Taking This Cylinder to The Next Level... (Must See)

[@lil_wheelie6599]

I know that you mainly only do quads and bikes but have you ever thought about rebuilding a jet ski? I think that it would bring in a lot of new people to the Chanel. I’m just one of thos guys that likes quads, bikes, and jet skis, it would be so cool if you did.

[@hrodscith9168]

At our shop we work on all three and side x sides jets skis are the best would also love to see it also

[@jacksonrice2209]

It’s be cool to get an old standup

[@careysoutherland8291]

id love to see some two stroke built personal watercraft.

[@leon760]

agree

[@MichaelSabo]

I haven't really thought about a ski but I would certainly love to build one; it would be taking on an entire new skill set I am sure

[@IllestA4]

The crank being true is the least of your worries, ALWAYS check the side clearance, just had a new Hot rods crank that was .006 right out of the box which would’ve self destructed in a couple hours or less, had several that were .004 as well which is why so many people have problems with new wiseco and hot rods cranks a few hours after rebuilding, extremely wise to have someone pull and reset the rod if at all possible. Killer build though! Can’t wait to see it finished

[@MichaelSabo]

Interesting; thank you for the feedback on that; I haven't heard that but I definitely will be checking mine 👊

[@IllestA4]

@@MichaelSabo well worth going the extra mile for longevity, some run fine right out of the box but it’s definitely been a problem with them being too far out of tolerance, machinist I use gets them within .001. If a crank locks up and it’s blue on one side the side clearance was 100% the problem, good luck!

[@paulmryglod4802]

I just had my 97 cr250 built. Stock crank was true and in good shape. The builder mentioned that he's had brand new cranks come out of true. Excess runout he called it.

[@nathansumerlin8391]

On the case step, most small bore/ big bores that are bolt on’s don’t need blended, as a builder you should rotate the motor through full travel and check for interface. Blending areas that are “dead” areas can hurt power, change crank case volume, in some rare cases it can help

[@eschrader]

13:48 thank you for taking the time to talk about porting. Quick question tho, isn't a sharp angle where the two transfers meet the case bad for performance? When reading into all the porting stuff that's what the general consensus is, not to sharpen that piece.

That clear plastic piece is a template in case you need to cut another gasket to the same spec.

[@kaidenseaman7177]

I like the fact he doesn’t do a lazy job all of that cleaning just makes it better when it’s all together and u can say u built it

[@jamesrickwood6333]

With matching the transfer ports if the gasket is too big I cut a biro pen and dab the ink on the cylinder then put it on the case.. Then clean the ink off when done.. Your way is better

[@kurtsteele5587]

What kinda bit you using and at what rpm for it not to be filling the bit with aluminum?

[@sersge]

you need a dentist tool, or a homemade 90degree angle tool for your dremel to get into the ports ! greetings from germany

[@THEDUKELOVER]

deff interested in seeing this thing in the bike and kicking roost

[@F5Tornado44]

Hey Mike, 1 thing I learned from some master engine porters is the air flowing through a 2 stroke motor is subsonic, and subsonic air flows easier over rounded edges. Try rounding off the center transfer port separator bridge a little, instead of knife edging it. If you like doing porting, you gotta invest in a right angle dentist drill/grinder. Then you can get into those transfers, where the real power is made. Nice job on the port matching, even the skirt trim.

[@MichaelSabo]

Thank you for the feedback man! You know what's crazy? Dave Moore told me that exact thing about sharp edges. The reason I brought it to a point is because I've observed that in many ported cylinders. I have a feeling for this platform you're right though, especially because of how high revving 125's are. Maybe I will try both ways and see if its noticeable.

[@patp2462]

If you round the edges it will make a turbulence and slow the flow if you knife cut the edges it will just split the air here is example if you look down at the pillars on the bridge in a river they are around it to slow the flow and you can see the turbulence If they knife cut the pillars water would flow too fast just my two cents

[@MichaelSabo]

@@patp2462 I think youre both correct depending on the format. I think the rounding of the edges only applies at very high velocity; all theory; I don't actually know.

[@F5Tornado44]

@@patp2462 So why didn't they knife edge the leading edge of prop driven planes? I understand that the shape of a wing creates lift, and the leading edge has been changed to more of a knife edge for modern supersonic aircraft. All subsonic aircraft still use a well rounded leading edge. Like the modern day airliners.

[@F5Tornado44]

@@MichaelSabo It may be something that you can't feel by the seat of your pants, but in a flow meter, it will show better flow. At least that's what I've heard from the experts.

[@backyardprojects8153]

[@manaaalsuwaidi3643]

Awesome work man 👍 I like it 💪

[@420banshee7]

I know you did a good job cleaning up all the seams and rough edges and opened it up a bit and whatnot but man it still looks pretty rough on camera you need to get you a good kit of Dremel bits that are different shape and different grits in stone and really be able to work through the different grits and really polish them all up a lot better and it will drastically help everything flow a lot better over the smoother surface and in turn end up with a lot better performing machine or even finish up with some different grit and different shapes of fiber bits as well to really be able to polish and smooth everything baby butt smooth and it really does help everything flow so much better to the point where I'd say you will feel the difference in performance that rough stuff really hurts the flow and overall performance.

[@dennisbrooks186]

So far nobody caught it? I deff did, cut the sleeve higher to match that up to the alum. And actually a nice job too bro, what u did here is actually like as beneficial if not more then just hogging out the ports. Nice job! Bet she'll keep up with the 250s now!!!

Im interested in what type of tumbler and medium does he use to make those cylinder jugs look polished out like that. If anyone knows, I'd appreciate the help.

[@gavinbarham542]

Vapor blasting

[@gavinbarham542]

Sorry I commented before watching the video. He has had parts vapor blasted in the past that made the stained aluminum look brand new clean again, but not polished

[@coloradodirtbike5930]

@@gavinbarham542 yeah I know all about vapor blasting and media (soda) blastings, as well as cerakote, powdercoat. Just was curious what kind of tumbler and media he was using. To get a cylinder jug and head polished to a mirror looking finish without scratches, takes a lot of labor (I've done it to a full 2003 honda cr250r - polished most of every part on the bike to a chrome mirror finish, engine cases, carb, brake reservoir master cylinders, and so on. It wasn't fun to say the least, not to mention the countless hours it took).

[@MichaelSabo]

Jared is a friend of mine who has the tumbler/vibrator. I don't know what media he uses, but it took 90 hours to get it to the shine it has in the picture I posted.

[@coloradodirtbike5930]

@@MichaelSabo much appreciated for the info.

[@adammoore5686]

Get tootsie rolls for your die grinder. It will smooth everything thing out. When it tears and starts flapping, that's when it does its best polishing.

[@MichaelSabo]

They are the best! I do have some of those and forgot to use them!

[@thetwostrokerebuilder]

Nice job 👍 you can easily match ports with case split. Put cylinder on each half and can see what needs to come out.

Keep doing you Your results speak for themselves

[@Ryanharrper]

Do you have to change power valves when you get a big bore cylinder?

[@MichaelSabo]

I don't know for sure yet because I haven't compared them side by side, but the Athena kit comes with a new power valve, so I'm going to guess yes; probably matched to the size of the bore.

[@motoblast3574]

Vapor blasting would have made that cylinder look and match the cases perfectly!

[@just_in_time5518]

Why do they ship the new head out all rough like that!? I would be pissed! Even more so where the power valves go! Like you said that should be more smooth. I don't blame you for trying to fix it and make it better! Good content brother!

[@MeachPango]

Is a 250r a good starter 2 stroke quad to start with? I have over 10 years of experience with riding in general. Just not with a 2 stroke.

[@MichaelSabo]

Riding wise, yes; great well mannered quad. Work wise, I would say no; depending how modified they are, they can be more on the finicky side when it comes to getting them right. Just my .02 and from personal experience.

People that make fun of homemade tools obviously have not been in the mechanical field very long. There's alot of times where a homemade tool is the only way to go. As far as your crank stand as long as it was cut and built the same height a parallel to each other I see no issue using it. I've been a machinist for 12 years now and I don't see any issue with how you are using the dial indicator.
