Help this guy out folks. I’m not an expert but I know there are people on here who are.
I saw your page on facebook and have been looking around for help, I’d really appreciate it. I own a 1999 R6 that I am having problems with, and would appreciate the help. To start off, I am having major problems with the bike to ignite, It just keeps getting worse, it idles but it takes many tries before it actually starts, recently, I tried somany times it killed my battery cause it wouldnt start.. If i dont ride for a week or longer my battery dies. Recently I borrowed a battery from a buddy of mine with a bike, and my bike started up fine with his battery.
Second when the bike is on, my headlights are dim, once I accelerate they brighten up alot more.. what Im more worried about though its the whole starting problem.. Its a big problem to me.. What do you think this problem is? I have been trying to do some research and it seems to be pointing towards a stator or voltage regulator problem.. I WOULD GREATLY APPRECIATE THE HELP!!!
I recommended this but I know I don’t know enough:

First off you need to know I’m not a Yamaha mechanic. All the knowledge I have comes from working on my 2006 R6 and I never experienced trouble such as yours.

From what your telling me it sounds like you have a bad battery. A new battery with a Battery Tender 021-0123 Battery Tender Junior 12V Battery Charger sounds like it should cure those problems. But I don’t know for sure.

If the battery is good then I can’t imagine another problem other than the stator, which is essentially an alternator.

What do you fellow riders think?

tjUsing certain techniques can greatly increase the longevity and decrease the repair costs of your Yamaha R6. Here are a few of the methods I use to keep my baby in tip top order. I’ve included links to other articles that relate.

The first order of maintaining your motorcycle is not to crash. Ride within your abilities and the constraints of your surroundings.

Since the Yamaha R6 is quite powerful one of the most vulnerable parts to strain is the drive train. This includes the transmission which is a wet clutch lubricated with the engine oil. Simply put, the less stress subject your drive train to the less wear it will have. [click to continue…]

Sorry for the multiple parts. Until I can get off my ass and write this up, or someone does it for me, this will have to suffice.

There are some parts where he isn’t completely clear so I’ll trying clarifying when I can. Feel free to ask questions. In fact, please ask questions.

This is a simple question. The best spark plugs for the Yamaha R6 is the NGK CR10EK Spark Plug. Here is why according to mototuneusa.com.t_16309_01

“One reason the CR9EK’s or CR10EK’s make more power is because they take up more space in the combustion chamber, which increases the compression ratio. The second reason is that the spark is .040” / 1mm deeper into the combustion chamber. I think that increases the burning efficiency at high speeds.

They work so well that Yamaha uses installs them in the R6 from the factory.”

A great oil filter to use is the Mobil 1 M1-108 for 2006+ R6s and Mobil 1 M1-110 for the R6s models.

Expert Village also has some semi informative videos on changing the spark plugs on a 2006+ Yamaha R6. I’m going to use them until I can write my own complete guide. If you want to write one I would LOVE IT!

What have your experiences been with spark plugs?

My 2006 R6 has about 6000 miles on it and has developed this incredibly irritating clicking noise. I know the noise is directly related to engine RPM because I only here it between 3500 and 6000 RPM. This prompted a furious session of internet research on “clicking R6s”. My research was quite enlightening.


This is a sweet bike.

The first thing you should know is that they click for a variety of reasons and your should at least let a dealer listen to the click to ensure it is not something malignant (bad). Don’t just really solely on this post.

It turns out there are quite a few things that cause the clicking. I will the list the ones that I know of. Please add your own in the comments section.

1. Chain tensioner. This is normal. There is no maintenance needed.

2. Valves. If your bike is above 12,000 miles you may need a valve adjustment as they can click slightly when out of adjustment.

3. Fuel injectors. This is harmless and normal.

4. Clutch basket. This one a dealer certainly needs to check out. If you have loose items in your clutch basket it will exponentially increase wear and tear internally. Fortunetly a knowledgable mechanic can dignose these problems relatively easily.

If you know of more causes please add!
