OK gents, sorry for the delay... been very busy.

1277 motor has;

Lightened Bandit crank 9kg, Carillo rods, JE pistons,Web cams Inlet 0.385" Exh 0.370", ported head, 30/26 valves, APE valve spring and Ti retainers, RS40 carbs, dyna coils and lots of tuning.

[How much bhp?]

My stock 1127 all original was 120 RWHP. 

After 4-1 pipe, pod filters, jet kit it made 133 RWHP.

Then it became a 1216 with web cams and RS40s - 152 RWHP.

Then with big valves - 165 RWHP

Then it was sleeved to take 1277cc and a higher lift exhaust cam got over 170 RWHP, best run was 173 HP

[GSXR1277 progress]

After starting racing with a stock 1127 with 120 RWHP several years ago I am now campaigning a 1277 with a best run of 173 RWHP (done on the same dyno). 

Plenty of life left in these old oil cooled beasts.  DYNO 1277.pdf
