i`me planning building another frame,ive got 3 choises of engine,gsxr750 ,kr1s or srx400 .ime stripping the kr1s and give her the tlc that it needs after 5 years of good use(anyone recomend crank rebuilders ?) views and opinions will be well recieved,cheers fred

think SEP of kegworth are handy with a kr crank. i have one, cant comment on how reliable it is as its newish but i hear there good. a trellis tube frame would make an intresting concept for the kr. trick front/rear ends ie tz250 and dymags ect with some rs h***a bodywork would be uber cool. with a trick ignition maybe tz modified to fit could allow further engine development and make for a serious track weapon or poss a class (racing) were restrictions are limited but have to be over x amount of years a bike forgotten era/open 400. a genuine contender for parralell twin tz's? would be fun to try if a little labour intensive/expensive. like the idea btw.

i can`t be that trick,my wage ain`t that good for a fab/weld lad ,it would be 17" wheels ,i like the geometry,i dont like the lack of space around the carbs and airbox,that`l be the number 1 aim ,ease of adjustments.ime just building the base of the jig ,and buying the tube end of may,ile have to look up some of the bimota desighns ive read about on ere in the past
