Thanks for sharing your story. Now lets get back on track here.
Barn of Parts/Travis get get that bulk head issue fixed up. I have the Bulk Head Saver kit on my sled. Very easy to install.
TY advertisers like Travis or Laneo as well as the classifieds should have all the other necessary used parts you need. Other advertisers/vendors like Port Yamaha, Pats Motorsports, Dranttel Sales and Service can supply new parts if you need.
Take your time wrenching the sled back together. I've wrenched with a cast from elbow to finger tips. Not a lot of fun.
Best of luck.
