Modifying timing cover for mag timing

Has anyone modified their timing cover to allow access to the mag sprocket, to make timing a whole less awful. I have to remove the exhaust and timing cover(and lose the oil) when adjusting timing. Nightmare.
I pretty sure I have seen a timing cover, in a magazine, with the small cover screwed on over the sprocket. Problem is that you have to usually remove the idle pinion... you'd need massive cover OR an adjustable timing sprocket ...
Luckily you don't have to do that often ...

I think that some of the UK models had such a cover, which would fit an Indian engine.

--------- I believe that "Bullet Whisperer" has a photo showing a timing disc attached to the crankshaft (timing side) via an extension through the quill bolt hole ?? ( seen on the MBR forum recently) ---- can you show it for us on here please BW ?? .......Seems like a good tool to have available.

One of the hates I have with the twins, not only do you have to remove the exhaust, you also have to remove the oil filler neck and dump even more oil. I fitted Pazon ignition to my Series 1 Inter and have not had to remove the timing cover since and I can set the timing in a couple of mins. Not that I have had to touch it since setting it up several years ago

Hi Madoc. Never needed it myself but I would imagine the Indian Timing cover would be easy to modify. All that is required is that you carefully hacksaw the end of the bulge off. Make the cut about 2mm or so from the end so the new cap has a nice rounded over the edge shape. Tidy up the cut edge by carfeully filing and then 120 grade wet&dry on a flat block so both the new cut ends are flat and mate neatly. Then drill 2 holes through the new outer cover plate near the edge at 180 spacing to correspond with a suitable area left to receive the 2 new screws. If the metal left around the opening of the new hole in the timing cover is too thin to accept a new tapped hole for the 2 screws you will have to make small threaded pieces that catch over the inside edges of the hole after the screw is inserted into them (L shaped pieces) Better still, weld 2 small pieces of alloy sufficient size and in position to accept and hold the new screws in the new end cover.

You will also need a gasket under the cover as there is lots of oil flying around in this position.

OH DEAR.....DOH!...Forget what I have just said above, I've just checked and I had forgotten the timing screw that is on the corner of the bulge. I would have laid money that the bulge was clear of the screw so the simple job I described is NOT an option
However,....you might be able to drill out a suitable size hole with a circular hole cutter saw (many different diameters available, and a complete set of them is cheap enough and dead useful) You will then need a slightly larger piece of alloy that could be cut (using the next size circular hole cutter possibly) and fix with two or three screws following the same method as I described above. If you want a really good looking job you might be able to dome the new piece of alloy slightly for improved appearance.

Why the need to re-time?.........Why the need to bodge........? When timing is set it is set.......

Bryan, I kept trying to set the timing on my Inter with the K2F mag, could never get it right, fit the Pazon and forget it
