My 800 R '09 Summit broke down on 1/22/11. David brought it in to Houghton Motor Sports on 1/24/11. They told him my 4 year warrenty did not get registered!! David proceeded to call Marty P. whom used to run Keweenaw Motor Sports, he jumped in and took care of things and we have warrenty. Thank you very much Marty your the man! It ended up I needed a new short block, head, piston, everything! Only a $50 deductable and everything was covered. Tim from H.M.S. called me 3 times with updates, and I picked it up on Saturday 1/29/11. Very good service,very professional. Want to thank you Tod and everyone at H.M.S. I guess I can continue to ride Skidoo!! Lori
