tank swap question

[gussy]

Does anyone know if the 97 yzf 750 tank is the same as the 600r thundercat tank and would the r6 99-02 gas cap fit this tank ?
I found one for cheep.

The '95-96 YZF600RG/RH use the same tank as the YZF750. The '97+ YZF600 uses a somewhat different tank, with an external fuel pump. I can't comment as to the mounts and outlines, etc.

As for the cap, a quick check of EvilBay shows a selection of aftermarket keyless caps that claim to fit all years of R6, and the early YZF600 (= YZF750 tank). Check it for yourself, but I'd say it looks promising.

I can confirm that the mounts between the Foxeye (600 & 750) are the same as the Thundercat (600).

But I would recommend against using it. Only reason is that the internal fuel pump is a PIA. It is difficult to source one that is in good working order if it ever goes out. There is no petcock switch so it takes a little bit for the gas to stop flowing if you ever have to take the tank off. It also uses the vacum lead from cylinder 1 into the petcock which is just another line to connect and disconnect when servicing is done. Beyond that, I like that tank a lot more than the Thundercat tank. The internal fuel pump has an advantage in that it removes the external pump from the mass of crap under the tank.
