1973 850 Mono shock / showa forks.

My acewell showed up yesterday and my clipons. They are so cool. The clipons will work perfectly. The acewell is small and feature packed. I can't wait to wire it up, but that will be a while.

:wink: Jean

PS Which Acewell did you get? I plan on getting the ACE-3250, right now I am trying to find a suitable gas gauge sender so I can add it to my gas tank.

Sorry, pictures take longer than typing.

I got the acewell here. it was cheap and had all the features I wanted.

The clipons came from the bay also. I need to machine the ends of the bars for my mirrors. The adjustability is great.



My 2 Norris cams I got last week. Still trying to figure what they are one is a MAG 10 and the other is a N750R.


Also a picture of the dunstall center stand i'm making from photos.


My now 3" on center carbs. only 1/4" off of my head. I pulled 3/8" out of them.




I havent had much time on the norton this week. Been working on my yamaha, shocks, HID headlight and front brakes.
The block of aluminum is what I started with. I also removed material from the seam in the caliper to make spoke clearance.

Acewell 2853. I plugged into some power. Wow nice and bright, easy to navigate and the clock stays on when you pull the power. I like it.

Kinda binary aren't you, either no pictures or LOTS of pictures, I hope you won't have a binary throttle on that bike :mrgreen:

Jean

If it is binary the tri-link setup will help tame it in the corners!!

Binary means on/off, all or none. Analog mean smoothly varying. The rod links merge it all into one Tao of Handling. Smoothly delicious right up to the point of drifts and slides and beyond into skips and jumps of digital on-off traction. In other bikes and Commando when I get air borne they feel smoother, not my Ms Peel, she is smoother on THE Gravel than when air borne. Its not flippantly I am missionary for rear linkage and stuck with cliche of Flabbergastingly Fabulous and Ya don't know what you are missing out on.

When one or two tires in surface contact the whole thing can dampen and isolate by either directly absorbing or passing through transparently, yet in air the suspension is oscillating the engine vibes buzzing and the rest of bike rattling annoying till the soft smooth flying carpet returns on landing and power planting again.

On moderns as I creep up to the digital traction states it makes me scream AGGH* and back off. On Peel it makes me squeal AHHH!* then give it More!
Might be missing out on "Flabbergastingly Fabulous"!

Eventually valve spring'd Roadholders and triple linkage word may get out and increase the price of Commandos as the tool of choice to spank anything out there up to hp limits, as no need to hardly slow down for turns like everyone else must, but the 125's which just can't enter the digital states that Norton Torquing allows when leaned way TF over wondering how it can take such G loads to even get unstuck for some real road orgasms.

Again I mentions even just lolly gagging along I got a sense of Huge Inertial Mass of Smooth Stability that's "Uncomprehendingly Uncanny".

Norris described the N750D as "All-out Drag, Fuel or Gas, Land Speed Record (COMPLETE Valve Train recommended)". It has 316 degrees duration and .438" lift. Sounds a bit much for a street bike.

Can't help with the MAG 10 grind. No idea what that is.

Ken

Ohhh, why didn't ya say it was the Norris D+ grind as that's Peel first cam to try
Jim Schimdt offeres them now.

The N750R needs work the lift is .400, .350, .370, and .340. Worn and uneaven and the .350 lobe is narfed. The Mag 10 has .380 lift on the exhaust and .360 on the intakes. And it is in good nick. I think that one will be usable for my 900cc twin 36mm flatslide long rod lightweight piston motor.

Hopefully these 750 cams are tamer in bigger engines. Interesting the Mag 10 has more exhaust side lift. That's common in boosted applications but rare in natural aspirated. Your compression ratio needs to be up there to work long duration cams. I'd be interested to experiment with the Mag10 profile someday, if Peel or me can't tolerate the D+/N750R. Cam cores are valuable it just the lobed messed up, can straight forward be recovered and customized. Drive splines and bush ends are problematic expense wise. Btw Peel is now mocked up on tires to fit brakes and pegs and hoses and controls and crash kit and fairing. Still to build a gear box to test fit. Engine machining fitting done, just some details to button up.

My brain's not working the outer lobes are .360 the inners are .380. outers exhaust inners intake. Glad to see your bikes going back together. It's a nice feeling. I am getting excited to get to my wiring and see all the electrical working. Unfortunatly that will be one of the last things.

Ohhh, you too eh, well lucked out its not mis- installed pistons : )
It I get a couple of bolts out or brace cut and trimmed every day or so, I'm making head way. Slap downs have delayed progress to point its indeterminate so just savoring the process, but like mowing a lawn can see some results now.

I get bouts of productivity, then nothing. I could do some real dammage with a few days of uninterupted working on it. That won't happen. So I'll take what I can get. Hopefully i'll finish up my yamaha brakes this week, and I can be done with that project, then focus back on the norton. My wife is going out of town for a week in april, my parents can watch the boys while I work in the shop, should be a good push then.

Right-O, we all must steal the time to work our dream machine treats. When I had real routine office job I'd so little time to diddle or take off. Now I've a real unroutine life but less money to spend on it. Its inspiring to hob nob with others making head way or showing off completing projects. Got Ms Peel about half hung with her 'secret' weapons, she will be different all right but not exactly in hi tech mono shock or altered frame and forks way. More like Jed Clampett's truck, kegs hung on fenders and Jethro putting on a chrome mirror with bootlegger power plant under the hood.

How is the steering lock with that tank and the lower offset forks?
Its looking good, motivational as well as making me unproductive by looking at your pictures at the same time......

Steering lock works well, I have to weld a small plate on the headstock with a square hole. And fab up some steering stops. So faar everything is working out well.

My mistake about the cam data. You wrote N750R and I read N750D. Sorry about that.

The N750R is a slightly milder grind, with 318 degrees duration and .424" of lift. Norris described it as a "Flattrack, Roadrace, Drag, Hot Street (750cc)" application.

Could your MAG 10 marking be MAG 70? Norris had a MAGNUM 70 grind with 316/310 degrees duration and .438/.413" lift. They called it a "Drag, Roadrace (750cc+), Flattrack (750cc), Street (850cc) COmPLETE Valve Train recommended)" cam.

Ken

I'm a little puzzeled by the Mag 10 or 70 cam. A nice guy on ebay has a norris catalog and has been kind enough to look up the info. Mine dosn't match up with any listed. Intake on mine is .340" lift and exhaust is .380" lift. nowhere near the drag numbers. Maybee some time ago it was and it has been reground. I need to degree it to try to match it better. I'll try out my new degree wheel this week. The info I recieved on the N750R cam was spot on, concidering it's worn state.

i called Norris a few years ago and they were rather annoyed to be bothered with dead end cam applications they sold off long ago. I'd give MegaCycle a ping as they may have the data handy just not making the particular one. TC may also have a clue about these.
