hi im planning to do a rebuild on my 98wr400f, though im quite torn on what actually to do. i have big plans next year to do a 800km road trip down to the coast, i heard there are problems with the wr transmission, is the any upgrade, or other transmission from another year or style that will fit mine thats potentially strong, more dependable, i don't what to be stranded with tranny problems because i overlooked this section of the rebuild. also how hard is it the get the connecting rod changed out of my crank from a 400 to 426, would anyone recommend against this 426 conversion? is there anything else i should also change in this conversion; i plan to use the 400 crank 426connecting rod 426 piston/cylinder, some light jetting/ plus hotcams topend. anyinfo would be greatly appreiciate. also iive done quite of bit of reading on the matter and still am a little weary of doing this.....looking for a powerfull/reliable, dualsport/offroad bike...is this the way to go?
