Well i just got this 85 yamaha ovation and someone modded the crap outa it! It has a whole new suspension front and back. A newer steering post and new bars and brand new skis and carbides. I cant figure out with kind of skid its got in it but its deffently not a Yamaha one. But the motor is a rupp 440 and was not mounted correctly and such. Honestly it looks like some guy put alot of work into the body and suspension but must of ran out of money when he put the motor in. Then got to thinking about making my own custom sled. So i have made the design on what and how i want to do it. I know that i will be using the 1985 ovation 340. And that i want to use a Polaris triple in it but i need to find a engine first. I have a whole shop full of metal, bolts, tools ect.. I have had this idea in my head for about a year now and i have finely decided to do it! I have been scraping to make some play money and i am looking to buy a good running trip for about 350$ Let me know if anyone has a motor they want to sell me.
