FINALLY got my R1 wheel! Much to my consternation, though, running a 190 is very tight in the swingarm. I have less than half an inch on either side...might be okay though...I'll get to play with it more after Christmas, I only had time to slap a makeshift "axle" through the thing to check it out. Still have to get a cush, carrier, and spacers to make sure it all fits between the spars. If it all lines up then it's custom axle time!

Okay so I finally had time to go and mess around with this and see how far off I'm going to be....and I hate it. That fat 190mm tire was exactly what I had in mind from the beginning, but getting it to line up and clear everything doesn't look like it's in the cards. I'm roughly 9±1 mm difference between the sprockets and even if I decided to go ham and just shift the wheel to the right to sort it out the tire hits the frame. A 180 on this 6" wheel would probably give me the clearance to run offset, but it's not "right".
Wheel centered...


Wheel pushed all the way right...


My options are:
1. Swap it out for a 5.0 or 5.5 rear wheel and run a 170 or 180. Both will look fine and honestly the 170 is a little more suited for the engine. So I will be on the prowl for an R6/FZ6 rear wheel assembly...or maybe even an Enkei/Honda 6-spoker from an F3 or a 900RR.
2. Offset front sprocket...if I can even find one. The retaining clip means I'll probably have to have a sprocket custom made...which I don't care much for. Sprockets are wear items and I want to be able to buy replacements. Not only that, but the way the shift shaft is positioned...which makes me think Honda really didn't have this kind of build in mind when they designed this bike...means that if I actually can find an offset sprocket it'll be very close to the shift assembly. I think the wheel is the better place to resolve the issue.


There is a crazy third option, though, that I picked up today...


Now, I am crazy partial to single side swingarms...and normally I'd be all over this idea...but I'm not 100% certain here that it's the best fit for my Shadow. First, I would either have to mill the middle out of the pivot tube on this one and get crazy with reinforcing itand who knows how the hell I'd get a shock on it (pro-link would not be an option unfortunately), or I would have to find a 650GT swingarm...which isn't impossible and would itself fit the project wonderfully AND it's shock mount would not only allow me to run a more conventional rear suspension..but it'd likely force me to do it.
I'm mulling this over for a while...I think the single side swingarm can solve some of my issues but introduces a few others and the added effort and expense probably means pushing the shadow back late spring and building my GL500 instead (which will be a more traditional build that will be sold). We'll see.
I do want to say, though, that this VFR is easily one of my favorite finds EVER. I go around and buy no title/no key/doesn't run beaters cheap because everyone thinks they're stolen...and I get a lot of interesting bikes and interesting stories. This one is literally at the top of my "nah it wasn't wrecked" list and comes with the explanation that it "only needs a battery and the carburetors cleaned" to run. Yeah you bet lol


















...the adventure continues...

Remove the metal from the wheel/sprocket carrier to get the chain run, looks like you have lots of sprocket off set you can play with

PBI makes custom offset sprockets or I can turn you onto a guy I know that can probably fab you one.

Later, Doug

So I swapped the tire out for a 180 and made an incredible difference. It doesn't look as awesome with that fat tire back there but:

...the wheel now centers with the frame neatly...



...the sprockets now actually line up really nice. The driven is actually about 3mm outboard of the drive but I can have that milled off the carrier...



...there's now a HUGE amount of room to play with all around the brace...

...

...the tire still looks plenty fat but I can't believe there's that big a difference between a 180 and a 190! I absolutely cannot believe how much of a paint in the ass it was to remove the tire, though. I have been manually changing tires for 25 years and have never once had one be this hard to pull off the tire. We're talking even tires that have been on wheels out in the sun for 40 years have not fought me this much. And I can't believe how much difference the 180 made physically. Because...oh....



....ohhhhh....

Cut the ends off of my R1 axle and had my machinist push some bushings in to I could use it as a sleeve for the Shadow's axle.



A real hangup on this has been finding a left side axle spacer for the R1. The few I could find were being sold for the cost of a small child...I just couldn't bring myself to pay more than $10 for the part. Eventually my brain said "hey I bet Craftsman mades a spacer!" No way, I thought, but went over to check my supply of Craftsman spacers and sure enough I had one sitting right there.



A little cutting and a little trimming and the stock shadow spacer plus a couple 20mm washers on both sides and the wheel actually sits center. I'm pretty sure the chain is lined up good, too...I'll know for sure tomorrow when my sprocket gets here.

lol I don't know who matt is but the one special little guy goes by "themotoworks" on the cafe forum...his real name is "sean" something or other. A whole boat load of them are crazy hurt over the rear suspension so I made this video for them after finally getting the correct spring loaded onto the shock

Fuck, I was I could rep that 😂👍🙂

I feel like I've been looking at this bike for months without making much progress, and suddenly making up for it over a couple days haha.

I got the seat hoop done. It could be prettier but most of the "rough" is going to be hidden. There's a couple of braces that need to be added but I ran out of wire...will have to finish that stuff up in a couple weeks.

I got the rearsets set up as well...they'll look better when they're not blue. I really like the positioning but I don't think the shifter is going to work well. I'll have to tinker with that quite a bit.

I got my new sprocket in...I hope to get that on and a little of the wiring sorted out tomorrow then it'll be parked for a while as work interferes.

Why can't I get stuff done in a timely manner? Because of distractions. Today will be the last day I get to play in the shop for probably two weeks and I wanted to finish up the electronics tray and at least start on some wiring...but eight degrees outside and only a little warmer in the shop. I've always heated my shop with a waste oil burner and sometimes it works awesome but usually it makes a lot of smoke and not a lot of heat...so I spent most of my motorcycle time converting it to a wood stove :/...less time for motorcycles, but my shop was toasty.



Electronics tray is set up....I wanted to have had the harness unraveled and some of it tidied up but oh well.



Without much time to actually do any real work I decided to take stuff off I don't need. There's SO many hoses and unused brackets now...all emissions stuff.





One of the things that's baffled me about this engine since starting this project is that it's a 750 but it looks HUGE. It dawned on me while stripping off emmisisons hoses and brackets that this water cooled bike has air cooling fins on it...why? For looks. I'm not sure if I'll leave them off, though...the fins on the bottom are cast into the jug so they're there permanently and it looks a little goofy with half the fins. I'll decide later. The top end looks considerably cleaner, though, without the 500 tubes running around.
