I have a 2012 WR450F, which uses the same fuel pump as the FI YZ 450Fs.

 

My fuel pump appears to be boiling my fuel and is so hot that it keeps on going after I shut the engine down.  Details here: http://www.thumperta...ating-when-hot/

 

Anyone experiencing this on their YZ ? 

 

Anyone clean or replace their fuel filter ?  Where is it ?

 

Anyone running a high pressure (> 1.8 bar) rad cap and have or don't have this issue ?

 

Thanks

The radiator cap is completely unrelated to boiling fuel, outside of the fact that the engine can run at higher temperatures with one, and that might allow engine hea to heat the fuel more.

 

Fuel filter replacement is listed in Common Threads, in the index:  http://www.thumperta.../#entry10702600
