Will stock Banshee fuel cap fit IMS tank?

[Rapture]

I have a IMS over sized tank which came on the bike when i bought it and i want to get a billet cap for it.  Does the stock cap/tank use the same thread size/pitch as IMS?

I believe they use Honda caps

My stock cap fit on my 4 gallon ims

I emailed IMS and they said only their caps will fit their tanks. I found a nice billet Tusk one from justgastanks in the end.

I just took my stock gas cap off one of my shees and placed it on my bike that has an IMS tank and it screws on and appears to have the same type of thread. Now it does have fewer threads and only screws on maybe 2 turns till seated but it does fit.
