Thanks...good picture of this item
Will check out the price and such on their website.
On the swing arm....actually, I use 90/140 synthetic. Never have seen a 140 oil and as mine is a bit different set up, than the standard swing arm lube system, question if it would work well it I did find it. Might be too thick. Mine has an old fashitioned "oil cup" on it instead of a grease nipple. Think I got it off some car out of the teens...model T, I think and it was used to fill up and lube something or other. Cup with a cover that you can just fill up. Used to be "grease cups" too, fill with grease and twist a turn before driving, and the grease was forced into the area needing lube...used on chassie parts and water pumps. Sort of forrunner of a grease nipple....anyway.......
I use an oil cup and just fill it up every couple weeks...only problem is the fact the big o rings leak so bad....it all leaks out too fast, not good for the the environment to say the least. The grooves in the cradle, are indeed from the o rings, though. Only solution is much thinker o rings...or X rings, as you mentioned, or to weld and resurface the cradle faces....bummer of a job to get right. Got to find some solution though...hate to see the puddle under the bike. Have seen some other neat systems for lubing the swing arm, reservour with tube to the center bolt etc. All would do just as well as my old oil cup, but if it all leaks out....? Any ideas welcome.
