Hi I am a new member. Hoping for some advice please. My GS650E, 1981, is a bit hard to start sometimes, and when idling it gives a click sound and stops. It will usually start again quite easily. It also hesitates briefly when pulling away from a stand still. The carbs were cleaned out 20,000 ks ago and the bike has not been left standing for a long period. I have cleaned out the fuel filters. The plugs have done 20,000 ks and I think the plug leads may be original. Any advice please?
Sounds like it's running too lean or the idle speed is set too low.......or both.
Does this happen more when the engine is COLD ??
Does it have a stock air filter in place ?
If yes, check the air pathways for leaks going into the carb.
Vacuum leaks can occur in hoses going to places like an automatic petcock too.
A dose of a good carb cleaner in the gas every 5K miles/KM is a requirement, I think.
A healthy dose now might help.
I prefer Gumout or Berryman's B12 Chemtool.
First of all let me thank you again for your reply.
I followed your advice, and methodically checked the various items, and although the problem was not any of them, your reply definitely set me on the right track. I had cleaned the filter in the airbox and had left too much oil in the filter, thus restricting the air flow at idle. When I took the filter out it looked very wet, and I squeezed a lot of oil out of it. I kept doing this until i could squeeze no more oil out but it was still dampish, and now it idles beautifully once again at about 1100 RPM. Thank you. Good answer. Good result. Oh yes, I have bought a proprietary brand Carburetor cleaner too, and added it to the fuel. I phoned the company concerned, ( Wynns, ) and they assured me that the product was safe to use in this model bike and that it was impossible to "overdose 'the engine so i did it. All good.
Hmmmm. OK but if you put the WHOLE CAN into ~ 3 gallons of gas, that IS an overdose and while it might not really hurt anything, it is highly likely that it won't run exactly right with that much in it........especially at high rev's.
