Trans concerns

[HTC'sFLSTC]

I have an 07 Heritage Classic. I have Mobil 1 V-Twin in the crank and Syn-3 in the trans and primary. I've been looking for Spectro and have emailed the company to see what I can do to get some but to no avail. I live in Honolulu, Hawaii and we aint got none. What would be a suitable substitute for the primary and trans?

Agree with Hobbit. Get the mobil 1 75/90 or 75/140 depending on the temps you ride in but the syn 3 in the trans isn't good.

Thanks for the info. I'll get try the 75/140 Mobil because it meets or exceeds H-D specs and I'll talk to the dealers out here to see if they can start handeling to Spectro.
