490 kits for Suzuki?

[browny]

hi all
just in the process of buying a 07 rmz 450 with a 490 kit on it.
was wondering if anyone out there has the 490 kit and whether there were
any underlying issues to be aware of.
cheers

staying on the thing may be an issue if a 450 hasnt got enough grunt ?there was a 490 on trade me last year only done a couple of hours guy was selling bike gear helmet and all spares due to recent injury

I assume it's the Athena kit? My general impression of their stuff (having tried an Athena kitted WR290) is they are quality kits. A quick google only shows some issues with jetting after the conversion. That, and the fact it goes from being a typical 450 (i.e. not exactly shy of power) to an arm-stretching animal with the kit.

Seems to be popular with the motard crowd, but as few people outside of the AMA MX1 can really use a 450, I'm not sure what kind of nutcase needs more power on the dirt.

turns out its a 500 kit. they were building motard but after spending 6.5k on it found the power on lift and not at the top needed for motard, after riding it i was well impressed with its unruly power. im 6"2 and about 100 kg so need a big bike ,my 650 berg just doesnt have the handling on the track but hard to keep up with on open ground, so i spose im that nut case. hope it doesnt kill me.
