No you can't, the diameters are different.

Box'a'bits came around this morning and gave me guidance on rebuilding the forks, he's had a bit of experience rebuilding forks recently while fitting WR forks to his R100GS http://www.advrider.com/forums/showthread.php?t=612774.

We disassembled the forks completely, cleaned everything out, fitted new seals and they are all reassembled again ready to go onto the bike.

I took the new forks for a run out to Ocean Beach last Sunday, it's a mix of gravel/dirt track and sand. plus about 90km of seal to get there.

The forks handled pretty well. They pogo'd a bit on the seal at 60km/h but were pretty good at 100km/h. I had all the adjustments wound right out so fully soft, except the stuck compression adjuster which is stuck at about 25% in. I'll have a play with them over the next few rides and adjust the tuning a bit but so far I'm happy.

umm, I'll have to check. It's the stock DR650 wheel I was using with the original forks and it didn't do it with those.

Even without oil, it shouldn't do that.

Steering bearings too tight?

Steering bearings and clamps are original DR650 ones and weren't altered during the upgrade.

After going back and forth through the options for upgrading my '06 DR650, I've decided I like the DRz250 fork swap option the best. Reasonably cheap, simple, easy adjustment, reliable and most importantly an improvement.

Out of curiosity though, is there any difference internally between the lower fork tubes of the 250/650 when completely disassembled? Could the 650 bottom be used with the 250 cartridges, negating the need for a calliper spacer?
