Base Gaskets

[Treesmacker]

I just did the top end on my 300 and used a .3mm (.012") base gasket, same thickness as before. It started on the first kick but, Now I have a small coolant leak on the front side of the jug.
Would gasket sealer (spray type) work to seal this? Both surfaces are clean and free of scratches.
Or go with a .5mm gasket? squish has been set with a .3mm gasket.
Thanks!

I always use a light coat of gasket sealer with any gasket. Make sure that the center case gasket is not protruding and the surface there is flat. A little extra sealer there and at the rear joint won't hurt.

Just pulled the top end off my '09 300R as it came stock with 3 base gaskets in it (0.5, 0.3 and 0.15) and replaced them with just the 0.5mm gasket that came with the spares. My question is has anyone else done this to their 300R, what sort of difference did it make to the power delivery and will it increase the compression too much? I have yet to get the head machined to get the squish band correct but will be doing that when i put a new piston in later down the track.

Cheers,

I could have used just the .5mm, but used the .3mm and .015mm as the parts manual said. Mine came with the .3mm and .5mm. It made a world of difference and really made my bike run way cleaner.
