Anyone have opinions on which is better for a motocycle?
I have heard that synthetic oil can cause clutch slippage, and is not a good choice.
What about the brand names, meaning which manufacturer has the best product?

I personally use Valvoline Dura Blend (Semi-Synthetic) in my truck...180,000 miles and no problems. Although they do say if you have an oil leak it will make it worse due to the higher viscocity.

I forgot about the "Semi-Synthetics"...
Now that adds more choices.

ok you got me that time,my bad . always get recycled synth or semi . it's been filterred twice :) Sorry Joe I never know where your posting from because I always catch you on the new post category .I meant to answer the first time but theres something about you or your avitar that suggests you can take a joke no matter how early in the morning it is after a friday. IF YOU GET A ferring or faring or however you spell the front windshild & body pannel , you'le look like Prince man . :sim: I got a bike but it's a yamy 185 & i'm embarassed to ride it ,so small but your looks like a 650 or an 850,either way it looks better black than purple buddy :)
I use Amsoil 20w50 V-Twin motorcycle oil in our bike('04 Electra Glide Classic) and never had any problems. I use 75w90 in the transmission and the 20w50 in the primary.
Some people report good results with Mobil 15w50. What you have to be careful with is there are some oils that have additives which will cause problems(i.e. slippage) if used in primary.

I think 125gjoe has a Janpanese bike. Not the same as your Harleys. The motor and transmission use the same crankcase.

i actually use whatever the manufacters recommend, just check out what the dealers sell and find out who makes it. mobil1 is regarded as being one of the best but i think most of the name brands are good, jut change it before it brakes down. that said the car get castrol dino oil, my parents get mobil1 synthetic and the truck gets the motorcraft blend.

As far as cars go(not much experience with bikess) once you start with a synth, you can't go back to regular. As mentioned, cars with leaks(read old cars) don't do well on it. I would recomend the synth, but keep in mind you shouldn't go back to regular (even when cash is tight and it seems so darn tempting to get the lass expensive stuff)

i actually thought this was funny
anyway, i have a 99 frontier and i use synthetic
I think 125gjoe has a Japanese bike. Not the same as your Harleys. The motor and transmission use the same crankcase.If he is using same kind of oil for motor & transmission, he should check into Amsoil. Lots of people use the 20w50 in the engine, primary & transmission of their Harleys.
