How big can you big bore a Kawi?

Great video, thank you!!! I am new to jet skis and bought a pair of 2001 yamaha xl800 this summer. My nephew was riding one when an oil line came off so now I have to for sure rebuild the top end but I was really concerned about the crank. Now I know how to check it before I decide how to proceed. Thanks a million!!!

No matter how much people try to sell the idea that nikasil cylinders are better, I will always disagree, Get new piston rebore and you're ready to go, Plus its less expensive 🙏

Also I've seen a boring table called the cycle pro boremaster that is built for small engines, would one of these be a better choice for quick bore jobs ? Most of the Kwik ways I've seen don't have stands and they appear to be another couple grand to buy.

I plan on starting engine service at my shop and want a boring machine. What would you recommend for dirtbikes and other small engines? I want to include small engines such as 50 and 90cc, so I will need a machine capable of 30-40mm bores, and up to 4" for larger engines.

Trying to figure out what flex hone to get for Yamaha wave raider, size , material, grit? Just for deglazing and cross hatch

Can you do a video on kawi 750 epoxy fill

Hey man I love your work and also want to do this but I don’t have a boring machine. Is there any way I can send you a pair of cylinders so that you can do this?

Is this typically cheaper than just having the cylinders replated?

Thank you that was very informative. It confirms that my cylinders are in fact egg shaped.

Thats a wide squish band... im assuming you have hella compression with those heads.

Wouldn’t follow the advice of JB weld. If it comes of it will destroy your piston and then your cylinder.

What kind of mig wire are you using? Stainless? With a stainless nut? Just curious, i got a bolt to remove in a New Rxp 300-X

Hello sir, could you tell me something about fixed bearing position and free bearing positions? I work with big windturbines and in these gearboxes and generators, the bearings always have a free bearing position and a fixed bearing position to allow axial movement because of expansion due to heat. But on smaller engines like 50cc two strokes i can hardly find any information about this. Do you happen to know anything about this? Kind regards!

Do you do mail ins?

This was a great informative video. Where can I get some of the up/down stickers for my printers?

Hey how do you wire these batteries up togeather?

Unrelated but your the person to ask! 1996 seadoo 787 rebuilt engine has run great 2 seasons. Only issue is the starter often struggles to turn the motor over and the compression is high on this rebuild. Should be 155 but is actually 175. It always starts but it requires wiggling the the flywheel to get it to turn. Starter (OEM) and wiring/battery are all 100% could this be the compression being higher? Is it worth removing the jug in an attempt to hope I can find a THICKER gasket the raise the squish and lower compression? I carry a rope to wrap around the flywheel to help start it and its just plain annoying!

i have a ultra 250x Kawasaki what do you charge to do this

so for high elevation lakes like 6200 to 6300 ft above see level, what pitch degree do you angle the props to?

Made in america... and we can never get ahold of them. Wax may have them made in China but for one they're in Aus. Competing with China on your doorstep is gonna be next to impossible. And if FP won't keep up with the demand, then I can't see how we can criticise someone for coming up with a solution that nobody else has.

Great content!

You should do a 2 stroke re ring video. For when people get low compression but pistons and cylinders are still good. Show the process on how to hone the cylinder and etc . I really love your videos and you make me want to work on my zxi 900 and slt 750. I been working on 2 strokes for around 15 years as a hobby and im always willing to learn more cause ive only did a top end on a kx 80 and a rm 125 before

Say the bore gauge 7th from the left I think is either a Dorsey or a Standard if I'm correct what you think about them?

Great video . Have one to fit on my lathe. Thanks for your time and effort to make!

06 YZ250 lean I melted the top at the exhaust port same damage as presented in video

This is a piece of garbage Lower put on clearance for $10 piece of garbage

Hey man I have 750 big pin I’m rebuilding it has cdk2 twin carbs on when I do the carburetor rebuild as shown in video would I then have to adjust any mixture screws when I install it back on the engine?

If you fuel got water in it could you see the same water damage and speed

Still have anything like this available I picked up a 787 96 xp recently and whenever mine gets fucked up I’ll be needin one in Cali boss 😂

Ohmg that is so much work ….never again..looks good tho

Did I miss the part of which direction makes it richer or leaner? And is it just the low speed screw?

My FSWii Kwik way I have had new since 1976 , Has bore many , many 2 cycles and 4 stroke Cylinders , lately I have bought Beam Eguipment cutter , work great . , still use it every week .

Wow, I'm having the exact same issue on my Sidewinder X1. This video was super helpful. Thanks for putting this out for us!

So how well has it held up?

Can you a 99 polaris slth 700

That is a horrible demonstration. Why did you cut the harness so close to the box. If something goes wrong with that plug, you're SOL. Then why did you so much die Grease on one side of the pins. You smear a small amount on a clean surface Let's say a lid to something. Then you put the other rubber grummet over the connectors. And down a couple of inches nu dip the connectors Or one connector at a time on what you applied down on the clean surface. So just a tip of the metal Faster receives the die electric grease. And why did you smear Dialectric grease Over the entire rubber seal between where the 2 plugs connect. Why did you do this. You just created a short between all the of Metal male And female connectors. You can apply non contact dial. Ectric grease for waterproofing None dielectric grease. You also have to be careful on whatever grease or sealand It does not get hot and flow.

How is your machine doing one year in? I want to get one and add the HTMR blast gun right off the bat.

Are you selling the block off plates for the older Yamaha 1200cc NPV engines? Great video.

Yup

Another tip, if you need to remove that bearing race, and for what ever reason those holes are not there, you can lay a mig weld bead on the bearing race. Once cooled it will shrink and fall right out.

Thank you bud. Brilliant! Do you happen to know the bearing number for the VN 777s?

Been boring for decades. Kwik Way FN hands down better than Van Norman . Van Norman is less maintenance

4 stroke lol, highly doubt it.

Is that wae ring plastic??

I emailed you.

Great vid

Perfect! Looking for little increases to tie together for performance. Does this increase volume and velocity. Trying to piece the puzzle together. Building a Tohatsu M50D outboard.

I guess yo teat you would need same temp so probably just no heating because a similar heated setup seems complicated but same hardware in and out of the ultrasonic to see the difference i know ultrasonic works but so does heat and i kinda assume the plastic is kinda thick for the ultrasonic to make much of a difference but just a guess

pistons are warped.
