Hi All, I have an '06 Ulysses that has been in the shop for a month while they tried to figure out the cause of the rough running. Now they tell me the throttle body is cracked, which is causing the problem. I was able to order the part from Chicago Harley Davidson for $100 cheaper than my local dealer. My dealer tells me they'll put it on for me, but I'm considering just getting the bike and finishing it myself, as I am pretty tired of dealing with them. Is a throttle body hard to replace? I'm no mechanic, but I can do basic stuff. Any advice would be helpful. Thanks! | ||

I guess it all depends on how much patience you have. If you can do basic things, and have the tools to do it, you can replace a throttle body or anything else on these bikes. Take it one step at a time, and use the service manual. In my opinion, it's a pain in the neck, but still better than paying the dealer for a job I can do myself. Then again, I'm still working up the nerve to do the front end service on mine. | ||

My first thought is that maybe this is due (at least in part) to jugs that are misaligned or not snugged properly. | ||

I just replaced my intake seals this week end... due to a very stubborn bolt on the throttle body.. I ended up rotating the engine .. doing that makes it a pretty easy job. Rotating the engine is not difficult, just follow the service manual and be methodical..... Changed plugs etc.. while I was there.. much easier to change the rear this way  (Message edited by gamdh on April 14, 2010) | ||

Wow a cracked throttle body! That's weird. How would that even happen? | ||

I have no idea. The bike has been running rough ever since I got it. | ||

When you buy a TB,install it, and find out it's not the problem the dealer is off the hook. you bought the part! find another dealer, sound as they are guessing. If the throttle shaft broke(holding the butterfly) as mine did, the bike was unridable. If you would like to borrow my TB casting( uncracked) it shoud'nt be an issue for the shop to install, PM me, i don't think they' l like the idea Bob | ||

I actually thought about that after I posted that. It might not be worth saving the money if this doesn't fix the problem. If they do it and it finally fixes my bike, it might be worth a few extra bucks. If it doesn't fix it, I'll tell them to take it back out and I'll just go pick the bike up then. | ||

The TB is pretty easy to install. But I would recommend the intake manifold wrench from American Sport Bike and be sure to replace your seals. It isn't hard, but you do need to be gentle and take your time. You shouldn't have to rotate the engine, just the airbox cover and base. I can't recall if you'll need to remove the coil... It has been a while since I had mine out. | ||

The PITA you are talking about.....is that the throttle body bolt on the left side of the engine? I changed my seals at my son's house when I was down that way for Daytona. I simply put one of his home owner(someone bought this set for him for X-mas one year, he is a professional) in a vise and cut it off to about three and a half inches. I used another box end on it for leverage to break it loose and tighten it. Piece of cake! But then, it wasn't my wrench! When I was done with it I told him his wrench failed. It looked broken to me(except maybe for the hacksaw marks).  | ||

mental note....never loan Vern tools....  | ||

I use a cut-in-half 1/2" open end for the left side, and a piece of 1/4" allen wrench stuck in a 1/4" box end ignition wrench for the right side. Slow and tedious but it works, especially with those thick Genuine James seals. Anti-seize on the bolts helps. No fun, next time I rotate the engine. | ||

No fun, next time I rotate the engine. My gosh, I can't imagine removing the throttle body w/o rotating the engine. Hats off to you guys. --Doc |
