UPDATE: I have decided to continue this thread as my yearly refresh, which happens over the long winter here.

For background, my goal on the RC51 is different from others on the forum as I'm not a big modder. My primary goal is to have a mint bike, as clean as possible similar to from factory. I looked for and purchased a 04 NH model in late fall of 2012, but it needed some bits to get mint.... a work in progress.

While I'm not mod crazy, I do like basic mods, easy bolt-on / bolt-off stuff. My biggest priority for my RC51 is not only a clean bike, but also the basic mods and to have the OEM parts in possession too. In one of my conversations with Dan Kyle he mentioned how the RC51 was one of the most beautiful looking bikes ever made. I agree. So my homage is being able to have a nice basic mod bike, mint, and all original parts available.

A major aspect to this thread is showing/seeing basic maintenance work and other related stuff. Seeing the RC51 in various states of undress and through progression is always enjoyable imo. And there is some good advice and tips on work in this thread. Hope it helps. Lots of pictures was a priority in this thread. Enjoy!

Great tools to work on the RC51, or any bike.

As for this thread, lets begin.

Original post

I have some time on my hands and winter is here so I'm doing some work on the bike I picked up in October.

The bike was pretty clean but the forks were leaking and that was the impetus for more.

Here are the latest stripper pics. :D

The rivnut tool I used in the one picture to reseat a spinning seat mount in the frame. Worked perfect.

Had to post a pic of the HRC emblem on the right side engine cover. Woot!

More valve adjustment pics.

I took a look at the air filters since the bike was torn down. They are in great shape with little dust (K&Ns). I decided to order stock air filters to replace them. Any thoughts on going back to OEM filters from K&N? I'm still waiting for the OEM filters to come in.

I also decided to take the airbox off to have a look down between the cylinders. You never know what may end up down there. It all looked good.

Put new plugs in. The old ones show the bike was running pretty rich. The old ones didn't seem to be torqued down hardly at all. I put the new ones in to the manual torque specs (13 lbs-ft).

I know there's tons and tons and tons of empirical data showing that K&N fitlers are no good compared to the stock paper ones, but I tried the same thing a little while back and I had a weird "dead spot" in the low rev range so I went back to the K&Ns. When I take my bike to get dyno tuned come spring time I'll probably put the stockers back in. My assumption was that whatever tune was loaded on my PCII at the time didn't like the stock air filters.

OEM paper air filters are the best ones, even better if you remove the mesh. K&N's are garbage.

is it ok for the bikes health if you remove the mesh?
Yes it is fine for the bikes......Just makes sure you are careful when /if you do to remove all the mesh....and do not leave a few strands of it in there. If one or more of those metal strands were to get sucked through, I do not think it would agree with the cylinder walls:eek:;). Best to use a small cut off wheel on a Dremel rotary tool.

More airbox pics.

I like the K&N's so don't get me wrong. They are really built well. But I don't really know if they are worse than stock for performance, or just the same as stock. Let me know!

On another note, here is a pic I took after I got the airbox off. I like the look of the throttle bodies staring back, and how unique the frame is where the ram air literally goes throught the headstock. Love those huge 62mm throttlebodies staring out. :)


Also attached is a pic of what a new top triple clamp looks like compared to a used one. This is why I rarely ever trust used items for sale. :rolleyes:




Here is a pic of the super expensive steering stem tool. Over $200 in Canada.



Bike is ready to go back together for the most part (need stock air filters still).

I also have a line on a local source for a new Shorai battery for the bike. Got onto Shorai from this forum.

Buddy is back on the 26th he will let me use his tire machine to spoon my new Q2's on the new rims...then I have a boat load of stuff to do to the bike. I just emailed the guy with the low mount Sato's will pick them up on the weekend.

I'm also hoping to get the rest of my parts from my cousin before March but those parts are not needed to get the bike up and running.

Got my favourite suit (Arlen Ness) in for a new zipper on one of the calves, damn it's going to be a good season.

Some more pics of how the ram air goes throught the frame headstock. So cool. Also some shots showing how narrow the bike is. :):) Used my hand to show how narrow the twinspars on the frame are. It is so narrow, yet the bike is so heavy. :rolleyes:


Well, I have most of my parts in and I figured I better start putting the bike back together before I forget how. The steering bearings were cleaned and regreased with the honda urea grease, then the triple trees retorqued back to factory specs and the ignition switch reattached. The forks are back on (with a service and new seals), new kill switch, front calipers cleaned, front wheel put on, etc. All torqued and loktited where spec'd. New brake caliper bolts to replace the rusty ones, wiring placed back into factory positions as per the service manual, Suspension settings redialed in, etc, etc, etc. Pics to come.

It's a start. There is more to go. Tomorrow I hope to pick up the air filters and I can do some more.

What air filters are you gonna use.....OEM's??? Please say yes.
Are you going to be doing any suspension upgrades as well ???
This is the department I am focused on right now....half way there....Am saving up again for either the 30mm Nix kit from D.Kyle via LDH or the 25mm from another source.

I'm going to sell my K&N's to someone who can use them and am going back to stock.

No suspension upgrades needed for me. There is no way I can ride the street even close to track pace where I live, and there are no tracks around at all. Stock will be fine for me, unless I get a whack of disposable income (and that may happen at some point in the next year or two).

If I were doing suspension, I'd go racetech for budget (and for the option of not being afraid to throw the bike away at the track), or full Ohlins (but being very afraid of throwing the bike away). No real need for middle ground imo.

Another picture of the new top triple.

Fawk ya. I tracked for a full year on stock Honda suspension and racing tires/slicks (my avatar is on stock suspension). I can pogo around on the street for a while... :);)

Been lazy lately.

I got my air filters in and had to mod one as per another post here. This is good information for people doing air filter changes and I put it in the following thread.
IMPORTANT http://www.rc51forums.com/forums/showthread.php?t=5902&page=2&highlight=filter

I swapped new brake caliper bolts in replacing oxidized (rusted) ones.

I decided to change to new coolant since the bike is apart but haven't done that yet. I did take off the overflow reservoir and cleaned all the gunk out of it. What a mission. You have to be a creative thinker. It looks much better now.

The overflow reservoir is back on the bike and I put new Honda coolant back into the bike (it is now blue, which is an interesting colour). I have to wait to finish the coolant replacement (run the bike and top off the rad and overflow) until the bike is more assembled than it is now.

I lubricated my throttle cables with the unknown tool post. Super slick now. :) Although I did it the lazy man way and slightly damaged the throttle tube. Well, considering it is $20 to replace and I like things perfect I'll order a new one tomorrow. The right way to do this is to take off the airbox if you don't have enough slack in the throttle cables (I didn't). I had previously purchased new grips and I guess I'll put them on now too. I should have listened to myself and done the throttle cable lubing earlier when I had the airbox off (it was back on when I did it). Planning your work when it is optimal in the disassembly steps is important. Put some thought to it. At least my bike wasn't really put much back together. I only had the airbox shell on, and I got it off again in 4 minutes.

I do enjoy a no-deadline bike disassembly for doing bike work once in a while. I find most shops will never do as good a job on anything because they don't know the bike very well and rush to make money. And it costs your lots of money to have someone else do it. I enjoy stripping the bike down on the easy stuff (to put back on). To see the "fruits of your labour" is nice. You can do a general once over, and get some cool disassembly pictures. You also get to know your machine better, which is great if you have any attachment to it (like many RC51 owners). Frankly I haven't been rushing into reassembly yet, because it will be a while before I can ride it and the bike is so rarely disassembled, and it looks so good disassembled.
