thanks idol for your tutorial video,

Hey Frank, I have one of these engines with a big exhaust on. It runs quite nice and I’ve just bought a reed valve kit, do you have any suggestions on how to port it or do these engines not preform well with a reed conversion??

[@azizahjalis7762]

Hi frank. Could you please tell us how high do you raise the exhaust port? Thanks

How big power engine after full modif racing

[@madmaxsdog8040]

I used to tune and modify racing 2 strokes and port matching does make a difference, not very much at maximum power when the engine is devouring air, for example at 9000 rpm the air goes through the ENTIRE ENGINE in 0.0066 of a second, ( 60 seconds divided by 9000 rpm) the port matching helps just before the powerband and with the throttle pickup, when the airflow is less. My engines would go 12000, in this case the air goes through the entire engine in 0.005 of a second. (60 seconds divided by 12000)

Hello Sir, Got a similar 63cc Kasei 2 stroke but it is hard to turn and thinking its the compression release problem, where on the engine would I find it to fix it, close to the pull string or close to the exhaust on this 63cc, Thank you in advance

[@frankg3278]

Never had that problem before. Is it new?

[@JasonOlbrys]

Hi could you tell me where you got that engine stand for the 63cc thank you.

[@frankg3278]

I made it…

[@JasonOlbrys]

@@frankg3278 can you make me one. Ive been looking for something like this so I can run the motor in a frame of a bicycle and use a transmission for it.

Here in the USA state of Rhode Island mate. Can you please give us a name of this little fellow. I’d love to pick one up here if able. ⚙️🚲⚙️💥

[@frankg3278]

I do actually travel to Boston from time to time

[@ILLEGALLLLRacingGERMANY]

a 80cc can be hit with a good combustion chamber tuning fine tuning 2,2-2,5 mm filed away from all sites from the combustion chamber you likes 3mm from all sites in carb enter from cylinder self you can hit still more its woulds works likes a tuned scooter with higher gear PLUS mountain up no problemes more enough power

[@mflbikes1870]

is this a 44mm bore or 50

[@frankg3278]

48

[@michaeljosop9871]

Type of engine?

[@zior8001]

Kasei 63

[@y.g6947]

What brand motor is this

[@frankg3278]

Huasheng/Kasei 1e48f 63cc. Same engine used on the Maf/Evo/Uberscoot

[@axiomloves21]

Do you guys recommend this 63cc over a cy460? I want a user friendly plug n play engine for my uberscoot, thanks lads

[@frankg3278]

@@axiomloves21 I'd go with the 460 for simplicity. The 63 is great but it takes some work.
