What can you tell from these pics?

I could use your help.

I built an e50 for one of my Magnums a few years ago.

Treats Reed kit - mild porting and case matched

Airsal 72cc head (original)- not the one cut for the Treats Reed Kit

Malossi 4 Petal reed block

Stuffy crank

MLM intake

Mikuni VM20 carb

Treats pipe

Stock points

Has been a great kit and has runs strong for the 500- 750 miles +/- it has been on. Noticed a few puffs of air shooting out and some leaking between head and cylinder. I pulled apart tonight to clean and replace gaskets.

My question: Should I replace the rings while it's off. Is it necessary at all. What can you tell by looking at the pics attached. Does the cylinder Wal look fine. Is there more case matching/porting I should do. Again, this bike runs great with solid pull. I am maxing out at 49MPH with me at 180lbs without issue and comfortably cruise with traffic at 40MPH. What more can or should I do?

Thanks so much,

Dean
