hi there! i have always been a thumbper talk guest for a year now (philippines) and never had a chance to realy participate and register till recently..
here in our place we usually do these things its bwt common...swapping chasis and engines. i had my yamaha 1988 dt200r engine place on my 1991 kx125 chasis...the 200R engines are bulkier comparing to 125's...so what we did is basically overlap the chasis with a piece of metal were the tank sits and alligned it. it was a success ..the radiator we use is from the kx...i actually race that thing and trailed it for some time now..the idea came up so that i could use the racing suspension on my trail bike engine for dual purpose ... have sold the kx125engine and dt200r chasis..
