I have an aprilia rs125 1993 model,i originaly thought that the bike wasnt finding gears apart from 1st n 2nd but have been told that it is the gear lever not returning to position after each gear change that is causing the problem.I have only been riding a few months and this is my 1st bike so i am at a loss as to what part i am looking to replace??? i would be grateful for any advice. Thanks. clair

Hi .... Try switching the petrol off just prior to stopping the engine and start up again with the petrol OFF. There's enough petrol in the carb to start the bike. A good battery should show over 12 volts. Take the plugs out and give them a good clean or replace them. Is there a petrul pump fitted ? A two stroke needs to be ridden quite hard to maintain efficeincy, higher revs etc ........ let us know how you get on ?

It sounds like something is preventing the bike from getting fuel. Check fuel filter, fuel tank vent, air filter too. If you have vacuum building up in the tank, letting the bike sit for a few minutes slowly releases that vacuum allowing the pump to pull fuel easily again for a bit. Next time the bike quits open your fuel tank. If you hear a whoosh of air being sucked in look for a plugged vent line. A plugged air filter can have a similar effect but the only way to check that is change the air filter or look at the one you have. It would have to be really, really dirty or plugged with some debris to cause this problem.

Nope. Pressure plates use mechanical springs which don't fail with this symptom. It's your pressure cylinders for the clutch fluid. Either the main cylinder that is activated when you squeeze the lever or the slave cylinder that moves when fluid is displaced from the main cylinder. Check the fluid level in the small tank usually located on the handle bar and connected to the lever housing. No fluid = source of problem. Refill with the proper fluid. However, if the fluid has gotten very low, you may have gotten air into the fluid line and will need to "bleed" the system to restore good lever pressure and clutch function. Buy a repair manual...Chilton, Clymer, etc.. for your bike for details.
