Have a burner cylinder to practice on but for sure gonna start with the basics on this vid for all my new gear coming in. Thanks for posting. I know I had watched it before but remember it while I was checking out your IG. YOU DO GOOD SHITE!!! Keep it up Brudduh
Informative I found widening the exhaust port on the inside and ramping the piston plus I took 1mm off the intake side of the piston kept bottom end power and increased top end drastically
@@2strokerc5782 yeah on the 45 timing duration has plenty of room to play. Happy to see you doing this on your own and experimenting. Keep up the good work sir.
So I did all this to my g23 and wow huge power gain. plus the exhaust port was gummed up so it was like half the size. Was probably my problem the hole time but. Wow
DDM CHOCLATE MINTS FTW! I remember when they first came out with those.. time flys, been pedding since 1995, just bought a nice barely used XPED and just got a stuffed crank GP290 for it
Hey perkins. I used to ride with you and zcat. I have a 26cc marine engine. I want to port it out for more performance. But i never done a port job before. How should i do so?
What do u use to stop ur dremeled tools from filling up with the engine material & becoming useless? Any type of oil on your tools or do I just replace them? Tx!
What do you recommend for a porting tool? Im using a cheap one an want to step it up any advice is appreciated i did some porting and so far im pretty happy with everything but my dremmel kinda sucks and it doesn’t fit the bits i got...
How do you calculate how much material to remove from the exhaust port as intake to increase duration? You just go right to it ? You have to figure out what your timing is first wit a assembled engine with squish set to where you want it , then put a degree wheel on it with pointer , find TDC then accurately remove material wile measuring degrees
85Randall I made this video as an introduction.. just starting out with your first time you don't really need to worry about all that. I do have a squish meter and degree wheeel.. but honestly if someone already has those tools or know they are required, they don't need instruction from me.
Port "time" is probably the most important factor for building the engine to your needs, but it is "port time area" that also includes the width and corner radius's of the port. There are some old calculations you can do by hand to figure them out, and there is aging and going extinct 2-stroke porting software, like TSR, (Turner now retired), that calculates port time area for any given application. None of it seems to be perfect to me, but they seem to work better than "trial and error" as far as time invested. Doug @ ESP
Here is something you might like to know. From a program called "degree it" in my TSR software, I discovered that one degree of added duration at the exhaust and the intake is really really close to .005" of material. So if you want to add 3 degrees of duration to those ports, you know .015" will be very close, closer than you can measure with a degree wheel for the slight existing error repeatably.
Nitrow Boxhead bounty it changes timing, the more fuel you allow in per stroke lengthens the time it take to process. . that in combination with a 100+ lb. load creates a low end lag.. I usually try to find a healthy medium with gopeds and mostly just widen the intake with a minor timing change.
I understand that a richer mixture burns slower. So would more air/oxygen/n2o help with the low end lag if time of processing is lengthened with more fuel? with the same piston size?
Nitrow Boxhead bounty yes I see where your going, this tutorial is for non reed engines... if you had a reed valve to regulate intake timing your theory would prove effective.
well i just bought a t maxx.. 3.3. so i was thinking maybe bying a stock traxxas 3.3 motor for a back up cuzz there on sale and trying my luck at trying to bore it out a to give it some more power..
Thanks I'll be on the lookout for more of your porting videos for ideas 😊

Thanks for the comment. What are you using this engine for?

Do a g320 port job please
I wish you could make a full video of what you just explained. That would be awesome. Good info though thanks.
David T you mean while I'm doing the work? That's a good idea
South Florida RC kings Yeah that would be awesome. I haven't seen any videos on TH-cam of that done yet. especially on a goped engine.

Cool, you have DDM and TGN stickers in your vid; both got me started in this business 15 years ago. The DDM candy is tasty, isn't it? :)

Does making the window on the Reed piston bigger make more horsepower than not
What else would you recommend doing to the transfers? Just cut them a little deeper?
That’s pretty cool man 👌✅👍🤔
Hey perkins. I used to ride with you and zcat. I have a 26cc marine engine. I want to port it out for more performance. But i never done a port job before. How should i do so?
Very carefully
need some more videos/tips how to port more
If I only widen out the sides of the intake/exhaust & not the top/bottom, does it still effect the timing or just allow more fuel in/exhaust leaving?
Would those work for a stock GSR 40 motor? I just want a little extra outta it. Also Do you have any kits available for it or nah?

controlling the speed correctly prevents this. large bits spin slow, small bits spin fast. I never use anything on my bits, just dry.
I learned if you coat your bit with wax it will not clump up
Hi I want to port my 2.5 trx engine what ports do I need to enlarge? You got me wanting to try great vid bro
bro do you got another video.. i wannna learn how to make a stroker motor.. what tools are needed .. im super new but build race cars
Grandpaganja G what kind of stroker exactly, and what engine?
What do you recommend for a porting tool? Im using a cheap one an want to step it up any advice is appreciated i did some porting and so far im pretty happy with everything but my dremmel kinda sucks and it doesn’t fit the bits i got...
4300 series dremel and metal wand is my tool of choice.
@@Perkins.porting rite on thanks for getting back to me brotha appreciate it! 👊🏼
@@JesseK410 Search tungsten bit set on fleabay They are around $12 a set you need the 1/8” shaft version for dremel.

I understand why he is saying you don't need to worry about all that now. No beginner is going to a calipers and what not to measure thousandths
thanks 4 the tips going 2 try real soon I follow your Instagram I like your work I need 1 of those stickers perkins portig;))))))))
Joshua Lara , your welcome. . stickers are free to customers.
How do u change the timing once you have ported it that's where I'm going to run into issues
To answer your question... if you're worried about that, make adjustments to piston until it runs as desired . If you mess up just replace the piston.
How much do you charge to reed port a 460?
How does porting the intake lower acceleration speed?
Nitrow Boxhead bounty it changes timing, the more fuel you allow in per stroke lengthens the time it take to process. . that in combination with a 100+ lb. load creates a low end lag.. I usually try to find a healthy medium with gopeds and mostly just widen the intake with a minor timing change.

Nitrow Boxhead bounty my pleasure
Your the man
Thanks, Hopefully I can make an updated video soon.
Want to see a g320 done
caged lion it's not a whole hell of a lot different.. follow same rules and your good.
I just bout a g2d 40$ off offer up bout to rebuild and do a lil port see how it turns out
I know the top and bottom fucks with timing and is best left alone
caged lion timing needs to be adjusted
Thanks
What do you charge to do this
$100

Yes
@@Perkins.porting OK cool just was checking I have you on Facebook as a friend an was making sure video was from you lol
