carb and rejeting? on En500

I bought a new En500 and the dealer tells me it needs to be rejetted or something like that. I'm not close to a mechanic and have no idea what it means. I know the engine bogs down on accessoration when warm or cold.

There not going to charge be due to the warranty I bought, so I assume its real.

What is that? bad gas due to shipment and what do the delears do?

Thanks for any help.

This is strange. You bought a new EN500 and it runs crappy? Has it always run crappy? If this just started after the bike ran good for a while, I'd expect you might have gotten some bad gas or junk in the tank. First off I'd drain the gas from the tank and refill with fresh gas. I'd add 4-5 oz of seafoam and run it for a few minutes to get it into the carbs and then let it sit overnight. Then see how it runs next day. If it's crud in the gas seafoam might completely fix the problem.
Give us more info on the timeline of how this started and maybe anything the could have led up to it.

I agree with Fergy.

If you bought it new and havn't made any changes to it like change the air intake or exhaust then it shouldn't need to be rejetting. More than Likely it would need to be cleaned which is what the seafoam would do.

The dealer might think that the easiest way to fix the problem is to replace the jets with new jets of the same size.

I've made no changes as I refused delivery due to the bogging down while giving it some gas. Hot or cold it does this with 0.8 miles. The service guy agreed something was not right and suggest he "rejet" the carbs (what ever that means) so it there problem.

I just wanted to know what "re-jetting" was? I maybe using the wrong term here.

this isnt a jet size issue.... to me sounds like something is clogging the fuel petcock, and causing the carbs to starve...

Unless you and the Kaw dealership are located at around 12000 feet above sea level, I'm going out on a limb here and saying that the service guy was blowing smoke. Basically, "I'm going to have to rejet the carbs" means "I don't have any idea what might be wrong, but I'll bet I'll sound technical to this guy if I say I need to rejet the carbs". A bran new bike obviously has been assembled wrong or something left undone somewhere to cause that. The carbs come pre-assembled and are just installed on the bike. I'm sure there's a 1 in a million chance that the main jets are wrong, but I doubt it. I'd be interested in what they "really" find that's causing the problem, but I kind of doubt you ever get to know, from this lier.
Good luck!

I had a feeling it was BS but I thought I check it on the forum since I'm not a mechanic. Problems with bikes or cars mechanics have been able to explain it at my level, but not this time.

Thanks for the conformation.
