few questions

When i hit over 100+ i seem to get alot of vibration in the bars and back tire,
its not like the bars are bout to slap the tank(not tank slapper) almost seem's like just bad vibration.
My uncle suggested that it seems to be that my tire is out of balance... is he right?


When the bike gets to roughly 6000-8000 RPM i get some good vibrations in the pegs and i believe its cause that is where the max hp/Tq is at. Right?
every other rpm is fine but when i get into that area seems to be more than usual

last question. After riding for a good hour-hour+, the bike gets insanely hot so hot i cant even touch the frame.
And after leaving the bike sitting in the garage for 2 hours the frame is still pretty warm.
so is that normal heat/warmth or does something seem a little to hot then usual? (btw fresh oil change and it was same way before the oil change)


just would like to hear what you think, just looking for some advice

thanks ,
Alex

No there should not be a bunch of vibration (ideas of a bunch will differ). I would get it checked out for sure

I doubt the 6-8k vibs have anything to do with max tq.

Riding for 30 min. is no different than 2 hrs. The bike should only get so hot. The frame is Al. so it will soak up heat. I cant see it being so hot you cant touch it.I can't see it taking 2 hrs. to cool either. You really should get it checked out.

It is possible that what you think is bad vibration is normal. Your bike should be hitting around 220 at times in this heat. I don't even think the fans kick on till a lil over 200.

thats a pimp looking guage cluster...

I hate that bar temp chit...my zx14 has that and it bugs the out of me...in this heat it will reach the top in traffic but if its starts flashing or saying overheat then you got issues...whens the last time your coolant has been flushed? If you cant remember then its probably to long...flush it and add water wetter or engine ice

And as far as your vibration just take it to Motorcycles Unlimited and have them ride it to see if its just in your head or an actual problem...Im sure if the tire pressure is way off (which you should check first) it can cause an uneven wear pretty quick

when i was having that problem it was because my front wheel was bent. you couldnt see it by just looking at it. took it to Motorcycles Unlimited and they put it on a stand and you could see it that it was bent when they would spin it. when i would get at certain speeds i had a lot of vibration (not violent) but enough that if you were taking a corner it was bad and would scare the mess outta you.

also i would say to get the tires balanced....another problem i have had....as well as the cupped front tire.

Agree ^. And I doubt the heat thing will be an issue when it cools down a bit.

When you flush the radiator, use engine ice to refill, not antifreeze.

The Fz6 has a lot of vibration especially with stock handle bars and bar ends at 7k rpms and above. I put grip puppies on mine and it helped a lot. A lot of guys on Fz6-Forum.com are switching to Fz1 bars and putting heavier bar ends. Also, I have heard of people filling bars with silicone to reduce vibration.

Just some thoughts...

Anti freeze does not help the cooling. It is mainly to keep from freezing. There isnt much need for it here. Engine ice or a similar product and distilled water should keep it at least 10 degrees cooler. Also, if it leaks it wont be as slick and will clean up easier.

Grips wont help too much. Heavy bar ends will do more.
