Engine running on 1 cylinder! Help.

[mister]

did you check out the diaphrams on top of carbs ,one of mine crapped out at only 10,000 miles  .would have expected it to last longer.

Is that 10,000 miles that You put on the bike?

As soon as the bike has a Previous Owner or Owners, all bets are off as to the expected life of anything cause you just don't know what heinous things the bike has been subjected to.

I'm almost at 44,000km on my bike and she's still sweet as. No problems. Then again, I've put them all on the bike and haven't tried to fix anything that wasn't broke.

Both diaphrams were visibly okay.. No splits or anything..

I have ordered a Generator rotor as this needs to be fixed... As the charging system is working and i found 2 magnets loose..

Just need to know which way the bolt comes off that holds the rotor on... As getting it off can be a bit tricky without the correct tools..

I had these issues as well. I went around in circles until I read to start with the basics, which was great advise since I didn't even know what the basics were. . So after finding out what they were I proceded to trouble shoot.

I would start with the easy stuff first:

Do you have spark? Take your spark plug out and stick it in the boot. Make sure you remove the other spark plug "unless you want it to start". hold the spark plug that is in the boot close to the cylinder head and crank engine.

Do you have spark?

Do you have compression? Stick your thumb over the cylinder in question "again making sure the other spark plug has been removed" proceed to crank the engine. Does it push or pop your finger off or out of the spark plug hole? Do the other side to compare compression. Does it feel the same on both sides?

Do you have compression?

The last basic thing to check would be your carbs. If thats the problem there are plenty of treads on this site that you can search that will help you with carb problems.

My problem was a mix of compression which i had a little bit of and carbs. solved problem with shims, valves and a good carb cleaning. Hope this info helps.

Oh yea make sure your slides aren't sticking open. I checked mine by running with the air box off when I was trouble shooting air/fuel mixture issues. left slide would stick on hard rev. found that the spring in diaphragm was getting kinked up

Thanks for your reply...

I have a decent spark from both plugs...

Havent checked compression yet as i have a rubber cone type one and it didnt want to read properly... I am going to borrow a screw in type... And at the moment i cant check compression as of yet because i have it in pieces as im just replacing the Generator rotor..

But once thats on i will check compression, hopefully have the bike running on its own battery by then, as the there is a fault in the charging system. Hopefully wont have to replace the Stator too, but there doesnt seem to be any damage caused to it by the magnets and it looks in good condition...

The carbs i have taken apart and cleaned up inside, which they had quite a bit of brown dust type stuff in there... As for the sliders sticking, i think the carbs are okay.

I have checked the clearances and they are okay, well both inlets was 0.06-7 and LH exhaust was 0.08 and RH exhaust was 0.11... Which i know doesnt fall under the 0.03-0.07 allowance, but for the exhaust valve clearance i have been told this is okay....

Need to know what i can get the generator rotor off with... Im not sure what size the thread is so i was thinking to get this..
