    Ok guys...I'v almost got the kit done!!!! I'm picking up the resleeved cylinders this week for the big bore kit I've been developing for the 1994-97 vfr 750's. The final displacement will be 837cc and should increase horsepower across the entire rev range substantially! probably around 120 hp or so based on figures given by euro companies who do similar kits. The kit will include 4mm overbore pistons and custom sleeves with EVERYTHING made here in the USA!!!!! Probable retail cost will be about $1050 including the pistons, sleeves and hardware. And based on the dollar/euro conversion right now, this kit will cost euro guys substantially less then what they pay for a similar kit in europe of the UK. Let me know who is seriously interested so I can accomodate them on the first production run!
