Did anybody mention the Super Tigre .45? Is it not powerfull or does it have a problem. I think one long bearded poster mentioned recent problems with Thunder Tiger. Seems that most of the problems center around quality control problems during final assembly. Things such as loose screws, cam gears off timing, carb not clamped down, sleeve turned around, missing O ring on the needle valve and the like. If you get one check it out, take the back cover and head off, make sure the sleeve is on right, check for swarf in the crank case, make sure every thing (I mean every thing) is tight and in their proper place.
