How long from you receiving and sending it back is the turnaround?

Can you please make a vid on how to use these and how to get the proper feel. Seems like my feel is always tight. Especially qhen using a micrometer. Any tips, or visual tricks would be an appropriated gem for me!

The jet ski community is blessed to have guys like you I enjoyed listening do your explanations even though most of it it's way over my head LOL

Great tech tips . Thanks

filled with oil i hate that im doing mine now.

If lifter is primed it will not compress. Can be 100% clean but oil will “hydro” lock it. I crank motor with no fuel pressure and they will all prime during cranking. So, assembly them dry or primed.

Do you know anything about simplicity boring bars? I have one of those and would like to learn more about it and maybe see if I can use it.

Hi great for your very interesting video little question can we reprogram a battery on BMW Style 520D F10 from 2011 thank you

In your experience. Do durability kits really help these 800 Motors. Or is it that two strokes can't have the same longevity as a 4-stroke engine. If the difference is minor, I would rather not even deal with it.

Do impellers work better fully polished or like a matte finish

Nice video,I have z Fowler that reads .0005 increments, can i just switch out the dial indicator for one that reads .00001 increments?

They do not perform better, all the ports now have a transition to the sleeve and that is never perfect on all the ports all the way around. Also, the heat transfer is much better with the plating to aluminum than the thick iron sleeve.

I watch thid video 4 years after you made it but it help me on my Sidewinder x2 thank you

Man I’ve been using an air powered dentist drill and a 2mm carbide end mill. It’s just like a drill but it actually works and it’s kinda fast, you can just plunge straight in and then wallow it out until it’s thin enough for you to chisel it out or stick an extractor in there. I’ve seen you do a lot of porting so I’m sure you’ve probably tried small endmills before but the dentist drill spin at like 30k rpm it really is a big difference. I also could never find a small carbide endmill that would go in an air dremel until I found the dentist drill

Paying the rent good job though. I wish I had access

Looks awesome!

I have a 550 over bored 1 size and a marineer head about 170 compression on both cylinders. Would I have to change the jeting from the jeting you listed

The Snap On TECH2FR100 (3/8 digital torque wrench) is garbage. Do a quick search they have issues with the battery connections and shut off. The warrant is only a year so you'll use it 2-3 times and when its up have to spend $150 to have it repaired.

Can a 2012 rzr xp 900 be resleeved ? Nice video

Do you have a part number for those. I have the same problem. Do you know if the 777 and the 944 paw (tooth part) interchange

how do you remove the coupler? im trying to taske mine off now

Does not cover how to file for 2 stroke ring end location pin

Hi. Have I got this wrong! But you had 50cc and you was left with 29cc doesn’t that mean you have 21 cc head or, am I doing something wrong. Tony.

Anyone know what snap on would charge to rebuild that exact red 3/8 torque today in 2024 ? I have exact one.

The modern YZ250 2-stroke (I have the 2019) has a problem that I am sure causes a lot of damaged pistons, ans is related to a cold seizure. The jetting is so darn rich stock, the water takes forever to warm up. I am not sure mine even got to a good operating temp. I bought my bike with just 3-4 hours on it, and i am sure the previous owner was just impatient and took off before the water was warm enough. I bet many kids do that with the YZ. I rebuilt the top end, (and modified the engine for more low rpm power), to find the stock piston had a slight 4-corner scuff, but the major damage was at the exhaust port. The hot piston expanded before the cold cylinder could, and forced the piston into the exhaust port. The top ring groove was wide with a budge on the crown edge (and looks ready to come apart, but it still ran good), and the lower ring groove was squeezed shut against the ring. I will bet that up to 80% of those bikes, (because i now how impatient kids are), with stock jetting, has a damaged piston in the jug. I have changed every jet in that carb (after raising compression which did lean it out a bit), and it is still running rich in the middle (have to change the entire needle---again.) It was amazing I was not fouling plugs with the stock jetting,--but it was close. I know 2-strokes with a carb are jetting a bit rich from the factory (because of different air quality around the world), but that thing would ruin the backs of my jerseys,---it was spitting so much oil out of the stinger.

If the lower rod bearing is sloppy enough to change the squish clearance, you are probably going to put the rod through the cases real quick. That one is a bit out there man. But I will keep watching.

I just feed the wife beans for the braps

Brapping 😂😂😂😂 brap brap brap flies 😂

Most critical measurements and tolerances! Precision instruction!! Thank you*****

I thank you so much, for spending your time for making this video! I went with the Mitutoyo based on your opinion, because I'm in Europe... Best comparison of bore gages on the whole internet! Thx, Marlon

How much are your templates? And how much do you charge if I sent you a case and cylinder??

Amigo ayudame con lo sigueinte. Puedo poner un estator de una 800 en una 787 ?

I was hoping you would mention pre-ignition as well for detonation but all around great video

So the tech series dnt have the degree factor in them as well?

I bought a blown up 2015 YZ. Massive detonation damage. The timing (aligned marks) was WAY off. Set it with a dial indicator to factory specs and have been all set since. Its easy to jump to the carburetor or the seals. But rod bearings, crank bearings, timing, and the head (did someone cut yours along the way?) all need to be checked.

I have a 1992 Yamaha Waverunner VXR (WRB650) with a short shaft. How can I find out what bearings, housing and oil seals my jetski has?

Good video, thanks for sharing.

My request to you is, please upload one full vdo on feed mechanism of 777. Thanks

Make vdo for feed mechanism ,how it works and what problem arises when not repaired in time . Thanks

Where is the choke???????

Please let me know the DRO you put on 777, how much it cost and from where you purchased this . Have you ever opened the feed mechanism of this machine. Thanks.

Great video. For youngins who are new to the trade I would highly suggest adding your clearance to the piston measurement and zero the gauge with the 0 on the 12:00 position. Seems easier mentally to hit a dead zero than to his say 2.5 over. Visually you can more easially identify how close or far you are from your final dimension.

Tira uma dúvida o motor 62t com 2 carburador, é melhor que o 61x uma carburador

any reason you didn't put a X2 mainboard in, as it looks the same with a bit more speed ?

This the scumbag that mocks children? Poor excuse of a man. Behaves like that to a little girl, imagine what he does to his wife and kid behind closed doors.

Do you have a base for idle screw when tunning the LS ?

Do you trust the 5-125 snap on down to 5lbs? Or do you use a 1/4 on the small stuff like cam caps?

Qual é a diferença para o 61 x e qual a diferença entre o 62 t

Hey Mark, I'm missing your videos. I hope all is well with you and your family. I'm looking forward to seeing your video on piston wash.

I have two 1997 Kawasaki ZXI 750 they both have the stock Keihin carbs. I recently rebuilt the carbs on both due to fuel pump issues. I noticed that the Keihin carbs I have, have 3 jets but I have another set of carbs I purchased used, for parts that have only two jets. Can you tell me how or if the 3 jet is better or worse than the 2 jet carbs? I assume the 3 jet will have more of a midrange performance over the two jet? Thank you for your videos, I have learned so much from them.
