GY6 50cc SINGLE BOOST BOTTLE KIT

I didnt really notice he was also talking about a rotary valve design engine. What kind of scooter is using a rotary valve design? My friend owns a few Kawasaki Ke100, and 250s that use that design. Ive never seen a scooter with one. There isnt room between the carb and the side of the block for any boost nipple Id think. Rotary valve is a neat engine style. There are 2 and 4 stroke designs. I work on a lot of rotaries which are another cool engine.
I think a poppet style might be using pistons/ valves driven by cam.

I'm not sure what a poppet valve engine is.

Poppet valve or mushroom valve used in 4-stroke engines. Rotary valve are used in most 2-strokes.

..poppet....valve...

Ah... 4t's... That's what High Rise manifolds do. The extra tunnel length provides "storage" of un used mix. Experimenting with different manifold lengths will give a boost to low end torque. Too long will destroy top end.
This will work MUCH better than a bottle hung in the works. There is not enough time for (intake duration) the bottle to suck up anything (intake closing) on a 4t

Most 2 strokes scooters are reed valve, some older vespas are rotary valve and some german ones Ive seen, but most are reed. How many rotary valve motorcycles or scooters were made? or are still made for that matter I wonder. Our scooters are reed cage at any rate.
In Australia we have a few makers that used them in the 80s, but as the 90s came about it faded as theres no easy way to repair that valve/disc and back fires are devastating to them. I know kawasaki used them for their KE series but not many others followed. Its an easy thing to mod but once you go to far timing is done for.

Yes, high rise plus ram air! So, in short this advertised boost bottle thing is nothing more than an intimidation to those who are ignorant and a laugh to those who know? Hmmm....













how 'bout this bottle?

Nice a plastic NOS bottle strapped to a scoot, hahaha!

I have one brother that is a believer in NOS. He adds it to every bike he rides. I think it is a cheat. I'd rather run a blower/turbo for better results. Blowers don't run empty after 40 seconds.

I will strap my girlfriend my scooter and she will last more than 40 seconds and do better job then blower or turbo.............

Who would have ever thought a girl would be better than a bottle...

True that my neighbor has a computer fan he uses in the manafold for a power boost.
