Ckau - thanks for that info.
That makes sense. I would almost be willing to bet that my stock howhit head flowed better than the 28/23 taida head (without porting). The passages are larger on the taida head but the area around the valve boss is a lot better on the stock howhit. I base this off the valve porting book I just read and do not know this as fact.
I suspect the taida head has extra material for a porter to shape as they desire?
I learned earlier that part of the engine noise I noticed was coming from the carburetor vibrating and contacting the engine mount at certain rpms. I'm working on a fix. I'm really eager to get it all back together for this warmer weather. My son slung mud on me from his kandi earlier today. It was great.
