General 440 Inquiry
05 Aug 2015 09:52
Apologize if this might be in the wrong area, if so please feel free to flame me and move it.
That being said....
I realize I am just starting out and this would be a ways down the road but trying to decide a direction to go. I have my KZ440 and love riding it, sense of freedom I can't get anywhere else as well as a peace and calm to the mind every time I ride it. But, I'm already wishing there was more get up and go, not wanting or trying to do anything ridiculous but not sure if the 440 is really going to have the hp and torque to keep me interested long term. So my question is this, in stock trim its about 30 hp, Pops' SR650 is roughly 60hp and the GPZ 80hp. Is it at all feasible to get a 440cc into the 60+ hp range without going with forced induction/power adder, or do I need to look into a 650-750cc KZ to be getting those figures? Like I said this is a ways off and I am going to get much more seat time and skill before going that route so I don't needlessly put myself into a bad situation.
Thanks for the time,
Irish

The 400/440 is a tough, well made little engine. The 400 is around 30hp and the 440 is something like 40 I think, For a well mannered reliable commuter bike you can find few better. It was never meant to be a performance machine. I owned a later model 440, that had a 6 speed and belt drive, that was a great little machine to get work on and gave me very little trouble.
My point is enjoy your bike for what it is, instead of fighting to make it something its not. I would suggest you put your efforts to another project fills your new found need for speed
A 650/750 is a great place to start, lots of project ready bikes out there and good parts support to make them go. The bigger 4's will always be easiest to make go fast, but they cost a little more...

Hey Tyler,
Thanks for the reply and really appreciate it! My little bike is terrific and it's actually a 6 speed chain drive, wonderful commuter and cruiser like you said and perfect bike to learn on and get seat time in.
I kinda figured a 60+ hp build was a pipe dream but thought it worth asking about. I can find a good project 650 with some luck and patience for $500 or so and think that's likely the route I will go. Will play more with the aesthetic stuff on the 440 until I can afford a project bike (single income family and special needs kiddo makes the budget painfully tight). Really looking to swap out the handlebars and grips, not a fan of the buckhorns honestly and grips aren't great for my smaller hands on the stockers. Plus I can switch the replacements over to the project bike when that comes along and move the original buckhorns back on.

I put a set of Euro style handle bars on mine, handled much better than with the LTD bars.

Re: General 440 Inquiry
05 Aug 2015 16:13Gorgeous 440, Tyler thank you for sharing! And yeah that is pretty much exactly what I am going for, would do mine black though most likely to match my scheme a bit closer. I posted a "wanted" for some super bike bars, see if I get any hits. Ride safe and thanks again TylerTyler wrote: I put a set of Euro style handle bars on mine, handled much better than with the LTD bars.

Some 440's are not in as nice condition as the one you've shared here man
. I love these bikes. I've made mine a project because I get more thrill out of the puttering around than distance. For distance and highway, I'll be thinking similarly and looking the 650/750 route. There's some sweet ideas for 750's on this site! In the meantime, enjoy your 440! There's just something about these 2 cylinder kawis. I see in the pic that you have a belt drive cover on. Did you do a conversion to chain? As a guy with the belt still on, I am curious if you did as to how you did it
. Welcome btw!


As long as I get to learn something, I'm happy!

Hey JBosh,
Thanks for the welcome and the kind words always appreciated! I am pretty much set on letting this thing by 98% stock and just riding and enjoying it but I do want to change a couple things up, putting on a set of super bike bars, changing the cables and hoses over to shorten them up (thanks to the awesome brothers that pointed that out to me in another thread!), and then I want to put some different grips and some bar end mirrors on it to clean it up for how I like it, then ride the piss out of it for a year or so until I can afford my own bike and project.
To answer your question I am not sure, I know very little about the bike. Truth be told here is the story behind it (WARNING: long winded rambling coming up.....)
Several months back after Pops had already started buying and rebuilding old KZ bikes (Ajsfirehawk on here, just stumbled across the fact he is a member here today



So long story short(er), my Kz is technically Pops' bike, but mine to ride when I want and lives at his place since our townhome doesn't have any carport or garage. Couple pics from the trip..... bike alone, 3 generations of my son, myself and Pops and then just my son and me.



Thanks for reading,
