Default A couple questions regarding temp and vibration

I'm fairly new to my F4i (2006, 3300 miles). I went for a couple hour ride on the highway through some twisties with a friend who rides a gsxr1000. I noticed that my right hand was going numb and that my bike vibrates pretty baddly through the bars. Is this engine notorious for vibrating? I ride a cr250r that vibrates too, but this one gets to me after a while.

Another question regards my temperature getting way high. My friend and switched bikes for a bit and we stopped to switch back we left our bikes idling. The bikes were probably running for 2 or 3 minutes before we got back on them. Mine was showing 247 and was creeping higher, so i quickly took off to get the temp down. My friend figured my fan isn't working. His 1000 gixer was sitting at a constant 219. Riding down the road my bike rests at 173 or so. I guess i'll have to let it kreep back up and check the fan. Is this high temperature normal for these bikes?

Does your bike have bar ends? You can try looking into some vibration reducing bar ends.

Lol not trying to sound douchy, but your friend figured your fan wasn't working and didn't bother to check/listen for it?

My bike just has the stock metal bar ends on it, and my shorty 2 bros pipe is way to loud to hear a fan. As far as i know the previous owner didn't do any mods besides a pipe and cosmetic things. The motor on my bike vibrates away at almost all rpms. I already did the cam chain tensioner so it's new, but my bike runs like new and is practically new some i'm guessing this vibration is somewhat normal?? My friends gsxr didn't vibrate like this thing. Can anyone else help?

247 = 3 degrees Fahrenheit shy of overheat. Yes, you have a problem. Check your fan then check your coolant. When was the last time it was flushed (or even checked)?

As far as the vibration, assuming nothing is wrong with the bike then its your posture. If you're supporting your upper body with your arms on the bike, you turn your arms and wrists into shock absorbers. All of the vibrations from the road are going to travel thru your hands, up your arms and thru your body. And if you're tight on the bars, you're fighting the bike's self correcting nature.

Do you notice vibration anywhere else besides through the handlebars? If not, it's probably your posture. The GSXR may be different enough that you have a different riding position and don't feel those same vibrations.

If your pipe is too loud to hear the fan, get the bike up to temp and let it idle until it gets up above 225. Then cut the engine. If your fan is working, it should remain on until the temp is back down, your turn the key to off, or your battery dies.
