Exhaust Insides of exhaust are gone how do I replace?

Lol you must really have had a hard time. I've seen a bunch of your posts/threads around talking about this. Lol. I feel your pain man. My exhaust studs have held up fine but there's always something wrong with these things. Unless you dump hundreds of dollars into it to replace every crappy piece which kinda defeats the point of these things. If you're gonna spend that much money you might as well buy a production bike/scooter.

I think it is wise to also just slam a generic lawnmower muffler on there and take the issue of weight ruining the exhaust studs over time. The entire stock muffler is designed to fail. The insides falling out can maybe be prevented with red locktite, but the overall stress on the exhaust studs will, at the very least, continue to work the muffler loose and, at worst, destroy the studs/ threads. I had experienced more problems with the exhaust than any other system on the motorbike.

it's fine if you use the supplied clamp and don't overtighten it. nobody uses the clamp so a lot of people have problems

Got my kit from bikeberry.com and it didn't come with a clamp for the exhaust.

I have not experienced any of these issues that you describe.

Not true.
The enjoyment of these bikes comes from the fact that they can be built to a sub 40 kilo (90lb) weight and consequently, they still handle in a surprisingly similar manner to that of a conventional bicycle.

Secondly, you can get these bikes into national parks, because they can be made quiet enough to fly under the radar, where motorbikes are banned by the forestry and wildlife department.

My bike (just the bike itself) has had around $5,000 thrown at it, and i wouldn't trade it for a scooter or production bike.

I like my motorized bicycle because I can take it places I can't take a motorcycle. Have you ever tried to lift a harley over a fence?

I agree.
Have you ever tried to life a relatively light weight 100 kilo (220lb) 2-stroke dirt bike over a fence or large tree blocking a goat track or trail.
It's hard enough with 3 people, let alone trying to do it by yourself.

My motorised bicycle and trailer has taken me to many places that would have been impossible to gain access on a conventional dirt bike, especially if using normal routes patrolled by wildlife & Parks rangers.

Edward:

I am convinced that the future of transit is two wheels. I have been a bicycle rider and racer all my life so I know what the potential is.

Too much of our mindset is framed by what I call "carlove". The dominance of the car/truck road infrastructure dominates every decision and plan that people conceive and squashes real creativity and sensible economics. For instance, small motorcycles usually start at 250cc and almost all motorcycle riders describe this as woefully "underpowered". This is why so few motorcycle enthusiasts actually commute via their motorcycle. For them it is all about culture and being seen. Big cars, big motors, big noise- it's all a part of the American mythology.

Something bad happened to me yesterday: while on the motorbike on a highway with very light traffic, I was "coal rolled" by a gigantic diesel truck. That is to say this guy passed me (I was going 25-28 mph) and he edged over into my lane and let loose a huge cloud of black smoke that engulfed me. F*cking egregious! I am searching for this guy as we speak. I consider it assault. This kind of thing is all a part of the mindset.

Don't misread my posts about the motorbike! I am just giving honest reports about my learning experience hoping that it can be a help to others. Each car commute to work costs me roughly $5. On motorbike #1, I commuted 31 times;on motorbike #2 14 times. Counting all the other errands and trips near and far, this thing has already paid for itself! I have worked very hard and I continue to learn. I have threadlocker and JB Weld on hand at all times. I carry a small 10mm combination wrench in my rear back pocket.

I can weld - I used to get paid well to do it!- but I don't have a welder and I really can't afford one (or a Ducati Scrambler!). Man, I can think of ten ways to make something much better and much more reliable than the stock muffler. But it requires good welding. In the meantime, my $12 muffler fix has performed flawlessly. It's actually pretty quiet at cruise speed!

I am proud to say that my MotoBeast has jumped up to a very high level of reliability. It can be done.

I'd really like to build my own motorcycle in the Spring, but that requires a higher level of knowledge. I know very little about motorcycle frames or where to procure one. In my mind, I'd like to slap a ~200cc engine on there with a simple gearbox and electric system. Then I'd like to get it all titled and registered, insure it, yeah that is a great idea!

Thanks for the note and the empathy! If there is anything I can do to help, drop me a note.

Sorry it's taken so long to update you guys. I took your advice about the steel wool. I got ones with the thickest strands to avoid them catching fire. Haven't had a problem with that. I shoved a pipe through the middle of them to make it so they wouldn't be too restrictive. I then cut a small notch in the exhaust and used a hose clamp on the inside of the pipe (putting pressure outwards instead of clamping inward) with a screen over it to keep everything in. The pressure of the clamp has proved to be enough to keep everything from moving even over rough terrain. It's not quiet by any means but it's not as loud as originally. maybe 30-40% quieter. That's anecdotal though. I haven't actually measured db levels. If you guys care I will though.

Unless you're like me and you like to tinker, and can afford to.
