The start to my bobber build, got a lot of things planned for the future, so far all guages/blinkers/front fender/plastics/etc are torn off, then hit the gas tank with aircraft stripper and hammered out some knee dents, didn't take too long and feels nice getting closer to the bike. Just finished swapping out the bars for some zombie performance el guapos and cutting the middle plate out of the riser. The grips are mismatched because the ones I bought (clutch side) didn't come with the right throttle cam. The tank and the bars are unfinished steel, I covered the tank in oil, and will reapply every so often, plan is to let both just hang loose and rust up a little, dont have the money, patience, or manners to deal with nice paint. The master cylinder hung upside down for a little bit, so the front brakes are nonexistent, and I stripped the screw trying to bleed them today, so on the lookout for aftermarket replacement if anyone has some good tips, ebay seems dry rn. Next steps are a seat redo, leaning towards chopping up and narrowing stock seat pan, chopping fender, relocating tail light and plate to a sissy bar, then ear shave, degoat, and lower. But I've got to get her to stop first.

This makes me want a 2nd bike! I've been adding to the stock bike, but the simple stripped down look is great too! Have you considered drag pipes? You can then drop the passenger pegs without needing the exhaust to hang from them. Also, one guy on here changed the front brake to single rotor/caliper, and removed the 2nd throttle cable (closing cable). His reasoning was reduced mechanical complexity, but it is a little more you can pull off the bike.

I like the look of the knee dents. Reminds me of an old Triumph. How much does that affect tank capacity?

Thanks man, drag pipes are for sure on the way after some other stuff gets taken care of. Huh, I've never seen that thread, sounds cool though, might have to dig around. Haven't run any hard tests on tank capacity, but I gotta figure less gas fits in there ;) doesn't seem too extreme to me though.

That member had a lot of out there opinions. When he was asked to tone it down, and was unable to do so, he got an extended time out. The second throttle cable is a safety feature to ensure the throttle could be closed in an emergency, such as when the return spring doesn't work or the pull cable frays and gets stuck. Mechanically simpler without it, but what about safety?

Yeah I did see him getting told off for that, I'm saving the front brake elim and all the sketchy chopper stuff for another bike down the road. The vulcan is staying safe

Hope you plan to remove just one of two front brakes, since that is where more than 70% of a motorcycle's braking ability comes from.

yeah, I've been telling people 80% lol, as this is a super hypothetical build years away that definitely won't be a vulcan, I'm not really stressing on the details yet. Thanks for the concern though!

I wondered where he went...

Both the brake removal and cable removal seemed like a safety issue, but I know some old bikes only used one cable. Perhaps cable failure was how they determined it was wise to add a second cable? IDK. The single brake might be fine if you're not going nuts on speed. I would argue there's safety issues with removing the turn signals and horn as well, and I know many riders don't wear helmets and other gear. But at the end of the day, everyone has their own level of risk assessment.

My bike is built up closer to a bagger than a bobber, so I'm clearly not the simplicity guy.....but I can appreciate the bobber builds! I know a guy that runs without any gauges at all! Me, I added a shift light because...why not?

Past week and a half have been dedicated to my seat shave and the upholstery gods... I wasn't liking the bulkiness of the seat on this bike, wanted to slim everything down, so took the seat off, removed the upholstery and foam, then I did my best to make a symmetrical line around where I wanted to cut the pan.

Its looking good and skinny, so off to home depot, bought some 3 inch foam, and layered it on there with some spray adhesive. Then cut around the edges with a long exacto blade, but a good serrated knife would have been clutch.

Started sketching out the line I want it to follow, once I had that all the way around I cut off more big chunks with the exacto, then moved onto filing and rasping the edges and smoothing it all out.

Looking like a seat, but not quite. Got some marine grade vinyl and tried to stretch it around then was greeted with the reality of compound curves. At that point I was pretty torn between giving up and cutting this down to a solo seat, or going full on and making a pattern to sew. I teach sewing at my student job so I had a feeling I could do it, but that it would be a pain. I started researching how to make patterns for cycle seats and ended up going for it. Covered the whole seat in masking tape, then marked with a sharpie around the top edge. then cut along the mark with a razor blade and removed the masking tape in sections. Laid those out on my vinyl, gave a 5/8 seam allowance and cut out the pattern.

I had a top panel and two sides, if I utilized the material better I would have liked to have one long side piece to eliminate an extra seam. So far, not as complicated as I feared, and a pretty fun way to end finals week. Got to sewing after the pattern was cut, I pinned everything up (right sides together), compound curves and all, Its pretty cool how everything starts to take shape. Then sewed it, this was kind of a pain in some spots and really had to manipulate the fabric to get it to feed through flat. I definitely created some puckers and imperfections in this step as you'll see, but I don't think anything about this build is gonna be perfect.

Its actually fitting okay, so last thing is to actually upholster the seat. Stretched the fabric around and stapled it, simple, just wish I had a better staple gun, don't cheap out on the craft ones if you do this project, get a real industrial one. Its worth it. And not even more expensive, I just bought mine where I got my fabric instead of driving to home depot.

Not perfect by any means, we got some puckers, it looks a little off center, and some ripples here and there too, but I made it myself and it was a cool process.

Here it is on the bike, I like how it sits on the frame now instead of covering the rails. Not very comfy at all lol, but that issue is 100% the foam, not the slimmer profile. If I did this again (which I wont) I would find some way firmer stuff, I'm just sinking straight through this one to the seat pan. So might not have been worth it to go through all this trouble anyway. Lol I do like how it turned out though and was happy I didn't just go to the solo seat. Thats mainly because the next step is a new sissy bar, going to make some cardboard models later and hopefully end up with something that fits the new seat a little tighter, holds a new tail light and license plate, and can handle some luggage. Some motocamping is the goal this summer...

Some small updates, seat is feeling good, liking the direction there, I also put some ls650 shocks on a few weeks ago, which look great. Scraped off the badges on the electronics plate, added some regional pride. Took the mufflers off, left the goat in for now, it has a nice deep idle sound, I didn't much like the sound when I first rode with it, but I rode today with ear protection and it felt perfect. Next things next, got header wrap and mirrors coming in, mine is held on with duct tape right now. Also have the supplies for the sissy bar, just gotta get the fabrication done. The ear shave stuff just got delivered, so I'll do that next time I have the chance, its perfect riding weather now, so might hold off until a rainy day. Coming together one step at a time.

A lot has happened to the bike in a month, but honestly most of it happened yesterday. I earshaved a while ago, uni filters, vacuum plugs and 40/140s, I think I need to change my pilots though, so ordering some 42s shortly. After the earshave I had to replace the battery and solenoid, then onto the fun stuff. Got a mini clamp mirror from tc bros, but if I were to do it again I'd probably find a bicycle mirror for cheaper from a local bike shop.
Yesterday I decided to go to town and figure out a way to realistically mount an old trident sissy bar I got from a moto graveyard, I wanted to have it welded on, but I also wanted it done, so since it fit pretty close, I just drilled some holes in it and bolted it into the fender mounts. Although it slightly pivots forwards, it wont move backwards because of how the frame rails are positioned, so it stays on pretty tight with only one mounting point.

With the sissy bar working, it was time to figure out how to mount my license plate and a round taillight I got from a hardware store (I originally bought a taillight and side mounting plate from tc bros for 100 bucks, I saw a similar light at the store for 8 bucks and immediately returned the overpriced one). The plate was easy enough, two zipties took care of it, the light required a couple more holes in the sissy bar and some rewiring. I ran the ground wire through the bolt on the fender mount. The seat is mounted to the sissy bar with a high tech bandana.

Last things last I grabbed the fender, ran some tape where I wanted the chop, and cut it down, cleaned it up a bit with a dremel, and shot some paint at the exposed edge.
She ain't perfect, and she ain't done, an old school flame paint job is coming later this weekend, I gotta rejet, and might throw some extensions on the exhaust. But I'm digging all the changes and super happy to be pretty much though the checklist I made for this bike.

42 pilot seems like a lot. Did you try shimming the needles?

In my area they would write me up for attaching my license plate with anything other than bolts.
got two shims on both needles, but I'm getting less power before around half throttle, figured thats the pilot lacking, I could try to go back to 38

we'll see if i get harassed about any of this stuff, not sure what cops care about over here

What color are the plugs? It could be rich and losing power.

I had my trailer tag mounted vertical and the cop was ok with it, made sure I used bolts though. Had to remove the tailgate for a load, so the tag went on the fender.

put in new plugs after the earshave, they're looking pretty dark, what do you think about going to 38/140?
That might work, but it might pay to try it without the shims first. Small adjustments.
good call, I'll give it a shot tomorrow, thanks!
I've used those tail light housings on bikes. Simple, look good, easy install and cheap. I used a trailer license plate mount cut down to fit our smaller plate, that works good too. Also, a 1157 flashing LED is awesome in the tail light assembly. Applying the brake causes the LED to flash five times then hold a steady red.
yeah I like the light a lot, the trailer plate mount is a good idea. 1157 brake light sounds cool, there have been a ton of accidents around here lately, could be helpful
Coolant pipe, o rings, and gaskets coming from partzilla. I also got the vn1500 front end from ebay, to settle a few myths about that swap, so far I can confirm that the front wheel fits perfect with the 750 spacers (counting the spedometer as a spacer) as well as the 750 caliper, so no 1500 parts needed besides the actual front end. While I'm working on fitting up that I've got extended 41mm fork tubes coming in, they're a little less than 5 inches over the vn1500 tubes so we'll see how they end up looking/handling. Also ordered a triangle headlight, 5.5 inch risers, and an extended braided brake line. Have debated between 3.5 inch and 5.5 inch risers due to concerns about cable and wire length while turning, but I think they should clear with a little rerouting, and worse case I can splice some wires or get extended cables.
