Dang , String Bean ( MX099 ) , how tall are you ? My CR450 was very reliable . When the first few came out there was a pin in the shifting mechanism that would bend and stick you in (usually ) second gear . Happened to me on the second lap of a 2 hour harescramble at Gran Prix ( my 2nd race on the bike ) . I was pissed and screamed the balls off the bike , finishing in the trophies . Honda made it right with the pin and I raced it the rest of that season with no engine mechanicals . Did a piston and bore for the next year but it actually didn't need it . The only other major I had was the shock shaft breaking . This was a common problem but Honda wouldn't stand behind that one . Bought a Fox Factory Twin Clicker ( WOW , trick ! An adjustable shock ! ) and never had another DNF because of the bike .
