Hello there,
I've spent countless hours trying to fix my TRX 450. I was almost sure my problem was due to either starter clutch or starter gear based on all the researches, the sound and the quad starter behavior. However, after opening up the case and double checking the issue, my starter clutch/gear seems to be operational. I've noticed you reside in Vancouver, WA and that's where I live as well. With all this in mind, I was wondering if we can get together at my place and maybe I you can share your abundant knowledge about this things, because I'm definitely not a PRO. I appreciate your reply. IB
