Here are the rear sets so far. Seems to work smoothly. Just need to pick up some heim joints and threaded rods.

Nice looking mod.

Thanks, but not my design. Dustin Kott from Kott Motorcycles does this design and I replicated it. Turned out pretty good though.

Finally finished up the rearsets. Very comfortable but the real test is when I'm riding. Can't test that for a few months, ha.

Made my own little stainless turnbuckles and they are very adjustable. It seemed that I could have ordered a linkage set but that would have been more expensive but also I heard most of them don't have one end as a left hand thread, so it's not really a turnbuckle. Is that the case for anyone that's got the linkage from DCC or elsewhere?

I also do have to bend the kickstart lever a bit to clear the brake pedal. The footrest is fine but the pedal is about half and inch in the way. Probably need Oxy Acet. for that, right? Would MAPP gas do the trick?

The shift side feels perfect. The brake feels good too but it's hard to tell for sure because it's not hooked up yet, so yeah, you could be right. But it can be easily adjusted. Now if I can only get a swing arm to put my rear tire on...haha, just kidding! No pressure, plenty to do still.

Took the kickstart lever to a local garage and had the guy heat it up and bend it out slightly. Worked like a charm and only cost me a six pack of beer. Beer as a currency is a great idea. So rearsets are pretty much done.

Got my new to me swing arm from Cal! Thanks a lot! It cleaned up really nice. The pivot bushings and shock bushings popped out relatively easily. I'm painting today so might finish it up and toss it back on the bike earlier this coming week.



Also ordered some stainless M6 1.0 zerks from McMaster Carr. Drilled out the pivot bolt with a 3/16ths bit and tapped it with my M6 tap. 3/16ths is a bit small, calls for a 13/64ths but if you go slow with a lot of oil it'll be fine. I just didn't want to mess with the old style that some people seem to have trouble with. Plus any chance I get to drill and tap something I'll take.

Install those zerks with some thread lube or sealant for good measure.

Was planning on using blue Loctite. But do you mean like a sealant to prevent grease from leaking out? I have the Loctite 518 which I used for my cases (wonderful stuff). It can also lock threads and will make a good seal to prevent leaks.

Might as well ask here, but anyone can answer: Just to double check, this 1975 swing arm has the exact same measurements as the 1978, except for the axel spacing. It's 1/8" wider. 10-3/4" vs 10-5/8". That can just be made up with a spacer, no? Could I run into chain alignment issues? Might have to make 1/16" spacers for either side or just an 1/8" for one side?

Dave what ever you do don't over tighten the grease nipples (zerks??) and snapped one of them as I did, it was a pain to get the bit left in the bolt out.
Dave you've gotta start using metric rather than imperial- you yanks imperial on a Jap bike, next you'll be using metric on Triumphs and Nortons.

Ok, thanks Mick, I'll be careful.

Bump again for the swing arm spacers. The '75 swing arm is 1/8th" wider than the stock '78. When I put the wheel on I can tighten the axle so it pinches and closes up that 1/8" and at that point the front and rear sprocket is pretty much perfectly in line. Is that ok? I'd think pinching the swing arm isn't good. Should I just get washers to make up the space or get new spacers machined? I'm thinking '75 spacers wouldn't work because it'll be going on a '78 hub and might make it TOO thick and spread the arms apart.

Thanks

I totally didn't even realize Micks comment about using metric measurements, crap! For some reason I go back and forth. Probably because I'm a Swedish born Yankee. I got to stick with metric!

Maybe I tightened the axle a bit much and slightly closed the gap but now the gap seems like it's about 1.5mm. With the axle loose and the wheel pushed all the way to the right with a 1.5mm washer it seems pretty dead on right now. But it depends how dead on it has to be.

Here's a picture. Close enough for rock and roll? If not, the right side spacer needs to be shortened a bit and the difference added to the left spacer.

Dave I sure got a rise out of you on the metric/ imperial measurements lol. I personally hate the metric system.

Dave are sure the straight edge is 100% straight? Are you able to get 2 spacers that are .75mm, what about getting a machinist to make 2 for you?

Haha, I have rulers for measuring length in all kinds of units but not metric! Inch, picas, points, agate...I'm surprised I don't have parsecs for Jebus sake.

And Cal, thanks for the offer but I'll find something. I have to put an order together from McMaster Carr anyway, might as well get an aluminum spacer from there...and while I'm at it, maybe a metric measuring tape. ;)

Dave I didn't wish to hijack your build and start an argument against the metric system, America's stand against metricifaction  is a topic for another

On second thought, it probably was unnecessary to use that straight edge, even if it's 100% straight. At a weird angle it could look aligned and at a different angle it might look way off. Not to mention a phone's camera lens has distortion. But just looking down the sprocket like a rifle sight it seems very in line. I guess the real test would be to take a longer straight edge and put it up against both sprockets, or a string like you're aligning tires.

I know zero machinists and finding spacers is actually a pain now that I've just looked. It all depends how perfectly aligned it has to be. I was planning on going to the hardware store, getting a big stainless washer and drilling out the inside if it doesn't fit on my axle. It'll probably be something like 1.5 - 2mm in thickness which should be fine.

Haha, no problem. Hijack away! If anyone wants to talk about any random thing on my thread it's fine by me. I wouldn't call it an argument, though. Just a friendly discussion. But I like the metric system. ;)

The real issue you'll have is cornering, if it's not tight it'll slip sides ways and you'll know then if you need to get spacers.
The bronze bearings I got arn't super tight on the swinging arm bolt and I'm wondering what they'll be like when riding.

The swing arm pivot isn't what I'm asking about, but is has zero play and feels really nice in the frame. I read about a lot of people having issues with rebuilding their swing arm, but for me the process went really smooth.

And don't get me started on Swedish music. Big fan over here, ha.

Got a 2mm thick stainless washer. Works perfectly. Now the sprockets are perfectly in line and axle is tight. Thanks Cal for the present!

Projects looking good Dave, the rearset mod looks neat. I've been able to find answers to some of the same swingarm questions I was having myself too, so thanks.
I'm a fan of your painted parts drying setup, looks very homely.

Thanks Bootsey, and yeah that drying setup worked well. I'll have to try to find more parts to paint.

Mick, here's some pictures. The spacer looks so insignificant now! Might have been able to get away with just pinching the swingarm arms together but that didn't feel right. It'll have enough stress on it while riding.

The spacer is right to the right of the chain adjuster.

Where did you get the cam on the brake shaft?  I see DCC has the shifter cams for sale but no brake side?

Hey guys, just a double check on something. I'm rebuilding my forks and was checking the fork spring length limit. The minimum length in the Clymer says 425mm (16.73") and mine is 475mm (18.5625). "What's the problem?", you ask. Well, that's my issue, it's SOO within spec that I'm doubting the Clymer. Are these measurements right? Does the spring have enough length to be able to compress 2 full inches and still be within spec? I know I have to trust the book, and I normally do but this just put up a flag. Could they have switched the 400 and 550 measurements accidentally?
