Making the 1150E rotors work was a trick in its self. .370/.370 cams, Andrews coils, 10.50:1 pistons, 41 mm forks from an '83 GK model (to replace the stock 35mm ones), '83 1100E aluminum swing arm, '84 1150E 36mm carbs, etc., blah, blah blah.
I use that bike as my test bed for all of the things that "you can't do" with these bikes as well as some easier ones. You probably can't make out the '93 GSX1100G foot rests that "don't fit/ can't work" also.
Three decades of parts from 9 different models.
Header is V & H, muffler is Kerker.(< with my baffle inside) Third set of gauges as the first one quite at 121,000 miles, broke the second one when I hit past 145 on the speedo in fourth gear at 7,500rpm. (140 speedo. whoops!)
I have had that one for over 35 years, with six different engines (750, 850, 1000, 1085, 1100 and 1115) and over 170,000 miles.
The 1100 was only replaced because it started to leak a bit of oil after every ride at about 85,000 miles. I got tired of spraying it and wiping it off.
Not a drop of oil had ever hit the ground or even the frame. The others were only replaced because I could.
The same cams, HD valve springs and coils have been in it since it was first turned into an 850 when it had 5,000 miles on it. (because I could)
