chain...hmmm..loose...but lubed i think..i lubed it about 300 miles ago with chain saver. not since i put it back on the rear sprocket though..also makes noise when i ride it but i always figured it was because it was slapping the swing arm which was why i originally was changing the chain and sprockets.
i actually hand tightened the axle nut after putting the chain back on and forgot to torque it after the test run but took out my trusty torque wrench a bit ago (after you mentioned it) and only had to tighten it a bit to reach 69ft lbs. about 1/10 a turn.
Mobil 1 has a name only. It's quality has significantly decreased. Every engine I have ever put it in has gotten louder because it has a thinner cushion of oil.
And every time I used any grade of mobil 1 my used oil analysis showed higher wear than a conventional oil.
Don't get me wrong,I have 100 quarts of the v-twin 20w-50 and 10w-40 mc oil. As well as about 150 quarts of both mc varieties of amsoil too.
The best bang for buck oil out there for bikes specifying 10w-40 is rotella t-6 5w-40. For the price it cannot be beat and shows great wear numbers in the uoa I have sent in. And because it's a 5w it circulates inside the motor faster,reducing wear,and less parasitic loss because of the cold flow numbers.
Rotella t-5 syn/conventional blend has more zddp in it than the t-6 does(anti-wear agent).
An oil with very high amounts of zddp is castrol defy. It's called defy because it is not conforming to the new API spec. It's being marketed as an oil for old hot rods that have flat tappet cams. I can't wait to try it.
I am doing a test this year on my Harley. I am going to use mobil 1 first,then a run on the vr-1,then amsoil,then royal purple and last will be good old pennzoil yellow bottle.
I am going to run all of them exactly 3000 miles,then drain,taking a sample for a used oil analysis. I am going to put to the test which is the best. I will start a thread and post all of the results. I expect the 2 conventionals to show better wear numbers than the synthetics.
