      thanx, That was a Fear of mine. I did my first stage 2 on my 103 with 20k. kind why i was curious about the runout. I read .03 and tehshoes where just showing tracks. replaced w/ Dual Fuelings. Nervous as all hell once complete.Replaced items: S&S lifters, Smith Bros adjustable pushrods and there " covers " , Star Racing 577 cams w/ koyo bearings. So far so good... read 200 psi both cylinder an I installed a T-Max ECU The most challenging part was TDC starting off seeing the cam chest marks was great. BUT leaking pushrod covers and retaining nut slips caused me to struggle madley to readjust correctly. Various videos where only partially helpful for the process. i know you could produce a better presentation. Thanx again@@socalmotorcycleservices2876"

    Why not do a cylinder leak down test? Will tell you way more than a compression test. Just sayin! Lol.

      We always do compression tests first and since the compression was so low there was no need to do the leak down test. Either way the head has to come off so we Just popped the head and the damage was very obvious.
