Motorized Bike ways to Increase port duration and Working on the Cylinder 

Thanks brother

Wow man that’s actually great information might try it I was only going to do it on the backside to help it have metal to metal contact in the case itself

@@keeganhache6667 Have you ever had any coils go bad after like 1 year ? I'm not sure the exact number but seen several videos & people on forums mentioning that their coil went bad after only 6 months or a yr. Then mention upgrading from the 3 wire to a 2 wire, etc...Saying the 3 wire is junk & that's why it only lasted 6 mos... I got the 3 wire coil & it's 3 yrs old so.....I rarely use my kill button, I heard that makes em go bad but dunno how much truth there is to it. Supposedly the kill switch shorts it out to stop the spark & makes heat but the coil is already hot from being mounted to the engine. 🤷‍♂️

@@keeganhache6667 OH yeah had I been thinking I would have looked over the ignition coil/cdi box, to see how well it was sealed up & expoxy coat it, if it didn't look well sealed.

Can you run piston port with a boost port?

@@justanothermotorizedbikech5138yes you can

Yup it’s always good to sand down edges after porting the cylinder

Flow case porting is bum information your compressing gasses not liquid. If you have a step a impedance in the intake port yea that's helpful. Or a impedance in exhaust exit sure. Butt a step in a out flow say like tranfers to cyl your doing nothing but lowering crank case pressure wasting time and effort. You won't find a single video showing power gains factual power gains on case porting with the exception of a case Reed motor with a inflow impedance. Just stating proven facts

Thanks

It’s worth it man

Thanks Kevin

No problem

Yessir how’ve you been? Been watching a crap ton of your videos man they really come in handy when ever somebody said your info is wrong I show them the 60 mph video of you flying lol

@@keeganhache6667 only doing NHRA prostock motorcycle engines. Kinda tired of them nowadays. Good job on making vids. Tip on window making you can drill your 4 corners and have perfect radius,s. Filter out the bum information in the comments. All that directional case port matching and angled comments are comical. Especially vids saying crank rotation. Case flow port matching. Super simple point people miss your compressing gasses not liquid. Keep doing exactly what your doing you'll find out first hand who's information is factual. I don't write great so don't take my responses wrong. Basically don't fall for bum information. I have factual real world tested litterly everything. Keep up the good work

Great tip on the window definitely will give it a shot next time around I’ve always used this method and the chinadolls keep up with my Minnerelli so it’s saying something I can link your channel in the description if y’a don’t mind take care brother

@@keeganhache6667 one more simple tip. Mark your tranfer opening line around to the exhaust port. If you keep most of your changes above the tranfer opening in your exhaust port you have less ring bulg. Hence the mushroom shape. Never have I snagged a ring hundreds of cyls ran

@@keeganhache6667 it's definitely cool. Big credit to you your applying your learned skills with YOUR HANDS. ANYONE can bolt on a pre maid cyl and act like they actually improved something. BUT YOU CAN TAKE 💯 % CREDIT FOR HOW YOUR ENGINE PERFORMS. SIMPLY YOU TOOK A 🍋 AND MADE LEMONADE. you made something out of nothing. Do minarelli and other pre made cyls run good answers ehhh yea. But where is the lesson in that. Keep up the good work.

Good thing is pistons are cheap! Remember there is a high hole and low hole styles

Nope only do that in the Exhaust this is not a fuel injected car engine the intake port needs to be textured

No see the issue on a 2 stroke motor is if there’s to much port area at low rpm’s the motor can’t flow the gases properly it’s like putting a 4inch exhaust on a Honda civic it can’t use the velocity you need a smaller port at low rpm

@@keeganhache6667 Thanks for clearing that up.

I saw videos it’s like older dudes lol

The 212cc still made in China 😜
