according to the tq plate that was used ,Buy my builder they are out of round,Steve was called for questions to see how the ones he has are.Harley told me to take it to the dealer I purchased to have them checked,Which I did and left them there to be checked,they where going to use there tq plates ,but Harley told my dealer that there has been complaints from others about being out of round ,and a special tq plate needs to be used to check them.This is what I was told from my dealer as they where told by Harley tech support.was supposed to get call from them today about the plates,still have not heard anything.the kit is sitting up at my dealer.The exact words from my dealer ,is we have done many of these kits and no problems put them on and run them,I asked if they where going to check them if I brought the bike to them ,they said they would use them and give me a 1 year warranty.I want my guy to do the build that has been doing my stuff since 2009,The guy I feel comfortable ,with.So far we dont know if they are out of round or not .On his tq plate they are showing they are out of round,he showed my some different type cylinders and how they did ,which were fine.I'm doing what Harley told me to do ,take back to my dealer that I bought the parts from and have them check them,It all came down to Harley saying that this is not the first complaint of them being out of round, with out the harley tq plate, that was mentioned to my dealer, that my dealer does not have,we do not know for sure at this time,waiting to see if my dealer are going to check on tq plates and to see if they get the plates to check my cylinders .So I will ok about doing this build.But as of right now I have not Heard back from anyone.As soon as I know I will post.I'm giving them until Monday to give me an answer ,Or I will follow through on the return.
