Well, I have been systematically renovating my 2001 Beo 150 which I bought new and now has 20,000 miles on it.
I replaced a lot of the parts that had just plain worn out like my rear shock and the rubber motor mount blocks and hard plastic covers, the bushing the engine connecting rod pivits on I replaced, some of the fuel lines, both brake rotors & pads with a fluid flush, some new bodywork that the headlight mounts on, cleaned the brake switches because one wasn't working, reupholstered the seat using Sargeant Seats, adjusted the valves, new pirelli tires, all new variator rollers, clutch pins, variator belt, changed the engine oil, filter, and transmission oil, cleaned the air filter, replaced the spark plug, installed new starter solenoid.
And just for kicks I installed a new side stand kit.
The bike runs great now and my new suspension system makes a huge difference, because my old rubber motor mount blocks were breaking apart and my old shock was really bad. The installation of the motor mounts was quite challenging the rest of the work wasn't too bad.
There are just a couple of things I still want to address:
1st is the airbox:
I got a good look into the old style airbox when doing the shock absorber installation. The part of the airbox that the fresh air first flows into is caked in oily grime. I'd like to disassemble the airbox and clean out the inside with something like Gunk engine cleaner or replace the whole airbox with a newer one. Also the 2 plastic tabs at the bottom of the airbox for drainage and the breather connection on my bike broke off a long time ago so I plugged them and just put a seperate little filter on the end of the breather hose. Has anyone ever disassembled their Beo 150 airbox? If so do the 2 halves screw together or are they glued together.
Someone is selling an '03 beo 150 airbox (new style) on ebay. Does anyone know if the new style airbox with different type of air intake like a snorkel or something would bolt into the 2001 model. I think then i'd have to also change the under the seat cover that hold the tool kit and the seat latch to the newer version, also for sale on ebay.
2nd the coolant:
My coolant looks fine, but is at least 4 years old. The maintenance manual says to drain it from the drain plug and bleed it from the top of the thermostat in order to change the coolant. I'm concerned of future leaks or breaking the somewhat fragile looking thermostat doing this since I'm not sure how frozen up these drain and bleed screws are. is it better to change the coolant by just disconnecting a hose to the radiator?
Thats it, once i get the airbox and the coolant restored then I'll just need to change my throttle grip and throttle cables and I'll feel like my bike is ready for years more service. The throttle works OK, but the cables are original and well worn and the grip itself is worn and taped over. I have replacement throttle cables already and I'll probably buy new grips as well, just got to get around to that. New grips would really be the cat's meow. The engine runs very well, burns no oil and pulls strong up to a speedo indicated 80 plus mph. I was a little concerned about the valve adjustment I just performed because the tolerances are so tight but I just did it by the book and engine literally purrs now. I'm excited to get this bike back on the road it has given me a lot of joy over the past 11 years and I'm hoping to keep it running a lot longer.
So if anyone knows anything about taking the airbox apart to clean it, swapping the new style airbox for the old style, and about changing the coolant please give a holler in this thread.
