Next project in the Skunkworks

[Pezz_gs]

Took my head to Smiths Engine Research and had a little chat with Wayne Smith who will weave some magic with the inlets, maybe looking for 1mm bigger inlet valves??

I am also looking at Fluidyne Powerflow Radiators


High Performance Radiators ensure modified motors maintain peak horsepower by increasing the efficiency of the cooling system.
Water passages are 33% wider than stock for improved fluid flow.
Radiator cores are thicker than stock, providing increased surface area, cooling and durability.
Rugged construction features aircraft quality aluminum for strength.
TIG welded tanks, furnace brazed aluminum cores.
Billet filler necks assure leak-proof sealing.
Beaded inlet/outlet hose connections for positive sealing.
Direct fit design - no installation modifications required.
Race proven by Baja 1000 and GNCC winners.

Nice! what are they worth?
I bought that carby I was looking at, should get it next week then I just have to install the sucker

Whilst waiting for some parts to come in, my mind has been wandering to other matters, mainly suspension.

I am aware the DRZ400's have limited rear suspension travel and being as I dont stand on bikes, my 'leg issue' again, I have been chatting to a couple of friends who know more than me

I remember seeing one modify the swingarm and dogbone linkages on Kevin Schwantz's Safari DRZ400 to give the 300mm rear travel. So the swingarm will come out and head to his workshop in the next few weeks.

The other, Paul Rooney will rebuild the shock and forks to be suitable and give me plush suspension!

Should have a sweet handler then

longer swingarm should make it a weapon on the hillclimbs

I wonder what length, swingarm pivot to axle, measures on an RMZ450 swingarm????

Suzuki are usually quite easy to swap components around.

EDIT: jsut found out its the same as the DRZ @ 590mm mmmm

I will get the Swingarm mod done then

[Pezz_gs]

Well got a free 30 minutes and decided to start the deconstruct.
They come apart easy, the other way will take a bit more time

It went from this



To this



To this

Hi Pezz, I can offer you a couple of hubcaps from Morris A40 OR Morris Oxford, which would you prefer??

I will need to see some photos

What I have in mind will make you grin

giving me ideas for the other DRZ i got pezz
keeping an eye on this one. Would love some awesome suspension on mine. The motor is already good, once its worn out though i'll probably bore & stroke it with one peice valves, but not upping the compression too much.

Hey Pezz someone just sent me in the direction of this program http://www.bikechecker.com/home.phtml

I just bought the program and its a cracker, its meant for push bikes but you can change the parameters enough that it'll work with motor bikes.

You can use a template or take a photo of your bike, plot the pivot points, enter the parameters and then you can change things.
The program will show you what effect your changes will have on lever ratio and a load of other things I don't understand yet.

Happy to provide ideas Jake, where do you get the one piece Valves?

I need to look at 1mm over inlets only

That looks great Joe,

$25 for the persoanl version. Which one did you buy?

Be good to work up the design of some offroad girder forks I have been contemplating.

Professional version's main benefits compared to the Personal Version:

• pivot force calculation with force vectors drawn
• several cases of force calculation
• more diagram graphs
• comparing graphs is not limited to two comparisons
• export all result datas in text format for spreadsheet import or CAD processing
• custom shock characteristics curve editor
• no limitation on simultaneously opened projects

Personal Pezz
I'm going to struggle understanding this one so the professional would be a waste of money for me.

I've been trying to work out a linkless rear end for my project bike and I had been plotting points on paper to figure out what changes have what effect on the lever ratio and then some one sent me a link to that program which shows way more than I could do on paper.

Its showing a few interesting things about shock position that are giving birth to more ideas.
