Chuck, since I only attend TCKC races for fun and not for championship points, it doesn’t make any difference to me that “TaG” is limited to rotax and PRD, as I just tell everyone up front that I’m DQ’d from any points but I’m the fastest SOB on the track and they’re welcome to prove me wrong. ;)
Which they do. :)
Regarding maintenance and tuning, the pumper carbs used by PRD’s, the X30 and the X125t are very simple to tune: Two externally adjusted screws and that’s it. One fuel line. The Tryton carb on the X30 and the X125t (“heavy” version) seems more reliable than the Tilotson–stick in a rebuild kit about every 8 hours.
The X125t also comes with an upgrade radiator suitable for those hot summer day in the Tri Cities. And the one-piece exhaust doesn’t spurt goo all over your suit (yeah!).
I’d definitely pump Jerry for info on his experience with the X30.
