Finke set up


Hi

I have just sent off an early bird entry to the Finke and now have to sort out my CRE. This would be my first Finke and I would appreciate any set up tips.

It is mainly jetting and fuel economy which I just don't have any idea about.

I will keep the motor basically stock apart from carbon reeds and a FMF fatty pipe and muffler - what jetting should I go for ?

With a 17 litre tank - how far will I get ? Will I be able to skip a refuel stop - ie travel around 130 km on the tank ?

If anyone wants to join forces in travelling - I am located in Canberra

thanks

regards
Lex

Re: Finke set up


Im in regular contact with the boys at Desrt Edge who are GODS when it comes to the CR500, heck they got the weapon to win 12yrs in a row!
 
Anyway this is the run down that Ive learnt from their experience.
 
Gearing: 15/36 - but this requires the rear hub to be machined down for chain clearance.
 
Gear Box: 5th gear installed from a pre 91 model so the leap from 4th to 5th isnt so great, the newer CR500's have a taller 5th which bogs the motor down at high speed in deep sand.
 
Clutch: Im not sure what they use but will bet its not standard.
 
Carby: They have tried them all & say that the pwk [sign in to see URL] is best, but they get it bored out in a special way, imagine an upside down snow man, so at a lower slide position its still a 39.5, but at full rpm its around 41mm - this keeps her strong down low & helps fly up the top.
 
Jetting: 190 main! This is to keep her from toasting itself at full rpm for long stretches of desert, Im not sure exactly what the needle position is or what type, but it is raised, & Im not sure about the pilot but do know its not such a big deal as your rarely in low rpm's
 
Reeds: They custom build their own by using the stock reeds, cutting them & over lapping them with a fibre reed, similar to boysens but much stronger. They told me that V-Force reeds are lucky to make it one way without disintergrating!
 
Barrel: Ported & polished to what they call Finke specs (probably similar to the mo-better porting the US boys talk of), keeping just the right amount of bottom end while getting every bit of top end possible.
 
Head: Squish band modified to better suit unleaded, as they told me "the head was designed back when super was the go & never got changed to suit the charachteristics of unleaded"
 
Plug: At least the equivelant to a B9EGV, if it was in the 8's there would be a Chernobyl between your legs!
 
Piston: Honda genuine piston with a ceramic coated dome and teflon coated sides to help go the distance while withstanding the extra heat. They wont go near wiseco, refuse to even sell them.
 
Exhaust: They ALL run FMF gnarly's with Power Core 2 silencers, I was told they give the strongest pull & are the strongest in design (being 1/8th of an inch thick)
I have tried the standard, a pro circuit, and the FMF, & like what the FMF does "all round".
 
Engine: The crank is balanced which they say gives up to an extra 10 - 15 kph up top!
 
Flywheel weight: Some run them, some dont. Its an individuals preference.
 
Wheels: Something stronger than standard, as there is a lot of square edged holes & big rocks on high speed sections.
 
Suspension: Plush, its got to soak up the above mentioned & hold steady at 170kph + (110 mph) on the soft desert sand! Awesome.
 
Steering Dampener: Ive been told the "Scott" steering dampener is the best & by having one you will gain 15 minutes at least on a one way run, let alone the energy it saves you.
 
Fuel Tank: Clark 17L will mean only one fuel stop but can be more tiring, the standard means 2 fuel stops.
 
Fitness is just as important as pre-running the track they tell me.
Their a top bunch of blokes at Desert Edge and are very approachable, hide nothing and are 100% helpfull, talk to Michael Vroom & you cant go wrong.
Good luck & I wish I was there this year, being the 30th anniversary it will be BIG, hopefully next year! It would be good to have a CR500riders meeting at the Finke!

Re: Finke set up


I wish I read this before buying Moto Tassinari VFORCE3 reed valve for my CR 500. I don’t hold it flat for hours but I wonder now if the thing is going to fall apart in my engine
