The 211's cams running with ported heads, some extra compression and a decent pipe are screamers. I'm convinced that my motor wont see 40K with catastrophic failure.
I get 125 miles around town from filled to low fuel light.....
Its loud and angry through a set of baffled BSS. My upcoming pipe change to a Rinehart Rich Urban Biker Sooper Poseur 2-1 pipe should make for an interesting comparo on the dyno after having it tuned....
I wouldnt be suprised a bit if those Big Shot Staggereds make more HP and dont give up but maybe 2-3 TQ against the Riney....Wouldnt be suprised a bit.
Just to shiny? For my upcoming plans!

here is another good web site to check out. www.harleytechtalk.net it's all about performance from harley's. there are a lot of dyno sheets and a lot of different builds, and a lot of engine builders on there that really know there stuff and and answer about any question.

Guess I'm a ***** :-) I've hit 35 mph in 1st before which must be around 4800 rpms and I've hit 60 mph in 3rd many times. And each time, I'm blown away by the power. Do wish I had a tach sometimes. I think I would push this bike harder if I knew what rpms I was running. Guess I'm still a little concerned to blow my bike up. I know, guys tell me, don't worry, you'll hit the rev limiter, but guess I ain't got the nads to take my $20K investment to the limit.

I swear this build would breathe straight fire down at sealevel. The power loss up here is amazing.

Tjose Big Boyz heads are cheap for the gains they are getting.

I hit 50 in 1st and that's when it bounces the limiter. It's better for me to shift at 45-47 from 1st to 2nd. I hit 75 in 2nd and 95 in 3rd without hitting the limiter. My limiter is set at 6250 rpm. My max HP is at 5800 rpm and still have 105 torque. Gotta hang on!

I did not do a top end rebuild when I installed the cam because I bought the bike used last summer and it only had 1,000+ miles. When it has ~30k miles, it will come apart again. It will need new tensioners then, and while at it, BB for sure - cant wait!!

I have decided to do a t-man kit and take the bike to a 103"
