I lost 5th gear on the old WR426. She's been a good bike, a 2002 that has been faithful. I came to the conclusion that I will have the tranny rebuilt and I found a guy locally to do the work. That takes care of the mechanicals...now for the ergos. I was wondering if anyone has ever made a switch from the 02 plastics and tank to 03-05 and up stuff. If so, was it worth the trouble/cost? I figure the seat would be flatter and a bit more narrow. Also, while the mechanic is in there tearing it up. Is there anyting else I should be replacing? Any common wear items that with 5 years on them I should replace just to be safe? I love the bike, but it wasn't easy deciding to rebuild and put money into my 5year old bike. These things have changed quite a bit over the last couple of years.
