Oil tank leaking

[micaelaman]

Hi,
It has happened to me as well. The oil tank has cracked. It is a common problem, but there are surprisingly few picture of it. So here goes.

Here with JB-weld.

My plan is to buy an new after market one. But for now i will give JB-weld a try.

I have done that with some on the rs nytro I had. Them ones were separated at the seem though. Jb weld don't last long, u will get a few rides out of it though, long enough to get another one.

Thanks for the info. I have ordered a new tank from CFM. Hope it will turn up in a near future.
Even if it will hold up, it will be in the back of my head when riding. I'm not a fan of these magical epoxies, even if JB-WELD is one of the best.

The JB weld will probably hold forever to be honest, that stuff is amazing, lol.

I broke 2 oil tanks last season, both of them split on the seam.

I used it on a car oil pan once and on a gas tank. It held for years on both occasions

does the cracking come from getting hit by something or just poor design?

Poor design In my opinion. I've cracked a few of them then put some rubber washers on the last one between the tank and the chassis it bolts to, lasted 3 times longer right up until I sold the sled. Now I see Yamaha sells a oil tank saver kit, I have not really checked them out but looked in pictures like a more professional version of what I did. Aftermarket places also sell fabricated ones instead of the 2 halves like oem.

I don't know if the previous owner has hit something. It started leaking last winter and gotten worse when a change oil and o-ring. I think the crack got bigger when i removed the bottom hose and had to wiggle it to get it lose. The aluminium is very thin so it's not suprising that it has cracked.

Yamaha sells an oil tank saver kit?

Seems like I remember seeing it in the accessory catalog. Can't seem to find anything on it though. Looks like u sell a kit for it also.

I'm sure that kit is fine, pretty good reputation with anyone u have dealt with here on ty

I have ordered a CFM after market tank. It hasn't arrived yet, but it is transit.

I have had one ride with JB-welded tank (100 km) and so far no leaks.
