Lol - great - I installed new grooved EBC shoes - and a new cable - and lubed up the pivot points, so that’s a start. Next I may work the trick that Tom mentioned about using sandpaper in the hub and “matching” the shoes to the bore. But before I make more work for myself, I’ll try and adjust them.

Most DLS brakes are very sensitive to setup, pads and clearances. And the added bonus for trail use that they have ZERO
braking force rolling backwards :shock


I found this procedure on the web, is this the correct way to adjust - or are there other “tricks”


“1) Have the axle tight and the wheel up in the air so it spins freely
2) Back off on the link rod so ONLY the shoe connected to the cable lever is going to rub (rod fully in, rotate down)(one rub per wheel rotation).
3) Adjust the cable adjusters until the that one shoe drags very lightly
4) While still at this cable adjuster setting start changing the link rod length until the linked shoe starts dragging then go a little more on that adjustment, 1/2 turn or so (two rubs per rotation).
5) The linked shoe must contact first and drag harder in this light application so as to make up for the slack in pivot bushings etc
6) Test ride a bit and stop and try adjusting another 1/2 turn on the linkage, it may even be better but this is the definitive way it must be done to get them both to grab.“

Another pic of the bike, and I also just ordered a Hi-Flite blue seat cover for it. Ugh - I went to a lot of pain to get that black Hi-Flite cover

Wile you have the seat off you may as well paint the frame red :biggrin

Lol - yeah - I should have taken your advice on that one too.

So the “updated” plan is to paint the frame on the spare bike, then swap parts over - but right now it’s low on the priority list, but that’ll happen (might take years at the rate of progress on this one)

Even the wifey pointed that out when she saw the bike :omg:

I have a couple parts left to source - I need the airbox and I take “bands” or basically the clamps - where do folks spice these from? I see the OEM PNs called out are NLA. I assume I can just measure the tube OD, I want to install the correct parts and not run a “hose clamp”. TIA

Copy the P/N from Partzilla and put it into fleabay if you want NOS stuff.

Bike looks terrific Steve!
Valves are STILL for toilets!

Thanks Todd !

I did try that trick, but nothing on eBay, just seems to lead to dead ends searching the web. I’m sure I can do more research on it.

I take this info and search the snot out of ebay and the web. Someone must make replacement clamps for one of those bikes.

Or

Buy this, take the clamp, clean it and resell it for the same price. :)

Slowed down again on the build, since there’s no events on the calendar (in the near future) that are definite.

But installed the new seat cover this morning

Hurry up! When there's no events is the best time to finish builds, once racing starts there's no time.

Wings installed. Now working on properly installing the silencer - I just had it mocked up on there.

Also - I ordered a CR 80 air filter cage off eBay for $25 (I never got one with the bike) and it’s an exact fit, so if anyone in the future is researching a replacement, that’s the one to source. (Thanks goes out to Tom for pointing me in that direction)

Need to pickup a couple fasteners at the hardware store, and a clamp for the silencer, then put some fuel it it and hope it works as good as it looks !

Well I like that ! Thank you Darrell.

I’ll have to swap it onto the CR, it’ll probably gain some dBa, but it’ll look very cool.

I wonder if I can get that graphic made that’ll handle the heat.

Here you go Steve. It’ll hold up just fine to the heat.
