Wiseco ring end gap

sidewayz · 10-19-2010, 12:13 PM

Hey guys, first time using Wiseco pistons. The instructions say minimum gap should be .004 per inch of cylinder diameter. Sooooo if I do this correctly then 3.917 X .004= .015 right?

Im measuring .022 for the top ring WITHOUT any grinding. Im used to CP's not these suckers.. any help would be great!

Thanks

Did the rings come with the pistons? Did you have the bores measured accurately? Are you within specification on piston to wall clearance. Something must be wrong.

Ring came with pistons. I'm measuring the bores tomorrow. I didn't stuff the pistons in just yet. Something doesn't feel right so I'm double checking everything again
