Re:Over heating/runninh hot 9 Months ago  
I ran Royal Purple for a little while in an EX500. It seemed to fall out of grade much quicker than Mobil1 and Amsoil. I run Amsoil 20W50 V-twin in North Texas. Engine stays quieter longer. +1 on don't ride the clutch at stops. I also blip in neutral in these situations just to flow a little more oil. When the temps get above 95 or so, I will run 89 octane, but I never run higher than that in any of my 3 bikes. They just don't need it.

I do use 93 octane in my bike. It was drilled into me that bikes use only high octane. What year is your Star? Does that play a factor/matter? Pretty much everyone is saying the same thing: AMSOIL or MOBIL1. Whatever happened to the Royal Purple craze? Did I miss the memo?😶 I'll try the bolt test to make sure my oil pump is working. Thanks Shores!

High octane suppresses combustion for high compression engines. Ours is a low compression engine. Folks recommend the synthetic oil with th highest zinc content for our cams. Royal Purple may not have as much as Mobile 1 and Amsoil.

Wait... WHAT??? Wouldn't keeping the plates seperated allow them to cool a bit on a Hot day? Mine have been sticking lately on 90°+ days just lately. I've been keeping the clutch lever pulled with a band when parked after a ride on a hot day. Picked up this tip from MC Cops at a MC rodeo.

If that's a bad practice, hook us All up with some info.

Clutch lever in when not running probably does nothing unless your oil is old/bad/gunk. When running and in gear with clutch handle pulled, the discs are spinning against each other and creating heat. When in neutral and the clutch lever out, the discs are not spinning against each other. I assume they are still spinning as a unit. Correct?

Re:Over heating/runninh hot 9 Months ago  
I run 87 octane in my bike always have, I run 85 octane when I can get it usually in the Sturgis SD area when I am out there, it has no ethanol. I have run 91 in the bike but did not seem to make a difference in the mileage. I have 197 miles on this current tank of gas, hoping to ride tomorrow and fill up before I leave just to check the mileage, most I have gotten this year so far is 193 miles but had to pull the reserve, not so with the current tank of gas. The mileage is a combination of slow and high speed running on the freeway and four lane highways. I also run Mobil 1 V-Twin 20-50 and Mobil 1 75-90 gear lube.

Shores the metal plates in the clutch are a unit toothed internally to engine (to a shaft via the gearbox), while the clutch fiber discs are their own unit toothed externally to the clutch cage that drives the transmission. when you engage the clutch the clutch cage begins to spin via the contact between the two units and the transmission begins to move. so, in a way you are exactly right. hope that helps

Correction, I believe it's the reverse of how I said it, but you get the idea.

You're sick.




Was it the "drilled into me" part?


All that weight on a skinny front tire. That's just wrong.

Yessir. And, as mentioned, if there's too much freeplay in the cable the clutch pack won't separate enough and everything is dragging (excessively) when bike is stopped (but, engine running) and in gear. Hard to find neutral and the bike wants to roll forward if in gear.

Also check your exhaust Manifolds/gaskets mine were leaking and causing excessive amount of heat.
