Little dirt bikes are so fun to hop up and cheap!! I have 1 boy of my own and 2 nephews to keep going so it’s pretty much nonstop working on one of the bikes!! Keep up the videos hope your feeling better.
I only wish I had kids to be able to please them like you John. Tnx so much for sharing your knowledge and can’t wait for your instructional video on maching calculations. Stay happy my friend
That bike was nasty after you worked your magic on it. I have practice porting junk cylinders and have so much respect for you cause that shit is hard to do, much love keep on keepin on
Badass little bike! Look forward to the next video I have a 193T I wanted to mess around and get built but idk that it would take it… thanks for another great video
It’s hard to believe that little bike doesn’t even have a foot peg brake to get kids used to having one, and I would put the one hand brake on the right hand side for the same reason. The clutch is on the left so…
Yeah I agree 100%... when I bought it I couldn't believe it had a kickstand and front break 🤦♂️... immediately ripped both off and tossed in my "parts for future projects bin" lol
Na that’s stupid putting the break over other side because then they will confuse front break with Clint h and go over bars lmao the foot break is a great idea but all bycicles mountain bikes road scooters operate this way universal world wide
You want the fresh charge directed at the carb wall ONLY . That way it pushes the old charge out. You may be trapping burnt gasses behind fresh fuel with transfers pointed to the exhaust side.
What you can try to make the engine even more snappy and revving higher its installing the aluminium 3 shoe clutch(you can lighten it to engage at higher rpm or change the springs) and one of the best upgrades to do if you have a lathe its lightening the flywheel.You can remove some of the fins and excess material my bike after removing every second fin and some materials spins to almost 1000 rpm more!
Damn man I have just got this bike for my 7 year old and wanna do something like this to it. I bought a big bore kit for it but haven’t installed it yet, would it be possible to port a big bore kit for more power or no? Thanks.
Do you do jobs? I have a old Suzuki that i have some sylinders for. There was a spesial one That i know know was named autisa 9hp alu cyl and it looks like one called big bore thats in steel just in othere places for the same bike. I bet that the cylindes have a lot i cud get out of them. But i dont have the tools. I cud port it. But the lade stuff. If you do i can send resize piston cylinder and top. Ore even a whole motor even. I know the shipping is high but i wood pay it.
Hey John any update on my saws. You had one for 18 months now. You don’t answer your phone and my 500i is already paid for. You still haven’t sent me a final invoice all I get out of you are sob stories I just want my saws
You have one of my 200t since January 2021. Which I sent you parts for it. Parts you said you couldn’t find. Then I paid for my 500i in December 2021 it’s almost September and still no saw. You never sent me the final invoice for that saw but I already sent you 1500 for. Then you have my other 200t since December too. You claim it’s done but I yet to see an invoice or a tracking number. You gave me this bs story that you sent them out and never wanted to give me a tracking. Then you claimed they got returned to you
No disrespect but you didn't rev it to max rpm like you did in the ported video. Need a loaded video to really see results. When the transfers have the divider ground away too much charge gets lost into exhaust so to grind the top both towards and away from exhaust makes charge go in both directions. So you exaggerate this problem. A transfer port should never be angled towards exhaust. If you have gains its from increased compression.
Thanks a lot dude for the detailed procedure porting this engine I didn't think there would be a vid. Definitely will be doing this to my pocket bike!

Very nice work man awesome transformation!!
That's so cool. I love you went all out on this. No half ass nothing.
I like this video... Thanks for the content dude.
I grew up the same way, and that's what got me into building custom everything
You’re absolutely awesome!!
Good to see ya john!!!

Thank you for stopping by and the kind words
Great Video !!
Thank you very much you helped me out a lot.
Bikes or saws or whatever, I always learn a little something here each time. Thank you for sharing the brain power.
Thank you for stopping by my brap brother

Sounds like my youth! I can relate😮💨
Nice job Dad!
have you tried cutting a 3rd tranfer ??? since its a reed case it could potentially work
Hope u are feeln better sir!

I have a couple of these bikes and I have been wanting to get the time to get a new engine to port. I would like to try a 372XP carb on it!
Awesome
Hi where would I go to get this sort of work done ? I got the same bike but it’s a 60cc version with same sort of head as urs
That's sick..I bet that thing would pull harder with a ktm50sx carb
Where can I find a crank for this engine
Why does it sound like someone getting piped down in back ground the entire video 😂

Thank you bud for the info ..
What is the seat height
What you charge me to do mine?
How strange the cylinder looks like a homelite cylinder how cool
Is it possible to send you something to port?
You should put a better exhaust next 👍👍
Damn man I have just got this bike for my 7 year old and wanna do something like this to it. I bought a big bore kit for it but haven’t installed it yet, would it be possible to port a big bore kit for more power or no? Thanks.
If you haven't installed it yet or if you have any haven't ported it they go hand in hand. It's definitely worth doing both at the same time
Any chance you are selling head and piston kits of these. I'll buy 2 straight up
Me to
how long is the crnak and bearings going to hold?
Do you do porting for people, if so how much would it cost to do what you did?
Do you do jobs? I have a old Suzuki that i have some sylinders for. There was a spesial one That i know know was named autisa 9hp alu cyl and it looks like one called big bore thats in steel just in othere places for the same bike.

Can I drill holes in my con-rod?
I should really read previous comments lol 😂
I'll pay you to do both my kids engines
stock carb?
Yes
Have a seat. Take a load off. Relax. The pacing back and forth in the voice over was alot lol
👊👊😂
First!!!

HEY how come you have a shitty finish should be a 32 finish by Rookie.

When the transfers have the divider ground away too much charge gets lost into exhaust so to grind the top both towards and away from exhaust makes charge go in both directions.

Bro need to get his fix before filming his voice and hands be shaking
