I don't know where better to post this, but this section seems appropriate since it's going tobe pretty technical :D

I'm bringing this in here already well into the project, but thought it might be of interest here so I'm sharing :D

I've already cut and adjusted to get my final stance in place.



Still quite a lot to do, though! More to come soon!

You can see the project from the beginning here: Honda Shadow 750

Wow! I found this interesting, but I thought this project had died, like so many others which start with the best intentions.
I find the fork swap has my attention, the 750 ACE needs more brake if you speed it up, EBC HH sintered pads can only do so much.

I hope this sets a trend and other forgotten customizations start to surface.
The run of the mill "by the book" bobber isn't too exciting to a forum voyeur.

Oh no I just started this project in ernest last week. This was easily the more lucky fork swap I've ever done but I don't know that it'd work well with a standard bike. I'm running triumph forks and they're a fair bit shorter than the Shadows forks, and also the speedometer pickup is fully integrated into the front wheel. It might be a but difficult to adapt the speedometer over.

Could go with GPS speedo.

I'll be running a GPS setup. There's certainly ways to work around it, but I'd hate to lead anyone down the path of doing something like this on the premise that it's easy and bolts right together with no issues :)

I thought the project was older, probably I'm thinking of another.

The fork length loss might not be such a bad thing.
How much difference is there? Just approximately.
As for the speedometer, somebody makes a box that probably can sort out the difference, I can't think of the name of the company off hand.

The engine can come to life fairly easily as long as you don't mind losing low end torque, but it quickly gets to the point where more brakes would be good, so this swap has caught my eye.

The shadow forks are 32" from axle to top cap, the Triumph forks are 28 3/8". It's a pretty good dive, but not completely ridiculous.

Tank mounts and seat rails in place. Still a long road but it's nice to see the seat line finalized. There will be an additional brace underneath curving away from the arch of frame's backbone but it won't disrupt that wheel-seat gap very much.

I kinda have to think this is how Erik Buell got his start. Shortening the fork and changing the attitude of the frame should effectively reduce the rake and quicken the handling. I like it.

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...

Why would you 'cafe' an Interceptor? Someone will be doing a Hayabusa one next...

Would there be any way to put a spacer on that sprocket, and then mount the sprocket to the spacer using bolts or something?

The guy I got it from gave me the impression of someone who's head was thoroughly screwed on...albeit maybe against the thread.

I can't use a spacer on teh front sprocket because of the way it's retained on the shaft. I might could possible mill the carrier down but I'm not 100% certain I can get enough material off of it to line up the chain AND clear the tire.

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....

Like 300 width tires on a car. Look AWESOME! May require just a little bit of work to make them fit… 😄 That tire isn’t much narrower than the ones on my cars…

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.

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.
