Finally durable-looking aftermarket oil tank

[Snowmobileaddict]

I am not affiliated with the seller or the builder of this tank I was just pretty happy to stumble across this tank that a builder in Michigan is putting out for those that are fed up with the oil tank that Yamaha has been offering on the RX, Apex, and Vector machines.

I had my tank crack and develop a leak last season, but luckily I was able to find a like-new take-off tank for $30 shipped. Before finding a cheap factory tank I had been asking around if MPI sells their oil tank that they ship with their supercharger kits as a standalone upgrade, but none of their vendors would reply to me.

Anyways, I know that we are not allowed to post links to eBay. As such if you want to see what I am talking about, use the following eBay search keywords:

apex cfm oil tank

Looks pretty beefy to me. Even though I have sound tank now, I may pop for one of these before the year is out just because it seems most of factory tanks will crack with aggressive riding.

Nice looking tank.; Expensive thought $210.

Thats what I thought too intitally.

However a new replacement oil tank from yamaha is north $250 USD.

I think this would really sell well at like $149

Cfm performance has a lifetime warrante on all thier tanks against cracks or breakage.
For me. That alone is enough of a reason to purchase this tank over the stock tank when your tank cracks

I had enough of cracking stock oil tanks, I think my boosted Apex is especially prone due to running solid motor mounts.
Pulled the trigger on one of these CFM Tanks, wow real nice piece!
Although in the pic's it looks smaller, it's the same size as the stock stamped tank.
All the fitting locations and positions were spot on, no issues lining any lines up, dropped right in.

The only criticism I would have is the rubber gasket for the steel bottom Oil Strainer / Screen pickup squeezes out and doesn't seal real well, weeped oil no matter how light I torqued it down. I ended up putting YamaBond 6B on it and problem solved. I would suggest that they simply revise the outlet flange and maybe machine in O-ring groove so you can simply use the original OEM O-ring.

Haven't had much snow here in WNY this season, again for a 2nd year, to get any hours and thermal cycles on this yet to provide a durability comparison, but just looking at it you can tell that is the last tank I will have to buy for an Apex. I would recommend one.

300 miles so far on mine. Works great no leaks no worries. The old girl is like brand new now with all the other work I did.

True, it's a great tank except it always weeped. I made different gaskets from different materials, with no luck. I sealed it all with pc7 since the hose can come off easily. I suspect the threaded rod is actually threaded through into the tank and the seepage is along the threads. I indicated the gasket surface and filed it flat...to no avail. They should have just machined the o ring groove.
