1988 XR 250r smoking and
The compression is low. This indicates bad piston rings. The cylinder may look okay but chances are the cylinder wall has low spots. I suggest you have the shop bore the cylinder and install a first oversize piston and rings. Since the head is already off, I would re-seat the valves and install new valve guide seals. With proper compression the bike will be noticeably stronger.
Need help timing 1987 honda
Backfiring through the carb isn't a timing issue unless you're firing at BDC (180 degrees out).
or have bad/missing/cracked piston rings / hole in the piston.

Bike has no spark 1978
This can be one of five things,
1: The coil is bad
2: The cdi is bad
3: The stator
4: The stator pickup
5: Bad plug
Use a spark plug tester on the coil to test for current, if it doesn't have current to the plug work your way backwards toward the stator, testing each item for current in and out.

I got blue smoke coming out of my tail pipe on 200
This is engine oil burning ,I bet it smells oily.
The valve guide seals under the rocker cover are worn ,or the piston rings are worn and poss the bore on such a old bike this is common.
If you have little money just keep going ,the spark plug will eventually fail,
Or you will need to restore your engine with a strip and rebuild.New seals, rings and check bore piston tolerance .

Need to know how to set timing on 1989 xr 250 r motor cycle
The ignition timing on your bike is CDI based and cannot be changed. Absolutely no way to change it. Valve timing is a different matter and involves static timing marks on the OHC gear. If the bike runs at all then the valve timing is set properly as is.
Pleas rate this solution. Thanks!
