2Stroke Stuffing sent me here!

Its nice to see someone who really knows how to do this the correct way.. I do it very similar just manual wich is little less accurate but works good.. With two stroke cylinders its hard to get them honed perfectly near the ports

I learned a lot from you. I have successfully rebuilt 2 stroke outboards with my Kwikway boring bar and sunnen an112. Information on honing cylinders isn’t easy to come by but you set me up for success and I thank you for that. Wish I could meet you in person and see your setup

Спасибо Марк за Ваше очень поучительное видео! ! ! Много раз пересматриваю и учусь как нужно делать. Это лучшее видео в интернете 👍👍👍

Currently rebuilding my Kdx220r and this video is more than welcome ! thank you very much ! If i wasn't this far, i would've sent you my cylinder, can't beat a pro ! And btw, 2strokestuffing sent me ;)

Man I came here to learn how to use a flex hone now I'm leaving feeling completely inadequate...you see the quality of that cylinder...holy hell!!

Love your videos, Mark! They have helped me tremendously. I am in the process of doing a full tear down of my '99 Sxi Pro. I have the motor out and ready to rebuild, but I am actually planning to send some work your way, if possible. I'll be in touch! Thanks again!

A lot to learn here, thank you for taking the time to share. I was surprised how quick each step of the process was if you know what your doing, I obviously don't. Can you tell us what kind of quick release nuts those are on your fixture?

Nice info on the 2-stroke stuff!

Great content Mark! Subscribed. Reminiscent of the OG articles from Klemm and Grabowski in the early Pwc mags. Good stuff! Gotta keep the 2 stroke alive!

What a pro! Very impressive skills

Ive been veey inspired by your videos and am doing a cast liner in a summit 800. The issue I am having is getting proper hone depth at the bottom of the cylinder. Because the hone is just shorter than the cylinder its doing the middle more than the edges as well. How do you counteract this?

Great videos! This channel has helped me out a lot. Thank you

Great Video, You use grint 70, 150, and the fine 280?

Sunnen make two stroke hone stone/guide sets. I used to teach it at MMI (2000-2011.6) It's relatively easy to get 0.0001" tolerance round and parallel even with the drill motor version of Sunnen (in fact, I find it easier as you can feel the slightest torque variation if there is a 'tight' spot) You do need a good low speed drill though , I think 450 rpm is max on a 2.5"~55mm bore IIRC?

Also would of been nice to see how you fit the rings into the cylinder 🙏

Very good video. Lots of good pointers.... I personally like to use a low speed drill motor (using one of those Goodson honing tanks) and do it by hand so I can FEEL the torque and cutting action in my hands. I find that this gives great tactile feedback. You can literally feel when a bore is barreled or bell-mouthed in your grip. But I mainly work on much smaller bored (46-52mm kart racing motors). I have always been personally able to get better results by hand than on a horizontal rigid mandrel machine like an MBB...where you lose that hand feel. Have you compared the profile results from brushes vs using a really fine stone, like 500-600 grit? Also, how often do you use truing sleeves to maintain the stones? Nice work....

Hello, can you tell me if the brush has grooves to hold oil and reduce friction on the engine? Thank you.

I was about to use the first honing tool to hone my jetski engine

What surface roughness is the best for 2 stroke single ring piston geometries? What do you use to measure the surface roughness? Have you ever honed smaller RC engines like say an OS MAX .60 or 10 cc engine? The cylinder liners are apparently tapered toward the top for better sealing. Does this work on 250 cc sized engines? It looks like you spin a wheel on the hone shaft to vary the size of the hone diameter. When it squeaked, you tweaked it a bit. If you tighten this too much, will it cut/grind/hone faster? If so, how tight to set it?

yeeah 2 stroke powa!

Hi Mark , thanks for die video, best one i have seen jet. IS this proses the same for nikasil 2 stroke cylinders?

I seen you checking the cylinder to make sure it wasn't egg shaping. I have experienced this before when honing. What do you do to correct this if it does start to egg shape? Alao, what's your most common grit finishing stone, 220 or 280?

2 stroke stuffing send me here👌👌

Have you ever used torque plates and see if there is any difference in cylinder taper and out of round ?

Still i like ur videos

Will a ball hone work on a two stroke? I heard it rounds the port edges..

Hello, What grit flex hone would you suggest for chainsaw cylinders with cast iron liners. I will be rebuilding several saw engines soon and not sure what grit to use to freshen up the cylinders. Thank you-just subscribed!

With the trickling sound of the oil, I've already made three trips to the john

Приветствую, подписан на Вас. Очень хорошая работа. Подскажите пожалуйста, где можно купить такие камни sunnen?

Man this is so cool. Does it cost a customer a fortune to have it honed this proper way?

Do you recommend putting case sealant around the lips on the outside crank seals? I just spent a lot of time rebuilding a 1999 Yamaha GP1200 Waverunner only for the PTO side crank seals to blow out within a day. Frustrating!

Good video! What roundness and straightness can you hold?

This sleeve are Chrome plated or Nikasil?

Im here from 2strokestuffing 💓

what about diamond honing stones?

how would you deglaze a 48.2mm 100cc cylinder in which the port edges cannot be altered from spec? basically the edges must stay sharp as from the factory as this is an engine for a spec racing category. iame italian engine 16000 rpm with a chrome ring

How much do you charge for boring cylinders?

Good 💯❤❤❤❤❤❤❤❤

See people on KZfaq with carbine bit on a 2-stroke cylinder and you don't want to use a carbine Bit right?

Bump

Where im from 40 bucks s a lot of money

What happens if your bit runs when porting? Is it OK as long as it's not above the exhaust where it builds compression? I've been told it's no diffrent than a scratch that's been in there years, as long as the ring does not catch it and it's below where it builds compression

Those balls slamming into the port edges sounds like a properly shhit idea.
