Just bought a 2002 gs1150 non abs a week and a half ago with 5000miles. I noticed that it had recieved its 600 mile service but non since. So I changed the engine oil, gearbox oil, final drive oil, checked the air filter, did the valves and changed the front and rear brake fluid. (nice easy bike to work on compared to my GSXR600 and MZ Scorpion!) However, there now appears to be a weep at the reservior cover above the front master cylinder. I cleaned and dried the cover before refitting it and the rubber seal. The reservior was filled according to the spec in the manual. I've cleaned and refitted the cover a few times but still a weep. There are no obvious defects with the seal. Any Ideas to cure this? Thanks.
