The can is my oil reservoir.just trying to keep the weight off the front end as much as possible.it worked, it really feels light. the turbo oil tank it came with was a huge flat bottom tank mounted in front of the motor. The flat bottom would cause it to trip the low oil pressure switch when I lean it over to far.The new tank works great. I still have a month left to tweak it and then over the summer it will get an over the motor steering post and a new seat. I am having a blast with it. I'm really thinking of getting a second full body apex to put the turbo on and only ride it when the snow is over the hood. This one needs some more work on the clutch cover, when I drag the left handle bar even in hard snow sometimes it gets snow in the clutch enough to slip.
I'm in full agreement not to spend a lot of money on an old sled so I'm pretty cheap on most upgrades but I did shell out for a Shorai lithium battery. It is so light I just zip tie it to the top off the steering rack. I thought about moving the battery to the back somewhere but the extra wire would have weighed more than the battery. It was The best money I spent on it by far. Well the $20 I spent on the attack 20 was pretty good too, it works great backwards.
