I'm really interested in getting my porting done with him... He told me its good for 8 hp and doesn't lose bottom end like some others do! Anybody that has his porting speak up! Worth it?

Lost the top end of my 700 or should I say my son did. I talked with Big John and decided to go with Doo's 670 dual ring pistons. He sent my cylinders out for replating honing and he checked everything himself when it came back. Big John answered more than my share of questions...he is a walking book of knowledge, and one of the nicest business people I have done business with...

Can't go wrong with BJ. He's always trying to find ways to improve even the older motors. I stopped by his shop this summer and he showed me an update to his intake porting for the 840. He didn't even charge me to do it!!!! WTH kind of customer service is that???????

Who's the top three?
LOL. I thought you may ask that question.

The top three port jobs i have seen (but i have not seen them all) are Bender Racing, SLP and Sled Head Racing. The port height is accurate and polished clean, no stone or burn marks anywhere. Real nice finished clean port.

I have not seen the Trygstad work yet.

I have recently seen, Bikeman Performance porting, it was very nice as well. Good luck Ski-B.
