Im having trouble removing the throttle body due to access and tools. I then re-read the manual which says, 'remove the throttle body velocity stack eg. the rubber bit'. Now Im thinking i should leave it until the engine is rotated down, then try it. Otherwise i need a midgit with powerful torquey-hands. | ||

The velocity stack only requires two small allen head screws to be removed, comes right out. The metal bracket that holds the stack also holds the injectors and fuel rail, I did not need to remove that part when I rotated the engine. The stack does hit the frame so it should be removed to fully rotate the engine. | ||

Don't pull the throttle body until you need to. Heck, I still have the rubber intake horn and just mash it against the frame when I rotate the engine forward. | ||

I have to add that I'm a lazy, ham-fisted mechanic. I have to rotate the motor pretty often. I also put the bottom of the airbox down on TOP of the rubber collar around the intake (normally the collar snaps into the bottom of the airbox) | ||

they throttle body will be coming off eventually. I thought it might be easier to do once the engine is rotated down as the allen bolts arent budging and there isnt much room to move with the frame in the way. | ||

Getting the stack off will give you a little more room, mine came right off and I'm pretty sure I just used an L wrench to get the screws out. It may be easier with it rotated, haven't really tried so I can't comment on a TB replacement/service. | ||

Greg, your info only applies to the 03 9. | ||

I'll have to look more closely at the 12 TB I have in a box, thought it looked identical but maybe I'm wrong. | ||

Its easier to take off the TB after you rotate the engine down. | ||

So....hang on.... Im getting lost here. All I want to know is, can i rotate the engine down with the TB still intact and then take it off? Im worried it will hit the frame as it is rotated down and therefore has to be removed first. Im having trouble finding non-metric sized tools here, especially ones that have to fit in the tiny space required to remove the TB bolts. | ||

The rubber stack will hit the frame but being rubber will just bend out of the way. Like Slaughter, we used to rotate the engine very regularly on our race bike and I never removed the TB or rubber inlet to do it. Why do you want to remove the Throttle body anyway (just out of interest)? | ||

Thanks all for the help. Trojan- I have a noise coming from the engine. Some say its the front conrod some say its a rocker arm. Either way im going in to take a look. | ||

remove the throttle cables! me & my buddy found this out the hard way, they broke. at least on the uly | ||

remove the throttle cables! me & my buddy found this out the hard way, they broke. You don't need to remove the throttle cables usually when rotating the engine (unless you go to far of course) but slackening or removing the clutch cable can certainly help. If you are wanting to get into the rockers then you don't have to remove the throttle body, and will only have to lower the engine slightly to get to the rocker covers. If you want to remove the heads then you can take off the throttle body and manifold complete without having lower the motor all the way. |
