Less time than replacing an entire engine when you shove a valve through the piston.I tried 3M fuel injector cleaner 3 times.
It does not nothing better to the start issue
but seems to make the low-rev performance worse each time I add the cleaner.
I'm considering about take the injector out and clean it manualy.
It takes time to do the inspection.
I'll do it when I have enough freetime.
Also, 87 octane is what these bikes are designed to run on. Anything else will hurt performance unless it's tuned for it.
