I'll sketch something up later and post it

Ok, thanks.

Question about welding the brake and shift levers on my rearsets I'm making. Are they chromed? If so do I need to remove the chrome before welding?

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

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?

My opinion: you will want to rotate the toe controls farther "up". From the picture, they seem to require your toe to be hanging pretty straight down, and not inline with the natural line of your foot. I like very much where the rearset bracket is, not too high, not too far back, very comfy. But I suspect your foot will really have to extend to push the brake especially.

DaveBarbier · « **Reply #382 on:** January 22, 2015, 04:43:23 pm »

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.

Of all the things ice bought, had shipped to me, and boxes I have lying about, you'd think a box to ship a swing arm would be easy. I've gone through 14, yes, 14 different ones and still haven't found one that fits. I did notice one at a motorcycle shop the other day, but it had a customers parts in it. Begged the GM not to let the customer take the box and that I'd return for it....

Fingers crossed!

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.

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

do you know how wide exactly it needs to be overall? I may have an aluminum spacer from a different application that will work- Or just use a SS washer/spacer. Tricky to find 1 in 25MM ID.

DaveBarbier · « **Reply #394 on:** February 04, 2015, 02:15:02 pm »

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?

DaveBarbier · « **Reply #396 on:** February 04, 2015, 02:36:54 pm »

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.

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.
