M4 Shorty Slip-on for GSX-R600/750 06-07

M4 Performance Exhaust has released a new slip-on for the 06-07 GSX-R600/750. That's right, you read correct, it's for the 06-07. I like to see companies going back to fill a demand in the market and this is a wonderful looking and sounding slip-on exhaust in my opinion. The super-short muffler tucks away beautifully and works well with the lines of the motorcycle. This slip-on comes with a quite insert installed so the neighbors don't complain about the noise.

K&N Releases "Race Spec" Air Filters for Select Bikes

K&N Engineering, Inc., releases new "Race Spec" OEM replacement type air filters for the 08-09 R6, 09 R1 and 09 GSX-R1000.

KEY FEATURES:
- K&N's RACE SPECIFIC High-Flow Filter Media
- Lowers restriction, increasing horsepower and torque
- Fuel-Management modifications WILL BE necessary.
- Closed-Course Competition Use ONLY.
- Washable & Reusable
- One-Year Limited Warranty
- NOTE: MUST be oiled prior to installation

BMC's had a line of "Race" filters for quite some time now. Is it a little too late in the game for K&N to be releasing a "race spec" filter? I think not.

Most seasoned riders tend to gravitate towards BMC filters as the "must have" product for their sportbikes. I think this very reason is due to BMC's focus on motorcycle filters in the consumer U.S. market and the availability of their "race" version which gives our beloved Sunday-Rossi-wanna-be's a chance to feel sporty. I tend to think the majority of new riders would go for K&N given their huge brand presence there in the USA. Heck, I had a K&N in my 03 R6 when I started riding. I use K&N in my automobiles. Oddly enough, my current 06 R6 breathes through a BMC Track Filter. I guess I think I'm fast - ha ha.

In the end both companies seem to make a good product. BMC Filters are re-usable and washable just like K&N filters but you rarely hear about it. Marketing goes a long way. I've read forum posts such as, "K&N? It's not a car, it's a motorcycle. Go with BMC." Did you know that BMC makes automotive filters as well? You do now.

520 Conversions & Gearing Changes

The term "520 conversion" means a couple of different things to different people. I hope to clarify a few things. First, a 520 conversion doesn't necessarily designate a change in gearing. For most people, the "width" of the chain/sprockets is what we'd refer to as 520, 525, or 530, etc. to make things simple (the technical term is "pitch"). The idea here is less weight on the drive train which is suppose to translate into better performance. Generally 520 sprockets are aluminum (which means they wear down faster) over the stock steel sprockets but they are lighter. A 520 conversion is generally a pretty performance oriented modification for your motorcycle so it really depends on your riding style and what you want to achieve with modifying your drive train before choosing the right set up. Remember, all the components of a chain kit (front sprocket, rear sprocket and chain) need to have the same pitch to work together.

A very popular tweak to the 520 conversion is to chain the gearing of your sprockets or the number of teeth which works miracles on acceleration of middle weight 600/750cc sportbikes. The consensus is that -1/+2, down one tooth from stock on your front sprocket and up two teeth from stock on your rear sprockets, is a good place to begin for most 600's. This is a great set-up for the performance oriented riders as it adds a big bottom end punch (helpful for these newer top end friendly bikes with little bottom end) and will bring you through the rpms/gears very quickly. This adds to the already frenzied 600 attitude but I absolutely love the way it feels. It's not a crime to run -1/+0 if you're just looking for a little boost when commuting or riding with your buddies. -1/+1 is also a popular choice.

I found that some of our customers on the big bikes (1000cc) like to do -1 in front OR +2/+3 in the rear as it lets you gear up, or use a higher gear than you usually would, while riding. This is a great benefit as most of the big bikes do about 100mph in first gear and screaming along at 11,500rpm with a hair trigger throttle and 180hp can be a bit unnerving all while at full lean. The low end is improved for your daily riding as well.

I receive a lot of questions about which brand of sprocket or chain to use. As far as the sprockets go, any hard anodized sprocket will do. Some of our top sellers are Driven, AFAM and Vortex for aluminum 520 sprockets. Front sprockets are generally steel. With chains, like most things in life, you generally get what you pay for so don't skimp on the chain and it will serve you well.

SoloMotoParts.com offers 520 conversion kits that allow you to pick your sprocket and chains in various colors and teeth size to serve your needs. See them for Yamaha, Honda, Suzuki and Kawasaki.

What do I run? I use Driven/AFAM sprockets (-1/+2) with a DID ERV3 chain on my 06 R6 track bike. Also, note that changing your gearing will make your speedometer read wrong. A Speedohealer will fix this.
