I have a 2006 Streetglide/Fuel injected.&nbsp\\; We put in a 95 kit with KB domed high compession (10.5)&nbsp\\;pistons and 211 cams. &nbsp\\;After break in, it started to make a loud noise (mix between a rattle, tapping and sqeaking sound) in the top end on the front&nbsp\\;cylinder.&nbsp\\;&nbsp\\;It only does this under a load and stops when I back off the gas. &nbsp\\;Does anyone know what this could be?

Detonation.You're going to need a good tune to make that compression ratio work with 211's.What kind of fuel management are you using?

I am using Sunoco 94 octane.&nbsp\\; And I forgot to mention that it has a race tuner.
