- Ideal for Zenoah RC boat & car engines.
Mount an old piston to the table of a drill-press and using a carbide cutting bit, you can shave off some of the bridge-port....Just be sure to knife the now flattened edge. - แนวปฏิบัติและการใช้ชีวิต
Great idea
Awesome video bud great job some nice information keep up the great work bud braaap 4life 🤘
ได้ความรู้มากเลยครับ
Porting and polishing is for making the engine create more power!
Cool story lol
Hi! I've got a TL52 (TL43) engine.
I haven't ported a piston ported engine before so I don't know what duration works best.
Do you have any advice?
Or where I can read about it?
I haven't checked the stock durations yet but will do that.
Thanks.

Are this realy work?? I think its maybe work but not good in low rpm cos the gass will flow to exzos port before piston make compression..large comsumtion fuel use n waste..sory if i wrong..

Haii buddy what's the use
What bit did you use?
It's a 1/2"x1" cylindrical carbide bit. You can find them ebay/Amizon for under $10
What does that do?
Increases port time area. Which gives the cylinder a little more room to pull in more fuel and air. A little more fuel to combust = a little more performance gain.

Ok but you did not explain why this was done?
It's mainly to give 2-stroke porters the idea of what can be possible with the right tools. A lot of RC 1/5th scaler's like to trim down the transfer bridges quite a bit and often times I notice how horribly hacked up, uneven their ported cylinders are. So...To answer your question, raising the transfer bridge can give you a little more peak RPM. There's an RC engine called: Tiger King S27 which has their transfer bridges all the way up at the BDC line. Anyway hope this helpful.
@@TheNoisePolluter this can be done to none marine engines?
Yes, this type of mod is done a lot on RC marine engines.
@@fdrc8099 This cylinder has JB-Weld added to the intake port for a billet reed crankcase.
@@TheNoisePolluter i did this to my 400 dirt bike dont know if it helped. I did too many things to the motor at once
