heads stage 4
larger exhaust
I was originally going to go 107" but decided to go 113 inch since I was going this far anyway. That is why the stage 4 heads and larger valves are at the bottom of the list. And the cams will be gear driven not chain.
I have a set of Bassani road rage for big bore engines so this is the exhaust I will be using. Test fitted them today and they sound really good. and look great.

What's it all setting you back ... just trying to compare to some of the 120R builds I had been seeing over the past few months ...
Not sure if there was a special on the 120Rs to break into the market ... but they were going for around $5,500 ...
Congrats on the build ... when is it expected to be done ...?

I should be done in 4-5 weeks. Depending parts on hand vs ordering.
Expecting around 110-120 hp with 120-130 tq..
Price is, lets just say you get what you pay for.
I bought this bike just for this. May hit the drag some but mainly just pi**ing of metric guys.
My builder said it will never drop below 100tq..
I am using www.protwin.com
They are about 150 miles away. I got quotes from several and this was the closest to me and they were in the same ball park figure in dollars.
