so the carbs have been redone, replaced the rubber flanges and airbox rubber boots so its all sealed now and can be synced properly.

for some reason though i still can not start my bike. its run before but simply on starting fluid i put in the spark plug holes

i am in desperate need of getting this fixed so any and all help will be most appreciated
 
Is there fuel in the float bowls? You can check by removing the drain screw in the bottom of the carbs.
 
It starts when primed ?? Go back and check the petcock operation. Might do a compression test too.. Valves adjusted ? New plugs ? Check 12 V on coils.
Start ritual- prime to make sure the carbs are full. FULL CHOKE no throdle
hit the start. Could also jump it from a car battery, some time it needs that little extra bit of juice

idk about valves.. yes new plugs and all work.. tested for spark. tried prime with choke and no throttle. compression is on last time i checked..
dont have jumpers for car but will try when i get some

Hard starting is sign of a needed valve adjustment.
If you jump it from a car DO NOT have the car running.:)

Will try in the morning when i have cables. also will see whats up with the valves

thanks will reply when i have learned more
 
I seriously doubt the problem is the valves...although they NEED to be checked. Most likely the float bowls are not filling with fuel for some reason. As I suggested above, and was ignored, you can check for fuel in the float bowls by removing the screws on the bottom of the bowl. Use a rag under the screw since if there is fuel, it will spill out.

Another thing to try is blowing air into the carb vent tubes, this forces gas up into the carb passages, assuming there is fuel in the float bowls that is, and primes them so to speak. Many times, once fuel gets up into the inner passages of the carbs the bike will start drawing the fuel after that.

Good luck.
 
sry did not mean to ignore that part just so much to do because i am not too experienced but capable of figuring most of it out...

I am going to check the float bowls and if not then try the other thing you suggested.

I will repost when i have the results

Thanks again all :)
 
its nice that he pointed it out though because i had missed that one part
 
What's bad if you have the car running and jump it? Is it to do with the R/R on the bike?

Yes. The car's charging system puts out too much amperage for the r/r on the motorcycle. You will fry your electrics if your car is running when you jump your bike.


Mr. 1982gs650E,

Please re-read the mega-welcome, paying particular attention to the "Top 10 Common Issues" and the carb rebuild series.

There are no shortcuts. Keep us informed.

Thank you for your indulgence,

BassCliff

If it put out too much amperage - wouldn't it blow the main fuse isntead of damaging electrics?

Let's hope the fuse blows. :eek:

Let me know how it goes.

Note: When you connect battery to battery, there is no fuse in between.

Thank you for your indulgence,

The way the r/r on the bike works is that it will try to regulate the voltage, no matter what the source. If the voltage on the car's regulator is set just a bit higher than the bike's (and they typically are), the bike will try to regulate the car's voltage. Since the car can regulate itself, it sees the drop in voltage and compensates by boosing output. In a contest between a car's regulator and a bike's regulator, the bike usually loses. :(

.
 
I only ask because when I bought my bike, the battery was dead so it wouldn't start so the PO jumped it and I think the car was running. It wasn't hooked up for very long, and when the car's jumper cables were removed the bike ran off it's own charging system.

This is kind've derailing the thread though, I'll ask in PM's.
 
I think its a voltage thing, not an amperage thing, I don't think you can "force" more amps than a device can draw.

tomato tomaaahto as far as this is concerned though, hope you figure it out.

if you have fuel spark and air, then I dunno :confused:
