Well worth it. Can't go to the store and buy a bike that rides like that. Beautiful bike, and good job documenting. I know I wish i had done a better job of that in the past....or maybe id rather not know.

That's a heck of a list.

 

[Bud64]

Thank's and yes she's a labor of love.
This is the most expensive build I have ever undertaken, but also the most detailed.

Had to order up a few new parts yesterday, have some play on the rear wheel (wiggle). When I pulled the bearings out and spindles, they looked as if they were from 1968 and never serviced, not good. I guess it was overlooked during the rebuild, was able to get most of the parts from British Cycle ($73), but needed to get the inner spindle sleeve from Steadfast Cycle ($24).
I will need to check the front bearings too after finding this issue.

 

[Bud64]

Replaced both rear bearings and greased everything up nicely and put it all back together, but have an issue. The play is gone (wiggle) on the rear wheel, but when I rotate the wheel it has a tight spot. Not sure what the cause is, will take the wheel off again and see if I can see anything.
Does anyone have an idea, what the cause could be???
Would it be better to switch to the new one piece rear spindle over the stock two pieces?

Well winter work starts again on the old girl. Pulled off the single carb and going over to twin Amal 930 carbs. Looking forward to see how much better the top end performance will be.
Have two resleeved Amal 930 carbs with cables.
But still need to get studs and nuts, manifolds to attach everything together.

 

[Bud64]

So got the manifold from Highway Cycle last Monday and the studs from a local nut and bolt shot. Got some 5/16 coarse x 2" long studs that really worked well.
Now I'm just waiting for some new gaskets to put it all together permanently, did a test fit and everything matted up nicely.

 

[Bud64]

So I got the new old 930 Amal twin carbs installed. Still need to dial them in, but need it to be a little warmer first. I did test fire and they worked.
Here's the pics of them mounted on the bike.
You can see the manifold/spacer first with a breather hose joining the two, next is a thick thermal gasket to keep heat transfusing to the carbs.

Every little helps Bud nice to see it's still going forward sure could do with a bit warmer & dryer weather to get things rolling again

Awesome work, Lars! I hope one day to be able to turn out work like that.

 

[Bud64]

Thanks Cookie, it just takes time.
I've built a few bikes now and I can't say this is going to be my last. This old girl is keeping me busy and I'm always coming up with other ideas for her too. Because of that she will be always going through changes and updates.

 

[Bud64]

Had a few issues to get the girl running with the new carbs.
1st time I tried I couldn't get the revs under 6000, issue was the cables didn't have enough slack.
So swapped out the throttle with the chock cables and they work better. Got the revs down to 2000. Need a bit move playing with the carbs to just get them right.
What's a good idle setting for a 750 Norton with twin carbs????

 

[Cookie]

Went looking on a Norton forum; the general consensus is around 800-1000 rpm idle speed.

 

[Bud64]

Thanks Cookie.

 

[Bud64]

So was at Highway Cycle today and picked up these beauties!!
Burak-Bye racing bells


No they are not new, just gone over a polishing wheel once.

And here they are mounted on the carbs,



Fit like a dream and really sets the look I so wanted to have.

 

[Bud64]

Can't get the bike to idle under 2500 rpms. There is just not enough slack in the cable for the throttle valve to fully sit at the bottom. So, I have removed half an inch of casing from the throttle cable, this has given me now play(slack). It still looks clean and can not be seen, but gives me the function I was missing. I've balanced the slack evenly between the two carbs, so they will open at the same time. Now I just need it to warm up, before I can test the set-up again.
