If it is happening with two carbs I am going to be ther is a vacuum leak the lack of carb signal has lead to increased fuel getting to the cylinder and fouled the plugs, when you put t under load ther is no transition for idle to full open due to the vacuum leak and the plugs are week cause they are very wet. Wardens on his way to the store, for some carb cleaner, or ether, to check for a leak at the manifold to head flanges, we'll see what happens. I told him to leave the air cleaner off, and spray around the flanges, so he could wiggle the carb and see if it opens a leak there somewhere.   Logged     Last Edit: 2013/06/06 19:41 By SKWEARpeg.     The administrator has disabled public write access. #644740 WHITE_KNIGHT (User) Platinum Boarder Posts: 1231 Re:We have a stumper..maybe need some input 4 Years, 8 Months ago   I have a 01 roadie, put 42mm carb on from s@s removed fuel screen inside of gas tank, using stock pet cock, run gas line straight to carb with inline fiter of coarse,didnt vent gas cap, only removed roll over valve in vent tube that hooks at top right side of tank and runs down right side frame rail turns down in front of battery vents straight down in holder.

Same issues. No difference. I'm thinking manifold air leak too. ? Heading to get some carb cleaner. Manifold looks good, but ?   Logged       The administrator has disabled public write access. #644754 Roger7886 (User) ا.لكافر فخور ΜΟΛΩΝ ΛΑΒΕ  Platinum Boarder Posts: 1522 Re:We have a stumper..maybe need some input 4 Years, 8 Months ago   Just to throw out some suggestions here, are you guys sure its not a spark issue? Or maybe got some bad gas last tank full? Just thinking here, but if ya tried two different carbs, I might start to peek elsewhere. Did the tps ever come off either carb? Could be misreading and shifting the spark curve to soon/late.   Logged     I was born An AR in my hands Behind the gun Ill make my final stand And thats why they call me Bad Company   The administrator has disabled public write access. #644755 smokescreens (User) lifes better riding twins Platinum Boarder Posts: 17430 Re:We have a stumper..maybe need some input 4 Years, 8 Months ago   Warden wrote: For giggles, I hooked the fuel pump back up just to rule that out.

Check the plumbing or the cap on the manifold. Very well could be a air leak but even the tone of the motors idle would change (faster and kinda raspy)   Logged       The administrator has disabled public write access. #644765 DAVECS1 (Visitor) Gold Boarder Posts: 662 Re:We have a stumper..maybe need some input 4 Years, 8 Months ago   A vacuum gauge would tell you a lot, Probably going to need new plugs either way.   Logged       The administrator has disabled public write access. #644774 Warden (Moderator) Moderator Posts: 9535 Re:We have a stumper..maybe need some input 4 Years, 8 Months ago   I regret that I think I'm beat. This one had me stumped for sure. I regret the timing, as my trusty ride (never failed me in 5 years) will not get me to Green Bay tomorrow. On a positive, my truck loaded with coolers, awning, chairs, and a party will make the two hour DRIVE. Gotta make the most! Thanks to everyone's input. Especially SKWEARpeg who has been at the ready and made me fully competent in carb mechanics. I've learned a hell of a lot in a few short days!!! You are a true friend!!!! Thank you.   Logged       The administrator has disabled public write access. #644778 jd750ace (User) Front toward enemy Platinum Boarder Posts: 18763 Re:We have a stumper..maybe need some input 4 Years, 8 Months ago   Sorry it didn't get sorted for you Jim. It certainly sounds like it's leaning out on you from the description. You will not miss the party though. Gonna be a lot of disappointed folks that wanted to eyeball that paint job.   Logged       The administrator has disabled public write access. #644781 scooter76 (User) Platinum Boarder Posts: 2977 Re:We have a stumper..maybe need some input 4 Years, 8 Months ago   No worries, you're in good company.

Fate has a way of directing things that way with help from above.   Logged       The administrator has disabled public write access.
