Fuckin choke tube!!

 

Was performing an air leak test and touched the nipple where the hose should have been and felt vaccume/pressure comming from the carbs.. Duh!! Grabbed a hose and connected it and walla, didnt need the choke anymore and it started perfect! Idled perfect! I adjusted the air screws and all is well..

 

So right now its running 340 mains, 27.5 pilots, needle set to center of 5 notches and air screws at 1 turn out. I still need to adjust either the needle setting or more adjustment on the air screws because I'm getting a bog on launch and have to raise rpm's to not stall. Will do a plug chop this weekend and see whats up. My temps here are around 55-75 degrees and @ 115 above sea level.

 

Thanks to all that helped me get through installing my mods and getting it all to run right! From broken cylinder studs to the damned choke tube, this site and you guys are GREAT!

Sometimes it's the simplest things that give the biggest rpoblems...at least the probelm has been found. The bog could be corrected with the air screw adjustments. I'd try that first before you tear into the carbs again.

Very glad to hear you figured it out....I guess you overlooked the choke tube when I asked you about it :tongue: I'd move the needle clip to the 4th postion from the blunt end and turn your air screws out to 2 turns and see how it runs. Congrats on fixing the bike, it's always a good feeling to resolve an issue :beer:

Yeah man you and a few others mentioned it as the first thing to check for, my dumb ass figured it was something more serious like bad reeds or my head being put on wrong. Its just that I upgraded soo many things at once I figured it one of them.

 

As for the needle there's only 5 notches, do you really think I should go to the 4th from the 3rd of the blunt end? Might be untrue but I was told with the vforce 3 reeds I should be able to go a notch leaner! I'll do a plug chop this weekend and get all of your opinions again if even the needle setting will show up on the chop.

I ran my needles on the 4th clip from the blunt end w/ T5's, reeds, Noss head, boyeson reeds, +4 timing, K&N in airbox w/ no lid, 290 mains, 27.5 pilots, and that's where it seemed to run best. Every setup is different though.

 

I wouldn't mess with the jetting for the reeds. You'll notice better throttle response more than HP gains with them, but that's just my opinion. :beer:

Are you running the Toomey needle's? The ones I removed were Toomey needles and I think they had 6 notches on them so I'm not sure if that will matter.. Actually how do I know which needles are better to run? Ones I have in there are from a Magnum jet kit and are red if that matters!

Never heard of red needles before, got me beat on that one. The needles I ran were stock. I was always told to keep the stock needles in there opposed to the Toomeys...no reason other than preference, I think more people were able to get their bikes running better with the stock ones....but I wouldn't take that as "fact".

Yeah thats the same reason I removed the ones in there... Wasnt sure if they were stock or from the toomey kit when the previous owner installed the pipes, I heard different stories about the toomey needles. I'll take a pic later and maybe someone would know the difference when they see it. If they are stock I'll prolly just reinstall them if others say they are better. Thanks for that bit of info,
