Hard kickstart this morning.

[DaLoCo]

I have a bike with a 200cc 169FML engine.

This morning my battery was dead, so I had to kickstart the little beast. I found that it was extremely hard to get it to turn over, almost as if there is way too much compression. After charging the battery it started easily, but now I understand why it sometimes kicks the started clutch out.

So, could it be valve lash? Intake is .005 and exhaust is .008. Is the exhaust too much? I have noticed a lack of real performance. A while ago we had a seriously hot day, and the bike came alive with plenty of power, so I am thinking that it could be that the hotter engine had something to do with it, hence my leaning towards bad valve clearances.

I am also considering the fact that the timing chain could be stretched, or has even jumped a tooth as the idling isn't the smoothest.

The bike has done more than 50 000 kilometres on this engine, so it is a real stalwart.(not going to mention the peripheral parts that are not quite as durable.)

Valve lash wouldn't be the cause. Maybe carbon build up in the combustion chamber? If it has a timing chain it may have an automatic compression release on the cam that wasn't engaged.

Did you try to push start the bike?
