I recently installed a muffler insert in my 400 and leaned out the jetting to get some of my power back. Now the bike over heats in real tight terrain. Stock cap is a 1.1. Can I go to a slightly higher pressure cap and if so where can I get one?

Go to your local auto parts store with your stock cap and match it with a standard 16 lb cap off the shelf....Your overheating problem will then be resolved.... I've been racing with a 16 pounder for 3 years with great success. The higher the cap pressure the more it raises the boiling point.
