Original, 205k on it today, quad race on since around 30k
No issues.

 

I recently just had to have my fuel filter replaced due to cold weather gelling of fuel. 16 degree F is just too cold for untreated fuel I guess. Just seemed to stop up quicker and gave me a low rail pressure code. Ran some cleaner after and replaced the filter. Original injector pump and injectors. 111,459 miles so far. Still have plenty of power, good acceleration, mileage has dropped slightly to about 16.5 average.
