Title: DR 500.
Post by: Curly3 on May 30, 2011, 08:39:57 pm

I recently tested a DR 500 engine that had been raced on Road Racing in QLD.
I scored it on ebay with no idea what had been done to it.
After stripping it down, short of splitting the cases, I found that both the balancer shafts had been removed along with the kick start shaft, complete.
The ports have been opened up a fare bit and the compression has been increased, no idea what ratio and it didn't have a carb on it so I have no idea if it had been run on Methanol.
I fitted stronger valve springs and used my standard carb with plus 10% main jet.
What a difference from a standard engine, rough down low but once it hits peak revs the vibe goes and pulls like a train.
I have to sort the jetting out but its a huge improvement.
Unfortunately the first chance I get to compare it with the pace setting big bore Yam's & Honda's will be at the DT titles in Bris next month.
I'll keep you posted.

I know it doesn't sound as exciting or exotic as a pre 75 or the Holy Grail pre 65, but I a Zook guy and I'd love to get one to give the TT/XT & XR bikes a decent run for their money.
I've got a pre65 project on the go but am relying on others to be able to move ahead.

No offence taken Mick, how's the leg by the way?
Was that this years Dakar Cloggy and was it a class result or outright?
