Finally got the POR15 sealer late last week, the company I ordered from, was out of stock on the 8 fluid ounce (237 ml) can of sealant .
The sealant was $11.25US, the shipping cost about $12US, a HAZMAT item, flammable, but it still was more cost efficient than getting the motorcycle kit from POR15, it's around $45US locally .
Got the sealant in the tank this afternoon, it was a bit more of an effort to get this tank fully covered as compared to the R65 fuel tank .
I'm going to let it sit for about two weeks to fully cure, I have the tank outside in the sun right now, if you're directly in the sun, the temps are still getting into the mid 90's F here still, air temp in the shade is around 70 F., worked up a sweat working on the oilhead this afternoon .
Removed the alternator drive belt yesterday, took it to the local auto parts stores to see if I could get a non-OEM part for a lower cost, but no luck, put the old belt back on this afternoon, so it looks like I go to the local BMW dealer after work tomorrow to get it .
So, hopefully I'll get the engine fired up for the first time on the Lario, or at least attempt to, before the end of the year .
