You're pushing the envelope. You might get away with it for a long time and you might NOT too.
Single and twin cylinder "long stroke" engines are NOT meant to "scream". Their most efficient power generation is with low to medium end torque.....not screaming horsepower.
If you want to see a small engine that IS designed for screaming high end horsepower, ride a Ninja 250 sometime. I think someone said that the red line was something like 14,000 rpm......and it will scream along at 12,000 all day long.
Like I mentioned before, we've only had two riders come here and report engine failures (not counting things like "no oil"). One liked to make it "scream" before every shift and the other ran his for long periods at 80 or slightly above. Since you seem to be doing both, I wouldn't want to give odds on the longevity of your engine. It was NOT designed to be riden that way. |
Well, you're right on both accounts, Easy... I do rev the bike quite high and also cruise around 70 for extended periods (maybe only 20 minutes around town, but 2 hours if I'm on a trip). This is my first bike, so I may be making some mistakes. Thanks for the input.
