Topic: Phaedrus: CB750 RestoMod - Update: 09/23/21 w/ new video

Brown's may go out of business when you finish this project, you've got to be one of their top customers.

I know you're just kidding, I'm just another job to them. Its actually been nearly 2 years since I sent them anything. But what the hay?     I do have the T shirt.

Is it chrome??

[MCRider]

Clocks and machined parts look great. So it will be 888cc?

Thannks.
Yeah, that's been the size all along. Phaedrus I was a 888cc Powroll kit. Ran wonderfully for 50,000+ miles. 67mm= 888.8cc Too big for stock sleeves.

So I replaced that with 888cc pistons from ARIAS, much nicer slugs.

Wow Ron, that engine is gonna scream. Nice, I can't wait to see you put it back together.

I've been silently hoping for 80hp (mild cam) just to put a number on it. Mike says the OS intakes are good for 6-8 hp, so that'll push me closer to that goal nicely.

Ron,

Looks like you have the reliefs/angles cut on the bottom of the cylinders in the block. I used o-rings from a CB900 for mine to help insure sealing.

No reason you shouldn't get 80hp. I think you'll be pleasantly surprised

Yeah, looks that way to me too. Prior cyls lost them. Got by without but I'll definitely use them and was wondering where/what ORings to use. The CB900 tip should work, I'll order a set. I'll talk to Mike first, wasn't expecting they would be recut.

My FJR had a lot more, my HawkGT has a lot less, enjoy(ed) them both. 80hp; 60 lbft torque seems to be a sweet spot for a real nice ride.

Those "reliefs" are the product of the taper sleeves....nothing was recut. The original sleeves were straight wall (like the sleeves in my 915 engine) thus no gap after boring the cylinder. I will be sealing those with 1194 to prevent oil creep. The cylinders "windowed" on 1/2 and 3/4 but that happens 99% of the time. the cylinder will be painted and I don't think Ron will be riding the bike through extended rain storms. It will all work out fine....it's all under control gentlemen.

Had I known they were still in The Man's hands.....  Thought Ron had them.

No, those pictures wre just to tease me. Taken at Mike's place.

Painting the head and cylinder tomorrow....weather here has sucked with constant light rain for 36 hours. I like to paint outdoors as it stinks up the house even though I'm in the basement. Filled voids where the cam cover meets the the head....small stuff (actually one was big) but it makes a difference. Detail stuff does make a difference.

Understood. Do what you need to do. I'm keeping busy with other things.

Something tells me that Mike has plenty to keep him busy!

Finally got a box of odds and ends for Brown's. Had to find a box the centerstand would fit in.

Took the kickstarter apart, hope I can get it back together. Its in the box for rechroming.

Been experimenting with various heat shrink tubing on some old instruments. The shiny black housing on the pigtail dries and and cracks. I bot some gloss black heat shrink from eBay hope it works on the speedo.

The tach is a never used brand new item. But the pig tail had been coiled around the tach and there it sat in a box for 30+ years getting hard in that shape. Now its time to use it and I'm afraid to straighten it out as it might crack. I soaked it in some Rubber Renew for a few days, then applied a hairdryer heat to it for a few minutes. It softened right up and laid out straight.  The RR may not have been necessary, I think the heat did all the work. But the RR is good longer term I'm sure.

[MCRider]

Update: the pigtail on the tach straightened easliy when heated. But when it cooled it hardened again, maybe harder than before. But at least its going where I want it to go.

It's all done. Fitted the rings today...Holy S.....I have never had to take material off the the oil rails until today. And I mean  a lot. Lots to take off off of the top rings too. Parts look mint.

Thanks Mike. Let me know of any doo dads I need to buy. I bought 8 new piston circlips locally 15mm JIC.

[MCRider]

Were the rings of a different brand, for the 67mm size? Resulting in the unexpected oversizing. I guess its SOP to check for that, but usually not much sizing is required?

Were the original cylinders "windowed"? I never knew one way or t'other.

The rings are from Total Seal. They are generally oversize a bit which is a good thing as you can get the gap you want. The oil rails had about .003 to .004.......you need .015 minimum.
 I'll have to check the old cylinder but like I said it happens most of the time.

[MCRider]

Thanks Mike, just curious. Getting ready to receive... 

[MCRider]

Working on the pigtails to the instruments, mainly the speedo. The gloss black outer covering is cracked in several places. The obvious fix is heat shrink tubing. But the problem has been in getting the right size in plain gloss black. Lots of dull black, and gloss black with lettering.

So I found a 9' piece on eBay but its 1/2 in which on the face seems too big. I bot it anyway. With a heat gun, it shrank up tight on the 5 wire bundle of the speedo. ITs not quite as glossy as OEM but close enough. I didn't shrink it real tight allowing the wires to flex. But if final experiments prove out I'll have some excess to sell.

They're an excellent source of Honda electrical connectors as well; I have one of the crimpers Vintage Connections offers, and it's the business.
