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... 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...

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.

Disagree!

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.

I really want to do this for an 8.8cm Flak 37!

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
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!

There's no poll but dogs or cats? I'm a dog person

A useful skill for building devices containing pressurized fuel air mixtures... all hope is not lost

I say...

Sweet! I need to get myself a job like that

Haven't been accelerating random stuff from my workshop lately, built myself a new motorcycle however.

Labtec back, Mark.f online (I see you boy) now we just need Poland and SB15 back! We'll all be able to bully GF into building a hybrid.

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

Always here. Always watching.

im trying desperatly to find some sdr 26 2.5 inch pipe i have looked hi and low not one-lead ,even called tons of stores

can anyone help me? ill pay shipping and everything thankz guyz

For a spud gun or an actual drainage job ?

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

Just about everything
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

spudgun to launch soda cans, i only need like 4 feet of it, i cant find it anywhere ,

You can't use regular PVC ?
