Is there any professional quality motor shops out there to do some extensive porting to my speedwerx 600 mods?

I had bikeman port my 07 cat mod alittle more. It took them for ever to get my cylinders back 8 weeks when they told me it would take 2. good thing it was August . But it went way better than stock speedwerx porting. I had to add a gram to the weights it ran at 9000 rpm when I tried it with the stock n2n 62.5 gram weights. I would say it added about 10hp but thats just my guess they charged me $450 and I paid the shipping. Thats my 2cents.

Are you racing this or trail riding? I havent really heard anything good about bikeman, not to knock them, but from what your saying, if what you say the whole you think 10 hp gain then maybe they arent so bad? I will give them a call, but theres no way im waiting 8 weeks.

I ran it in race form 114 heads on it but free rode alot. There customer service sucks I called every week and had to bug them till it was done. They gave me a discount and t-shirt for waiting so long. Still doesn't justify having my motor ripped apart for 2 months. Rumor has it some of the guys at Bikeman worked for speedwerx and stole speedwerx secrets donno dont care if its ture or not. I was happy with it when I ran it against other ones that had the std porting could pull holeshots and way crisper. Black magic I hear does good work I'll try them some day.
