TAV or centrifugal clutch for drag bike?

[yalipito]

What are the pro's and con's of each? I am currently running a tav on my mini, launching with the tav is great but the shifting is killing the top speed. Running only an 1/8 mi. Top speed has been 53mph.

Disc clutch....and do a search on here for the topic...there are many threads related to your "pros and cons" question.
For instance...http://www.oldminibikes.com/forum/general-minibike-talk/117105-torque-convertor-vs-clutch.html

If you have the money run a Bully or a bit less expensive run a Max Torque Dragon Skin which the go kart guys use. You can change your springs to engage a various engine RPM.
