I have been facing problem of engine heat up in my 1993 gs500e. The bike runs good when it is initially started in the morning but heats up as soon as it hits a little traffic. The first gear requires high revs or else bike won't move. Also the clutch seems to become harder. At this stage bike doesn't idle and needs a bit of throttle. One more thing, the red oil warning light lights up at around 1200rpm but as soon as I give it a little throttle the light disappears. The following is the list of items which I have looked at but still unsuccessful in finding the source of the issue:
- fuel pump checked
- changed oil and oil filter
- serviced carbs
- checked bearings and they are fine too
Temperatures reach about 120 (now a days in summer) where I live but my fellow gs500e riders still do not face engine heat up issue with their rides. Someone told me that hard clutch maybe due to worn out plates. I recently replaced clutch plates but the problem remains. Clutch still gets hard after the bike is in moderate traffic and gears get harder to change.
P.s. I have had this problem since the winter when temperature was around 60.
We do not have a fuel pump. Not sure how you could check that.
Serviced carbs how?
Checked what bearings and how?
Try the standard 3 point clutch adjustment as in the WIKI.
What oil are you using? Are you watching that you don't get low on oil?
What is your idle set to?
What RPM do you normally ride at?
Was anything done to the bike (or happen to it) around the time you started having problems?
Does the oil light come on? (It should be on until the bike started. If not, check the bulb).
It could be a bearing going out somewhere. Could be wrong type of oil.
Thanks for your reply adidasguy. I am talking about this http://www.ebay.com/itm/Suzuki-GS500-Oil-Pump-GS500E-1989-96-/160440907033?pt=Motorcycles_Parts_Accessories&hash=item255b05f519&vxp=mtr . Sorry I meant to write oil pump. I opened the carbs and used a can cleaner like this one http://www.ebay.com/itm/Carburetor-Cleaner-13-oz-Aerosol-GM-12302498-/221238184133?pt=Motors_Car_Truck_Parts_Accessories&hash=item3382d2c8c5&vxp=mtr .I have done the clutch adjustment, the problem is that clutch gets hard only when bike gets stuck in traffic and I need to use it more. I am using 20w-50 oil and changing after 2500kms. The red oil light turns on when I turn on the ignition switch and then turns off once the bike starts. The light keeps coming back and going after bike is hot. I usually ride at ~110km/h at about 5500 Rpm in 6th gear. My idle is set at 1500 Rpm.
Around 3 months back the bike started reducing engine oil and on inspection I found that rings and piston needed replacement. So I changed them. One more thing, when bike started reducing oil, i noticed that the oil in the engine smelled really bad like it was burning. After I had replaced the rings and pistons this problem went away. But I never got to know the reason behind severe burning smell of engine oil from the engine. The bike was fine after rings and pistons replacement but now it has started this weird problem. I am now thinking that the valves may need replacement too. But I am not sure.
What are your views adidasguy?
