Well it finally happened.. my first major breakdown
my 2005 TC450 has over 300 hours on it now... was riding a very fun and newly Jumpy Vet Track at Milestone MX on Saturday... 12 laps in and having a serious amount of fun holding off a new 2011 Yammie 450 and another CRF 450 and the shifter just disappeared on me...
Could not find it to get my toe under it... pulled off the track and I can see that it is in the all the way down position.... head back to the pits in what I assume is third gear... I'm assuming that the bolt has sheared that holds it on and I have sheared the splines or something...
This did not happen while shifting.... I was approaching a step down table and shifted into third to get more speed for it and then when I landed, I had no shifter....
Back at the pits I lay the bike over and find that the shifter shaft is just rotating freeely up and down with the shifter....shaft must be broken inside...
Any thoughts guys on what I should start checking for and can I pull the shifter shaft by pulling off the right side case cover.... have spoken breifly with George and Robertaccio... may not have to split the case (crossing fingers now) but anyone else have this happen?
Anyone walk me through this?
