Talking about carbs, I installed bigger pilot jets and smaller main jets today. No time to go to the dyno before next race but I intend to run a 9.5... period.

I REALLY? do hope you acheive you ambition to run a 9.5, against me on a 9.6 dial.

GPz won't be finished in time for Sam to ride it but the project continues.
Here's a before pic of the "new" undamaged engine cases.

I started the Harley today, it had been sitting in the shop for a year... gonna change the oil tomorrow, check a few things and then we are good to go. I noticed the throttle body flap thingies (I'm sure there's a real name for them, but I'm a carb-guy

) don't open completely at WOT so I'll make some adjustments tomorrow. Could be worth one or two horsepower

I think 140 will be plenty.

139 to be honest

Waking up the old thread, it's been a while since I worked on this project but it is still going on and perhaps Sam will still ride it some day

Need a thicker base gasket and the engine is good to go.

I am watching this build on the GPz. I am currently building an '83 GPz 750. Initially it was supposed to be for the VRRA but the class that it would be allowed in will make me look like a joke. Theres some serious muscle in that category. I may have to convert it back to a street bike and think about another race bike. something smaller perhaps. I wish I could find good info on the GPz. I need some advice on building a stout street motor. Cant wait to see this one finished.

Hahaha, im well aware im no drag racer. Not going to even try and pretend. I get my kicks in the turns.

Being a Finn I'm not familiar with the VRRA rules, anywhere I can find them to go and see what you mean?

K_Kalynuik · « **Reply #111 on:** January 24, 2014, 01:14:35 PM »

Yup - http://www.vrra.ca/wp-content/uploads/2012/05/VRRA-Rules-April-2012.pdf -

The 83 gpz 750 would have to be in the F1 class of Period 4 Superbikes. Bikes allowed up to 1989. Some cases newer if the model unchanged. The Gpz will be greatly under powered and under suspended. have a look through the rule book if you like. Its long but I read it like its my bible.

Thanks, sounds like the classic road racing rules are very different compared to Europe. I'll have a look.

I was supposed to finish this bike ages ago but now that my brother has a job, he showed me the green light. This project continues right now

Sam Green Racing · « **Reply #115 on:** December 17, 2015, 03:36:57 AM »

Well hurry up then, hahaha

I just bought a GPz, but it's a little one - 550....

Thanks, it should sound healthy with all the time and effort put into it

The paint on the cylinder head smokes when it gets hot for the first time.

Leino · « **Reply #122 on:** March 24, 2016, 05:43:05 AM »

Next thing to solve is the rear brake and lining up the chain. My brother is highly motivated all of a sudden for some strange reason so I think the bike will be ready in a month or so.

Leino · « **Reply #123 on:** April 19, 2016, 02:03:26 AM »

Oh well, my brother is in France now. Working on a cruise ship.
Nothing going on with the bike... again.
