How to Clean your Decompression Port on the Moster 185 with Vittorazi

If your Moster is getting harder to pull-start, and it seems to be harder to crank it over, then have a look at the decompression port, inside your cylinder. This little hole, that goes from the combustion chamber to the exhaust port, is getting clogged every 30-50 hours, with carbon residues, so getting it clean will make your engine to be as easy to start as when it was new. Although not a complicated operation, it requires a few tools and some mechanical skills. Nothing that you can’t do at home with the engine installed on the frame though.
