2008 Honda CBR125R fuel injected 1900kms on odometer.bought pre-owned 2 weeks ago very good condition. Past weekend performed oil-change with Castrol motorcycle specific 10W-40 motor oil and adjusted clutch at lever to allow slightly more freeplay. Since when engaging starter it emits a "squeal" like noise just as engine catches and starts. This sounds peculiar? Did not exhibit this symptom when I bought Bike. Might this be an indication of a problem?
thank you.

So your original engine was fuel injected. You bought a used engine that had a carburetor. You swapped the head and cards for your original injected head?
I don't think that is going to work. A fuel injected engine relies on sensors in the lower and upper part of the engine to supply information to the injection computer for what to do next. The most critical one is the crankshaft position sensor which tells the computer where the piston is.
It's not necessary to stay with the Castrol brand for the life of the car, although, some technicians say that it's good to stay with the same brand to reduce sludge.
Just make sure the viscosity is right for the weather conditions when you have the oil and filter changed (and lube).
I have my oil changed at Walmart or Sears and I just ask for their Supertech or featured oil, and my Cadillacs seem to run fine on that oil.
I do not have a clue about this cycle being an oil burner. It may use more oil than usual if you drive it hard, but any engine will. Part of your daily , or at least once a week , pre-trip inspection should be to check the oil. Your concern should be replaced by diligence. One should never ride a motorcycle with out routine inspection for your own safety, and for that of others. Your attention to detail will soon make you the local expert on the cycle and the partial quart left over from the previous oil change will probably never get used.
I think you might be finding out this weekend how much damage you did. If it still runs I don't think you did any damage to it, just got terrible performance. And maybe a little hammering of the valve stems....I was supposed to do my valves years ago, or about 12,000 miles ago, haven't done it yet. Still runs good, when it starts missing and skipping, I'll do it, but till then........ Hope this helps.
