A new US study has found that anti-skid brakes dramatically reduce the chances of a fatal bike crash.
Anti-lock braking systems can reduce the likelihood of a fatal bike crash by 38 per cent, a new US study has found.
The study, by the Insurance Institute for Highway Safety, found that anti-lock brakes dramatically reduced the chances of overturning a bike and crashing.
A separate study, by the affiliated Highway Loss Data Institute, found that insurance claims dropped by 21 per cent for bikes fitted with the technology.
In a report on the study, the president of both organisations, Adrian Lund, says anti-lock brakes are life-savers.
“It’s a way to reduce the chances of overturning a bike and crashing, so it can save lives,” says Lund.
While the introduction of ABS on cars didn’t deliver any noticeable reductions in fatal car accidents, Lund says it’s clear that widespread adoption of the technology on bikes would have a much bigger effect.
“It isn’t surprising that anti-lock brakes are more beneficial on motorcycles than they are on cars because the two-wheelers are so much less stable and it’s this instability that leads to crashes,” he says.
The braking process on a bike is more difficult than a car because the front and rear wheels typically have separate braking systems. The front brakes are more effective for stopping fast, but hitting them too hard can make the front wheel lock up and pitch a rider off the bike.
Lund says that some bikers hold back on the brakes for fear of locking up, only to find they haven’t braked hard enough to avoid a collision.
ABS systems use sensors to adjust the brake pressure continuously, ensuring that the wheels never lock up and the rider can continue to steer in an emergency.
The HLDI study compared insurance losses for 12 brands of bike with and without anti-lock brakes, finding that insurance losses were 21 per cent lower and claim frequency was 19 per cent lower with ABS models.
The IIHS study studied eight brands and found there were 6.6 fatal accidents per 10,000 registered bikes without ABS and 4.1 accidents per 10,000 for bikes with ABS.
In a statement released to coincide with the study findings, local bike insurance specialist Swann Insurance says the studies support its call for more car-like safety items to be included on motorcycles.
SOURCE: R1 start problem
I had the same problem. After throwing all kinds of money at it, like a new battery, new relay, checking the fuses and many other things. I finally took it to a great shop (M Racing in Glendora, CA) and they discovered it was the starter brushes. Now Yamaha sells a rebuild kit for the 06 R1 starters but it's on back order all the way to Japan. Turns out Yamaha Japan knows about this defect and word is it's going to take months before they start producing the rebuild kit again. I'm sure there will not be a "starter recall" as that would cost Yamaha way to much money which is what the worlds all about, right? Anyway, my starter was rebuilt by a mechanic that rebuilds starters and I haven't had no problems with it. Hope this helps and whatever you do, don't take your bike to Montclair Yamaha. Dealerships charge way to much money and don't get the service or quility of work we all deserve.
Be Safe!!!!

Hi There,
Got this from my copy of the Yamaha workshop manual for this model
The YZF-R1 features a self-diagnosing system for the following circuits:
1. throttle position sensor
2. EXUP
3. fuel level indicator light
if any of these circuits are defective their respective condition codes will be displayed on the tachometer when the main switch is set to "ON" (irrespective of whether the engine is running or not)
1. throttle position sensor a) Disconnected b) Short-circuit c) Locked 0 - 3,000rpm
2. EXUP a) Improper connection b) Short-circuit c) Servomotor is locked 0 - 7,000rpm
3. Fuel level indicator light a) Improper connection 0 - 8,000rpm
It looks like you have a problem with the EXUP Valve on yours, probably seized or maybe cables not moving freely
Hope this Helps

hi mate ,,to have black plugs ,the fuel is to rich,, if u no wot your doin matey,, u will have to clean the carbs out 1st,, take carbs off the bike turn them upside down ,,undo the bottoms ,, take out the jets and idle jets ,, and blow threw them so u can see daylight threw the little holes,, clean any brown residue out as well, ,while the tanks off n stuff, one at a time pull the plug cap off ,, unscrew the cap from the ht wire,, and just snip a liitle bit of the wire off ,,just so u can see a copper lookin wire pokin out the inner of the ht wire,, then screw the cap back on ,, and put back on the plug,, try this little service 1st,, if nothing come back in ,,and il tell u the next step,, cheers
