Hi, I have an 2004 RC51 nicky edition. I have a nice racing tail, power commander, yoshi pips, and nice good brakes. tires are good, chain is good, sprockets are good and plugs as well. what else can I add for performance and more speed and power?????? any suggestions guys??

I was thinking to put an HID lights but I heard that it might melt the fairing, is that true?? I was planning to put HID 8000K
does that affect the bike or melt it???

thanks for help guys.

"Performance" is kind of vague...more horsepower out of the RC isn't easy or cheap although the airbox is always a good modification. Other than the airbox the obvious things are gearing, suspension and wheels.

HID's burn cooler than the stock bulbs so melting won't be an issue, but using them in the stock housing without projectors is going to blind everybody. Plus, 8k is going to be really blue which kind of defeats the whole reason for having them. Go 5k to have the most usable light........ unless you want to look like all the college kids in their jacked up F350's with purple lights

ChipG, thanks for the information. so its cooler?? I thought it gives more heat, but thats a good news and yes 5000K or 6000K are the best lights. I dont care if people are getting blind, people cant see me! they are dumb and I was about to die!

5.4, I have K&N filter, so what u mean by air box, can u explain more please and give me some names??

watskoooo, I have michellen wheels which are very good and suspension in very expensive so lets forget about this one lol, what about gearing? tell me more about it, what u think i can add for gearing??

For the airbox, google "thorsten airbox rc51" or "turnone airbox rc51"

I meant lighter wheels, not tires, but they are spendier...

Stock gearing is 16/40, lowering it to 15/41 is pretty common, gives you more drive and doesn't really hurt top speed very much, especially on the street.

I'm running 15/41 and I have to MAKE my bike wheelie. The speedo will be off if you don't use a speedo healer , and that's the only downside that I can see.

Front sprockets are $20-$45, rears are $60-$90 depending on what kind you get, but it's a good idea to get a new chain to go with new sprockets.

Don't have to get a chain, it's just generally better to do sprokets and chain together. It's not hard to change your own sprokets, then it will be the price I gave you:)

Kinda lost me for a minute. To lower the gearing, use a smaller front sprocket and a larger rear. 15/41 is what I run. Lowering the bike ruins the handling

You can go down 1 tooth in the front if you don't want to do both. Will make it a little quicker. Going up in the rear alone will make your chain too short

You don't *have* to change front and rear at the same time. If they are reasonably new, you probably wouldn't hurt anything by swapping out one or the other. One thing to keep in mind is -1 in the front is the same as +3 in the rear, so 15/40 is pretty much the same as 16/43. Depending on your chain, you can usually change 1 tooth up or down on a sprocket without needing a different size chain.

I'm running 15/41 on the track and 15/42 on the street.
