26 Sep 2023 03:36CorrectThankyou for your input, correct me if I'm wrong. I should be able to re-use the electronic ignition from my GPZ1100 83-85 and the pickups with the standard timing plate fitted to end of the crank. The electronic timing curve is regulated as revs increase (by the ignition module)

Thankyou, I suppose my bikes have been going too well to consult / read the posts.
I now have a GPZ1100 83 unitrack motor which has been totally rebuilt (just the head to finish next week). I want to replace the standard as new GPZ1100B1 motor in my Franken bike (with 83 cams), this motor develops 95RWH BUT I always wanted the 83 so when a good engine was advertised I bought it,

First Permanent ride the Z1R since Dec1977 (220,000km) as of June 2015
Second permanent bike 1989 FJ1200 dyno'd 140RWH, great bike.
Third ride is now the Frankenstein 1981 GPZ1100B1, 1983 fully recon motor fitted LOVE THIS BIKE
Forth my work bike FJ1200 1989 (same type as FJ above)

27 Sep 2023 11:50 - 27 Sep 2023 11:51That 1100 is really nice Bozo
Agreed 1000%
Would it make sense to install J-head valve components (springs, retainers, buckets, etc) into the ZX1100A head to simplify lash adjustments, comparatively speaking?

27 Sep 2023 12:31As I understand it the "J"head isn't compatible with the pistons used in the later motor ??That 1100 is really nice Bozo

Easily change shims without removing the camshafts, comparatively speaking of course.

28 Sep 2023 04:19 - 28 Sep 2023 04:23That 1100 is really nice BozoThanks again. This particular engine has a J model head, I did clean up the porting. Cams are GPZ1100 83 Unitrack model. Would you believe there are around 17 different motorcycle bits used hence Frankenstein,CBR1000F wheels, speedhut gauges, zx10 clutch lever, ZRX1100 carbies, GTR1400 radial master brake, EX650 brakes (new addition re welded brackets), GPZ900R Front end, GPZ750 turbo swingarm, ZX750R Bitubo Shock (this bike weights 215kg with fuel), marving race pipe plus many more.Handles and goes incredible BUT I still want the GPZ1100 83 Unitrack motor
Daveo, that motor in your picture is Fantastic Porn
