These are the gaskets that came with your big bore kit.
There is a catalog section and you just need to measurements
of your bore size. I have the 240 kit as well best 500 bucks I have ever spent. As long as the gasket came off clean and there are no rips you should be ok, but the kits run for under 50 bucks so better safe then walking. :ride:
As long as it's not creased/bent, it should be good...but you will need to use a gasket sealer made for that purpose...like Permatex copper coat.
Some paints work..like Krylon aluminum.
That said, the last gasket I used I REused..and I do have a bit of seepage visable at the head joint. By 'a bit' I mean I can see it..and that is after 200 miles of riding over a weekend in a lot of dust.
I've never noticed a new gasket doing that.
Walk thru the pits at a drag race. Some guys rebuild engines after EVERY run..and THEY reuse head gaskets.
Yeah yeah...not altogether the same thing..but a bit the same. Kind'a like my leak..a bit! ;)
Last year I tried to find gaskets for my KDX240 in Australia, but was unsuccessful. In the end I obtained some from Kustom Kraft over there in the USA - try them.
