Correct me if I'm wrong. But 90 weight is better at higher speeds than 80 weight. As far as protecting the parts. And when I was at the parts store a lot of the oils were like 75w- 90 and stuff like that. Should I just look for a 90w.
I would imagine 1/2 on either side. :shrug: or maybe 1/4 inch and then 3/4 inch. I dunno. Try calling one of the companies if no one on here has an answer.
I did a search and it pulled up nothing. I will be needing a new clutch soon and I want to upgrade to one that can hold more torque. Where can I go to find some? I look on partshopper and gefracing.com.
