Re: Carb problems following needle shim mod
 

Welcome to the forum. Get used to it.

Do not use 91 octane, the bike is designed for regular gas, 87 octane. That may be part of your problem. Empty out the gas and put it into your car and put in fresh regular gas.
If after you switch to regular gas it still runs rough, why don't you then replace the new spring for the carb? it may be a touch out of spec or hanging up on something in there.
If the bike was running fine before you did the mod, and runs like crap after you did and then undid it, it has to be something you did, right? Retrace your steps, look again for air leaks. The fresh gas and new spring may fix it.

Re: Carb problems following needle shim mod
 

And just who do you think posted messages that caused it to "deteriorate" the most ??

You're right; I had nothing additional to offer.....partly since it appeared that you had already figured out what the most likely cause IS and were going about correcting that.

And here's a news flash for you: Sometimes we post messages to just "discuss" things. That kind of keeps the topic fresh while we wait for someone else to chime in......or in your case, we wait for your "fix" to be implemented to see the result.

Sometimes someone mentions a tiny little thing that triggers a memory from someone else........in a post that didn't directly address the original problem. Sometimes the OP fails to mention critical details and just chatting brings them out.

I am sorry that you took my post in a light that it was NOT intended. I am not sorrry, however, that I made the post.

I hope you get the bike fixed soon. I will darken your door no more.

Just stating a fact. :neener:

P.S. You and Dupo BOTH should be ashamed of yourselves for cluttering up this man's thread with messages that contribute NOTHING to helping him fix his problem. Shame, shame....... :facepalm:

Re: Carb problems following needle shim mod
 

I'm not sure where I read it on here, but I'd swear I read that 91 octane was the way to go. I will dump the gas and refill with 87. I'm really glad to know that. Thanks mrlmd1. After doing a search under "octane" it looks like it may be the partial cause of my problem, especially since the higher altitude makes the octane rating equivalent higher. 85 is the standard low octane here, not 87 like in Ohio where I grew up. In addition, I read that some people feel that Seafoam will raise the octane of the gas a little more. Not sure if this is true, but It will be long gone with the new tank of gas.
Since the spring is on the way I'll give it a go when it gets here. I played with things a little more today and then fired it up. It was rough for about 30 seconds or so and then was actually running great for a little bit. I took it for a spin around the block and it started to falter again. I limped it home and it stalled out in the driveway. I pulled the carb cap off and found that the needle had been thrown up and the plastic spring holder and the spring where removed from the needle and laying beside it in the carb. It makes me think that the slight imperfection in the spring is allowing the plastic needle holder to catch on the carb cap and get flung out of place. I don't think the spring actually got ordered until this morning, and with the holiday on Monday, it probably won't be until the end of next week until I give it a go again, but I'd love to hear if there are any more thoughts on where the problem might be.

I keep going over everything I did and just can't come up with anything other than the spring. I spent some time with the blow-up of the carb to make sure I didn't accidently leave a piece out, buy I think I'm good there. I'll give another check for air leaks once I get the fuel replaced and the new spring in. Thanks.
