Default New Project

I'm just starting to gather parts for a new project I'm starting on. It's going to be a bike similar to the ones msrfan builds, on an old Columbia frame with a Briggs 5hp squeezed in with moped front fork, hubs, and controls. I haven't started any actual work yet, but I picked up the frame and a parts moped yesterday (which I just realized probably won't work). It's gonna have a torque converter and probably rope start (not recoil) and should hopefully go really fast. I think I'm gonna make it look kind of like a dirt bike with pointed bobbed fenders and a loud exhaust. I know I don't want to use the stock carb on the 5 horse, so what carbs are a good fit for a stock engine? And is there an off the shelf intake for a motor mounted at about 45 degrees? I'll post some pictures as I start building it, hopefully soon.

I really like the PZ19 carb for larger 4 strokes. It will require a custom intake, pretty much no matter what.

Hey Mike, how about some photos of the parts you've got so far?

Let's see if this works. Here's a link to my photobucket album that has the pictures:
<div style="width:480px;text-align:right;"><embed width="480" height="360" src="http://pic2.pbsrc.com/flash/rss_slideshow.swf" flashvars="rssFeed=http%3A%2F%2Ffeed1045.photobuck et.com%2Falbums%2Fb458%2FMikeStroz%2FMobile%2520Up loads%2Ffeed.rss" type="application/x-shockwave-flash" wmode="transparent" /><a href="javascript:void(0);" target="_blank"><img src="http://pic.photobucket.com/share/icons/embed/btn_geturs.gif" style="border:none;" /></a><a href="http://s1045.photobucket.com/user/MikeStroz/library/Mobile%20Uploads" target="_blank"><img src="http://pic.photobucket.com/share/icons/embed/btn_viewall.gif" style="border:none;" alt="MikeStroz's Mobile Uploads album on Photobucket" /></a></div>

The frame is a 60's Columbia (unknown model), the fenders I cut down I think came off a Western Flyer bike from the 40's, the engine came off (I was told) a sidewalk sweeper, and is in almost perfect shape, excellent compression and spark, started on the first pull. I got it because it had a gear reduction unit and I knew I needed those holes to mount the torque converter, but what I didn't realize is that it had a spline shaft instead of the normal one with a keyway... I think I need to find either another motor and swap the crankcase cover, or a different crank... And the Motobecane moped is what the wheel hubs, fork, handlebars, controls, and maybe some electrics are coming off of. Not off of that exact one, since I actually ride that around, but basically the same model and same pieces. Any suggestions for the gas tank? I haven't found one I really liked yet.

I don't think I pasted the right thing... Maybe this?

Well, that does work, but it takes us to your album. If you go to the picture and click "share", "get links", and then copy the url that says IMG. Paste that here, rinse, repeat.

Just got an old pair of Atom moped hubs off a Motobecane. The guy I got them from has the rest of the pieces I need, but he has to dig them out of a huge pile of parts before I can get them. The hubs are in great shape and just need some cleaning and they fit in the frame like it was meant to be. I've brought them to 2 bike shops so far to have the rims laced on, but they both refused for "liability reasons" even though I told them the wheels are for a cruiser bike with no engine... So now I have to find someone to build those wheels for me... (I tried before and it didn't turn out all that well)

You will need to source thick diameter spokes for those hubs, I found out when we started putting my project together.

Anyone know a place in MA or NH where I can get these wheels laced up? I have the rims and hubs but no spokes yet. I was thinking of trying a moped shop but I doubt they have the right size spokes for a 26" wheel. I did source a front fork that I can use, but the threads stripped out so I have a new steering tube thing on order (the thing the fork pivots on) as well as a nice set of controls that'll bolt right up. I'm thinking now that I might leave the thing without a motor for a little bit, just ride it around as a bike over the summer and throw the engine on over the winter.
