Title: 97 mph
Post by: afritts4u on May 09, 2005, 11:15:57 AM

Just went to Johnson valley OHV with my K5, I have a gps unit and for fun wanted to see how fast I could go. 97mph was it. I know with better areo clotes ext I could gain a few mph. I can not beleive how stable the bike is at that speed too, fells like a street bike.

What was your gearing?  I'm guessing 15/47?  14/45?

I did 91.5MPH on all stock. Just a pipe and silincer.
On 14/47 gears

Thinking of going to 15/47 gearing????

I'd love to brake 100MPH, just to be able to say I did it on a drit bike.

I am running 16/47 with 17" wheels 150 width 70% aspect ratio which is as near as dammit the same as Brians 14/40.

You don't need a very long stretch of road to rev it out.

you are startin to sound like a 4 stroker..... :lol:
I don't know much, but I know one thing is that I gear the bike so its almost topped out by the end of a straight stretch....two teeth on the rear makes a huge difference on a race track......the bike is faster and does better lap times when I gear it more to be on the pipe......the KX500 is a ass kickin mo fo.... then put 17's on it....wow it still makes me smile when I get off it.....I'd like to get another one just for offroad.... :twisted:  I'm ordering a 36 tooth rear and off to the roadrace track I goo.......

OK, I haven't got the highest gearing in the forum (14/38 on a 150/60/18)...

Just curious how you can you fit sprocket like 16 teeth? 14 is the biggest I can fit without tearing the chain guard to pieces. 14 leaves me with 2 mm left to the chain guard.

I take lower screw off of the chain guard and turn guard bit. Then 16 teeth fit just and just to my old -86 KX. I don't know is there difference between -86 and newer engine blocks?

My KX's rear wheel is old Honda RS250 (not orig, Marvic?) 4,5" cast wheel.

My 16 tooth front sprocket fits on Ok, it clears the guard but just fouls the rubber that protects the swingarm but does not touch the aluminium and just wears the rubber till it's no longer a problem.

My bike is a 90 model if that makes any difference :?
