Default Re: what did you do to your motorized bicycle today?

I know the feeling... just took on a new project to build up but wanted to do some last touch ups to my main ride so 2 weekends ago I had enough time to get the engine out and do some final welds before taking it all the way apart for paint... then I notice there's a crack in the frame... go to weld it shut and I'll be back on track with that I'm gonna do but blow a hole in the frame tube while welding. I cut out that section of frame and see how thin this tubing really is so next thing I'm cutting out the bottom tube, bending a new tube, and all set up and ready to weld it in but I'm out of argon for my tig setup, don't want to use the mig on it, and my sawzall is at home so I cant really get a nice clean cut to splice in the new bottom tube so now that bike is still apart awaiting enough free time for me to finish these repairs and do the painting I originally planned to do.
Being dead in the water on that one I began taking apart the stingray I got a few weeks ago to strip it down to bare metal, beef up the frame in a few places, and get it repainted. Some of the parts were a lot rustyer than I thought so ive been wire brushing all the parts with rust on them... like all the chrome parts, then powder coating these parts as I get them rust free and ready. The frame its self and the fork tubes will just get regular paint since my powder coat oven is way too small. I'm not in a hurry to get this one done since I want it to be setup just the way I planned with the billet mounts, solid layback seat post and cloud9 seat, ape hanger bars, and I may build up a girder type front end for a smoother ride but excellent handling... I want this one to be able to ride safely at 45+ mph as well so I will spend the extra time and effort on the frame before I start thinking about installing the engine, wheels, forks, etc.
I am also really tempted to put my old engine into my son's bike just to get me back up on 2 wheels sooner while I'm doing the repairs to the mountainbike frame since his bike has the same frame and I can just transfer my parts to his frame pretty quickly... of course, if I did that it would be about when he got interested in the bike again and want it back...

Just like chocolate one motor-bicycle is never enough.
I know exactly what you mean....

I have 6 bikes and a couple more on the back burner, I know at some point Ill have to stop and just pick the ones I want to tinker with and make improvements to over time since none of my bikes are fancy builds and can all use a few upgrades over time.

Best wishes on your projects IWw

"Just like chocolate one motor-bicycle is never enough."

The finest and most fundamental mathematical rule of cycles. Where the ideal number of cycles to own is described as the equation: N+1; where N = the number of cycles you currently own. I have pretty much reached capacity in my garage, and yet I can always seem to find room somewhere for one more project, and I'm perpetually only one bad idea away from my next bike. My bad idea du jour is an HF79cc and I'm already thinking about colour scheme which means bad news for my wallet...

LOL....... I have two of the HF79cc new in the box that I plan to use for some type of a build in the future, ma6 end up on something I build for the grandkids down the road but Id like to use at least one of them for a bike build Ive had in mind for a good while.

Yes an overactive imagination can be a curse sometimes, but then on the other hand I can think of worse things to be cursed with

Slow day at the shop today... Everyone in San Antonio is at Fiesta Downtown and nobody's getting their cars fixed... I just can't understand why people would rather go to Fiesta instead of getting their cars fixed... anyway, all that free time means I get to tinker with My projects some...

Today I cut out the bad section of frame on my mountain bike and bent a new lower tube for it, the bend isn't too drastic, but should give me at least another inch of badly needed engine clearance... Before, my engine sat in there so tight that I had to pull the engine to remove the carb or even to remove a spark plug... I'm trying to get enough room that I can pull the head or the carb... or both with the engine still mounted in the frame...

Here's the bike with the bottom tube cut out... It's suprisingly strong enough to hold me without flexing like this, but there's no way I'd even pedal ride it like this...



Here's the bad section of frame that motivated me to do this in the first place...


And here's a trial fit of what the new tube will look like, I tried it with the bend closer to the bottom but liked the way it looks with the bend higher up, and this way offers the most room for the engine when I'm ready to put it back in... I'm gonna have LOTS of welding to do first tho...



Oops... almost forgot this one... This is just to show just how thin the wall thickness of these cheap Roadmaster Mountainbike frames really are... No wonder I blew a hole in the metal when trying to weld up the crack... and I had my amps and speed set really low too... I didn't measure the wall thickness, but if my eye calibration is still good enough, I'd say it's about .040" thick at best... I'll measure it tomorrow just to see if my eye calibration is as good as it used to be. The new tube has a .080" wall thickness so if anything breaks again, it won't be the bottom tube...




I've also been doing some of the more quick and easy stuff for the Stingray build like ordering the billet mount setup for the engine as well as the Manic hub & sprocket. I still need to get a seat for it and want to get a set of 14" ape hangers since it's a chopper after all. I'll also reenforce the welds in all the critical areas on this frame too since I have a really strong suspicion that it has the same thin wall tubing the roadmaster has... The lower tube of the Roadmaster is the exact same size and cross section as the Stingray bottom tube as well... More on that one as I go too...

Yer right Davezilla,after building about 10 or 12 of the OCC chopper bikes, I decided the frame is way too thin to build a really safe motorized bicycle and wont build on them again. NOW, The Jesse James chopper, By Huffy, Has a heavier frame and makes a real nice build. although I've only done one of those.

I kinda figured that when I got that tube cut off the mountainbike and saw it was exactly the same as the OCC Stingray's bottom tube... I do see some doublers and gussets in that bike's near future before it's put on the road...

ok so why are you having a hard time starting your jet engine? could it be because of the ignition system? did you remember to hold down the button on the opposite side of the fuel on line? if there is air in the float bowl you have to push it quite a few times to purge the air out of the float bowl this is the big reason ppl keep coming back to me for no start problems
