Reku Posted October 18, 2021 Share Posted October 18, 2021 Hi! I have a Honda cbr 125 from 2013 and the engine no longer revs above 9500 rpm.The spark plug is new and the oil has 1000 kilometers,air filter is almost new and the gasoline filter as well.I never rev the engine to high until it warmed up. Any ideas how I could solve this problem?Thanks! Quote Link to comment Share on other sites More sharing options...

Bianco2564 Posted October 19, 2021 Share Posted October 19, 2021 (edited) A faulty injector makes sense. If you want to get it cleaned professionally , I've used this company before. https://www.asnu.com/ Edited October 19, 2021 by Bianco2564 Quote Link to comment Share on other sites More sharing options...
