Yo,

I thought i'd throw an update at you as its been a while.

We have finished the stinger section on no1 cyl and mounted the springs. Only cyl 3's stinger left to do.

Modified water pump finished.

Wiring loom all-but finished

Porting 2/3rds done.

A few things are getting in the way at the mo so serious progress might be a month away.

At least the weathers fining up here now.

Cheers
Jared

I have removed the water return (larger diameter) pipe (on the water pump housing)and replaced it with the next size up, this combined with the three separate return pipes from the cylinders gives a 20-30% increase in water capacity on the return side. The pump side is under pressure so the diameter is fine.

We have modified the way the water flows around the cylinders forcing it to do a full circuit of the barrel before exiting. We have a top double core and bottom chin radiator with a thermostat the can send the flow through the chin rad only when the temp drops below a certain threshold.

Hopefully this will be sufficient for near doubling the performance of the engine.

Cheers

hey bloodnut, is that a screamer motor or a big bang motor you are making? if it is a big bang, then why the double ignatecs? why 3 pickups? have you set the crank to 3 x 90 degrees or are the bottom 2 cylinders running paralell ?

Hey Luggy,

Firing order is standard, ie the bottom 2 cylinders fire together and the top cylinder fires 90 degrees later. This engine was big bang 7 years before the gp bikes!

We are running dual cdi's so we can set the rear cylinder up individually, 1 cdi looks after the bottom cylinders and 1 for the top cylinder. This will allow us to adjust the ignition to suit the different tune of the top cylinder (hotter, different inlet and exhaust shape etc).

cheers

Are you going for maximum power on the top cylinder, or give it an easier life as she is on her own ?
