Topic: Salt Racer CB 750 OZ style

Billy,

I'll be doing the DP315 install 'after I get my parts'. Is your's an actual RC327 or a DP327? I'll try to get the actual specs on it too. The card doesn't read like the advertising. Also says to use .012 lash. Let me know how you do your measuring so we can both do them the same way.

[Bill/BentON Racing]

This what you need?  $ lol!

[Jerry Rxman Griffin aka MuthaF'er]

Gotten a little confusing for both us. I'll call in a little.

[Bill/BentON Racing]

That's a 750F 75/76 530 chain, no oiler, double row bearing. Going out to eat with Ron and Logan 78K high school project guys. Call @ 8:30-9 EST, Bill

[Jerry Rxman Griffin aka MuthaF'er]

Will do.

I was able to see the end of the shaft on my spare engine. It does not have that large hole and it does not have any  threads. It has a smaller tapered hole.

Now the little jobs.
I needed to make up a better breather and catch can and I wanted to leave the starter cover on to stop salt filling up that area so I took the guts out of an old starter and went to cut a piece of alloy tube in its place ....sounds simple but it nearly took me out tonight....been of the tools too long man, I was parting it off to the right length in the lathe, had the speed way to high but didnt bother to change it and nearly finished the parting cut and BAM straight past my left ear man , no joke ...I though #$%* that was close, now I gotta buy another pice of tube tomoz ....bugger , that was close man.........but like a good pilot always says, every landing you walk from is a good landing

phewww, glad to hear you still have another ear left!!!

[Nuffsa Fugginnuff]

This has been one hell of a read. Gets the big 2 thumbs up!

Well Mellow yellow has had a serious upgrade,    the engine back in tonight , plan to tidy up install tonight then on weekend spend some quality time to work on the carby manifolds and a good look at this  power arc ignition.

Time for supplier update !
I got snobbed off by Jim and Ken at cycle X with the ignition  I asked a simple question, nice intro about how good his bike is looking and as he had sorted his ignition out what colour wire to no 4 cylinder and what tacho setting did he use, 
Six times I sent the email with Jim responding once saying he would ask Ken, eventually I said for goodness sake just answer me or formalise things and tell me to piss off so I know where I stand.   So they did ?    said they were too busy to bother Ken
I guess they have short memories as to how much money I spent with them over the last two years,    However I havent.

So I have to say,  just to make a point the best retailers I came across during my project has been Dynoman and Ape;  Both very helpfull , resolved any issues instantly, very professional in workmanship, service and attitude, thanks boys , the other end of the spectrum came M3 Mark and Cycle X Jim, you get there but a lot of head fcuks on the way to take the fun out of it.

If challenged on my statement I will be happy to list the journey but I think you get the picture on how it impacts on me. That is I dont like people taking my money and telling me their  too busy to short out there problems after.   ESPECIALLY when I ask for help nicely   
Anyway happy to get the engine in and move forward.

[Bill/BentON Racing]

Johno, I read it......too bad, but the buck stops with Kenny. I don't think he's been made aware of the situation. He will be today! Kenny won't let you down, his people......  Bet once he's aware you get your issue resolved. We'll see, G'luck, and looking nice, Bill

[bwaller]

Glad to see forward progress. Too bad about the negatives, there are always some of those it seems.

Good luck.

[Bill/BentON Racing]

Yes, it happens. I should say that Jim and Mark and especially Kenny have gone way above for me! Jim, I think should relay the message to Kenny, one way or another. Bill

Aluminum pipe is often softer alloy for bending and forming purposes. If it machines gummy it ain't T6
I too had a bad crash, broke. 40 bux worth of clamping bits on my holder not to mention 2/3 hrs of work. Will try to add pic of carnage.
 Better off to saw it first.

[Old Scrambler]

You may be able to get some help from Power-Arc direct. I sent mine back to Ken but still talk to him and get good advice on other things.

I look at your chassis and see two things that may help top-end speed. One, your shock-springs appear to be tightly wound which indicates a soft or moderate spring rate. I have stiffer springs and inserted a nylon stopper to limit overall travel length.  You should check the 'sag' with your rider on the bike and adjust accordingly. Two..........the clip-ons extend the riders hands and arms into the wind and effectively make him deflect a lot of air. The rider should be able to tuck his elbows quite close to the tank. Could you bend and / or shorten the bars to emulate a speedway-racer?

What type of front fender are using? 

[mick7504]

Good luck johno.
It's been a long journey and a good one.
Mellow Yellow is looking angry man and champing at the bit.

Good call 754 , the alloy supplier said the same thing about thick walled tubing  "use the saw not parting tool its just too dangerous"

[johno]

Worlds wackiest starter     catch can all finished, just got to put in the breather fitting when I know the best angle.
weld one end , the other left for remocal and servicing.

[Retro Rocket]

I like it.... 

[johno]

To seperate the fumes from breather stuffed in some stainless cleaning gear

[Bill/BentON Racing]

K, you go the straight mile for sure....it'll pay off this time!  Bill

Dennis,.....No front fender, just the brace, figure salt goes everywhere why worry,  also this set up is just for testing and I have a 6 inch longer swing arm for the salt, might evan try struts on rear if its smooth enough

[Old Scrambler]

Wet Salt.........damp salt........dry salt..........makes no difference. Without a fender SOME amount of salt will pack the center plugs and the coils. With that narrow tank, it will also hit your rider in the face....especially if he must travel over any non-graded (prepped) salt to exit the track. My minimal fender did very little. We made a cardboard triangle covered with duct-tape to close the frame between the cross-tube and the neck. It worked quite well with zip-tie fasteners. The salt still filled the center plugs making it impossible to change them until I soaked the motor with water to 'float' the salt away.

The salt tends to build onto the bike during slow and medium speeds. I have watched videos of high-speed runs (well over 100 mph) that show the salt build-up being removed but then building again as the bike slows. 

[Jerry Rxman Griffin aka MuthaF'er]

+1!!

And, trying to chip away the caked on baked on salt from between the COOLING fins is a real #$%*! 

[johno]

Right It is time to put on the 32mm  flatslides.
I dummied them up on a spare head and the fuel inlets were interferiing too much so I thought I would make up some manifold tubes with a 5 deg and 7 deg bend between the head rubber manifold and the carbs, the bonus was If I made them 50mm long I wouldnt need ram tubes.
The other issue I had was I wanted 32mm inside diam but as you know the closet available in tube is 34mm.  So when I had the 4 bends put in 34 ID tube the slight bend in the mandril shrunk the ID back to 32mm COOL hey        As per pic

So I thought I had it all planned

[johno]

The buggers fell on, no stress no bother , jiggled the carbs and rubbers a bit, they are not lined up parralell but who cares, they arnt putting pressure on each other and they sit in the japanese cheapo rubbers comfortably. So that will do for me this time , no fancy manifold this time.
