85cc ! Stihl 500i Fuel injected Big bore!!! 

Thank you.

i’d agree with this comment

@@dynojoemods2764 have you tried Millennium for plating? BTW nice build.

This one intimidated me a bit, less band cut than normal and a touch higher exhaust port. But dropping the cylinder a touch more may be in the future. Curious how the ring will seat in.

Thank you.

Glad to see the injection is keeping up. I like the additional tests you did with the different muffler covers on this build.

Thank you! I am very curious the longevity of this build. It is going to get ran hard. So hopefully something is left to come back once he is done.

Thank you

Thank you, that is what the owners cuts out in the Midwest. Lots of hard wood. He will be running the snot out of it for Sure

Keep us updated on the longevity part. What you are going is just fascinating.

Yeh, supposed to be one place tooling up to plate, but nothing yet

That works too. Can't wait to see your project finished up

Thank you! He sure is catching on fast.

@@dynojoemods2764 fa sho bro! 😉

Thank you! Yes, they take a bit to get put together.

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

Sometimes the extra volume before the valve throws the reading off

They stopped doing blinds

@@dynojoemods2764 well cast iron it is then ! I know I saw a video of a guy plating in his garage but it wasn’t a blind bore cylinder. Even if possible to do a blind bore idk if I’d want all those chemical baths laying around in the shop 😂

I have never had a 133 on the dyno

I am hoping to get this saw back soon to try and find some more

@@dynojoemods2764 I’m in bay city , I gota find the time to come down one day , I got a 345 husky n a 026 id like to have you look at , I got a 372 also but you said ya dont work on clones , didn’t know your were in MI till other day

Gasket delete and machine work

Lol thank you

Plated will last longer, and produce more power. How much? Not sure. Prolly 3-5% more power and 10-15% longer bore life.

@@dynojoemods2764 I did email you about upgrading my 500i last year and I will be in line for the plated sleeve option. Keep me posted and keep up the great, informative videos.

You couldn't get a chromed sleeve pressed into the cylinder without cracking the plating. Needs to be installed then plated

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

When they work, seems to be on par. But I bougt a pair. And one was junk in 3 weeks. Other is going fine.

Sweet build. What about plating the sleeve? Wouldn't that give you the best of both, not a blind bore to get plated, but you'd have the plated bore 😉. Same deal up here when I checked, hey don't do blind bores.

Thank you

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

@@dynojoemods2764 That would be interesting to see how it works out.

@@PurpleNovember I have just learned that. Working on getting the scan tool to be able to check and recalibrate these

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

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

@@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

@@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.

@@mattfleming86 It isn't a big deal to open them on the manual, but line up while dropping the sleeve in has to be that much better.

They are pretty neat. You should have checked it out when you stopped by.

Will have to look into them. Thank you!

@@dynojoemods2764 cheers. Hope you can find someone. Wood love to see this become a kit.

@@victoriousvictor7978 Looks like they stopped plating this summer as well...

@@dynojoemods2764 no way! That's nutty. Seems like everyone is pulling the pin on doing that eh. Over seas stuff I guess isn't making it viable to try and fix shit now adays or something?

@@victoriousvictor7978 Yeh, it is rather frusturating lol. I would guess blind cylinder to be a very very small percentage of the work. I just may have to learn how to do them myself.

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.

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

@@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.

@@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?

@@cyrillepinton3398 The shorten powerband on the graph is the 500i "tune" they go rich as soon as it sensed any load. 98% of the time the 500i will give me that dip.

It had running issues, believe it needs recalibration. It is supposed to be coming back sometime.

@Dyno Joe Mods cheers. Guessing after this cutting season 2 of mine will be pretty tired and need some new life put back into them. No luck finding someone to plate them yet?

Where are you based I should ask first?

I've built a few 660'S . don't go to crazy in the horse power numbers otherwise you will snap the crank. ( I've done this before ) . a 101 cc big bore putting out 10.7 horsepower runs sweet and you can still work it all day.

They said no more blind bores

@@dynojoemods2764 shitty that's who I always use

It is pretty snotty

@@dynojoemods2764 I picked up a 3120 k and have got new cases for it ide like to oversize that

Michigan

Thank you. I try and get it together lol

They stopped doing blind bores

Nothing wrong with the software, seems to run pretty good

@@dynojoemods2764 You need to do it!Evan if is installed new piston

@@dynojoemods2764 You dont lisent to me!You need to do it no matter if runs good

@@dujeamizic3588 I'll take this one to the dealer and see if they can do the update. See if it makes any change.
