Runaway shee during Idle

Recommended Posts

I think all of it has risen from the change in the cable and then experimenting from there with out addressing the original issue. I was wrong about idle, its not set, not sure why it ran good the one start but now it is def not.

 

Does anyone know what the result is of gapping out the cable from the lid of the carb is? I need to start there.

Ok, found the source of most of the problems. Damn pilot was wrong lol. Got it set but now only left cylinder is firing, wont stay running like that either. Right cylander doesnt look like its even getting fuel, which doesnt make sense because its a 2 into 1 setup.

Im going to clean all of this up to make it more clear, I have been all over the place with this and it seems that I have multiple issue, but someone might know where I should start if I explain everything that has happened.

 

At first when I got the bike back together it fired. and ran but was running out lean. after but loads of trial and error I found that during my rebuild I had mixed up the pilot jets and put in the wrong one. I had put in one that is 1 size up from what it was running before. I may have caused an issue with all of the overfueling / testing that has caused my current issue. The quad is only running on the left side now. Currently I am back to my old setup that was running before the rebuild.

 

Bike info.

 

bored out 30 over, heads shaved 14, toomey T5 pipes and 2 into 1 carb kit with a keihin 35mm carb. Almost all of the issues posted about before where probably attributed to having the wrong pilot in wile i fluttered around with the mains and the airscrew to no / little success.

 

Now I have swapped back to the correct setup that was running before and the bike has stop running on the right hand side.

 

Tests so far to troublesoot.

 

I have swapped both plugs while keeping the wires the same / then I have swaped the wires while keeping the plugs the same and tested each condition. No luck, still only firing on the left hand side. Left hand side will not runn solo and it "boggs out" im not sure if this is common but im guesing it wont run on one side? if it will then I have more issues.

 

Since its a 2 into 1 I cannot figure why it would only fire on one side due to a carb issue. Maybe a weak read? Maybe during my testing I caused an issue with the piston?

 

When kicked both sides still have comprssion. I rolled it down a hill and tryd to fire it and no luck, but I was able to see that I am getting fuel on both sides and after testing the plugs and wires I find that both have spark in every variation of plug / cap / wire combination.

 

Could it be that there may be an air leak on the right side and the fuel / air mix is not enough to fire it?

 

could it be that when I whent back to my old pilot jet wich is 1 size smaller that its not getting enough fuel to that side with the combination of having a possible air leak?

 

Is it possible for a stator issue to only effect one side even when swapping everyting around to all positions with still no fire? Seems like that would be weird.

 

Thanks for any help / ignore any posts above this point as they dont target the primary issue and are due to my mishap of using a more rich setup then I needed.

For some reason I cannot edit my post above, more than 1 time?

 

Wanted to make this more clear

 

the reason it was running out lean at first was because I was trying to rejet for summer on my main but wasnt running well because I had the wrong pilot in while trying to rejet the main. This caused most of my confusions. I had put in one that is 1 size up from what it was running before. I may have caused an issue with all of the overfueling / testing and attempting to lean out more on my main while not giving enough fuel on the idle, this may have caused my current issues?

OMG, crank is leaking into the right cylinder, Just filled it, new outer seal, level is now very low, none was lost from outer case.... This explains alot... and sux.

 

which seal would it be?  and could this cause any major issues? This makes alot of sense since I thought i was fouling plugs, after figureing this out, I tested all of the plugs that I thought was fouled, they all work lmao.

 

ok so if this didnt do any major damage, I should be good after fixing the crank seal, is it an easy fix?

 

Was probably why I couldnt find my tune, and it would sometimes runs like a beast then go back to shit.

No I did not, tbh I probably cleaned it off. Ill explain why im so stupid and did that lol. The previouse owner put liquid sealant on everything, even the outer cover. Instead of using gaskets, So when I put it back together the keyway was just a o ring after my cleaning frenzy, i probably didnt seal it because the whole case was basically a oil / liquid sealant 50 / 50 mix type gunk lol. Im guessing I should just get some liquid sealant and seal it then? How will I get the already flooded oil out of the right cylinder though? i could put the bigger jet back on and run it out because it seems that adding more fuel was the reason for it fireing before. But was just super sloppy because the oil mix was so high.
