A leaky cap could let water into the fuel tank

Back in October, Honda issued a recall on 2,443 CBR1000RR and  CBR1000RR SP motorcycles due to an issue with the fuel tank. Apparently  there may be a gap between the fuel cap and the filler neck that can let  water into the tank. As we all know, water has an extremely  poor energy density, and tends not to combust except under dire  circumstances. Its introduction into a bike's fuel system can cause loss  of power and stalling which is, as they say in the industry, no bueno.  

“Honda is launching a SAFETY RECALL on all model year 2017  CBR1000RR/RA/S1 motorcycles to replace the fuel cap assembly. If the  fuel cap seal swells, a gap may occur between the fuel tank cap seal and  the fuel filler neck. The gap may allow water to enter the fuel tank  from the outside. If water enters the fuel tank, it may cause engine  stalling. Safety Consequence An engine stall could result in the loss of  power and may increase the risk of a crash. Effective immediately, YOU  MUST NOT SELL any NEW or USED 2017 CBR1000RR/RA/S1 motorcycles: AFFECTED  UNITS All 2017 CBR1000RR/RA/S1.”

That's pretty intense, but ultimately a good call. I know that I  wouldn't want to be leaned over in a hard corner while my engine was  trying to burn water.

The recall officially goes into effect on December 4. Honda will  notify owners, and dealers will change out the fuel caps on any affected  bikes. If a bike already has water in the fuel system, dealers will  replace any parts affected by the water. These repairs will be done free  of charge.
