Just picked up a stock '02 What mods to do?

Well as the title says, I just picked up an 02 with about 14,000 miles on it. Mostly stock with the exception of new cans, tires, and brakes.

No mods or aftermarket parts have been added. So, I'm trying to come up with a list of needed and or recommended mods.

PAIR valve.
Flapper valve
Power Commander USB
Braided brake lines.


Also looking into the coil stick replacements from CBRs but apparently the plugs we use won't work because of the tips. Anyone find some good numbers that will work, or do I have to buy a $15 plug and grind the tip down?

Anything else that I haven't found or listed?

Also, how fast should the bike crank with a fully charged battery? The battery in my old CBR600 cranks pretty fast, but the one in the RC doesn't seem to spin it that fast. Not sure if that is a function of the motor or the battery is dying.

Work on suspension....suspension....suspension. I know it sound sexy like a performance exhaust but you will be happier on a bike that handles like a dream.

Without hearing this, remember you are turning two huge aluminium slugs over on a heavy crank. It will turn over a bit slower than an I4

Thanks Nori, but it has a brand new Jardine system on it.

Thanks Madbuyer, I know suspension helps but I have to plan my costs out for this thing. Since it will be pleasure riding, and not racing or track days, I want to use my $$ for minor improvements that will make the bike more drivable. (I do most of my riding on the highway) I am sure that at some point I will wind up upgrading the suspension.

I have front SS braided lines and in my opinion money could be spent better elsewhere. I didn't see a big increase in feel as everyone raved about. But this is a pretty subjective. Maybe my riding is just not up the the level of everyone else's.

I think the biggest improvement was the sprockets. I went with 15/41. The other major improvement was my Penske shock and Ohlin valving in the forks. My bike no longer skips over bumps mid corner!!

Personally if it was me i'd be spending cash on service part first before mods, Oil + filter, Air filter(s), Replace ALL the fluids, Plugs etc just to make sure Nothings been missed out in its service life, Check the condition of chain and sprockets etc

Mods are a Personal thing, for example swiftone above says that one of his biggest improvements were fork valving and shock, now swiftone might be a slightly larger Chap than that of your typical japanese rider so he requires that Valving mod to handle his weight better, well...needs it more than me who is the size and weight of a typical japanese rider

Best thing you can Do just now is just ride it, you will then figure out what areas you feel its needing improvement on.

LOL thanks guys. Oil is new. Chain and sprockets look excellent with little to no wear. new brakes front and rear. new tires front and rear. new exhaust. I plan on checking the plugs this weekend along with the coolant. I consider that stuff normal maintenance though.

Also have to schedule the valve inspection for the fall as it has 14,000 miles on it right now.

PS, I'm a large chap. lol I go 270.

A lot depends on what you're end goal is. If you are not going to track days the suspension might not be a priority. For me, general rideability was first. So, I started with a mild gearing change and a PowerCommander to smooth it out and make it more suitable for general riding. If I wanted to race / track day I would upgrade the suspension for sure. I'm over 200 too so we are definitely not the rider they designed it around. It works ok on the street at legal-ish pace but much more and you would want to optimize it.

It's true that it's a personal thing. But I am 153lbs without gear so I am right in the realm of the typical Japanese test rider. Though I don't know the solid history on my forks but it looks like they were service before(don't know how long ago) but forks are probably the most neglected part of maintenance on ANY bike. It's just something that a log of people don't think about. So maybe just a forks overhaul will make a big difference.

O ya, and the other big difference I felt was after I got my valves adjusted. Everything was just smoother. Only 2 valves were out of spec and not by much. I had had 25k miles at the time.
