4th Gear rattle 03 Dynna fXD
Just noticed a nasty rattle in 4th gear, no other gears.I always ride with ear plugs and never heard it before but just rebuilt my forks and took it out for a test ride without the earplugs and was shocked at the rattle. Was just going through the neighborhood not fast and when in 4th especially off the gas it really sound nasty. Checked the primary belt, tranny oil for proper fill and even drained some out to look at the magnet on the plug. didn't see anything wrong there. I don't know crap about the tranny so any ideas?

Don`t take post #2 seriously, he is just having fun with you.
Disconnect the shifter rod from the shift lever at the transmission.
Move the shift lever back and forth, does it spring back to its centered position?
Do you still hear the noise if you pull the clutch in while riding in 4th gear?
Do you hear any unusual noise when idling in neutral, clutch lever released?
Check exhaust to make sure the pipes aren`t rattling.
You need to make sure the noise is not coming from somewhere else before you start opening up the transmission.

Been thinking about why 4th gear. When passing I have had a habit of banging into 4th from 5th and nailing it hard. I always used the clutch but that has to be what caused it, been doing it for years, just like that feeling. Won't do it any more though.
