Before we get to the parts, it is still under 1000 miles old, so its very much in the “running in” stages

Around 600 miles , it is mandated for dealers to;
– check valve clearances (must be checked otherwise tight valves or loose ones will have a domino effect on peformance to the engine, carbs, etc..)

– Compression Test (very easy) – must be sure the pistons are putting out correct PSI after it has warmed up,
— Warm up engine -> then remove plugs (both of them) –> crank bike for 5 seconds max –> read compression.
Repeat again for rear cylinder too

Let us know the PSi it is doing
