Hey everyone,

My name's Dave, and I just picked up my first RC51. The bike is a 2002 w/14k miles. I found the bike forsale in mid-Missouri and it was owned by a guy who was the second owner, the first owner was his older brother, so it has always been with them.

Looking at the bike, it's in great shape with a few small "flaws", mostly from lack if mechanical/electrical ability it looks like. (i.e-the wiring for the flush mounts looked a little rough, but it's working properly. And a few mismatched clips/retainers)

I've owned 14 bikes, dirt and street, and have always maintained and repaired my own, so I'm familiar with most of the maintenance requirements, etc. I am just not very familiar with this exact bike though. That's why I'm here.

This weekend I am going to strip the bike down and go through it. The previous guy polished the frame/swingarm. So I'm going to strip it down and repaint those back the original black color. While I have it down, I was also planning on checking all the suspension bearings and bushing; pulling the forks off the inspect/lube the steering stem bearings; performing an oil change; plugs; and possibly checking my valve clearance.

Is there anything "bike specific" that I should look for while it's apart?

Also, the bike has a set of Jardine high-mount carbon slip-ons. They look cool and sound nice,....but they don't allow passenger pegs and I would like the the option of putting a lady friend on back here and there. Does anyone know if I can "swap" out the mid-pipes and make these standard mount pipes. If not, I may have to look at ordering a different set.

Thanks in advance.

Coolant leaks stains, etched oil site glass (For those who don't change the oil!) Burnt or melted fairings (aftermarkets are rampant!)


Clutch fluid/brake fluid color, steering head bearings- check for movement, "clicking".


The one item that routinely goes bad is the Fuel Pipe Regulator (FPR), keep on of those on the shelf.

Other than that keeps the fluids changed service to listed intervals in the manual, clean and adjust the chain/sprockets, you should be good.

Welcome to the forum.
It's fine to swap midpipes. And cans. Whatever works for you, but hopefully you have a power commander, so you can run the appropriate fuel map.
A couple bike specific things to check, that I can think of:

1.rad mounts and hoses-Our engines vibrate plenty, check the condition of both your rad mounts. They tend to crack if let go. I like to check the radiator/hose clamps on a *new to me* bike also.
2.overflow tube of waterpump-theres a single small drain-hose on the right side front of the bike that leads to the waterpump. That's the waterpump inspection hose, it should show zero sign of any leakage. When the pump bearing goes out, it leaks there. 1st picture.
3.operating temp of 174-183 & fine to go up to 220: That's where the thermostat opens up and it's common to see temps of 220-225 in the hot summer. Any hotter than that and you need to look into it. I can't remember the max temp but I think it may be as high as 256? Don't quote me on that.
4.gasline hose routings: Check that all these hoses are routed correctly, or they cause problems... 2nd and 3rd picture.
5.wiring/harness routings under the tank: A common problem we've all had here, lowering the tank after service, and wind up with a pinched wire or hose.
6.hydraulic clutch DOT4: Don't know if you had hydraulic clutch before, but ONLY DOT4. Do yourself a huge favor and flush it.
7.throttlebody boots: When you get your tank raised, check the upper and lower clamps on both throttlebody boots. They have a tendency to loosen.
8.Get your proper rider sag set, and adjust your compression and rebound appropriately. Fresh fork oil is always nice.

Hope that helps.

Download the repair manual for the RC51 as well - it's online (free), run a search on the forum and you'll find a link to it...

Funny... I just read jondog9's post and my immediate response was.... "Oh Crap! Really? Is that so?... Man! Now I gotta go home and check all of that sh#t!"...LOL!!!

... Best part? I've had my '02 RC51 since 2006 and have never thought about most of that stuff!

:D :D
And I'm just getting started! That's just the easy stuff to look at. There's more, plenty more! :p

Check the vent line...a pinched one can mean you will soon have a gas tank that looks like it came off of a stunt bike.:eek:

That's true. Didn't happen to me, but at some point I routed the vent tube wrong, and it ended up getting backwards and slipping down till it eventually hit the exhaust and melted shut :eek: I caught it pretty quick though, saw it dangling when checking tires. ;)

Hey guys,..Thanks for the combined knowledge. I stripped the bike down, went through it and got rid of the polished frame/swingarm and painted it black. I've also ordered RC51 Parts passneger footpeg relocators (yet to be installed).

I do have one hick-up. In low RPMs, around 1500-1800 while in gear and riding, the bike is a little "rough", like the fuel mixture may be off. Granted, this thing doesn't have a power commander yet and it had the Jardine slip-ons installed. This may be causing the issue, but it is the only place the hick-up happens. The only time I notice it, is on base when I have to adhere to the 20-30mph zones.

But, here's a picture of how she sits now. I also came up with my own "tail tidy" kit. I made it look close to the Works Comp kit. It turned out decent, but I think I may end up ordered their kit anyways because it looks a little more "finished" compared to what I created real quick in the garage.

That low rpm thing is on all of the Rcs....they like to eat you know.

A PC will help with a proper map to smooth things out.;)

Lord man. 1500-1800 is barely above idle.
I don't even run my FZ1 below 2000 RPM. Below that it's about time to clutch it and coast.

My RC51 runs great, but it really doesn't like me if I get below 3500 RPM.

Haha I know, I know. It's only through a few area's on base were I have to ride that speed. I guess I'll just keep it in first and keep the RPM's up a bit. I was just curious if it was normal among these bikes.

Yea... No... Don't run it that low. It will chug and lerch and become very angry! They're not made to go slow. There's nothing wrong with it.
