In the long run which will have a greater longevity, the steel insert or a plated bore assuming you can get it plated? Plated

I like the sleeve. I understand heating the cylinder, but why did you not freeze the sleeve?

[@dynojoemods2764]

Heating adds enough clearance. Also the frozen sleeve steams up and makes it difficult to see.

[@ecstans07]

Those adapters definitely report way low. I'd say 50psi or even more on that size cylinder. My 462 feels stiffer to pull over than my 461. I get 190 on my 461 without any adapter, and the 462 shows 130 with the adapter.

[@hordboy]

I agree, that small of a combustion chamber, the psi will be off significantly. Mod the adapter with a valve.

[@larrywarner9314]

Did you try melenium technology they plate cylinders

[@rc-daily]

Why would the adapter show lower compression? Isnt compressed air, compressed air?

Stock 500i has no revs, peak falling off at what 9250rpm? The way that stretches out once ported though is impressive

[@robertodebeers2551]

I bought mine new, sold it after four tanks of gas. Sawed great, but set it down then come back minutes later and the saw wouldn't start.

[@KPMACHINE1]

Why did it have plating issues in the first place?

[@dynojoemods2764]

The cylinder came from a damaged saw to begin with. Air leak/straight gas.

[@bodeine454]

I'm guessing I've missed some prior videos to this build, gonna go back and look them up. My question at the moment is how does the fuel injection compensate for the bigger bore? Did you have to tune it with an electronic tuner or ???

It fuels fine on the high side. Has some low end problems, but waiting to see if a dealer reset clears those up.

[@10homie]

Bro, which stroke 500i ?

[@cyrillepinton3398]

Exhaust ports behave like loudspeaker vents : smaller surface leads to higher air speed thus saturate at a moment. Could you give us the exhaust port surface ratio in respect to cylinder exhaust surface ?

[@dynojoemods2764]

This is a bit different than most. Area at the cylinder wall is a bit larger than area at the muffler flange. And muffler outlet area with the dual pipes is much larger than both.

[@cyrillepinton3398]

@@dynojoemods2764 Interesting, effectively much different. Was it designed so, or modified it during your work on the sleeve ?

[@dynojoemods2764]

@@cyrillepinton3398 Mostly because of the larger bore and piston skirt. They allowed me to go much wider than stock. And stock has a relatively small exhaust flange too. So this is wide, small, wide again.

[@cyrillepinton3398]

@@dynojoemods2764 interesting. I would have not gone so far for two reasons: it's against the theory of two strokes tuned exhaust (conservative argument), and it leads to higher exhaust acoustic impedance for the cylinder (mechanic would say it accelerate the exhaust gaz speed at the output: more resistance). Could it be the reason of shorten power band at high rpm in regards to standard ported 500i?

[@dynojoemods2764]

That's a fantastic build Joe.. Just a question from a dummy.. Is it possible to have a c&c machine cut out the ports for the sleeve? I'm not suggesting that it would make a difference or that you should go out and spend stupid money on one.. My question would be if it would make things easier or even work with the sleeve? Love all the builds brother and am a loyal subscriber who is just curious.. All the best to you

[@dynojoemods2764]

Thank you. Yes you could fully cut the ports. Most of these being 1st attempts, I wanted to leave the sleeve and be able to set the ports where ever. If I ever did multiples, I would make a map and open the holes in the sleeve to 80% or so. Doing that, you have to be very careful not to mess up during install

[@shaner67]

@@dynojoemods2764 hey man, I really appreciate the response. Just wanted to tell you that I'm so impressed with where you fit in this community. All of the builder's / porters watch how you push the envelop. We all admire the courage it takes to do shit that no one else does. I completely understand the theory of porting the sleeve with reference through the holes drilled. Absolutely no one that I have seen has ever sleeved cylinders because you can't find anyone to chrome them for you. Please have a look in Canada if you haven't already done so, we have some great shops especially in western Canada. Anyway, I'm really curious to see how this 500I does in the real world of logging. Keep putting up the great content Joe, we all appreciate the effort more than you know. Cheers brother

[@mattfleming86]

@@dynojoemods2764 If you had enough axis on a CNC machine, including one of those rotational mounts you could probably build mounting plates with tight studs for indexing the cylinder. Id say you could get the cnc to do MOST of the work, reducing the need to even pre drill. Maybe even for rough porting. Then you are just going in for cleanup. Problem would be machine cost and programming time.
