    I will be doing this at some later...but getting at seals without pulling head will be useful...as it seems they seals can let go very shortly after installing in some cases. Frustration level and blood pressure would go through roof if head had to come off more than once in a few weeks....

    Looks like I may have found a source for M7....as 50mm hex bolt full body thread

    or as all threaded rod....https://m.ebay.com/itm/-1-M7-1-0-x-...1?pageci=dda01935-7710-4482-a19e-90138e2a66c4

    rivercityindustrialsupply Ebay store...will run me about $20 after shipping etc but that's acceptable to me for toolage. Will go with current plate setup first and if that hits a wall, then I have this to fall back on.

    Update on my valve seal job. I did the smoking right side seal using the straight square rod with two long 1/4" bolts threaded through the square rod. It worked ok, but the bolt ends tended to wander off the valve end cap as the spring compressed.
    Ludwig made me a very generous offer to send me out the correct thread M7 adaptor to make his tool. Well, he not only wouldn't accept even postage from me, he actually sent me the whole compressor tool!

    I have just used this to perform the seal replacement on the left side. All went well. That side did not show any engine smoke on throttle blip. Yet the right side, after a test ride, had the spark plug looking grey-ish brown, while before the new seal it was oily black. Now, the Left side plug is looking black, lightly oily...so I suspect the original seal was leaking, just a much smaller amount, not noticeable as exhaust smoke. Both now have KibbleWhite viton seals. And, b/c Ludwig's tool was working so nicely, decided it was time to swap out the original intake springs (which measured under the spec free lengths listed in the manual) for fresh sets (standard type...06-7070 AN part number). Will be doing the exhaust springs tomorrow.

    Exhaust springs now renewed. Took the opportunity to confirm presence/ condition of the insulator washer beneath the exhaust valve spring lower seat. All in good kit. Had some troubles with the rockers stepping off the pushrods while the thin rod temp spindle was in place. Took a bit of fiddling and poking the rod with a long screwdriver to reseat, but got it done. Clearances set. New spindle cover gaskets, new rocker cover gaskets ( silicone rubber reusuables). Job done.
