Chain

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.

DrivetrainSuper Bike

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…]

Renthal Rear SprocketsAfter riding your Yamaha R6 on the track and street for a few weeks, months, or years you may be asking yourself eventually “how do I get more power from my R6?”  The answer is easy and relatively cheap in comparison to other modifications that can be done for 1 horespower here or there.

Upgrading to a 520 Chain conversion with an X-Ring type chain can be  easy on the wallet and mechanically straight forward. It is a basic mod for all ranges of skill in the garage.  With a torque wrench, chain splitter, and a basic set of tools you should be able to swap the stock setup for the new gear in about 30 minutes (depending on your skill level, some can turn this into a four hour job).  You will also need to purchase a speedohealer in order compensate for the change in gearing.

What does the 520 chain conversion and new X-Ring chain do for you?  It does give you a significant increase in torque.  More importantly the lighter sprockets weigh less and the X-Ring chain has lower friction which gives you two things.

  • You decreasing the amount of unsprung weight on the motorcycle WikiPedia Definition of Unsprung Weight
  • You reduce the amount of HP that’s lost between the engine and the wheels due to drivetrain loss
  • You will increase available torque at low RPMs (wheelies anyone?)

The new combination of chain and sprocket will increase rear wheel available torque but not produce more engine/crank HP.  If you change the gearing down then you will get more bottom end drive from low speed and vice versa if you gear up you get more top speed.  By using the Gearing Commander you can figure out exactly the combination you desire for your particular riding.  If you need more power out of the corners or need that extra MPH on the top end this is the mod you have been looking for.  Not exactly a 30 Hp increase but it sure can feel like it if you gear it down a couple sprocket teeth!

Tools needed for the job:

$150 for both sprockets & chain
$100 for speedohealer
$50 for chain breaker / riveter

Good luck and ride safe!

Cleaning

First off the best way to lube your chain is to remove it completely.To remove your chain you will need the Motion Pro Chain Tool and a replacement master link. A rear stand will also be very helpful.

If you can, wash it with Kerosene (Yamaha recommends Kerosene BTW), Simple Green, WD-40, or detergent. Apply with a rag and nylon brush. There are other cleaners out there designed exactly for chains. Whatever you use for cleaner make sure you use a non corrosive. If you use something nasty like brake cleaner or gasoline you will damage the o-rings in the chain. Also, if you have a gold chain be sure NOT to use the Castrol Super Clean in the Purple bottle as it will eat the gold off the chain. [click to continue…]
