added some Renthal bars after bending the oems(dropped it for the first time!) now,I have a fairly bad vibration,especially at 45 mph...it basically tingles from my hands to my elbows..is it due to much thicker bars?

 

I have nearly zero vibration after putting on Cyrca Pro-bend handguards with RICOR Vibranators with bar-end weights. The bike feels like a much larger bike now, since this setup even dampens out the other non-engine vibrations of off-road riding. I highly recommend the Vibranators...I have them in all my motorcycles....the only problem with them is, once you eliminate the hand vibrations, you can be amazed at how much the footpegs are vibrating!

 

I read where someone filled both ends of the bars with silicone to help dampen the frequency vibration. I'm not experiencing anything like that so I haven't tried it..expensive fix would be to go get a pair of Flexx bars.
