Engine

Since I don’t like to reinvent the wheel I have compiled what I think is expert opinions on how to break in your bike. This excerpt is from Mototuneuse.com.

Warning:  This is a very controversial topic !!

I wrote “Break-In Secrets” after successfully applying this method to approximately 300 new engines, all without any problems whatsoever.

Links to this article now appear on hundreds of motorsports discussion forums from all over the world. The reason is that over time, large numbers of people have done a direct comparison between my method and the owner’s manual method, and the news of their success is spreading rapidly.

This How To Guide was written off of a 2000 R6.

The Valves: They are fairly easy really. This is where re-jetting your bike would have helped you, because you will have to take the tank, airbox, carbs, and then some, off the bike. I would say getting the manual is a very good thing for this. I got some helpful info from the board, but there is nothing some good illustration to go with it, so I ended up going and having some stuff copied from my local shops manual. I had to do this, since my manual did not end up coming with the other parts.

After you get the carbs off, you will take a couple minor plastic coverings off so you can see the head(cam) cover. Take your spark plug cables off and take off the cover. You will see the cams and the cam chain. You will need a feeler gauge and you must look at the spec clearances in the manual. Shims are basically small metal pancakes that come in all different sizes. These are what hold your valves in the position they are in. So, when you do a valve job, basically you are just changing shims out. ie changing the size of the shims. I found my clearances to be tight, mostly just in the exhaust, so I went down in the sizes of my shims. Ok, the manual will tell you how to adjust your cams, so they are in the right place for you to measure your clearances. You will have to take the ignition cover off to do this, so you might as well replace the ignition adv. with an adjustable one, and replace that cover gasket and the cam cover gasket as well.

Ok, now that you know the clearences, you unbolt the cams, and lift them up and take the lifters out. The lifters are basicly an upside down bucket that cover your shims. Take those out and then the shim for it. The shim will have a number on it. That is what you must go by to order new ones. After you order the new ones(which the manual will tell you how to order) them you put those in the given slots. Then it’s all about retorquing everything. I didn’t mention this, but you must write down what shims you got and where they are. This way, the next time you go to change them, you will now right away what ones to get. I will make a clearer How To later, so if this is a little confusing don’t worry. Just know that it really isn’t that hard at all, and other than ordering the wrong shims, it’s imposable to screw you’re bike up.

What is the easiest way to get that extra bit of power out of my bike? This is a question we all ask ourselves shortly after getting a new bike. Besides being bolt on products, a pipe and jet kit are two of the easiest high performance parts that add a substantial amount of bhp (back wheel horsepower). You will not need any special tools for this job. Just your standard metric tools. In this install I am going to explain a full system high mount installation.

Both side mids, lowers, and the rear cowling need to be pulled. Next you will need to unbolt the pipe from the header, the bolt on around mid way, and all that’s left is the bolt to your passenger peg. It is nice to have another person hold the pipe as you do this, but it is not necessary. The new pipe attaches in the same manner except for the tail mount. You will need to unbolt the passenger peg and install the accompanying bracket. This bracket is great, because in the case of your bike going down on your pipe side, the bracket will bend and not your subframe. This is why many people decide to drop the passenger pegs and go this rout. If your using the bracket from M4, you might have to do a little dremeling to get the rear cowl to fit around it.

Power can enable you to do a lot more things on your bike without stressing your clutch.

After your cowlings are back on, you are ready to take off the tank and airbox to start on the jet kit. The kit should come with a set of instructions, so I wont go into what that will tell you. Note: I recommend getting a service manual for this operation. This is good so you can relate parts to names, and manuals give good illustrations that you can’t get any where else. Furthermore, it is in the manual that you will find the easiest chronological way of detaching the hoses that connect things like fuel/air to your carbs. Hint: there are a few things that you should know that the manual may not tell you. Getting at your carb’s pipe clamps connecting them to the head is nearly impossible. They are allen bolts and to have any chance of getting at them, you will have to use a swivel head allen assembly. However, it seems the factory did not tighten the cabs down with dyer force, so simply popping them off is easy enough. Once, you have these off, you will have to detach the choke and throttle cables before removal. After you have the carbs out, you will just follow the instructions that accompany the kit.

Pay good attention to the instructions when they say,”Drill out the plugs, but be careful not to drill to far in in risk of damaging the head of the fuel/air mix screw.” The plug is fairly small and doesn’t take much to pull out. If you’ve read this and you have your kit instructions, doing this job will be a cake walk. If you have any questions, post them to the board and I will help you with it. You should not have to pay any more that $625 for a full mount M4 system and no more than 115 for your dynojet jet kit.

My favorite full system exhaust is the Leo Vince.
