Question about 2005 Gilera 50 SMT
Hey..did you get the stock exhaust with the bike...if not..go back and try to get it,,Sounds like the carb may be in need of a professional cleaning.. and with the aftermarket exhaust.. it might be time for some jetting...(A QUALIFIED PROFESSIONAL ONLY) can do this.. NOW - A "power band" is simply the RPM range that the engine makes the most power... it is nothing special.. Road race bikes have a high PRM "power band" and a trials bike has a low RPM"power band"..AND some bikes do not have a power band because they are ridden by the "masses" and they can't handle "power" of any kind..

to check the electric choke..take it/off out of carb & unplug it. then get 2 short lenghts of wires, strip both ends...shove one end into the choke plug teminals(one in each hole) .then put one of the striped ends of thewires on a charged battery(one on the positve & one on the negitvie terminals) .keep them on for about 5 mins & you should see the choke head extend (you could always mesure it befor you put to battery & check in 5mis to see if extened!!) this will tell you if its working!!...if its not working this will explane why you have trouble starting from cold!!..it also sounds like the main jet is blocked...this is found by taking of the float bowl (as you may know!)it will prob be the small hole up the middle of the jet that is made up with muck!!...try sticking a strand of a wire brush up/threw it...also it sounds like the exhaust is leaking round the maifold..will have to take exhaust of & check if it need a new gasket..or resealing!!(does the exhaust blow?. this is good way to tell if it is leaking(put a rag/palm of hand over end of exhaust & you should beable to hear it blowing. ...hope this helps....Howard

It could be a blocked carb but it sounds more like a spark problem. I am assuming that you have the right gap on the plug. If you do it could be either the exciter on the magneto or the cdi unit. The bang is nothing more that unburned fuel exploding from a spark so you know that you have fuel and spark. The trick is now to get them doing what they have to at the right time. I would start with the cdi unit. They are quite expensive so take yours out and ask the dealer to try it out on another scooter before you buy one. They are a small bkack rectangular box with a connector with usually 4 wires going into it and you will find it either under the seat or in the battery box. If it is the exciter, let the dealer sort it out as it is a fiddly job.
