- In this video I ported the cylinders. This is my first time doing any port work. I think it went well.

Thanks for watching! - Авто/Мото
Kens Garage is such an underrated Channel!
My NS400R is Finished now and my RD750 TZ Replica Build is under construction :)
Thanks Fin's for the nice complement. Is there a place where those of us interested can look at your motorcycle builds or just get more information on them? RD750 TZ Replica? That sounds extremely interesting.
it will be nice to see the dyno test before and after the elaboration
Anyway, good job
Unfortunately I have no access to a dyno. Butt dyno says it runs remarkably good. I'm very happy with the results in performance.
Hats off to you for having a go yourself at porting. It must have been very nerve-racking.
From the tuning job I had done on my old YPVS, the exhaust port was quite a bit bigger than standard. But it was best part of 40 years ago so I couldn't tell you more than that.
I suppose a bit nerve racking Ian. But after a while I got comfortable with it. I got a real good "report card" from Brian when I dropped off the cylinders and head. Never at a loss for words he gave me lots of great porting tips. I listened as a good student and may do a little more work on the ports post boring.
Very good Ken...!!
Thanks Ricardo.
Hi Ken some advice from a porter, buy long burs and the rounded tip is best as it doesn't dig In, also don't cut dry as it will clog the cutter, best cutting fluid is wd40 with 10% 2 stroke oil, I mix in a spray bottle and have it hanging on my porting bench, I have the airline next to me so I can blow all the swarf out, also it washes texta off so I scribe all my lines with a sharp scriber, if you don't want to scribe then you can dip your carbide into the wd40 mix and it will keep the carbide clean and cutting
Danno, thanks a bunch for checking in here and leaving these comments. This was my first attempt. There are more in the pipeline. Next time I may try your "premix" solution. Is there any chance you can leave a link to the cutting tools you are suggesting?
Ken Jeggs has a 3 pack of long shank burs for porting, I use a few different ones but the oval head and the round head cutters work well, there's some thin round head cutters the width of the 6mm shaft and there quite handy too, as for the knife edging it's supposed to hinder flow but all I do is cut the transfers right down and they end up knife edged or very close too and then I take a bur and round them over a tad to aid the smooth flow over the peak, keep playing 😊 I enjoy watching your vids, also look into degreeing your engines and then you can work out what port degrees work for your desired outcome,
@@Grooty79 Danno, I'm not finding long shank burrs for porting when searching Jeggs. Is there a little more to that name? Thanks for the compliment and now you've given me something else to think about, i.e., degreeing your engine...
The rz s a cool bike in stock form,you can allways do banshee 420 kit with pipes if you like a good powerband.
Cool with this Tools 😅
Thanks for the comment!
Also ide like to add every bit you remove off the transfers relates to a change of degrees in port timing, other thing is raising the exhaust port 0.5-1mm and port matching case to barrels plus a little intake window is all most people need just to wake them up
Thanks again Danno!
One other thing go surf all the Yamaha banshee sites you can find for info on porting degrees it will give you lots more ideas to try 😊
@@Grooty79 Yes, endless surfing has got me to where I am. Herr Jugs Racing RUclips channel was helpful.
Jim at passion racing did our banshee years ago added intake port directly to transfers
Great stuff.
Do you happen to know the exhaust port open duration of the rz350 or rd350 ypvs in my country?
I can't find this information anywhere.
. thanks
Kenoconnorracing have some good videos !
Thanks. I have watched those videos. Very informative.
Qual Manual e este ?
Big holes is not necessary for a good and high Power. I get over 80 PS without big holes.
What have you done to get 80 PS on your engine? Thanks.
@@KensGarage1 You can read it in the top of my Videos. There are the main parts of my tuning .
Usted no tiene ni idea de lo que está haciendo.
I put your comment into Google to translate and it came back with "you have no idea what you are doing". If that translation is correct, will you please offer some advice for proper porting? Much appreciated!
@@KensGarage1 It is very easy to get more HP on the RZ 350, but it is even easier to damage it. If you raise the five transfers 1mm, you lose exhaust time, for example. You must KNOW what you are doing. I see in your video that your RZ 350, sounds, it works and runs very well. Do you want more? Two stroke tuning is a very contagious disease and there will come a time when you will always want more and more and more... I encourage you to get it. Greetings.
@@jejerele Thanks for coming back with that reply. This was my first time porting cylinders and I think I was more than safe with it. The porting is not nearly as aggressive as my Thrasher bike porting which runs very well. The port map I got from a friend of mine that has done several of these. I am always learning and experimenting on these motorcycles.
@@KensGarage1
Engmod 2T. Best money spent in my life. You won't regret it.Enjoy your RZ 350.Greetings.
you better leave them alone that's a science and your outside of that relm
Thanks for the comment. The port map was used by a friend with great results. This was my first attempt at performing porting. You got to start somewhere, don't you? My engine runs perfect.
