I recently purchased a 1998 KTM 300exc from a friend who bought it then decided maybe it wasn't the best beginner bike for him lol. I've been out of the dirtbike scene since highschool but this KTM has really gotten to me and I find that I'm spending every waking hour fixing,tuning,massaging,cleaning,riding and re-tuning the old girl,so I decided a top-end rebuild was the next order of business. The other day I noticed that the base gasket looked a little bit thick compared to the one included in my recently purchased moose gasket kit,so I tore into my new love to discover that there were actually 4 base gaskets installed and I got all excited thinking about all the compression I was about to gain by pulling off the 4 and replacing them with my 1 new gasket that I just got...... then something dawned on me. With all 4 on the bike the piston comes right up where it needs to be at TDC,which I assume means that with just 1 gasket it will travel too high in the cylinder,right? What gives? Any opinions and/or advice will be greatly appreciated.
