I'll give him a shot, thanks so much for all the help already!

So just so all of you know, I'm the brother he keeps talking about. I help him build his bike when i can but myself am currently building a dune buggy out of a 1970 Volkswagen Beetle. I am pretty well versed in working on cars and fabricating parts. I've looked over the comstars many times and i see no problem in the spoke rings. the comstars are held together stock by nuts and bolts at the center hub. we will use SAE Grade 8 bolts, or Metric Grade 10.9 bolts (depending on hole size) and they're shear strength is more than enough even with increased horsepower. the spoke rings are made of 3/16 inch mild steel which is stronger than aluminum. So personally I feel this will be stronger than a stock aluminum hub. Please correct me if I'm wrong.

[seanbarney41]

Only thing is, you will be making it heavier, less round, and less true...this is not an improvement.  Not much point in modifying things so that they are worse than they were before.

Jer's here! Hey buddy! I totally see both sides, but I guess I figure if it's as cheap/easy (ok well cheap is more important that easy at this point, but not at all at the expense of quality and safety) to do the gl conversion, then I might as well. I figure calling price equal-ish, there are performance benefits as well as a stock Honda designed hub and wheels that are already spoked etc, the conversion is the way to go. I've been doing some research and I think I could build a complete gl front end by buying the individual components and keep it fairly feasible. Now I'm just hoping I can still mount my 750 gauges easily to the gl top. We'll see, but I suppose this is all just part of the adventure! ...or something like that.

[B]

Found a guy not 20 min away from me who's supposed to have all the parts I need for the GL front end conversion Spokes with dual discs may not be so far off after all Going to check him out on Thurs... BOOM!

[B]

Oh my word, whose bike is that?? Is that... Is that spokes with dual front discs on a 77 cb750 f?  STOKED! Or should I say... SPOKED! Got it all mocked up with the gl1000 front end and it's lookin like it's all gonna go super smoothly Thanks so much for the advice! Dodged a real bullet goin this way... and it was cheaper! Now to disassemble, clean up/ replace parts, and put it all together for real!

[calj737]

That's a great outcome, B! I think you'll be quite happy you went that route. "Proably" safer and with the numbers of members who've done this exact swap, better technical support should you encounter any issues or questions.

Some tapered bearings for the stem and you're golden!

[B]

Welp, not a whole lot of exciting things to update. I've been puttin in the time, just don't have any pics of beautifully finished parts just yet. I did manage to get all the front brake parts stripped down to bare metal and ready for paint (wish I could do powder, but it's just probably not in the budget). Also got the front wheel disassembled and ready for new spokes and a polished hub!


There's some rust on the inside of the rim that's making me slightly nervous. I'll post a couple pics soon to see what the consensus is... I'd love to save the cash and clean it up, but of course not at the expense of safety.

Most exciting news is I just ordered new tapered bearings for the GL front end conversion, as well as new wheel bearings, caliper rebuild kits, and all the bits for the forks, including progressive springs Now I just gotta wait for a nice enough day in CO to paint and reassemble!

[B]

Also, question. I'm lookin to pick up a spoked f rim off a guy in town who I know has one... Just need to make sure that the caliper etc from my f2 will still work, true? Save for some spacing, the spoked disc f is a direct bolt onto the comstarred f2... right?

unfortunately no, nothing bolt on about it

[B]

Oh no! Haha, well I purposefully didn't order parts for the rear yet for this exact reason. It's never that easy... I guess that's part of the fun? Well at least I knew what I was signing up for! So the front end is good to go with spokes on account of I bought an entire 76 GL front end. That all has been mocked up and confirmed as a success! So what all do I need to make a spoked f (disc not drum) rear wheel bolt up properly in place of my current comstar rear wheel (also disc). Do I need to steal brake parts as well as the spoked rear disc f wheel? Or am I back to the GL thing?

oops, I thought you were talking about the front the whole time...my bad.  I don't know anything about the back.  really sorry

[B]

You put your sorries in a can, cuz I appreciate the input! Heck I appreciate the fact that anyone is reading this and contributing! There's no way I'd be having any success without the wealth of generosity and knowledge on this forum. I think I remember from reading Tweakin's 915 f2 build that when he went to spokes the only issue with the rear spokes was spacing since he did have a spoked f single disc rear wheel. Just not positive, but either way I think I'll pick the wheel up from this guy this weekend (he's clearin out his garage so he's sellin stuff dirt cheap) and mock it up and see what kind of results I get.

Been gettin a lot done, but don't have a bunch of glamo shots to post. You could really drive yourself crazy tryin to pull the bearing retainer... the obvious solution being of course a modified chisel and a crescent. 



My welding skills are shoddy at best, but Jer and I managed to attach the hoop, tail light mount, and this nice custom seat mount... Looks like they'll hold!



If you're wondering where you recognize that sweet led cafe style tail light from... well, it's a trailer light

Also been throwin down lots o paint. I've become a firm believer in the quality of spray paint jobs if it's well prepped! (Arnold Palmer clearly approves as well) Also got a bunch of parts in the mail so once the paint dries I should be able to build up the front end, and lace me up some wheels! Boom!

Thanks! I checked your build out too man, great work!

[Garage_guy_chris]

those cases with the broken studs should be easily saveable, i had the same thing happen. i ended up masking the area off and welding nuts to the broken stud letting it cool then twisting them out. it didnt work the first time on either side the welds broke. But after a few tries they came out

I certainly considered it, but by the time I realized the case had been repaired and I broke the kick start pin, I figured I might as well use the one I had layin around that was free from such afflictions. I'll keep it around though and won't full on scrap it. Thanks for the advice!

[B]

Keepin on keepin on, and polishing a bunch! Gettin close to shiny enough...


Assembled the forks! New seals, fresh oil, and progressives (tighter coils down of course, otherwise the performance would suffer greatly, as I hear it reverses their effect, completely screws up the preload, discalibrates the capacitators, and causes the punting of sweet little baby puppy dogs worldwide...)    Also got those tapered steering bearings from all ballzzzz installed, so I'm officially runnin a gl1000 front end! Only problem was the gl1000 dust covers I ordered were too dern small! Seems to be the only mis-ship though, so overall things are cruising along nicely!

[B]

Calipers built...


... and mounted


Swingarm's all did! Tried to use some brand new zerks from Harbor Freight... broke one and two others leaked. Luckily I had a spare swingarm layin around, and the old stock fitting worked like a charm! Shoulda thought of that in the first place... 


And lastly... My spokes came in!!!!! It involved more head scratching than I care to admit... and was actually an unexpected pita, but it is in fact true... you too CAN re-spoke a wheel!

Dude tao and la flama are two of my all time favs! I plan on using your top end build thread when I get there... Looks like it'll be invaluable. Stoked you're here! Might just have to use ya for your knowledge and skills

Agreed! I love how much bigger and meaner all the GL parts look. I'm just glad you guys talked me into it… definitely the way to go!
