I'm not sure where you are going with this , but will continue to watch I think I would scrap the old tunnel and build a tubular frame to mount engine and suspension
Thanks for the views. The plan is to build it into a track sled with a sleigh to ride in. I choose to use the old tunnel because it is aluminum and pretty light weight plus it keeps the track/suspension/drive shaft all lined up without trying to refigure out the geometry when building your own frame. Stay tuned for more videos and a test run once its completed!
After watching videos of other track sleds, it seems like having the motor to the front causes it to snowplow and get stuck. I am hoping having the motor closer to the back will let the front be lighter and float over the snow better. We will see when I get a test ride in.
That is a Zongshen 125cc 4 stroke single cylinder engine with automatic clutch, 3 forward speeds and reverse. It is similar to what you would get in a China made ATV. It is rated at about 7.8 horsepower and 6.5 ftlbs of torque.
