It appears to show QR on the cam - Quietening Ramp - so .003" in and .005" ex should do it.

Thank you very much.

Showing the timming according to my notes.

camshaft timing Should be set at 11.o.cock to the Crankshaft at TDC Drive side . IE left hand side has this fires first, then the righ hand side after 360 degree had pasted, and four stroke engine fire once every 720 degrees that two turns of the crankshaft, yours anna j

Thank you very much!

Gather the Valve clearences:Inlet Valve: rotating the engine so that the exhaust valve is just commencing to open and adjust the reading to 0.006.Exhaust Valve: rotating the engine so that the intake valve is on the point of closing and adjust the reading to 0.008.

Thanks Gordon, I am currently looking at the original photos I took on the camshaft so as to figure out exactly what numbers it has.

For sure T2219.

Hopefully the picture will show the camshaft marks to look for. You should see QR, X1 and X2 respectively. If your camshaft has no marks or QR, you want .003 and .005 valve clearances. If X1 or X2, I would suggest .006 and .008. Gordon.

Thank you Gordon, The picture shows clearly the different cams. Cheers.

Hello,

I am trying to find a "Degree Plate" file to print out so as to place on the engine and make sure it's all in place but I don't seem to find it available on the website.

Cheers,

Paul.

Here is one you can print out and glue onto mylar. Makes it reusable and long-lasting.

Thank you very much Jonathan! perfect, I have just printed it out, I was about to work on the timming without it. Just in time.

Cheers,

Paul

Paul, what is going on in your picture of the barrels placed on half a crankcase? Are you investigating something there? I have never seen anyone do that.

Hello,

Yes, that is correct. I was making sure that everything was aligned properly before closing the bottom end of the engine.

Cheers,

Mostly, to make sure that the spring at the end of the camshaft was working properly and not too worn off. This way, I could see how far in it had to go in, and if the lobs were centered/aligned.

It's my first Heavy Twin rebuild, and hopefully many more to come!

Thank you Barry! I went to your website and download all the PDF's since I am also working on a couple of Velocette, MAC and MSS.

It's a big help to have the Discs marked like you have done.

According to the Technical Data of the Rebuild Manual I have it shows that the Ignition Timing for the Heavyweight Twins in full advance is 32 degrees.

I double checked the tappets clearance to I = 0.006 and E= 0.008, fueled, prepped the oil lines and she started right up!

Wonderful noise, running solid.

Thank you all for your help. I will do that last touches, adjust chains, top up levels and go for a spin.
