When idling - heat from left exhaust, but not right?

[BigJimmyW13]

Ok it seems like there is only real heat coming from the left cylinder and not the right when idling. Is this normal? I'm running the green monster and pamco ignition. Compression seems fine.

Assuming both plugs, etc are good, the idle jet may be plugged...Does the right kick in when revved?

 

[BigJimmyW13]

Firstly, Welcome Eric. Thanks for the reply.

It sounds like it. It sounds muffled till revved.

Did you get your carb prob sorted or is this another bike ?

 

[BigJimmyW13]

Same bike. Different carbs.. :-D

 

[BigJimmyW13]

I think it's misfiring. The plugs are fouled. I'm gonna pick up some new plugs tomorrow and see if that helps. Either way I'm too frustrated now. I'm gonna finish up the wiring and have the local yamaha shop come pick her up and fine tune her.

The left exhaust pipe was turning red and the right was cool to the touch. And when the right started firing it was shooting flame.

 

[eric123]

Red sounds hot, therefore lean? I assume timing is spot on? Good idea on the plugs...When in doubt, put new plugs in...

Bigjimmy I had this problem on my 71 XS and i tried changing the plugs and all that good stuff but the problem stayed the same until I got a new ignition coil. So if new plugs don't fix it you could try testing your coils.

[eric123]

An easy test would be to swap the coils to the other side. If the problem follows the that coil........

 

[cheftay]

mmhm true that

 

[yamaman]

I think you've got a Pamco haven't you mate? In that case, just swap plug leads, see if the trouble follows you!

 

[BigJimmyW13]

Yeah I sure do, but I switched the plug leads and it's the same prob.

Thought i would save you from doing it. ............ You would have striped everything for hard tailing............ so could some dirt have got into the carbs or has the float got stuck on one side and not getting enough fuel.......... with the flames coming out it sounds like timing..................one of your advance timing weights not working properly.........air getting in past your boots causing the lean hot pipe.....

I agree with skull ,with the flames it sounds like a timing issue

Hi bigjimmyw13
was going to post the Youtube link for testing the ignition advance mechanism by Pete himself when I saw your video & yours looks fine
PamcoPete ignition advance check

 

[BigJimmyW13]

haha yeah thanks KevC. Tomorrow morning I have an appointment with my local guy that helps with the stuff I can't handle. At this point I'm beyond frustrated. So I am just trailering it up and taking it in to have the timing and fuel system checked and adjusted.

Thanks guys. I'll keep ya'll updated.

 

[crash]

Keep us posted on the problem

 

[BigJimmyW13]

I most certainly will!!

 

[BigJimmyW13]

Alright well the bike is now officially in the shop. So that's where I am at! The guy said that it shouldn't take more than 3 hours to do everything at $75 an hour that's pretty reasonable. So I ok'd it.

Is that with the dellortos or have you given up with them?
