DR350 supermoto project on a KLR budget

[dbarale]

Probably my last post in this thread...

I just love this bike. The new 15/45 gearing is perfect with the 140 rear, at least for my needs.
I need to put thicker oil in the forks (too quick on rebound right now), tune the exhaust and the carb but I am otherwise done.
I love this bike, it is just too much fun.
The gas mileage seems awful but I have yet to rig a speedo to confirm and I honestly don't care.
Did I mention I love this bike?

Does anybody know which years of the GS500 cush hub are thin? I think some are thicker, and don't want to buy any more "wrong" parts.

They are all the same from 89-2011.There was no change.

Cool. I can tell by your blog that you know your GS500's. I got it ordered & on the way.

Thanks,

Just for reference the measurement in red in the pic below is 42mm for the Katana sprocket carrier. 27mm for the GS500 carrier.

Also the DR350S stock spacer between sprocket carrier and hub can be used as-is for the GS500 wheel. No need to machine another one...

Good info.Thanks.

Mo' brakes... Mo'tard...

So at first we had this:



OK for a dirt bike or just putting around. Not what I want on a motard.
So I upgraded to this, GS500 rotor and DR350 caliper on home-made relocation bracket:



Much better, but while the braking power was there the feel wasn't great.
So here is the latest and greatest:



Now we're talking. 1st gen Bandit 1200 caliper on another home-made relocation bracket. Big pads that use all of the surface of the rotor, 4 pistons so that the side loads on the bracket are minimal, much better feel and the pads are not even bedded yet! To the point where I'm wondering if I am going to switch to a stainless line as I originally planned. Might be a bit too touchy...



Next pic is an attempt to show the clearance between rim and caliper. Kinda tight, about 15mm:



If anyone is doing the same conversion and wants the relocation bracket to use the DR caliper on the GS rotor, it is available.

I think the engineer types say "a mm's good as a mile".

Or is it machinists that say that?

I like that brake set up.

The photo makes it look like 1-2 mm. 15mm is over 1/2", it looks a whole lot closer than that.

But, you "obviously" know how to measure!!

Good job.

Yeah, the pic makes it look a lot worse than it is. I double checked and I can slide in the tip of my pinkie. So it's probably closer to 10mm. Just glad I won't get muddy with this one as it would definitely clog up.

How is your motard conversion going? Any progress lately?

is that a 150 rear tyre and did it fit in the swingarm ok?

No, it's a 140. See below...

Not enough miles on them. They have a really round profile, quick turn-in for sure... I do not expect more than 2500 miles out of them on the street.

Edit: Also comes in 120 frt and 150 rear...

ah ok, cheers for that-very helpful :)
