Finally at last, Done!

Mel did you have your cylinder head ported? Pauls exhaust is a fine looking system the carp pipe would have probably gave you a few more ponies. I was thinking with the piston and cams you would have had a wee bit more than 204(still a very good number)

No we did not have the heads done. I was shooting for a torque build due the nature of the riding around here. That was one of the reasons to go with the smaller pipe by Paul. I chose a smaller diameter pipe to give the kind of power that I wanted. Neville did choose a grind that was aimed at the goal of torque knowing that high revs and hp was not going to happen.

My expectations were to get around 185 hp so I feel we did than expected. A man has to choose his poison and live with it. The ride is not just about the big numbers.
 
I can tell you that my head, which is ported isn't really waaay different than a stock casting. Mine are all the same (which is part of the point), but not a lot of stock removal on my head. My 2 cent opinion is the Triumph head in stock form looks really well cast. Im sure the full radius valve job and porting would gain a few ponies, but you'd have to wring its head off to get them.

And I work on castings every single long non riding my bike day!

Not to be the negative one, but too much torque on twisty roads might be a little dangerous. Be careful when leaned over not to give her too much power for the rear tire to handle.
BTW congratulations on the outcome, those are impressive numbers. :thumbsup:

Nah Steel, ya got it all wrong :D it's lotsa fun :roll::roll::roll:

On my Trident with a skinny 120 section rear tyre I used to brake hard and slide into corners, then power slide out.

When I got the Rocket I tried to do the same thing ... didn't work.
I hit the brake hard so as to set up a slide into the corner (like drift cars do) but too much rubber, I just stopped ! :banghead:
I had to let the brake off, go forward to the corner then proceed :D

Well said, Bro!
And why I would not worry about a slight loss of torque at the low rpm from an engine build.
This bike is twitchy to control in a hard twisty even in stock form.

I will chime in here, although I have been reluctant to, knowing that DD was using Paul's header I worked out a much different exhaust cam and cam setting, to help cope with the smaller header/secondary pipe. Normally this combination of pistons /cams will do 200hp with one of many larger exhausts, I have been selling these parts for over ten years. NO OTHER CHANGES to the stock engine, apart from a heavy duty clutch. These parts are made to work as described. So I would say the different exhaust cam has helped a lot. 165 torques is not too much, I have low skill, and have ridden Rockets with over 220 Torques, one just has to think before pulling the trigger. If you manage to do an accidental wheelstand at 210 km/h,on a rocket which happened to me once, you will have a learning experience which stays with you. They are a big bike for a skinny guy like me to wrestle.
 
Hey Doc, this sounds like what I'm looking for. Might be getting to work soon on the 07 motor. Did you have that suspension in Stearns? I thought it was pretty smooth then. I would take Nevs advice on the clutch. Get the one @warp9.9 uses. They work. He knows what works and what doesn't. Don't ask him how he knows

Not sure why you'd be reluctant....you have a happy customer, you certainly know this stuff like few do (by observing other is how I learn). I for one am grateful for your contributions.

Beyond that, you proved Paul's exhaust can make great power! Win, win!
