Good morning everyone.
1. It seems that I need a long time to warm up my bike in the morning, have to keep the choke on for about five minutes. Then the bike's RPM reaches from 1500 to almost 3000 in idle at all of sudden. I have to turn off the choke, because I think the RPM is too high for its idle. But the engine will be off as soon as I turn off the choke. So I have to hold my throttle a little bit and keep the RPM under 2000 for another a couple of minutes, otherwise it will die at traffic lights if I ride it.
2. After coming back from the rally last year, I replaced fuel filter, a damper and two fuel hoses from tank to the rail. But the bike uses much more gas than before. I remembered that I could ride almost two hundred mile with a full tank. But now, less than 150 miles I have to fill it up.
I replaced spark plugs, ignition wires, thermostat about 30.000 miles ago. Replacing air filter every 20.000 miles and changing motor oil every 3000 miles. I always use BMW original parts and I really don't know what causes the problems.
The bike is only 47.000 miles on it. Is it suppose to be like that because of the bike's age?
Anyone has some ideas what's going on here?
Thanks in advance.
