You're leaving the stock head pipe in place, though?
This: does not say "confidence."
Hey, he said he was "confident".....
On the other hand, he IS asking (I think) for some feedback from those who have been down that road.
We have a local member here who was "confident" with a full system (similar to what I have) until she talked to a "local wrench".......NOW she isn't so "confident"......more like "confused" !
Sometimes you have to wonder how a $375 upgrade can solve all the issues with hot running, poor tuned stock bikes?
I guess you take your chances, pay your $$ and live with what you were so "confident" with.
I'm not on anyone's payroll, I don't care about much about how "low priced" something is, I WILL buy something I believe is quality, price be damned, as long as it works as advertised.
If someone asks me what I run on a bike, I'll tell them. I also tell them what works for me may not work for THEM. But, hey, you asked!
This forum is great for sharing what works and what doesn't. It helped me make decisions on some cams, and that has worked out great for us.
I won't bash any mfg. or shop, I just won't recommend them to my friends and club members.
JMHO, now for a beer!
