Awesome to see you finally working on the bike again!

Oh the excitement to see a CB750 video come up in my subscriptions. Hope the new work area layout makes the rest of the build enjoyable and hassle free for you.

Im loving this series, can't go to bed if I haven't watched a episode

Great to watch this as a rehearsal for putting my '79 GS850 back together! Thanks Hack!

I just fired my cb750 up fore the first time. The Best Feeling ever after working on it for a year. It was a wreack when i Got it. I enjoy your videos.

WooHoo! Welcome to Hackaweek! Glad to see you are feeling better and ready to go in 2015.

Thanks for making this video

Nice see you on the Cb750 again, I was waiting such a long time that I started and finish the Sabre transformation. That was a nice one. But I really like cb750. thank you from Spain!!! I will donate for sure

Thanks for showing off all the videos !

Hey, another great video! I really hope all of this series is going to keep on being this detailed. That is, to my mind, what makes these video's the best! Thanks for sharing.

The video is spot on all ive got to do is tidy up and start cleaning all the parts all the best Paul

Excellent video. Thank you very much for all the tips. And I noticed the PSB speakers. You have great taste in speakers.

For years I heard you have to hone the cylinders, I never knew till now why and what that does. Good video!

I found the easiest way to get old pistons super clean is to soak them overnight in a can of Berryman's Chem Dip carband parts cleaner. That carbon in the ring groves will wipe away with a shop rag. No harsh abrasives needed.

I have used a hose clamp and a soda can in a pinch in the past.

This videos is gonna make my day thank you very much.

Thank you for all videos, good job! best regards from germany

Great video Deno. Garage looks sweet. Received the 555 tee shirt the other day. Really nice. Thanks for making them available. Looking forward to the next video.

You have everything squared away, I have garage envy :) great video

You used rings compersor up side down. Used correctly works perfectly easy.

I know this is old, but thanks for the video! I needed this information.

yay yaya yay woooo glad its back

very informative,very interesting,thank you john

When I was in tech school we dunked the pistons in ATF before installing them into the cylinders, I imagine it's the same kind of thing - a lighter weight oil that aids with break-in.

Good video! Thanks for the info.

Necessity is the mother of invention.

cb750 rocks!!! nice works

I'm glad to see that you're back at CB750 ! Maybe in future you can cover some of the mercedes project at work in a similar way ? I am sure that many of the future owners of beautiful 190 will love such a way of representation of their new toy ?

2002! Awesome! Learned to drive with a '68, that little sucker could really go!

...For the ring compressor, if you turn it over, you will see 3 little outdents, Those are there so that the compressor sits flush on the piston deck. With your method of putting the pistons in from the bottom, it should work the same, and help with getting the piston in squarely.

I was watching the Honda Aasembly line for the CBR and they assemble the engine upside down as well.

Very nice man ! I'm waiting to buy a good Honda CB 750 K

I did a 250 Twin star Honda for my son , it was a 1981 for his graduation from high school the bike was the same year he was born , to go back and forth to college and work . took 3 tries to get the timing right the chain and dots line up , had to turn the chain and ride over the cam , little trick , not in the book 180 degree off and it will line up .

this is great!

This is an old video but I wanted to mention that solvents will not remove honing grit from cylinders. It really needs to be washed with soapy water to get it clean.

I like the new workbench a new order in garage

You could use the ridge reamer for that Ridge around the top if it's deep

Thanks for the video. What setting should I use on the honing tool it self for a cb750? Thanks

crosshatching is what your looking for when honing

really awesome video and i really needed this to work on my 83 DOHC cb750sc and i really needed a guide on how to do this. the only thing wrong with mine is that it needs new piston rings and this showed me for the most part how to do it. I was wondering is it absolutely nesscary to remove the connecting rods from the crankshaft to do this or can it be done by just removing the head, cylinders and pistons while leaving the connecting rods in place?

hoooraaaaay!!!!

The other alternative method is to go spend the $12 for a ring compressor

What grit stone did you use? I'm about do this to my CB700SC

finally!

Hi :) I have a question... Why you don't lube a cylinder surface before you will put a piston? I saw that you lube a piston rings but cylinder was dry... And second question.. Why most people use "assembly lube"? Is better than normal oil - for example 10W40?

I'm probably the only one who would notice this: where did you get a tube of "Xerox grease" from?! Did you work for them? I did, for 17 years.

I'm looking into buying a soldering station, I only have about $100 dollars to spend. But I'd love to get into small tech projects What would you recommend? Thanks!

I also have a BMW 2002 turbo! lol

this is probably a stupid question but how much material comes of the cylinder not alot im guessing HackaweekTV

Isn't it true that as the piston goes up and down the rings turn so the gaps may line up?

How many bikes have you done cuz you look like and sound like you really know what you're doing like you've done this before a couple of times

I've seen two cheap ring compressors, a hose clamp wrapping either the cut out sides of a beer can, or the sides of a plastic soda bottle. Those automotive ones don't work well with small pistons.

Sir, don't you have any liquid cleanser? I just am imagining that a good liquid cleansing element like the kerosene will do the job

excuse my ignorance but is it possible to overbore and use an oversize piston in one cylinder only?

Is there a front or back on the con rods? (180 degree orientation in the piston)

Are you absolutely sure, that those piston rings are not the other way round? I would say, that the darker ring looks like it could hold the heat and compression better.. Also, those two angled edges in a ring transit oil for coolant.

Those piston ring will eat the walls quite fast. He didn't even gauged the piston rings to match the cylinder walls. Never seen pistons being installed from the bottom of the cylinders either.

yes, good mechanical skills but why replace rods if bone stock

you didn't check piston ring end gap??

See thats why people put pistons from top cause the ring compressor tool does not get in the way with connecting rod, there is nothing wrong in your method just wanted to mention it. Every method has there pros and cons !!

Just wanted to say "Thanks!" I was doing an engine swap on my Magna (put a VFR motor on my 1995 Magna) and the Motor had a burnt piston. I replaced it and used this video as a guide when honing the cylinder. I gave you a shout out in post #124 of my thread. Thanks again for sharing your knowledge. I put some links below. Link to where I referenced you: v4musclebike.com/forums/showthread.php?p=365971#post365971 Link to the start of my engine swap thread (if your curious): v4musclebike.com/forums/showthread.php?p=359942#post359942

Dont u already have an episode 12...?

Hey Deano, absolutely love these videos! I am doing the same with an 81 CB 650. I bought the same piston ring compressor but will be installing the pistons the old fashioned way. Is it possible to use the tool since it does not come apart and it is already connected to the engine prior to fitting the piston into the cylinder? In other words, with the rings compressed and you get the cylinder down on the piston - how do you get the compressor off?

where is the magna?

making it look so hard to install pistons. the tappered bottom makes it easy to slide the piston in. no need for compression tool.

Honda cb65o

its been so long you forgot this should be episode13 I think?

Where is the Sabre?

He made a serious mistake at the 3-piece oil ring installation !! The correct installation should be as following: Install firstly the spacer ring on the piston and put its 2 edges at piston's pin side no matter L or R and the spacer edges should not jump each other !!. Then starting opposite of this "ring spacing", place one of the two (thin rings) by turning spirally until seated properly and 1cm offset of this virtual axe !! Now place again the one of the two (thin rings) by turning spirally until seated properly and 1cm offset of this virtual axe, but not at the same side as the previous ring. So finally the 2 thin rings should be at the 150 and 210 degrees (opposite of) the spacer ring's clearance. Now install (spirally) the 2nd from top compression-scraper (dark color) ring and finally install (spirally) the top compression (chrome edged) ring!! Lubricate with plenty engine oil and turn them around several times to insure lubrication goes into rails. Now turn them to their final positions before inserting piston into cylinder, ensure all ring edges should be at left or right of piston pin and not at the same side of piston pin !! by this way you can have the best compression sealing and oil scraping back to crankcase. Never put a ring clearance at 90 degrees of piston rod (because these sides have the most gasses pressure). I hope this will help a lot, those who aren't professionals, but enthusiasts to learn more !! Have a happy and succeeded installing, if you follow my given steps !! :-D

overall great series - however you make an absolute critical error and promote that through your "advice". You MUST have a machine specific Service Manual, guessing and "same-as" stuff is dangerous - ie piston ring placement - 100% incorrect for other machines, you must have a manual and follow it. No excuses these days, all online.

another load of crap !!
