Posted April 14, 200915 yr Does the 400 use the same gas cap as the 650? Found a nice gas cap off of a 78 650 on E-pay and it looks identical to mine.

I was able to use a 650 on my XS500 and it fit just fine. Give it a go and if it doesn't fit I am sure you can get your money back for it.
April 14, 200915 yr I just measured three XS gas caps. The 360 and 400 measure the same. A 1978 XS650 Special cap measures 8mm longer.
April 15, 200915 yr From what I know, the standard model 650 from '76 to '79 used a cap that should be the same as on a 400 (or at least was on mine). But the 'Special' model 650 from 78-84 used a different size. (8 mm bigger i guess, by XSwheels measurement). So just knowing it's a cap from a '78 xs650 isn't enough to know if it'll fit. Standard 650 or special 650? They look the same in pictures, so if it's not stated in the ad, you may need to contact the seller and ask.
April 16, 200915 yr Moderator RD caps are the same but the RD400F daytona has the longer cap, if anyone in the uk wants a pattern longer cap i have a nice new one bought by mistake merv
April 24, 200915 yr Author How long is each cap? I don't know whether my bitsa bike is a Special or a regular 400...
May 9, 200915 yr Author Wound up getting a cap off of an SR500 and it fits like it was made for the bike.
