I would go with CT Racing. The ESR kit is on sale right now but someone on here posted a pic of their port work and it looked like chit! Could've been a slip up from ESR but didn't see anymore posts on it saying whether the issues were resolved or what happened.

It was me with the pics of the cylinder. The ports were rough grinded and did not look finished. I sent it back to ESR have more portwork and cleaning, but had to pay to do it. Im waiting to get it back now.

Thanx for the update! I was wondering what happened. Not trying to knock the ESR....just commenting on what I seen.

Yeah, no doubt it was poor work and I spoke to Eddie and told him no one must have insepected it prior to sending it.
