I'll start by saying I am a newbie to trials,I didn't get to tinker with the bike at all. Just trying to see if there's a generic issue or problem before I start any teardown. Sometimes a headlight on my bike is bright sometimes not but it seems to always have a illumination..... The brightness does not change with RPM. Didn't know if there was a specific regulator that goes bad or some other issue.... Just reaching out let me know what you guys think? Also, I first bought the bike about a month ago, and I've smelt coolant every once in a while....? Thanks for any help in advance...if somebody is aware of any of these issues and they know what part number has fixed it....ie water pump seal,...headlight regulator part number. I would Love to know those part numbers thank you
