Hey, I can't start the bike. I use it every day and I noticed it was taking little longer to start it for the last couple of weeks. I had to straighten (with a hammer) a crooked part of the front leg shield frame (while it was attached to the bike), it got significantly harder to start afterwards until it finally decided not to start at all the next day (at the beginning of this week). So I did some tests:
1. Battery - I've got the Battery Tender today. When charged it's 12.9V and while cranking it immediately drops to 10.7 and even little below.
2. Starter - I don't remember anymore how fast should it crank, so hard to say if it's slow, but it slows down a lot after maybe 2 seconds.
3. Spark plug clean and working well.
4. Compression - very bad, now 50 PSI (even with the secondary throttle valve wide open), couple of weeks before wasn't much better.
a.) I squirted a bit of oil into the cylinder, no change.
b.) No sign of bad exhaust/smoke, no leaks from the engine, no oil consumption.
c.) No sign of power loss. Before it broke down, so a couple of days ago (it was already cranking long) it was powerful and fast.
d.) Finally I decided to adjust the valves, but it turned out they didn't need it (IN: 0.006 EX: 0.009), they seem to be in a good condition.
And here I got puzzled, a lot of power, good valves etc, but 50 PSI? So what is going on?
