After reaading al comments, i just have one question
difference betwen (Spectro) heavy duty primary chain case oil and heavy duty gold primary (GPCL) ? better for sporster?
thanks for the info

The oil pours (acts) like 75 weight when cold and like 140 weight when hot. There are two specific temps they test at.

last question: dealer recommends oil and filter change @ 2500 intervals
is ithe same with syntetic oil?
Thanks for your help

I do it at 2500 on all my bikes. It's cheap insurance.

several people said spectro oil makes your clutch to slip
true or false?

If it's a synthetic choice you are talking about it's true as with any other synthetic oil in the primary. You didn't specify which Spectro product you were referring to if it was the synthetic or non synthetic.

heavy duty spectro primary

That's not a synthetic oil. No reason for that to cause a problem with the clutch.

From the Spectro site...

Heavy Duty Primary Chain case Oil
This sheer stable petroleum is designed to withstand the punishment of high loads, and contains special polymers to provide exceptional clutch engagement and temperature stability. Meets full OEM requirements, and should be used according to manufacturer’s instructions. Formulated specifically for Harley® Sportster and Big Twin applications. Low drag, low friction loss SAE 85w viscosity eliminates clutch “drag” and slipping.

A petroleum based gear lubricant with advanced synthetic technology that incorporates the highest shear stability viscosity index improvers to withstand the shearing action of primary chain drives and transmission gears.

I found this statement on Iron Pony and Bobs in reference to the gear lube - thus why I went for this product - It appears not to be correct per the Spectro web site

I think I would go by the Spectro site as opposed to the others.
