Congrats on the bike. I didn't know the Gpz 1100 were fuel injected?
Oh well - Your RWHP was probably around 80-90 - thats a guestimate, but has lots of potential to do more. Isn't your bike air cooled?

First piece of advice.

1. Get service manual or Haynes/Clymer books.
2. Dump all the fluids ( oil, brake fluid) unless recently changed and start your service records as CHIEF Mechanic
3. Check your hoses and tubes for wear inside and outside and replace.
4. Inspect your brakes, brake lines and throtle cables - oil them. I just found a broken throttle cable on my Ninja 900 and replacing it before it becomes a real problem.

More to follow

rwhp=rear wheel horse power
it's supposedly 120 at the wheel, but kawi service manuals had a history of UNDER-rating their horsepower, that's why i was wandering if anyone had dyno'd one.

the 84 gpz1100 has the 18mm wrist pins and the heavy crank, it is the core that most racers use, has all the go-faster goodies of its era.

it's also oil/air cooled in response to your earlier question

The number reported is not RWHP it is HP at the crank....... The number at the crank will always be higher than the rear. The real world number is RWHP as that is what your bike will really create for you.
