Motorcycle Headaches

I've been bugged this week by the constant breakdowns of my motorcycle, within just few days of interval, I already incurred a lot of expenses.  My bike will almost be 8 years now, that maybe the cause.  Just a few days ago, I had it checked  by a mechanic friend since I noticed it had a slight swing to the side which I find it hard in driving especially when the road's muddy in my place of work. He found out that the problem was in my bike's swing arm and replaced the damaged parts.  Just 4 small bearings and their collars, already cost me 3 thousand plus.  And more, though I'm using it for company use, I can't already have it reimbursed since I already exhausted my allowance from previous repairs and maintenance. 

This is the XR200 motorcycle piston.  It should be smooth and scratch free.
And the inserted photo was my previous, see any difference? LOL.

And just today, as I was going to work, it started to have a knocking sound in it's motor part as if it's about to lose compression.  So I decided to go back to have it checked and drove as slowly as possible as not to aggregate the damage, if there was any.  As I arrived at the machine shop, my mechanic friend told me, it was due for re-bore since the piston had already accumulated several scratch marks and my camshaft needs to be replaced.  Whew, all in all, that's almost 10 thousand pesos going out my pocket...

Normally, a good camshaft has a smooth and solid surface, unless it's brand new.

I really, badly need a new bike, right now.  I guess, my motorcycle, considering its age, is no longer fit to endure tough terrains.  Well, still my fault, I should have asked for it 4 years ago, when the standard unit was still XR200, unlike now.  I was just thinking before, that I would help the company not to get one since my bike was still in good condition.  "Haaay", now I'm no longer sure if I did the right thing.  I should have thought that I won't get any help from anyone for that matter, aside from the standard repair and maintenance allowance given to us... any expense beyond the company's budget will be shouldered by me, which i find really costly since my motorcycle's major parts being damaged by wear and tear are not cheap.   I guess what I can do right now is wait for the standard unit to change back to a sports type unit which I believe is fit for the rugged and rough roads of my work place.  Not because I'm choosy, but I'm considering safety above all.  Yahweh bless.
