i was wondering if any uses a sparks tt pipe for mx? if yes how do you like it.

 

Dan,
I own a Sparks TT pipe and used it in winter for ice riding. I ran it with my 86 engine, less compression than I run for MX, and 15/37 gearing. The thing had NO bottom end whatsoever! Out on the bay of Green Bay we made a track and it was fun as heck, it really reved!

I'm guessing you will need a lot of compression, at least 220 lbs and will have to play with gearing. It will rock on open tracks buy may require a lot of clutch on a tight track. Let me know how it works out, maybe I'll throw mine on for fun one of these days.

A friend of mine runs a TT Sparks pipe on some MX tracks but they are usually wide open tracks.
