I was a little skeptical of buying this because of the low price but it turned out to be a really great product. Its an impressive piece of gear for only 40 bucks. Throttle actuation/feel is really smooth. I had a little bit of trouble getting the TB throttle cable (the one that came with the TB 88 race head kit) to work as the 90 in this throttle housing takes up such a huge amount of inner cable. I was able to trim off about an inch of the cable jacket off to get the TB cable to work. I highly recommend this upgrade, my buddies who rode my bike with this throttle all want one now hah.
