If you want a big hp increase the HD platform may not do this economically, but there will certainly be other models/makes that will give you this. Go try a few and see what puts a smile on your dial..

I had several jap 750 fours from suzuki, yamaha, honda. And the one i liked most to climb on for a weekend cruise was actually the slowest - my old 1977 CB750F Honda with about 67hp. Beautiful old girl - wish I still had that one and not the FZ750 Yamaha etc. It ain't about max speed and hp..

I think you've nailed-it; because he enjoys it so much, he feels that improving it will equal more enjoyment, when really, it 'Is what it Is'. I'm on my 40th bike, SR500 single, its a hoot to ride, with a nice noisey-muffler, very similar to his Harley in that way... (well maybe a bit quicker haha) If you want it faster, have deep-pockets, contact Peter Sales at Total Motorcycles..he could even make you a one-off crank for it

Everyone has their power "requirements" as to what works for you. I have a little KLE 500 adventure bike and am always disappointed when I get on it an turn the throttle after riding the Duke or the RC8. I would love an adventure bike with more power but can't find one I can touch the ground on

chuck one of these into it:

WASH YOUR BLOODY MOUTH OUT.

The fearsum 'shree point shree' is a capable beast which will propel any mooring chain at a ridiculous pace straight to the bottom of Davy Jones' locker.


I had a black one in my VK wagon, manual with an exhaust. sounded great. but did lack a bit of power and the timing gears stripped off of it.
That was the only problem it ever had though.
Except the thrust face on the crank wore off.

I still liked it though. A straight six just sounds good.

My Honda 6 never sheered anything off that i can recall. A 6-1 pipe also made it sound better good... until it dropped a few valves.

Still not a straight six so it does not count.

The missus had a short wheel base Datsun 1200 ute. was a minta.
I wanted to put a Honda s2000 motor in it.
Everyone had done the rotary, sr20 and v8 conversions already so I thought that Honda motor would be a beasty one.

I had a 68 monaro..the first of the 2 door coupes..had a 186 in it...for all of a week...was swapped out for a 400 chev small block bored out to 412 ci and tunnel rammed amongst all the other work running twin 600 holleys about a foot out the bonnet , amounted to 580 rwhp on Dyno , which I will add was a lot 30 yrs ago when I built it. Now THAT sounded better than the 186....

Lose some weight yourself? (-; Power to weight ratio matters.

There isint a police car in the country that can hit the speeds you’re talking about.

And you would have been charged with reckless driving in those circumstances, not given a ticket. Regardless of how lazy the cop was. That’s without getting into the fantasy where they said ‘it’s obvious you’re a good rider by the way you’re driving’

It just didn’t happen.

There use to be police cars that would do that speed easily,down our way any how.Yrs ago our local copa was give a twin turbo suparoo,highly chipped.He was scare of it a bit till the local machanic took him for a drive in it on the canel road.The fire siren went one day and our copa was 3 doors up from me.Well that suparoo flu down our street.I thort wtf he will kill himself in it.He never did try it out flat but it wasn't governed,but the machanic said it would do 250-260 ks easily.

not sure if your harley will handle it...or indeed if you already do it...but running decent fuel makes a hell of a difference to smaller motors and cars too for that matter . the BP ultimate98 is a heap better than regular 91 and even super 96 octane...that extra 2 makes a big difference...chainsaws,lawn mowers and outboard motors all love the stuff....I found with wee 6hp four stroke outboard the top end speed was 2-3km more it was a LITTLE harder to start than with 91 and used more fuel but was much more fun to use.
