Next bullet being assembled at Redax

Postby maxene5 » Mon Oct 18, 2010 2:44 am

so while everyone on the team went to Phillip Island this weekend the poor old engine builder stayed at home and worked on the teams new race engine.
Red spent Sunday machining the primary drive side to lose weight, by using one of Andy Chain's Duplex Merc primary drive chains we were able to remove the outer row of sprocket teeth and all of the overhang material.

Then machining the clutch drum, pressure plate and clutch hub gained a few more grams.

Image

Total lose off the rotating mass was 0.448 grams so far.
more to come.

Next up will be the crankshaft, more photo's to follow as the build progresses

This is shaping up to be one serious engine!

Very smart Red, as always. Work is brilliant, and just goes to show how some extra thought can create good results. We all look forward to seeing this motor spin up...
Didn't go to Philip, but did participate at the last test at Wakefield, and the bike now really flies,with excellent handling and brakes to compliment motor performance, so the new motor should have it in the clouds...
Monty build continues well, with tyres sorted and suspension build well underway.

further update
needed to get the engine cases finished so that they can go to the specialist coaters on Monday.
Red had to machine the top engine cases so the larger cylinder liners would fit.
Intended capacity will be 1175 cc with 11:1 compression for this engine.
Attached photo shows the cases being machined.

Image

Cases are going to have thermal dispersion coatings applied.
As the build progresses you will note that there is going to be a lot of different coatings used on this engine, mainly on the thermal side as we aim to reduce engine operating temperatures.
But we are also going to coat the crank with oil shedding coatings and of course all the main parts of the head in ceramic coatings.

Photo's to follow in due course.

This is just getting better and better.

I think these over-sized jap bikes are going to have some real competition now... :twisted:

okay, next few photo's

we have the cases and primary cover back from the coaters now
engine is now black, rest of the covers, barrels and head will also be black when they are finished
this is the thermal dispersion coating we mentioned in a previous post
looks quite different, is a semi gloss finish, close to satin finish
plan is the hand paint the "LAVERDA" on the primary cover in, well, Laverda orange of course

unfortunately this is as far as I got with this engine this break, am back at work earning the money I need to keep playing with Laverda's and I will not be home again until early next year
but am confident that I have everything in place to build the bottom end, assemble the cases and install the barrels by start of Feb.

Head is a different story, plan is to use a current head we have in stock that has had some serious porting work done to it by persons unkown, not all of it done well but we have already run this head on the street and it performs okay after we filled some of the port shape back in with good old JB Weld.
This will be a stop gap head so the team can start to use the new engine while we get a head finished.

Tchau

Woooo Hooooo special order black engine ... now your talking. It looks mean and I know it's going to be mean to, can't wait to see it fire up in the Spaceframe, very very cool indeed.

Hi Maxene & Red, I have the privilage of riding the Spaceframe as it is at the moment. The engine you have supplied us is just ideal for our current development, rider, team and bike. The new engine will take us to another level and I am very much looking forward to riding the bike with this additional power. It is a good feeling racing with a well built engine. Cheers Blair

well not much happening on the engine now until I get home from work in January sometime
so thought I would post some photo's of the engine Dyno that we have just purchased
This is a Stuska XS19 unit, rated 0-200 hp, water brake type, currently set up to Dyno Race Carts

unit is still in USA but will depart in next 10 days or so
am now looking and pricing Data Acquisition packages for the unit
there are a few available from different manufacturers so am waiting on their replies to tell me price and availability

once unit is at home, probably take me 4-5 days to modify the unit to suit the Laverda engine, make the engine plates, frames, fuel tank, ignition system, water tanks, etc.

addition of this Dyno will allow us to do some proper testing, tuning, trying out new ideas, no more guess work

exciting times in Laverda land at the moment
