That just about covers it Barry, good job. I would like to add a couple of things. The rule about bearings, gaskets, bolts, etc, being allowed, is not a new rule, or one that has to do with APRA only. It has always been that way, even in the AMA rule book. Page 112 in th current AMA rule book, says this is allowed, and is considered stock. No new news here.....OS, MVVS, Rossi, Webra, etc, were disallowed IN APRA, only because of "SPEED & COST". Yes the TT's are less quality, but also "SLOWER & CHEAPER". The last Thunder Tiger Pro 40 I bought a couple of months ago cost me $65. A lot cheaper than the $120 / $160 other higher quality engines, plus they are faster, and some impossible to get. Personally, I have a lot of respect for the Thunder Tiger Pro 40's, mine have all ran good, and I have "NEVER" been able to wear one out, in the last ten years.......Remember the Golden Rule......Keep the event cheap, simple, & fun, and try to keep the equipment equal in APRA / 424....Thats the secret to it's success..... :sunsmiley
