You'll use the mid range every time you ride. Top end, not as often.

 

Any other work done? I got a 16 rgs and she needs a little nudge! Been thinking about the woods 555 or 777, torque curve is impressive on the rocket cam! Gonna look back at woods to compare,I already have a Bassani RR,love it!

 

As far as performance, an SE air cleaner, the Pro Pipe, the 574 Rocket Cam, and a dyno tune. That's plenty for me!

 

I've had mine in a my '05 Fatboy for a year now, noticed a jump in midrange power. Sounds good at idle. I will say though that I have a little top end noise that wasn't there prior to cam change, mainly when ambient air temp is above 70 degrees and the engine is up to temp...may just need slight pushrod adjust.

 

Looking to get chris Revis rocket cams for my 2017 street glide. Which would be the best for my bike?

 

Call up to just shop, good chance Chris will answer, he’ll walk you through what you need.

 

I put one in my '15 RGS and loved it! Unfortunately, I can't give you any advice on an M8.

Chris is in California, so he can't put any details on his web site. Like johnwesley said, give the shop a call. If Chris is there he'll be more than happy to walk you through your decision.
