    Very cool vintage video, Norman, of the world round with sections that look more like ours.

    Re magnetizing flywheel magnets is entirely new to me. Nothing I would ever have thought of. Pretty cool!

    I have decided I need to do the crank seals on my 94 Alp 240. Seals look easy enough to get but I'm not finding a source for gaskets in the US.
    Is there a source I'm over looking or do I need to order from over seas?

    Thank you,
    Joe

    In the event you just can't get gaskets and the ones you have break, a fall-back plan is clean the case halves very well and use a good silicone-based sealer and no gasket. It's possible your center cases are sealer only and no gasket. You can tell by looking at the seam.

    I've used clear silicone 1 for years. I always have it around in a caulk gun tube. It's good to about 500 degrees. I once removed the thick copper head gasket on a TY to correct the squish by reassembling with no gasket. I Scotchbrite cleaned the surfaces and applied a thin skin of silicone 1 to both mating surfaces with quick assembly before the silicone could skin over. Got rid of ping ping ping from way to wide squish and no leaks at all... for years.

    Another thing I do is when the gasket does separate nicely to one side I reassemble with grease. If the gasket on the retained side comes loose in places I back that up with silicone 1 with a tiny screw driver and then grease the second side. Or you can silicone 1 both sides if you never intend to break into the cases again. If the gasket comes loose I try to I carefully loosen it with an Exacto knife entirely then reuse the gasket. I have reused gaskets that break in one place but the break is clean. Silicone 1 covers a multitude of foibles!

    Finished up some Teammates bikes, some customer bikes, got some welding and fab work done, worked on my '72 Tin Grille Dodge car hauler....maybe it's time for some Montesa love?

    When I assembled the 304 2 months ago, I literally slapped it together. Didn't even set the points gap, absolutely no clue where the timing is, resistor plug installed that's 2 steps colder than the spec plug (it's what I had on hand). I just wanted to see if it would start, which it did. Reassembled it today, started it and actually warmed it up -

    After it choked-n-smoked on LOTS of mix in the crankcase (gee, wonder how that happened :rolleyes) she warmed up and settled into a nice idle. Never did that since I owned it. Took it out for a quickie spin and, yeah it needs some tuning (shocking!!) but it does run!! Getting closer.....:evil

    After the ignition, I'm considering a Mid-Atlantic OKO carb that I keep hearing about and "retiring" the Amal to shop art......

    I am happy with the oko on the ty.I think my combination of using a yz piston and modded fmf muffler through the pre jetted set up off.He gives you extra jets but if they are not enough he will exchange jets for free.I need to swap mine with him for leaner mains and richer pilots.The float bowl seal is not carb cleaner safe.Cleaned carb because of rust in tank and should have known better as had this happen before.

    Shweet, thanks for the info!! Natrually I moved on from the 304 today, getting a parts list together for Miss Bitters "new" K75C -

    We'll see how a correct plug, correct points gap and some timing makes the old 304 smile..... :D

    When (not if!!) it runs, I'll let you tell Miss Bitters that. :evil

    You sure have a lot of projects going on.I am starting to back down on projects as I will never get every thing I would like no matter how hard I work.It's a bummer because as I get older I am just running out of energy.After the Fantic is done my next project will be very focused on a very specific build .Going to pull the frame jig out and buy some chromoly tube.Thinking a 500cc twin in a chromoly frame modeled off a pre aluminum yz250. Most likely will be my last build before I fade out into complete obscurity lol.

    Mid Atlantic also has a a few other things that are cool for people like us.He has venhill cable kits that are excellent quality. They come with a big variation of ends so you can fit to almost any bike.I ordered cable kits,grips and levers for ty and fantic from him a few days ago.I have the venhill kits on the TY and they are excellent quality .

    I'm limiting projects to sprucing up the 17-year-old KLR 685 for NM exploration rides and Baja - maybe. That's vintage enough for me at the moment :-)

    What a difference (almost) a year makes -

    Properly cleaned and sealed crappy homemade filter did it's job with what, 6 or 8 weekends? The pic was the first "swipe" of the air inlet after the PROPERLY SEALED filter was serviced today. Quite the change, eh? :thumb I'm sure @motobene is quaking in his boots for next weekend (if he shows)..... :lol3

    I'm really hating that old Amal. Time for it to get gently placed on a shelf until the end of time..... :bluduh
