Got an issue here. This is my first 4-stroke piston replacement. I have a 300ex. '03. Its time to replace the rings.. so i might as well upgrade the piston. I got a Wiseco 11:1 Standard bore. 4574M07400. came with rings. My original piston was cracked by the way... I was replacing rings originally .. but after i got it apart.. i found the piston was cracked. Since i already had the piston..i just bought a new cylinder (standard bore) honed. old cylinder was gouged out.. deep scratches from the cracked side of the piston. My question on this replacement is the Piston Ring End Gaps. i will not bore you with the math i used to come up with the answer... but i got this.
Top ring gap: .011
second ring gap .014
Oil ring gaps .010
Does this sound right for clearance gaps? or am i doing something wrong. Standard piston & standard bore.
Thank you.
