Cool lookin CB.

I am concerned that the stem you pressed into the triple was spinning!! I had my stem swaps done by a bike machine shop. Cost $100.00 both times. One of the swaps, I believe the the CB stem into the ZX6 triple required a collar to be made for the stem. It was welded and then pressed. If your stem is spinning in the triple, I dont think that can be left like that. Again, I am not a machinist, but this concerns me. You may want to consult somebody "in the know". If that stem / triple fit fails, that can be very bad.

Good luck, and keep the pics comin.:shocker:

I don't really have any advise on sssa swaps but don't those rear shocks come with a pivot on the top mount on the ducati's? Then there is a rod with heim joints on them used to adjust preload...

 

[toyosuprablue]

There is a pivot piece and rod yes on the original ducati setup. I replaced the stock spring with a heavier duty one thinking i could eliminate that. I figured making that original setup to work wouldve been even harder than getting the shock to work on its own

Very cool build. Can't wait to see how it goes.

Thanks! I'm kinda on my own with this (no friends ride) so its hard brainstorming solutions on my own. I might have to break down and go to a local shop with this rear shock stuff.

There's no shame in asking for help from professionals. You save a lot of time and heartache getting the serious structural mods done by a pro. If you're new to fabrication work it's best to let pros do the major changes and you focus on aesthetics. Things that won't immediately kill you if you didn't build them right. :LolLolLolLol:

You could always get it knurled that should stop it spinning.

Use loctite bearing mount.... it wont move again.

I'm with ctluba. I'd definitely address that loose stem. It'll only get looser as you ride. Both of the above are great options IMO. I dig what you're doing here,not trying to be critical,just don't want to see you cut any corners.

I appreciate the advice so no worries on being critical. It was tight enough to where I couldn't twist it by hand, it only began to twist when I started tightening the nut on top. When it all comes apart again for paint at some point I'll probably add loc-tite to it or something similar.

By using the word "twist" when describing the issue I can see how one would picture it being able to slid right in and out like throwing a hot dog down a hallway. That's not the case though

Buddy,I know you don't want to hear this,but that's not tight enough. It's a super easy fix right now. Take it to any machine shop and ask them to knurl that part of the stem. It'll take them about 5 minutes.

Hell,where are you at? I'll knurl it for you. I promise I'm not trying to be a jerk here,but you really cannot take any chances here.

If you opt for the loctite route,which may be fine too, don't use off the shelf loctite from your local auto parts store designed for holding nuts on to bolts. That won't do. There is a particular formula of loctite designed to hold bearings in place that was mentioned earlier here. That,and only that,is the loctite that you NEED for this job.

Fix while you still can. Be safe. And good luck on the build :thumbsup:

 

[toyosuprablue]

Ok thank you shinyribs for the definitive answer on that. I'll have it knurled for sure. Is there any tricks to taking it apart without damaging the bearings? I didn't have to be so careful with the original bearings because I knew I was replacing them.

Updates: I have a sleeve being made now to press fit in the bushings for the swing arm to make it work with the pivot bolt. Hopefully it works out right! Will add pics when I get it back

 

[shinyribs]

Probably the easiest way would be to press it off when you press the stem out. Put the nut on top to protect the threads and you should be fine. The amount of interference fit for the lower bearing race to the stem is probably equal to looser than what the stem should be in the lower tree.


Blahblahblah....sorry...it'll pop off when you press the stem out.

Some update shots




The sleeves for the pivot bolt finally came back. The bike has a piece of scrap pipe where the shock will go holding it up so that i can wheel it around and bring it to the shop for the rear shock upper mount. fun stuff

 

[Shane Liberty]

I am curious,


What are you planning to do with the main chassis to deal with the lateral forces that the SSSA will place on the down tubes? I would imagine you'd need to gusset a few points in the frame to prevent it from flexing too much when leaned over into a corner.

agreed. With the longer than stock arm, larger overall diameter wheel, and beefier arm, the stresses with out cross bracing would make me "slightly" uneasy.

Not something to throw down the tools over because it's not a deal breaker, just something to think about.


beautiful bike and i love the progress you've made

Agreed. It's not a deal breaker, just something to remedy before you're ready to start the finishing touches. Especially if you're looking to powder coat or professionally paint the frame.

Thanks for the kind words guys. Im still waiting for a quote on the upper shock mount. The shop has had my bike for about two weeks now. I will raise those concerns next time I talk to them...

ultimate fighter- I didnt measure them but I think the stock wheel/ tire is larger than my new setup. I'll check when I get the bike back... I havent even begun to look into how im throwing off the drivetrain ratio between the different rear sprocket and everything.

I pretty much just registered to see this project through-- this is a sweet build thread! Any new pictures?

 

[Andler2008]

yeah man it's been almost a month now. MOAR pics!!!!!!!!!!!!!!! This is turning out to be a badass bike.

Thanks Micahgc!
The shop doing the upper shock mount still has it (over 2 months now)... I told them I wasn't in a rush and they got started on some other bigger projects first. Not the end of the world because I wasn't gonna have it done in time to ride before winter anyways. I'm hoping to have it back by the end of next week. I will update with pics as soon as I get it back.
