Probably the best accessory for a motorcycle! The problem with this is when I installed it on my Blackbird, I did it tonight while the Bird was sitting in my hotel room. Not a good place to wrench something like this. Once I got the bar end off and the bar insert out, nothing seemed to fit. After quite a bit of pulling trying to get the new Throttlemeister insert out and put the bike back together with old parts (ie, ABORT!), I seemed to have lined everything up exactly as it needed to be. The Throttlemeister works well now. I haven't had it on the road, but I will in just a short bit. When installing these things, for whomever might want to order one and then pull their bike into their room to install after a night of non- sleep because they're too busy watching to make sure the paint doesn't fall off the bike, here's what I learned. Start with the non-throttle side first. Be prepared to use some of the old hardware until you get to Lowe's/HomeDepot to buy some more washers (first stop this morning). When going to the throttle side, and when you remove the bar insert, don't worry...the bolt isn't stripping no matter what you might think. When you put the bar grommet on, don't set it tightly to the bar's edge....leave a gap where the grip doesn't go over it. When installing the new insert, don't force it in until it stops....it's a bitch to pull back out and probably won't come back out all the way. If you happen to skip the last mentioned step, DON'T PRY THE INSERT BACK OUT USING YOUR LEG TO BRACE THE BIKE....it tends to cause a bike to get off balance and get in the bed with you (ask me how I know)! If you followed the before mentioned step, tighten the throttle side throttlemeister until tight and you'll see how it works. Then make your adjustments by forcing the insert in ever so slightly and making adjustments from there. It looks cool though! Especially the new character marks the Bird has.....DOH!!!! Nothing like having a 550lb Blackbird get into a bed with you @ 3:30am and try to make passionate love....GEEZ!!! I thought I was going to have to call louie to come get this big bitch off me....I heard he's quite versed in these sort of things..... :-)
