Bad Starter And Lumpy Slow Running

[leemo]

Been here a while, so time to get involved.

Got a 1996 trohy that has been stood awhile. I have been informed that the carb's have bee cleaned but it will not start readily and takes a time to settle to idling. With riding seems to get better but m/g is very bad.
I changed the thermostate as when run on the drive the temp rises until the fan comes on, but when on the road the temp display shows a cold engine but whe stopped temp begins to ride which sayes to me that the air passing through the radiator is coolig the water so the engine. this is not good as a cold engine is not runing at its best....... Any ideas..

So tough to diagnose on a message board with limited information.

Fist off....new fuel is a must. Second, new sparkplugs. Then, since you believe the carbs were off, I would check that the carb intake rubbers are not cracked and are properly installed. It's easy to get one or a few of the rubbers folder over and not perfect at the intake. While you are there, pull each fuel hose at the carb and check the tiny plastic fuel filters there. I would add a bottle of Seafoam to the fuel. Next, crack open the fuel cap and ride it. If it improves, then the fuel tank vent built into the cap assembly is clogged and it's starving for fuel.

A '96 Trophy doesn't have a temperature gauge so I'm not clear on how you're seeing it rise and lower. Be sure coolant overflow tank is to the full mark. It would be normal for it to rise while idling at a stand still until the fan comes on (which proves the temperature sensor is working) and then to cool when moving. But it shouldn't cool it too much - which is a function of the thermostat. Be sure its installed correctly, is the right part, and is working properly.

Ta for the reply.

It has had a few fuel fill's with a drop of carb cleaner, not done the plugs yet. Had the air box off and found the modification had been done and a KN filter fitted. I have changed the fuel pipes ad made sure the filter is in there, and the vent in the tank is clear. I think this is a early 1996 (first registered then) but it has the trident dispay with rev's, speed, and the idiot light's in the middle and the temp guage above them. I did not take the carb's of the engine as I did not want to disturbe the joint.

Each carb has a tiny plastic fuel filter right where the fuel line enters them.
