(Part: 3/3) Strengthening & Enhancing the appearance of a Zenoah G270RC Cylinder 

love the video but you can buy caliper paint by the qt at autozone then you can just dump it in the gun and even add a reducer if so desired.

Awesome

Me to good work maty

Me too!

Thanks! I just use the virtual voices because mine sounds terrible, I begin to stutter and fumble everything and speak in a heavy self-conscious. I've never been good doing anything narrative.

TheNoisePolluter well keep up the good work, love your videos. Check me out on instagram: 2_stroke_mafia

With that little ovan

The new intake is now located in the crankcase and the old intake port is converted to an extra air/fuel boosting port.

I have a couple of personal engines built for my upcoming projects, but you can already get a lot of fancy bolt-on engine parts or components (GZR billet cases, stroker crank, billet fan cover, ESP ported cylinder etc.) I'm not sure if I'd have the time to build something personal for anyone though.

TheNoisePolluter 😯😔😟😢😭 ok I understand and its not just the performance I'm looking for it's also the unique looks to your engines they look so nice I don't know it I will actually drive my KRAKEN truck again turn into a shelf queen

The squish clearance? .020"-.025" Mine is set around .024"

Heat would more refer to the skirt to bore clearance....?

These pistons have a slight taper towards the top, the lower part of the piston is usually fine. A very common piston mod on these is to reduce the diameter by .004"-.008" up near the ring. Also, the ring gaps on these are commonly set at .011"

Oh ok that makes sense I’m used to two stroke motorcycles so that might help explain my ignorance... cheers

*Intake port gets blocked off, Exhaust is fully opened up.

@@TheNoisePolluter where is you carb now/? in the base with read valve

@@lucgyre9268 Yes, the carburetor is now mounted to the reed valve, which feeds into the crankcase.

@@TheNoisePolluter any pictures ???

The paint comes out of the can far too heavy, all the main open areas of the cylinder will already be dripping, while other areas are barely coated. The spray gun allows more velocity with less paint and gets into the hard to get to places....giving you an evenly coated surface.

@@TheNoisePolluter Makes sense, I prefer the old style spray can nozzles over the new high output nozzles. I work on antique small engine also. I have some videos on my channel if you want to check it out.

These Zenoah cylinders are nikasil, and is not at all an issue with the plating chipping off. Also, stuffing the intake port for a crankcase reed is a widely common procedure on these and has been done quite a few thousand times.

Peeled chrome? Maybe on the Chinese knockoff engines.

It's polished pretty well...And the cylinder is not over ported, Instead it's just the standard porting everyone does to these crankcase reed valve conversions. If want to see what an over ported cylinder looks like just Google: Zenoah ported cylinder.

Comes out of the can way too heavy and then drips in one area while another area is barely covered. Spray gun allows more air flow velocity with less paint, allowing an even coat.

It's going to run, this is a standard modification for crankcase reeds. I'm waiting on a custom longrod crank.

The paint comes out way too heavy from the can, you end up with dripping paint in all the broad areas and the hard to get to spots are barely covered. Spray allows for more air velocity with less paint and gives you a consistent coat.

@@TheNoisePolluter ah ok! I get that! Awesome work non the less. Please make a video of a motor like this running. What kind of power do these put out?

They put out around 3hp stock, fully modified is around 6-7hp.

Yes true, but these small engine don't generate the heat and the intake port sits below the piston when at Bottom Dead Center and is not a problem. This whole process is the standard procedure when converting over to a crankcase intake reed valve. There some 5-6,000 billet reed crankcases and an estimated 15K-20K cylinders that have been JBWeld'd. I'm the first to make a video on how that process is done.

Runs through a reed valve in the crankcase. Search: Trevor Simpson reed case

No...

In the small engine hobby world, these billet reed conversion crankcases that require a DIY epoxy cylinders is a standard practice and is very reliable. The heat generated in these small engines have no affect on the Epoxy, mostly because the epoxy sits below the piston even at Bottom-Dead-Center. The reason I don't have the engine together & running is that I've been holding out on getting a special longrod crank built, I tend to get meticulous and stubborn about having to go with 2nd choices...and trust me, if this epoxy mod was faulty I wouldn't waste my time and money.

@@TheNoisePolluter honest buddy I know cause I done it , I experimented and it just fails . The piece you've got on the old exhaust port can't stand direct heat as it just disintegrates, these motors run just as hot as any 2 stroke .the only way is to get another cylinder and cut a piece out ,and put a chamfer on it so when cylinders hot and piece cold it will go in .when running being the materials the same so will expand the same .turn some billet to fill the hole upto your cap on the outside . being I don't know where your ring gap is cause you changed it about with mix of cylinder and crank case you goto get it flush so your not snagging the ring . Even the best of epoxy we used to quick fabrication inlet manifold to check other carbs out but run more than 2-3 mins and it just crumble . They a champ tuner by me and he's getting 12-15 bhp from 29cc and he doesn't use epoxy either ,but am sure out of curiosity he will of tried as if you see the tuning he does he tunes to the maximum it can be ,the same guy tunes race tiger kings motors for tigerking.hes a multiple world champ so he knows what's what . You wanna have a look at his tuning as it helps no end as he breaks it all down ,dave marl PWC, in Google and click PWC site it's under tuning guide ,believe me you'll thank me for that once you see his site

paul dean googled Dave Mark PWC scrolling for what seemed like forever.... I’m curious to see what it is your talking about could you post a link with specific website please?
