Making the K5's power more usable??

There many ways here  to make the k5 faster.
Are there tips to make him more usable

This is a nice article from geboers about his 89 RC500.

That power would be great!!!!!

thats a great read and lots of truth there ,,,

[bigbellybob]

that's insane 17,000 for forks 1,000 for a rotor. what was the cost of the hole bike 100,000+?

thats 2000.00 less than i have spent on working on my 3 bikes if i made 5 cents an hour

i,ve got a pic of baileys genuine gp winner rc500
look the tank shaped round the lever
this original bike costs over usd 100.000  back in these days
pic is bit poor but still

Thats wy the AMA ban Factorybikes, there's to much difference.
Today's AMA and MXGP bikes aren't cheep. The first crf450 was $1000.000,- I believe.

Nobody any good ideas?

Doordie's G2 throttle looks good.
 



  Am I so difrent than?

A Steahly 15oz. flywheel weight, and the Moose torque spacer.

Turned my KX500 from "wild and snappy" off the bottom end, into a smooth, controllable beast that has eye watering top end and speed.....
A flywheel weight also lenghtens the peak rpm's from the added spinning engine mass..... try one you will love it!

The two factory teams, Kawasaki and Honda, had widely differing views on making usable power.  Which can be seen today in the two 500's.

Honda chose to reduce reciprocating mass and use cylinder porting and head shaping to deliver power.  Kawasaki's factory bikes, in the US and Europe, increased reciprocating mass and lowered compression to do the same.  Kedrowski's and Larroco's SR500's all had much heavier cranks than what ours are.  With little changes to the cylinders original design.

You're never going to get your KX to run anything like Goebers non power valved, steel sleeved Honda.  But you can add a thicker head gasket and flywheel weight to your KX and make it run similar to Kawasaki's factory machines.

On my K5, I found that reed spacer combined with some intake porting and boysen dual-stage reeds made the most difference in making the power more rideable with no reduction in top end rush.  When I put on the gnarly it hugely enhanced the low, but at the sacrifice of the high. With these mods the power is soo smooth and sweet that when I put on a Steahly FWW I barely nticed it (which surpised the heck out of me - last bike I put one on made it a different bike).  My bike is tuned for MX & single track trails the way I like it - good bottom end and huge midrange blast for short shifting.  A dune pilot would need something different. Cam.

thats funny. on a stock 500 bike,who do you think has a heavyer crank. you'll be surpised.

you hit it on the nail. usable power.

Unless I missed your point, you're asking which 500 has a heavier crank.  There really isn't a surprise there.

My '89 KX crank for example is an anvil.  And Kawasaki increased the mass more still in the years to follow mine.  As a matter of fact the flywheel is also much heavier.  Again, Kawasaki increased the weight of it as well in the early '90s.  There is no secret to be told here.  Kawasaki chose to increase reciprocating mass everywhere to produce a tractable motor.  And they did.

Mick witch

reciprocating mass

you mean a crank with more mass at the outer side??
Same weight but more momenten at high rpm.
Flywheel weight sounds good, but i want a motor that stops reving when you shut the throttle. The down side of 500 2stroke over a 4stroke is braking on hardpack. You Outpower them by lightyears, braking .

Still some good idea's to start with

who has a heavyer crank ?

 kx 500 or cr 500.
