The Benelli has been a part of the collection for nearly 3 years. It is a beautiful bike and the six separate pipes sound very special. However, it has given us many of the typical challenges classic & Italian bikes can give. So nearly all the rubber components and much of the electrics (coils, plug leads, fuse box, kill switch, ignition switch etc) have been replaced. Carburettors have been redone & about a year ago we converted from points to electronic ignition. Despite this the bike developed a very bad habit - after some 10 miles riding it would lose a cylinder & start backfiring and spluttering. It did this on every outing. We assumed this was fueling related and suspected that rust from the tank was being liberated and was fouling one of the carburettors. So we did a thorough tank lining (acid treatment and then a Frost lining product). This also led to a repaint given that the acid caused some damage to the existing paint (new paint done in the correct pearl white). Great result from the tank viewpoint but still kept losing a cylinder after 10 miles. Dave & I had the bike on a ramp and were testing it in the shop - trying to see if we could emulate the conditions after 10 miles riding. We had the points cover off and noticed that once the bike was hot one of the three LEDs (one light per pair of cylinders) on the ignition plate started to flicker and then went out. It transpired that there was a fault in the almost new ignition. So this was replaced. And lo and behold we now have a perfect running machine (at long last) that also looks really good.
