    Hey all, got my bike running, re-opened the head and fixed my stupid mistake on the cams.

    I now have a noise that occurs when I engine break it seems, does not happen when I hold the clutch in and apply breaks, which leads me to believe it isn't my chain tension or chain.

    Its a fairly higher pitched whining noise. Bike runs fine otherwise, no issues that I can see anywhere else. Any thought?

    Most recent changes aside from re-assembly is new battery, fuel, spark plug, coolant and oil change.

    On a side note, my high beams are also stuck on, not as serious of a problem for me but if anyone knows why that would occur I'm all ears to fix it

    Can't help with the engine noise, sorry. On the stuck Hi-beam, might have somewhere too look. On my bike the handle bar switches eventually filled with dust and pretty much stopped working. I took the switch housings apart, didn't disassemble the switches but carefully sprayed the switches trying to get contact cleaner inside. I then wrapped the switches with a layer of electrical tape to seal them and then reassembled the housings. No problems for a few years now.
