Craig races for fun

Hi all!
This is the final version (for now) of my race
bike. It is a GS 1000 with a strengthened frame,
steering damper, GSX swingarm, Wiseco 1100 kit,
Alternator removed, Dyna 2000 ignition, wider
alloy rims, flowed head and 33mm smoothbore
carbs. Estimated output, compared to other race
bikes is around 110bhp, but I will dyno it later
this year and let you know. It pulls from very
low and is smooth all the way through the rev
range. No major problems yet, apart from
crankcase pressure pushing the crank end seal
out and trashing the Dyna pick-ups on the
ignition side of the motor. This was fixed by
building a new breather flange at the top of the
motor and using a 20mm breather hose. |

No
more problems ... apparently this is a common problem
on higher horsepower GS motors.
New mods when I can afford it
will be to fit new Keihen 35mm smoothies (lighter and
flow more) and some slightly hotter cams. I also need
to modify the alternator cover which is regularly
grinding out, and fit some rear-set footpegs, as the
pegs are now half their normal length due to grinding
up the track.. At the moment the brakes are standard
calipers, but some Brembo twin pots are lined up to go
on the front. |
The
race class is called Post Classic over here in
New Zealand, and all items fitted to the bike (except
a few small exceptions) have to be pre-82 or
replicas of pre-82 components. This means no
upside down forks, flat-slide carbs, 4 pot
brakes or other nice modern kit. It keeps the
build price of the bike reasonable though, and
this one is competitive (not the rider though..)
for around US$5000.00. We get all kinds of bikes
including Katanas, Kawasaki Z1s, TZ Yamahas,
CBXs, Hot RD 350 Yamahas, Honda CB400-4s, Honda
750 single cams, Honda 900 bol d'ors, Honda
CB1100Rs and so on....It's a great scene, with
very friendly people and I love it!
If anyone is interested in more info, let me
know.
