I've been looking around lately for a way to get a longer seat with more padding on my 26" cruiser. I came across exactly what I want to do here:

I really love the way Alain has mounted the seat, and I was wondering if anyone has some tips on how to replicate this?

I'm 6'4" and 200lbs, so I'm also looking for something strong, lol.

I was wondering what it was, but now I know.
Is this a good alternative to disc brakes? How about reliability, servicing, parts?
Thanks.

Looking to replace my stock square clutch pucks in my 66cc HT with something a little more durable. From asking about, it looks like Dean at Pipelyne only has the round pucks, and others who can make them are not doing so at this time.

So, time to roll my own. Does anyone have a good source for a small amount of the high friction material for these things?

I checked McMaster-Carr and I think the stuff in the strips would be easy enough to work with and cheap, the semi-metallic high-strength strips. The coefficient of friction is only a little lower than the high friction sheet material and the max operating temp is a little lower, but they do take a lot less pressure.

Anyone think that would work? I found a post from a guy on a forum that uses that material to make brake pads for his ATV with good success, and we all know you can believe everything you read on the internet! The high friction sheet material would probably work better, but since it is 9x more expensive and probably harder to work with since I only have hand tools available, I would certainly prefer the strips... ]]> Hubs, Gearboxes and Sprockets maurtis http://motorbicycling.com/showthread.php?t=39346 brand new member http://motorbicycling.com/showthread.php?t=39345&goto=newpost Wed, 16 May 2012 12:29:49 GMT Hey all!! been following this site for a while now, stock piling as much knowledge as I can.

Is there some sort of liquid gasket material that won't melt off; and still allow me to remove the exhaust pipe somewhat easily?

About 3mths ago I purchased a Huffy Deluxe Cruiser with the sole intentions of cruising the neighborhood. I ran across this forum not long after buying bike and thought, 'man I gotta get me a motor'. I researched the site throughly and ended up getting an 80cc bgf off ebay. After a month of working on it when I could, my MB is up and running, NOTHING like the feeling I had this past sunday when the motor turned for the first time. I dont claim to be the handiest with the tools but I was able to get ALL INFO I needed right here on this site, just took research. THANKS!!
Its a pretty basic build with only upgrade so far being a manic sprocket adapter. Felt like this was the best first upgrade.
I will add some pics later but like I said, pretty basic but sure is a BLAST. Thanks for ALL yalls info!!

On another note sorry if there isn't enough information I don't know much about anything mechanical.

So I this guy was getting rid of this bicycle and was going to leave it by the dumpster so I decided to pick it up. He said the only problem was the carb needed to be cleaned out. So I brought it home checked it out and immediately tried to start it up and as I expected it didn't start up so the next go around I left the choke on and it started running. To my horror however the RPM's went through the roof it started to vibrate and I thought the whole bike was about to fly apart. So I took the choke off and instead of idling it just died out. So I took it back to my garage and tore the carb down expecting it to be along process because I have never done it before, but have heard carb's have a lot of small parts and are tedious to work on. Well I tore it down and cleaned it with some wd-40 and tried it again but to my dismay the same problem came along. I've read through some posts and possible things could be air leak somewhere, possibly need to clean out the inlet that lets the gas mixture in.

If there are anymore suggestions please let me know.
It does work on 1/2 choke as well. I cannot control the rpm's though. I checked the throttle cable and it moves but while I was looking into the carb the needle doesn't come out of the hole all the way(not sure if it is supposed to). Also when I took it out and ran it with the choke on the exhaust started to smoke( I know that is bad for it).

Thank you in advance.
Sorry for my ignorance. ]]> Motorized Bicycle General Discussion Pickens http://motorbicycling.com/showthread.php?t=39341 Looking for a wide pedal crank http://motorbicycling.com/showthread.php?t=39340&goto=newpost Wed, 16 May 2012 05:19:16 GMT My 4 stroke kit didn't come with the wide crank, so I need to buy one separately. I have a Felt Twin with an original one piece crank, I think that is the "American" type? I think the one on Bike Berry you have to buy an adapter for the kit, because it's a European size. I'm a little confused on what is going to fit my bike, what I need to buy, and where which is the best one to buy.

Any Suggestions? ]]> Wheels, Brakes and Suspension SD moto man http://motorbicycling.com/showthread.php?t=39340 Motorized Felt build pics http://motorbicycling.com/showthread.php?t=39339&goto=newpost Wed, 16 May 2012 05:07:44 GMT I've been doing some builds with Felts and I used a Giant Simple recently also. They make great looking bikes...

I really like using the Pirate Cycles sprocket hub adapter. I also recently bought a KW machine works machined aluminum sprocket hub for my nexus hub on my MP. Ken does superb work. I have his offset engine mounts on a few of my bikes also.
