Golden Spectro Heavy Duty Primary Chaincase Oil 1 Quart

I noticed cooler primary temps with this versus just using 20W-50 motorcycle that Harley recommends, and a little smoother clutch enguagement. I think it's doing its job rather well, but it's pricey for what it is.Even AMSOIL is cheaper, which I have in my engine and transmission of my bike, so I'll be going with the AMSOIL primary fluid next time my bike is due for a change.

This is a great product for Harley primarys, recommended by Baker. Can not find a supplier near where i live. The seller is a real good one. For them i rate them the highest possible.

Excellent oil. I have used this in a 2009 street glide with expected results. Noise from the primary was reduced. Spectro has always produced good products.

Used this on my 1000 mile break-in maintenance schedule for my 2012 Sportster 883.-Gear shifts are smooth-Able to locate neutral fairly easily-Didn't hear a difference in noise, but I do have a new bike.-Would recommend to others

its the only lube I have used that keeps my clutch hooked up.. the Harley formula makes it slip. (its modified)I have about 81 ft lbs of torque at 2,000 rpms.

I've been using this for the last four years, love the stuff. The chaincase is quieter, the clutch feels better, and the shifting is smoother. Well worth the money.

Great stuff works well and quiets down the motor.

I was expecting more of a peanut oil type of taste but this stuff is definitely not peanut oil!
