Hi, Jim your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on startup is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on startup may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on startup is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

Hi, Robert parts swapping is common with most motorcycles when it comes to interchangeable or compatible parts from one model with another "EXCEPT" for the CDI's they are year-make-model "SPECIFIC" the best thing to do is call your local Dealership Parts Department or a reputable independent shop. If your location is not near a shop then go online and find a parts catalog or "FICHE" and match part numbers depending on your criteria.

Take a look at the exhaust valves. If the exhaust valves are not opening, the pressure will build (sort of like an air compressor). There should be a cam for the intake and the exhaust, make sure the cam and the valves are operating correctly. Also, check your base gasket and head gaskets. If either gasket is too small, it'll boost your cylinder pressure. It is common to switch out the base gasket and/or head gaskets with thinner ones as an inexpensive mod to boost cylinder pressure. Lastly, too much carbon on the piston head or cylinder head can boost cylinder pressures (rare); the carbon can be a problem which can lead to detonation as well.
