Small Bike/Monkey Bike Supercharger

I don't know if anyone else has seen this, but it sounds like it would be fun.

I love stuff like this.

Supercharged Symba or Trail, anyone?

$700 for a bolt on kit is not expensive, IMO.

This is pretty cool but I can't help but wonder how an engine would hold up with the extra boost? My thinking is its not something you would want if you are at all concerned about long term reliability.

Probably able to handle just fine. As long as you are not exceeding valve train speed and everything still gets oil.

Superchargers seem to work well on the Ford Mustangs.
Adding a supercharger to a scooter or motorcycle is tougher
than adding one to a car because there is no existing external belt system
(no fan belt).
Something that has a primary drive belt, like a harley, would provide the least difficulty.

Wrong. Turbocharging or supercharging radically increases power and thus puts tremendous strain on pistons, rods, main and rod bearings, and crankshafts. Forced induction also has an effect like radically increasing compression, so self destruction due to pre-detonation is likely unless actual piston compression is reduced or knock sensors and sophisticated computerized engine controls are used.

Turbo or supercharging is viable in factory oem set ups because every part of the engine and it's management systems are engineered for them by the factory, and even then they haven't always had the same longevity as normally aspirated engines.

A kit like this, if it doesn't include beefier bottom end engine components etc, looks like a great way to increase performance for a very short time before the engine "grenades".

These are heavy duty little engines for their meager output. I would add an oil cooler for extra capacity and that is it.

These aren't engines that are tuned to the ragged edge of performance stock.

If you can upgrade fuel management. Check YouTube for turbo Groms. It has already been done, without the disastrous results.

The same thing was said about the Oldsmobile 350 V8 that GM converted to diesel some years ago.

The Grom hasn't been out long enough for anyone to wear out yet. If you want to halve the life of your motor with some boy-racer mods, go right ahead.

You realize that turbochargers and super chargers have been in widespread use since the 1920's, right? You can adjust boost pressure. Adding a turbo or supercharger doesn't automatically turn an engine into a Palestinian alarm clock.

And even if it did halve the life, after 20 years, you may not notice. My Cl90 still works after 40 and those look pretty hard.

Before World War Two, superchargers and turbochargers were allowed in MotoGP. After the war, they weren't. It's sort of like the turbine car at Indy. If they hadn't regulated them out of existence for racing, what would the street applications be like today?
I've already got a use in mind for this thing.

Wasn't the problem with that motor the head bolts being under-rated? The block itself was up to the task?
