Joke aside, put at least a front suspension and disc brake.
Front suspension has been added, I'll deal with disc brakes on the next build!

Just a cheap Chinese 50cc, part of the popular kit sold on eBay. I have a 66cc that I will modify heavily before installing on the next build!

Hate to rain on your parade but I have since modified it to a pneumatic engine fueled by a Scuba tank and 400 psi from my fridge compressor... :D But actually, I am experimenting with air engines again and I want to build an air bike... had a dream last night that I made a "hybrid" gas engine/compressed air engine bike, and it was quite satisfying. But, in no way shape or form does that coincide with my feelings for hybrid cannons... :wink:

On the topic of those doodads, I wouldn't bother touching the carby, not much gain there really. Whip the head off, tidy up the ports with a dremel, chuck on a banana pipe if you're really keen, then drop a few teeth on the rear sprocket if it accelerates well. Should up the top speed. Then buy a motorbike because motorbikes are awesome
All things I am considering on my next bike! Now that I have a machine shop, I want to CNC a high comp head as well, and I plan on chopping off the back end of the frame and adding a rear suspension 8) should be a pretty sweet ride. Taking inspiration from the holy grail of motorbikes.

Couple of CF SCUBA tanks, that would be an interesting project actually. Not as power dense as a hybrid, of course ;) but if you used a turbine instead of a reciprocating engine it would sound pretty neat.

Ah yes, the Motoped... I hadn't discovered them yet at the time!

Since the last time I posted, I finished modifying that 66cc and I am currently running it on my old bike frame. Man, does this thing RIP compared to my old 50. Some things I modified on it:
1. high compression (from 90 to about 120 psi)
2. intake porting
3. exhaust porting
4. adjusted transfer port angle for better mixing/combustion
5. custom intake manifold (I welded something!! something useful!! lol) and KTM carb
6. straight pipe exhaust because I busted the mounting bolts :lol:
7. upgraded some hardware and bearings
8. trimmed piston skirt for larger intake opening

I'm also nearly done with my full suspension frame. I machined the entire swing arm for the rear suspension and I just need to machine a couple more parts to finish it up.

I'll try to post a couple pictures and videos soon so y'all can see what I've been up to in my absence!

Nice bike too lab, what have you done with it?

Just about everything :D
Cut it in half in order to mount WP front and rear suspension, made a new exhaust from stainless steel, simplified the electrical system, tuned the carbs for more powah, mounted two 60 watt led bars as a front light, reinforced the frame to make it more crash proof, etc :P
