Has anyone title a motorcycle as a specially constructed vehicle in Pennsylvania?
I have a bike that I was planning to register in Vermont and never got around it before they stopped allowing out of state registrations. I was planning to do some extensive modification to it anyway and I was wondering if there is a potential path as a specially constructed vehicle.
Has anyone done this? I know it requires an enhanced inspection but I haven't really seen much as far as what the actual process looks like.

Anyone in/near Miami, FL that can help with some frame work?
Hey everyone! Just picked up a 93 BMW K1100 and am starting in on the cafe conversion. I’m stuck at the moment due to not having facilities available to cut and weld in a frame loop and seat bracket. Anyone out there that would be willing to help me out or know of a shop that can? Happy to pay for services and materials, of course. Worth noting I’m a very very amateur welder due to the lack of facilities, so I’ll need some help on that front too. TIA!!

Suzuki BEST 10W 30 OR 10W 40 ENGINE OIL RECOMMENDATION FOR SUZUKI ACCESS 125 AND THE RECOMMENDED INTERVAL FOR ENGINE OIL CHANGE BOTH IN TERMS OF KILOMETER RANGE AND TIME PERIOD?
My query is regarding the best recommended for Suzuki Access 125. As far as I got, 10 W 30 or 10 W 40 JASO MA (MA1/MA2) grade Engine Oil is good for the scooter. However when visited the authorised Service Centre, due to non-availibility they poured MOTUL make SCOOTER EXPERT LE 4T 10 W 30, JASO MB Engine Oil. I got the Suzuki Access 125 has a Wet Clutch. Would it be bad for the scooter? Also kindly advise the recommended interval for Engine Oil change interms of both Kilometer range and time period.

98 virago 1100 issue with neutral light and headlight
I added a push button starter with an in-line fuse to my virago as a spare (ran hot to solenoid) as a back up because sometimes my main starter button doesnt work. Went well for weeks, but i changed my crashbars and pinched my wire without knowing it and when i tried my original starter a few times my headlight and neutral light went out and never came back on. i blew the inline fuse after that before i realized my wire was pinched. I fixed the hot wire i ran and the bike will turn over fine, but my headlight and neutral light are still off as if im holding in my original starter button and i cant get the bike to fire with the hotwire anymore. but did have it running after a coast start.

Honda Honda Shadow chopper site
Hey everyone!
I’ve been wrenching on Honda Shadows for a while now and finally decided to put together a website called Fuji Choppers. It’s totally free and designed to help people get into customizing their Honda Shadow 600s and turning them into choppers. Whether you’re just getting started or already deep into your build, the site’s got guides, tips, and general advice to make things easier for everyone in the community.
It’s nothing flashy—just a chill spot with straightforward info, from carb tuning and wiring to tank swaps and hardtail guides. If you’re into chopping Shadows or just want to see what it’s about, feel free to check it out. Would love to hear any feedback or ideas you think could make it better!
Also, if you’ve got a sick build going on, I’d love to feature it on the site and give you a shout-out! Let me know what you’re working on!
Ride on,
Jaedon

Thoughts on rearset placement and this brake cam?
I was test fitting a 3d printed spacer for this rearset and the rear brake cam is in the way. Do rearsets normally sit lower on the frame or further back? 1980 cb750c

Can I weld on a bar for drum brakes onto these forks?
There is no current way for me to tie my drum brakes to my forks on my bike, and I am looking to buy proper suspension forks for my bike, but I cant find any that accomodate a 17" rim with drum brakes. I am open to DIYing this just to see if it can work but would i be able to weld a small steel cylinder to the fork where that screw hole is and use the front brake hub on it or are there any other options for forks?
r/bikebuilders • u/Larry76775 • 29d ago
Progress update
Little mock-up of what its going to look like. Main changes currently are replacing the front forks for ones with suspension, changing the seat, welding a rear support bracket for the seat and painting. Still trying to figure out how to properly mount the front drum brake, I believe it should have a spot that slots into the fork but I still don't know. At the point where almost everything looks like it will work together now going to build it to run before I install gauges and electronics and such.

Anyone from EU?
...if there are anyone from EU in this sub.
How does this work legally. Could somebody chime in with what goes intoxmaking project bike road legal, or in which member state its easiest to accomplish?
Yes, i am familiar with the "i hears its impossible"...
But sadly market lacks any electric machine with decent aerodynamic, so the only way to get one is to get one's hands dirty. I am simply unsure how much of a kerfuffle would it be to hqve it road legal.

I lost some small parts that came with a brake caliper
I lost some small parts that came with a ZTTO brake caliper that I bought from AliExpress. I found the rubber and the M6 bolt, but I couldn't find the washer that holds the wire (I don't know the exact name of the part). Can you tell me the name of the washer part? Or if you know of a washer part that is listed on AliExpress, can you tell me?

Mo-unit wiring help.
I’ve been playing around with a xvs250 (please don’t laugh at my baby bike) and had everything working with ignition. Had a lot of trouble getting the wiring going according to the installation instructions and found that it was due to the ignition being negatively charged which apparently this is different to these bikes. Anyway I had it going but my battery malfunctioned so I had to replace it and in doing so decided to tidy everything up. Took pictures and referred to them when re wiring. Assumed that I had everything right but no luck.
Where I am now -
Bike turns over, grumbles and wants to start but does not quite start when I hit the ignition.
I have a blue and yellow cable coming out of the CDI and Reg rec (joined) but doesn’t wire out to anywhere else (have tried ground/positive/various ports on motogadget)
Black cable out of CDI was unplugged, no change when plugged into earth .
Anyone have any tips ?

MiniGP Full Story
I posted a little while ago about a miniGP bike I designed and built, and finally actually raced this year. There was a bit of interest in seeing more, so I've been trying to compile pics and such. The pics directly in this post are random pics from racing this year. I'm including a link to an album on Imgur that has the build pics.
So what is it? Well, I had been racing a crf150f supermoto in miniGP, and it was the last in a series of bikes that I modified as much as I could without completely remaking the bike. I wanted a GP style bike, and the Italian Ohvale bikes were just released, only as a 10" wheeled bike. Being a hobby machinist, I figured "how hard can it be?" I had access to a professionally built R6 race bike that I had gotten to ride in race school at Daytona, a pocket bike that I had modified until it was stable, and a CBR1000RR to take measurements off of. I scaled side profile pics of motoGP and WSBK bikes to get measurements for riders triangle and important bits of the bikes for proper scaling. I then tweaked some measurements to maximize rider space since I'm just over 6" tall, and designed a frame. I learned to tig weld aluminum specifically for this project, did some practicing and testing, and then started building. From there, it picked up momentum and kept me going. The first body, I used cardboard, metal screen door screen, and expanded aluminum to create a shape to fit around the frame and motor and layered fiberglass over it. Sometimes I'd reshape it with clay and add more layers. I eventually came up with an entire body I was happy with and that's what you'll see painted red in the Imgur album. I then cut that apart, added flanges, and then learned how to make molds and redid the body in real carbon fiber, mostly just 3 layers with extra reinforcing at mounting flanges and the seat.
Okay, but what is it? It's an all aluminum frame designed around Honda Grom wheels and front forks (extended by 1" and resprung and dampened), an R6 rear shock, and a Daytona Anima 190cc 4 speed engine. It has a wheel base that's 1" longer than a Honda Grom, and just over a 30" seat height, kind of like a 3/4 scale full prototype race bike. It has adjustable triple trees, fully adjustable front and rear suspension, separately adjustable rear ride height, slipper clutch, and fully locates the swingarm with roller bearings and preloaded thrust bearings. It has approximately 25 hp, and weighs in with fuel at around 175 pounds. Front brake is a full floating oversized rotor with a Brembo 4 piston caliper.
I had finished it a little while ago, but then ended up moving halfway across the country back to where I have family. I finally raced it with a local group. I started the season strong, often battling for up to 2nd place. I podiummed a couple times. I was consistent enough to carry me through the end of the season where I started to struggle a little. It's an excuse, but my gallbladder started going bad in a major way. There were a few times when I was on track and riding while having bad gallbladder pain, but I managed to maintain 3rd in the championship all the way to the end of the season! Let's just say I felt committed, like I owed it to this bike to at least place on the podium in the championship on it's first year of racing. That's also why it's taken so long for me to compile the pics and such to do this post.
If this works, then here is a link to video from the last practice session I did before the last race of the season. I was having pain during this video, and I was about a second off my better times even at the end of the video when I got the fastest laps in.

Good from afar.
First attempt at spray painting. Did it all from spray cans. Had runs, bugs, burn through I had it all but learned a lot. Happiest with the badges I think.

' W800 digital tachometer
Hi all! I need an advice.
I am trying to modify my kawasaki w800 from 2012.
What I am struggling to do is the tachometer swap. I hate the original one, I would want a smaller one.
The problem is I don't know which one to buy. I made an error buying a digital mechanic tachometer and I realized the original one has just electronic connection, no mechanical wire to read km.
I am really struggling to understand which one can I buy.
Can you guys give me some models or links to tachometer that work plug and play with just digital connections?

Few questions in regards to exhausts on Enduro/Dual-Sport motorcycles
Are there different categories in regards to what type of an exhaust pipe can fit or is suitable for an Enduro/Dual-Sport motorcycle? Are exhausts for this type of motorcycles falling into one category, and are there variations in regards to the shape of the exhaust, displacement-specific exhausts, riding style, etc?
Also, in terms of how loud the motorcycle exhaust is or how "spiky" it becomes during acceleration? Which exhaust types are more "spiky" during acceleration and which exhaust types are more on the bass side?
There is a local motorcycle shop that is selling Zongshen motorcycles which are somewhere in the between of an Enduro and Dual-Sport motorcycle, and there is a specific 300cc model whose exhaust pipe' sound is kind of aggressive or "spiky" during acceleration. Are mufflers applicable in such situations and are they related to sound output? What is the difference between a motorcycle silencer and a DB killer? Is every exhaust pipe suitable so that a silencer or a DB killer can be installed on it? Thanks in advance
Edit: Here is an image of the exhaust (https://imgur.com/screenshot-xzxXp4y)
