Maintenance & Technical > KX500 Original

Jetting for Glamis?

<< < (2/3) > >>

Paul:
Because the KX500 will run ok on lower octane BUT the engine - acording to my KX500 manual, you got one to i bet :wink: - is designed to run on atleast 95 octane and prefferable 98 and up. Run something over 100 octane and the bike will show you just how powerful it really is :wink:

alan:
Octane does not have any more power it ups the point at which the fuel will detonate under pressure on its own.

Alan :D

Paul:
This is very true... HOWEVER, detonation is the enemy of performance.

An engine designed to run on 100 octane will run on 92 but not to it's potential. I understand that 100 octane will not make your Ugo run 150 miles an hour but it will make your KX500 run cooler, last longer and not have the serious detonation problem that you are going to encounter at Glamis under serious load.

alan:
You are absolutely correct! :D

I have seen so many post arguing about octane and how much more power it would give you!

You should read the post on YZ490.com when I sugested that using an octane boster would be a good idea! Its amazing what sets  people off! :lol:

Thanks for the advise! :)

Alan :D
