Hi , just like you the last two pair of Fag from RGM were Indian made, but sincerly , I do not think it could be a problem, if they made them , they must be under FAG control and "kwality" survey (BDM if you read me....!), where I was more upset , was when I had received four conrods bolts described as pirates parts by Andover (have a look to their site ?) coming from RGM, I had complained but without any success except :"they should be OK SIR"........, and as I do not want to take any risk , I just reused the old ones.............
 
HELP NEEDED HELP NEEDED HELP NEEDED

As said above i need help .My timing cover wich i was going to use has been cut up over the years , to chech the chaintension on domi,s . i forgot what it was ,
I have rewelded it back together but it is rather a mess . As one weld was done , another crack showed up .
there is now more weld than original alloy
Has anybody an early commando or late domi timing cover for sale or to swap ?

these are the 3 covertypes i got .As you can see the rh one is rather messed up and will take a lot of work to make it look half decent

this is the head so far
the flanges onto wich the carbs are fixed were remachined so that the monoblocs are sitting as vertical as possible
this left very little material to screw the studs in , especially on the outside studs
that is why i pegged them with splitpennen (if you do not know what those are it is because it is flemish ,i do not know the english fot it , it is a small tube , in steel , split along its lenght

the carbs were modified by Mr Bratby ,no i have no commercial connections with him but he does a first class job , as one can see to wich toleranties he works
 
Gday Lynxsu, its all looking good so far. The pins you mention are called "roll pins", made out of high tensile steel normally, stainless ones are available aswell.

I have been busy with the gearbox , wich is a laydown but with a commando cluster in it
The mainshaft had to be modified because there is no means for it to be pulled up against the inner cover , as on a AMC box
the bottom shaft is the original one (dominator),middle is the modified one (commando) , on top is an original commando .
mods have been measured from where the splines start on the right hand side
normally the play in a laydowm is taken up by a bronze thrust washer between sleeve gear and third pinion in the box (mainschaft) For this the face on the sleeve gear is grinded for the bronze washer
I thought about grinding part of the splines away as on an original laydown but choose to shim it instead .1.3mm had to be added between sleeve gear and 3rd pinion to take up the endplay in the mainshaft

the rest of the bike looks like this , so i think i will have to face defeat for going to the IOM on it in 10 days
the bottm pic shows the self generating ignition pick ups ,

A big thanks to 79x100 for brainstorming (and drinking geuze ) last saterday (sunday you were no good.....)
 
Duh, spring spacers it what I did to solve the Roadholder top out clunk and gain full 6" motion. Valve springs I use were progressive very wimpy for 1/2" but stiffened up more than the fork springs. A weak spring should let it sag to normal and not clatter on full extension. Before us everybody put solid spacers or longer solid bushes in to get the factory hydraulic stop working, but not the extra range.

as one can see , i did go back ti the original lay-out of the box and had the shaft grinded anyway
the bronze thrust washer is in place and kept there by a tiny bit of the splines that are retained (as per original spec)

not a caferacer


as the dogs on the sleeve gear and 3rd cog are closer together on a commando than on a laydown box(smaller inner dia) the bronze washer had to de turned down

not a caferacer


i did not use the original gears (pinions) because they were rather worn so i fitted a commando cluster , as also a commando mainshaft (modified as you know from above ) because that was longer and put the cluth more outward , neccesary because the cases were also wider than domi ones

i am leaving tomorrow for the iom , if any-one sees my bike , please com over so we can have a chat over a pint about Nortons

I think he is talking about what looks like strong magnets on the end of your crakshaft.

Yes, a new looking device on crank to me I don't understand, but then again I only know Combats.
 
yes it is a self generating ignition
so no need for a battery any more
a couple of coils of the alternator are used as pick-ups for the ignition
it is Spanisch-made and i have't tried it out yet but people i talked to used it on all kinds of bikes and seemed very impressed (well i think they were as they all talked spanish but i don't......)
 
lynxnsu, I gotta echo grandpaul ---inspiring!! I have a timing cover, not sure if it's compatible with your cases, I'll dig it out and take some pictures if you still need one. Cj
 
A hard pull clutch is usually the clutch pack height. Going with a new 5 plate 850 clutch will leave you .020 to .030 shorter than the new 4 plate 750. The key is the pressure plate. Get that pack close to the retaining ring slot and it will pull with one strong finger.

Anything else will be a mechanical issue that should be addressed and not ignored.

OK then, a Spanish UFO cordless ignitor. Hope it kicks ass.

I have 3 pressure plate in 3 thickness to chase the stack packing. Slickest thickest one is Al.

i have been working on the front wheel/brake
the inside of the drum was somewhat scored so i machined that out and have done the brakeshoes as well
the lathe was driven at 250rpm and the shoes were 'loaded ' with a feelergauge of 1mm before turning them down at the same diameter as the inside of the drum

i found that if you simply fit the drum on the spindle in the lathe that it tends to vibrate , so i made up 2 cones that are a snug fit over the spindle and actually seize the drum on the spindle by tightning down

now back to the gearbox
 
Nice Ducati with the '79 - 80 black and gold work and the seat and fairing.

Also nice looking Norton with a ??? Ducati single tank ? ???? and Guzzi wheels ?

Can you post a few pictures of these bikes?

And an interesting build too.
