  1. As this is the start of a very long journey of prototyping,  me like the thinking @gixer1460 approach of cams and springs is the budget end of tuning I'll go that way as the spring board.

    This will be my first in tuning a multi gsxr so any advise as i go is always appreciated.  Thank you for all for your input.  I've done the two stroke tuning thing and many a four stroke but things have moved on greatly so one needs to get up to speed.

    Right, I've done the big bore by adding rf900 crank, rods,pistons, barrels from three or four sets and weighed them till i got a matching set. All within half gram or less. Yippee! 

    Crank? Balance and lightened? Or just check for balance? 

    Head will just be" milded clean " in the ports, exhaust port polished. Done this before on 750 and worked a treat. Good starting point. 38mm from 750w/p with ramair socks. Carbs will be fettled with rebuild.

    Should keep be busy over winter.:D
