Help for DesmoDue Newbies

As sure a few of you are aware it can be difficult to know where to go to find up grades and just general race kit for the desmodue race bikes.

I am starting this thread to pool together information that we have with the intention of creating a stick post (or adding to my stick want to be a dd racer?) with aproval from MT if this is with in the advertising rules
with list of companys and where to find help when building a race bike and finding spares.

Example

http://www.ricambiweiss.de/ For race fairings

http://www.hcracetech.co.uk/ Also race fairings - Matt T sponser

http://stores.ebay.co.uk/Race-Supplies-Direct For rear sets and clip ons (what size do you need?)

Race exhaust system by MHP

http://www.racinglines.co.uk/ For race suspension work



That type of Idea

I would also highly recommend Maxton Suspension not just for new units but for refurb'ing forks and rear shocks.

New springs to suit rider/bike damping mods, full services and bushes etc..

First class @ http://www.maxton.netspinners.co.uk

They are always very busy so email....don't depend on the phone calls being return quickly

Dom,
Rather than have many individual posts on one thread, can they all be put into one list???

A few to add to that list would be.


http://www.jacexhausts.co.uk/index.html

They did the exhaust system on Matt's bike.



http://www.ultimate-finish.co.uk/

Did Matt's frame and a frame for Skid's.


http://www.carrotcycles.co.uk/

Converted 748/916 throttle and cable to be used on a 583.

I have used Ohlins springs for a 748/916

When adjusting the air gap 6.25cc of Oil = 5mm of Air Gap
Fork leg tie wrap to be approx 5 mm to 10 mm off the bottom of the fork leg
(thanks to Chris P for the air gap & volume info)

(do not forget to use a smaller spacer above the springs to give you the correct static sag, as the 748 springs are longer than the standard Showa's.)

Will give a more detailed suspension settings over the weekend ( if thats ok with skids )

Spring rate will depend partly on your weight with riding gearing on.
I go to Race Parts for my springs as I get a good deal but have to wait for them to order in as they only stock balanced pairs for the car racers. Otherwise try K-tech or JHP

Btw... I have made a simple but affective ride height adjuster to
use with the ie shock. (I'll post up a pic when it's fitted)
I did plan on buying a new shock but this credit C has hit work hard
so i'll make best use of what i have for next year!

Will the shock supplier need to know the bike weight etc?
Sorry if i appear dumb..lol

Fork springs want to be around 0.9kg/mm

Still awaiting the 2009 ACU Handbook, main thing that worries me is any change to noise regs and I'm also keeping an eye on the sizes they allow for the Race numbers.

also just got to say I've had a couple of sets of K-Tech fork springs delivered very quickly by Brook Suspension in Bradford
www.brooksuspension.co.uk
just make sure you give them a delivery address where there is someone to sign for them, otherwise like me you will find the depot of the courier they use is 50 miles from where you work
