  1. I have some pics on the pc I could locate ......mine was a 90' gsxr 1100 turbo as well......but the cooler  I used was a setrab 19 row iirc  and positioned on almost a 60 degree angle ( bike was lowered so needed the tire clearance).....just above the front of the swinger pivot and just behind the seat latch .......fan was off a 04' R1 . 

  2. Hey all…. a buddy of mine is starting a complete restoration project 1990 1100 L ….. the body decals are easy enough to find but the warning labels and info labels are proving to be a challenge to source….. any places in the UK that do em ?

    Thanks for the recommendation.

    I've got a probably stupid question, but I've asked a few people and haven't gotten a straight answer yet.

    Since porting the heads should make the motor more efficient at making power with boost, if there were 2 identical motors both making 250 hp, but one was ported on 12 psi, and the other not ported on 15 psi, would the ported one be less likely to blow since it's running lower boost pressure? Or does it only depend on the power output of the motor? 

    Seems like it'll have a pretty straight forward answer, but I haven't found it yet. Thanks 

    #1- Yes           #2- depends on state of tune….. fueling , ignition 

  4. a proper mill with a solid carbide bit will do the job . since you have that extra threaded hole , bolt the cap down and use a steel sleeve inside the bore of the opposite side…. this will be a guide to keep the drill from wobbling around . before drilling …measure the depth of the bore from the top of the cap to the bottom of the threaded hole and set the machine stop … this will keep you from drilling too far into the head….use high speed and constant pressure ( medium) …. the extractor will get red hot and the carbide bit will go through it quickly…..keep the pressure untill you have passed through both the extractor and bolt .  left hand carbide bits are available too and may aid in the process   but  not always . This worked for me and I had 4 of them in the same head  to do .
