T3= best 3 wheeler ever. T4= 33hp stock,  lt250 was 31 and a 250r 30. They were completely reversed in handling. The T4 is a terrible handling quad. I always like the power on my friends 87 T4, It was terrible to ride till he got a +2swinger, 2+1 A's and a 2+2 axle and works shocks. Then It was a blast to ride, especially with a Klemm pipe. Kawieriders forum has a tecate section and there are some aftermarket parts being made and 330 big bore stock cylinders using kawi jet ski pistons. I'd like to have a t3 and 4 someday. Iceracer has a T4 and SBLT500 has a really SWEEEEEETTT T3. T3 with a kx500 would be really sweet...
