Wondering if anyone has any experience with this belt drive and voltage regulator? I was all set to order an SRM drive till I read that even with the belt they still want the cavity packed with grease, something that I would like to avoid.

Hi Mike,
Lots of people have run the SRM setup dry,
mine was run dry for several years without problems, I added some grease the last time I had the cover off
Its supposed to aid cooling,
The worst thing you can do is run the belt too tight, the dynamo tends to rotate tightening the belt as the strap is tightened
I use a small clamp to pull the dynamo housing lip against the inner timing case and then tighten the strap,
Belt needs to be able to twist 90 degrees easily when all clamped up
Dynamo regulators unit uses a wider belt than the original SRM , that said I am still running the first belt that came with the kit, probably 20k miles on it

John

Thanks John:
I had some grease migration from the drive cavity into the oil pump area. Not much and due to bad sealing on the gasket but I'd still prefer to run the belt dry.
