Thanks for your help. I will check the clunk. I didn't think the clunk was the problem, however, i did install a large clunk which is a little heavier than standard and would probably fall forward a little easier.

Where can I buy castor? A hardware store? Any special brand? How much would you add per gallon? Sorry for all the questions as this is new to me.
Will castor in the fuel help with overheating without fowling out all of my plugs and killing engine performance?

Once again thanks.
