If you are skeptical just install them without using the tape and if the heat is uneven to the point that it annoys you, pull the grip off and add the tape... should only be a 10 minute fix. 

I didn't use tape during the install and don't notice a difference. I'm just thankful for warm hands! They work so well I had to lower the values for each setting. 
yamaha heated grips on the FJ09 have 2 settings....sweaty hands and complete body ignition.  I had a 10deg C ride in to work the other day and the only thing warm were my hands.
 
 
 

Installed Rox Speed  Antivibration Risers.  I could live without these, as my hands rarely buzz to sleep, but I have noticed that 5-5.5K vibration and it can be bothersome.  Someone else had a problem with the buzz and installed these 2" risers on the OEM mounts and noted no vibration at all.  I had to try them, right?  If I don't like them, as they are making the handlebar post have a rubber link, so they may make the handling vague, I will sell them.  I will give it a go and let you all know what I think.  I also used a 2" high mount left over from when I bought the GPR4 for my FZ 09.  It worked perfect to keep the handlebars in the same location as stock, which I like.  I went ahead and bought these from Rox Speed as they were only $3 more than Revzilla and Cycle Gear, and with free shipping (cut out the middle man). 
 
 Any reviews on the anti vibe risers?  Had a chance to test them out?
