    Yea I switched to the small ones after the big ones got ripped off trail riding, they're nice. I think I'm gonna go with the Clarke 5 gallon. Thanks for your input

    Just one thing; it has a single throttle cable setup which I haven't seen on an XR before....and the usual jerky on/off throttle delivery off of idle..

    I have got a 1987 xr600, the threads in the cylinder are thrashed. There is a 1992 cylinder for sale in town, Will the dual carb head fit the newer cylinder? They look identical on the pictures but are the studs the same size etc? Thanks!

    Should do, but why don't you helicoil your existing head?

    The threads are m9x 1.25mm.

    No idea there but with a heli coil, there isn't a need to upgrade to a larger size. The area of thread the steel insert is griping on the aluminum is larger when you use a heli coil. It is like using a larger bolt without having to enlarge the rest of the holes in the system. Also, you won't have the steel bolts running against aluminum if you have a heli coil. When you tighten the bolt, it will now be steel on steel.

    Oops, my mistake, 8mm it is. But the same applies, you will just have to find out if it is m8x 1.0mm or m8 x 1.25mm thread, as the Honda
    parts fich does not say if the pitch is 1.0 or 1.25.

    If you were to use a later model cylinder, you will have to see if the bolt holes line up, and get the m9 bolts to suit.
    The cylinder to casing bolts are the same between the 87 and '92.

    The 1987 XR600 uses a 8mm head to cylinder bolt. The 1988 and up XR600 use a 9mm bolt.

    The bolt pattern is all the same for all year XR600.

    The '87 has 9mm locating dowels where the 1988 has 10mm dowels.

    Yes the 1992 cylinder will work but the dowel holes will need to be enlarged to the 10mm diameter.

    A good machinist should be able to install a 8mm beli-coil in your cylinder. I would have all four done if it was me. Better yet install the 9mm heli-coils in your cylinder. The larger 9mm bolts don't break like the 8mm bolts do some time. Only issue is a set of 9mm bolts and washers is kinda expensive.

    Thanks for your input! The 87 cylinder is already helicoiled and my mechanic thinks its a weak link,
    since the engine is rebuilt from scratch it makes sense to look for another cylinder.
