My Porting Setup | Affordable And Functional | 2 Stroke Tuning

[@monkeyjuju7441]

Surprisingly my Dremel (395 type 5) has lasted me since sometime early 2000, so 12-18 years and in that time I used it daily for probably 6 years making guitar pedals, electronic cigarettes, custom computers, PCBs and other electronic devices, and surprisingly (I'm kind of ashamed to say it) I've not once cleaned nor lubed it, nor have I ever housed it in the fancy case it came with, and it still works like new. It's by far my most frequently used power tool(maybe tool in general) so I'm surprised yours broke so quickly. Granted I have my grandfather's circular and jig saws, cordless drill and sander, and all still work, so maybe the older stuff is just built much better

[@overr8ted2]

You may already know but if you spray the bits you are using with WD40 it will help stop the bits clogging with aluminium I use this a lot when porting heads you have to keep reapplying it but it works great

[@AuMechanic]

It works well, you can get a wax stick also that is for that purpose, you dip the burr tip in it now and then and it keep it clean.

[@2STROKESTUFFING]

+overr8ted2 Thanks for the tip!

[@robinrussell1232]

I’ve always used a chalk like, metal marking product called ‘soap stone’ or ‘ keel’. Not near as messy as a liquid. Works well with a file!

[@glennlurman3514]

Its funny ive been working on small engines for 25 years 90% of the time with no protection on (Cant tune a small 2 stroke if ya cant hear it) . The only time i had any eye problems was when a piece of grit got in the eye from on the inside of the glasses. Also Hearing is fine and Tinnitus is a good excuse to not listen too the missus (Sorry love ringing in the ears ya know).

[@topepmc]

Good to see you wearing eye protection! Last summer I got 2 steel shavings and a bit of welding slag in my eyes in 3 different situations. And I've learnd! Not a good experience!

[@bmjca123]

Hard to get out of your eye when the metal cools into it

[@pascalrieder9216]

4:54 a headlamp is also nice to have

[@CannondaleF700]

*Do a video of you getting wasted with friends and blowing engines up that are not 2stroke, to show your love for 2 stroke*

[@2STROKESTUFFING]

+fishsticks Haha, great idea!

[@fgtldyjxgzyjxriceicr9880]

2STROKE STUFFING ja, gjør da!!!

[@stretchedbmx]

A lot of times if you put some wd40 on bits they won’t load up with aluminum. Not sure if that works with stones though

[@TheForcedinductn]

Good stuff, need to build out my collection of porting tools :D

[@2STROKESTUFFING]

+FORCED-INDUCTN Thanks!

[@late9462]

i heard somewhere that if u use wd40 with those stone bits, it wont collect aluminium to itself. dont know if it works but i guess its worth trying

[@mcgregor711]

For the stones. Dip the stones in wax then you can grind a little. Then dip them again. They won't clog up as much. Also try to make the ports look like a golf ball. I've had good luck with this on port velocity.

[@2STROKESTUFFING]

+Jason Schneeweiss I've seen this golf ball thing done. Any data on gains?

[@johnvanberrgem286]

Jason Schneeweiss golf?

[@billshiff2060]

@@2STROKESTUFFING Dimples only work on golf balls at a CERTAIN velocity and only because it keeps flow attached that might break away from the surface. If they have any benifit in a port it will be just ahead of where you might think the flow will separate. EX: in the short side of the transfer walls just before the turn. Even then it only works between ~180-200 Feet per second. Above and below that the smooth shape is better. Golf balls are driven in that range of speeds. Port velocity?? not so much. Add to the complications that all those speeds change a lot with temperature and also with fuel vapor and droplets. Just randomly dimpling the whole thing will likely do nothing if not hurt flow.

[@aaaabababa]

That Flexshaft is a good tip, i had problems with my Dremels going bad until i started using better Airdremels.

[@122martin122]

Do a video specialy for chamfering ports after a porting, what is not enough and what is too much, nice videos keep up!!

[@2STROKESTUFFING]

+lenny exe Thanks! Could do that!

[@Sketch1994]

Before you do make sure to check out a TZ250 service manual...it has a lot of details on the subject and I was surprised after seeing what they meant in person (I have a TZ250 cylinder for a cylinder swap right next to me and the roundness of the port lips is insane)

[@2STROKESTUFFING]

+Sketch1994 My philosophy in short: No chamfer whatsoever on transfers - reduce tendency to backflow. Huge chamfer on exhaust top edges - enhance flow.

[@Patricks_Projects]

Use 'bivax' or atf oil. Dip 'stones' into,, port away!!! Works a charm ;)

[@boharris8179]

Try using wd40 or marvel mystery oil or the equivalent of them that's available to you and dip your burrs and stones in the oil b4 grinding on Aluminum. It really helps keep em from loading up

[@chrisstone8189]

I know this is old, but I was wondering if you still use the Marathon dental tool. Also I see they offer different angle contras (latch, push and FX style) wondering which type is best ? Thanks

[@rollintwincam]

You should also wear a respirator! Breathing aluminium dust is not a cool thing :D

[@coltonward3609]

Yea but you ever see a millwright throwing on mask to grind some shit?

[@k-techcowboy4260]

Who was the company whos tools you mentioned first? I do alot of porting on small 2 strokes. Primarily chainsaws and other power equipment and plan on getting a job at local shop that carries Billy Goat, Briggs & Stratton®, ECHO, Honda Power Equipment, Hustler Turf, Kawasaki Engines & Power Products, Kohler Engine®, Mantis, Scag, Shindaiwa, STIHL®, and Toro® and I plan to introduce them to the benefit of offering cylinder modifications for guys who want either a basic woods ported work saw all the way to a turbo ported hotsaw that runs on methanol.

[@Ketis1985]

CC specialty

[@Pereke69]

i was hoping you gonna talk numbers, but okay, keep that two stroke stuff up!

[@2STROKESTUFFING]

+Pereke69 I'll do that another time!

[@davespooney8472]

Hey, are you predominantly a moped guy or do you also do off-road/bigger engined road stuff?

[@2STROKESTUFFING]

+Dave Spooney Mostly mopeds but nothing against bigger stuff, might come in the future.

[@kelco2246]

well done your getting better every time you post a video

[@2STROKESTUFFING]

+kelco2246 Thanks! I try my best!

[@andreasjohansson1964]

yay long vid's :) love meaty vid's.

[@2STROKESTUFFING]

+Andreas Johansson 👍

[@meisterzyleta5240]

Thanks bro for all, lets porting ;D

[@Maltsun-Henkka]

What is the red tool called?

[@muhammadsyafiq7760]

Nice setup mate. Currently building my own portibg setup too. Want to custom port my cylinder, YAMAHA TZM 150 with power valve. Can you suggest what angle for all porting that suitable for me. Looking to increase my power.

[@kd9432]

That's funny I repair all those medical tools for a living

[@marioraja4229]

where should i stop with the exhaust and intake timing?

[@2STROKESTUFFING]

Much past 200° on the exhaust is not advisable, max for intake depends on what type.

[@fergusonhr]

Love your vids bro...

[@2STROKESTUFFING]

+Gary Ferguson Jr Thanks!

[@tomminaukkarinen9465]

can you but link from that right angle tool

[@2STROKESTUFFING]

Search right angle dental tool on ebay.

[@nightmareinaction629]

What is that thibg you turn on in your intro the one the shoots some hot sparks

[@Gazgit555]

A industrial heater. Runs on parafin or gas

[@2STROKESTUFFING]

+nightmare in action nighmare in action It's a heater. Cold here in the north...

[@elmerfredeluces8896]

Can you do porting on a vortex mini rok 2 stroke engine?

[@Ro-Bucks]

Are the spx cylinders the same size as the 80cc pocket bikes? its looks near the same size.

[@2STROKESTUFFING]

Probably, it's from a 50cc pocket bike.

[@Ro-Bucks]

Love your channel by the way, It helped me a lot. I'm outside porting the crap out of a motor that was blown last week, fixing and modding today.

[@2STROKESTUFFING]

Thanks man! Good luck with the port job!

[@grantmara769]

What do u think about the dimple effect ?

[@danielwest5729]

How big chud the ports be on my 2 stroke cylinder? (Sorry for bad spelling)

[@2STROKESTUFFING]

That's a difficult question... Depends on ALOT of things.

[@danielwest5729]

2STROKE STUFFING do you know were I can find the math for it

[@2STROKESTUFFING]

Gordon Blairs "Design and simulation of two stroke engines" for the math. In short you want the ports as large as possible while retaining the "right" angles, enough blowdown, and sensible durations.

[@vladimirstraciak6705]

You just need to soak the stones in diesel or some kind of oil and it wont get filled with aluminum.

Use some gasoline on the carbites It won't cool weld so much on carbite dip it in gasoline 😎😎😎😎yes man safety gr marvin

[@2STROKESTUFFING]

+Marvin Lokers Thanks for the tip!

[@tielemobiel]

I use chalk on my carbite burrs when cutting aluminium; the aluminium won't stick to the burrs
