Hello I just recently bought a 98 yzf 400 and the motor was locked up got into it and the top end looks good but I'm gonna need a rod and a few other parts. Anyway question is I heard you can turn it into a 426 for just a little more money but would I have to change my carburetor? has anyone dealt with this personally? And I also heard I could put a 450 carb on it for $400 or so thought it might help with the problems a lot of people have getting it started.. I haven't had a dirt bike in years and I'm very excited to get back on one so all your help, suggestions, comments, and recommendations are welcome and I thank you for each!!
