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.
Less time than replacing an entire engine when you shove a valve through the piston.
Also, 87 octane is what these bikes are designed to run on. Anything else will hurt performance unless it's tuned for it.
Tis better to be thought a fool and remain silent, than to open one's mouth and remove all doubt.
