Maintenance & Technical > KX500 Original
92 K5 with PSI Pipe and Porting question
SteelHorse751:
I should add that watching old videos from the 80s and early 90s of Jobe, Larocco (94 MXDN) Ward (89 MXDN and 92 Washougal) and a few others are what set the hook for me wanting a KX500.
As for my oringinal question about the PSI porting, the guy who has the bike now talked to the original owner and he had the porting done to "make the bike more ridable".
Anyway, I was just hoping someone might have knoweldge of PSI's work and kind of help fill in the missing peice of information.
I will give a report next month when I get to see and ride the bike.
Thanks

Welcome,
I have a 91 and if your soon to be 92 is anything like mine,
Porting or not, you`re in for the ride of a lifetime.
These big bores are monsters to hold onto.
Make sure you respect the power of a 500.
I learned the hard way and bruised more than my ego after I got tossed off the back of it.
:roll:
Have a blast with your new bike.

Thank you crazyoldbastard!
That is the one thing I do remember when I raced the Open bikes a long time ago....respect!
The KX500 is going to be a "new" ride for me having never rode a water cooled/disc braked Open Bike.
I quit racing in the early 80s with my last bike being a 490 Maico. Before that I had a KX420 that I raced before I got the Maico.
The good thing is I still remember what it was like racing the Open Bikes, and being over here I have a good gym (not much else). So once I decided to start racing again and get the KX500, it was good motivation to hit it (the gym). Kind of like enforced 'off season training' if you will.
But as you said....be ready!
I wish I had a reference on the "stock" KX500 engine (have all ready ridden one). Then I could report as to what the bike felt like with the engine work that has been done to it.
( Edit: I have not ridden a KX500 yet. Was trying to say I wish I had so I would have a frame of reference as to what the porting actually did to the power band. Thanks)
The good thing for me is the guy who originally had the bike was a motocrosser. So I am guessing that the work he had done to it was to make the bikes power better suited for a motocross track.
Either way, I guess I'll see next month!!!!!!!!!!!!!!
Thank you.
