!! ...
I personally think like yours , maintaining the slightly higher ratio and keeping the boost lower with what is already a very pokie( high torque :-) motor like the 1000F , is the best idea..

LoL Dpasch it didn't take you too long to get on this board. I had posted the details of the bike on here a few years ago. Probably buried now. I have a video clip of the bike that I made a few years ago. No way to attach it here unfortunately. Maybe I'll youtube it and post the link.
Oh, and the clarify, I think it is running around 10:1 compression. I was only running 8 psi on the street, 12 psi with race gas on the dyno. Still made 155 hp @ 7psi. And it's not the turbulence that is wrecking the top end, it's the lack of plenum area in front of the carbs and the bottleneck in the exhaust manifold where it meets the turbo.

well i got the bike home yesterday first thing i did was tore her apart...took the head off cleaned combustion chamber...valves were perfect,checked the valves didnt even have to adjust they were all in spec...so i guess i should explain the reason i pulled the head was due to scott saying it was only running on 3 cylinders anyways got that all back together then spent 4 hours taking the carbs apart and cleaning them an making sure they were spotless as i was cleaning them when i got to the final carb i found the reason it started running on 3 cylinders...4th cylinder the main jet was jammed with a chunk of rust... so then i was looking at the balancer and notice she was all the way to the end so im pretty sure ill be ripping the engine apart an putting a fresh cam chain and tensioner and new alternator chain and tensioner an new starter chain....my next thing is to figure out what to put on for a tail section because the one that was on it ( not stock) just looks out of place and well i wouldnt mind being able to 2 up so i need to figure out what would look best

ok so the front end is off a 97 gsxr 1000 i know scotty had to do a bit of work just to get it to fit. i did not do it but i do know he had to mod the dash to get more movement so you can turn the wheels...im going to be putting in a custom dash, right now no speedo is setup because the 97 1000 ran off sprocket and not front tire, so ill be putting a acewell on it and customizing that to do what i need...i havent had time to even work on the bike due to me having to do a engine rebuild on the truck so thats taking priority
