I can possibly help folks or build an exhaust for the gp50/morini, and i can help with mounting systems as long as i know what bike its on... if anybody is looking to get one of these killers but is intimidated by the fab work involved. i can also build full ride ready cycles..... just putting it out their..
 
All I can say is, WOW! I'm totally jealous of you! All those bikes plus a Dax50. Man I'm speechless. I'd buy a show ticket just to walk around your place. Nice nice nice. What speeds has your bike gotten up to, an how much torque do have with that sprocket? I don't know if anybody knows yet, but do these engines have bushings or needle bearings?

Hey breno, how many teeth is your rear sprocket? What's the chain size you are using?

What's the max GPS speed you achieved? How is the torque?

Can it pull wheelies like the morini 9hp air cooled engine?

What do you think is the true horsepower on the clone engine? What do you think is the true maximum RPM on it?
 
Hey mate
56t with a #420 chain
Speed not sure if it's max but I was sitting on half throttle upright 6'5 tall 240lb at what felt near top speed at 80km/hr that was with a fella from work driving Beside me havin a chat/yell about my speed. Didn't bother to peg probly should have though.

It won't pull a wheelie just sitting there and gassin it but when I hit any bumps on the road under acceleration the wheel will lift and carry a meter or so without trying.

Taking off from the lights I generally always hole shot the cars by roughly 2-3 car lengths and hold that distance unless they punch it. I only have a single gear peddle side so I get about 5 peddles in and u can't keep up.

I'm still waiting on my tacho so I can't tell u the revs yet as I would just b guessing.
In terms of power well yeh seat of the pants tells me its roughly 2.5 to 3 times quicker than a 70cc ht
Hope that kinda answers ur questions.
I got my motor here in Australia though not from Dax but yeh it's still a clone so to speak.

Cheers
Breno

It's amazing to know that your acceleration is usually faster than that of a car. Nice torque I guess.

2.5 to 3 times quicker than a HT is quick. Is it reliable? Is it worth it? Did you have to do any hardware changes or replacements prior to running the engine to maintain reliability?
 
Mate I still haven't had to repair anything on the clone other than something I stuffed up.
I have sold 1 of my ht's and the other 1 is going at the end of the month. I have no inkling to bother with'em anymore.
In short yes its worth it.
Only thing is I have my bike setup like an on off switch its either fast or slow.
If I set it up in the middle I don't think it'd have the same punch.
It'll take a few rides to figure out how you want your clutch to work me I prefer the on off switch as I'm a self confessed adrenaline junkie.

They do have clutches. These clutches are centrifugal.

They have springs on them. Whenever the engine revs, it also rotates the clutch. When revving high enough the pull or outward force is strong enough to pull the clutch out and stretch the springs that hold them together.

There is also a plate that a clutch is enclosed in.

When the clutch stretches out, the pads on it touch the plate and the friction between the clutch and the plate is strong enough to rotate the sprocket.

was going to do a 99cc build...but I think i may go this route...way more hp, lighter, easier to work on, and just an hour with welder and its good to go. Just dont get the clutch system.
 
They don't need a clutch lever.
Centrifugal clutches automatically engage when you give it gas and rev up and disengage when you let go of the throttle.
