I know a lot of you have taken your headers off for whatever reason, jet hot, wrapping, etc.... I will be picking up a Micron system soon and I know I've read about some of you removing the rear header flange and O2 sensor without rotating the engine down (as per the manual). I dug through the KV and can't seem to find any of the posts. I really appreciate the help. Rich  | ||

Rotate the engine. Not nearly as difficult as it seems. For one thing, there is no reason to remove the fuel line or connections to the injectors. I speak from experience. Makes the access to the rear a lot easier. Just my opinion. Others may very. Good luck. | ||

YEah... rotate the engine. Piece of cake. | ||

I plan on attempting this stunt in spring with a forklift, rear stand and a 2000lb strap. Odds are it'll probably find its way into the back of my truck in a ton of pieces heading to Suburban Harley/Buell, but wtf, it's only money. Since I have the motor down, what else should get replaced so I/Suburban don't ever have to do this again? Plugs? O2 sensor? | ||

Dude... It's really not that hard. It's like six bolts or something. One thing you will need to do is loosen the coil. You don't need to remove it but loosen it because it will run into the frame a tad as you lower the engine. The other is remove the clutch cable at the lever (like a two minute job). If you REALLY don't want to mess with the clutch lever adjustment you can just take it out of it's cable holder and slide it around the edge of the primary case at just the right time (you'll know when it's the right time if you're lowering the engine slowly via a floor jack). It really is easy. I've done mine a number of times. The last time was a full engine pull and I'll bet I had it out in 20 minutes or so once I got the bike supported (because the swingarm goes with the engine but I wanted to leave it there...). Easy stuff. You'll be amazed. | ||

Buy the service manual, I was looking at it last night and it looks straight foward. It provides step by step instructions on how to take the header off by rotating the engine | ||

Look, trying to get it done without rotating the engine will only wasting time. Once you do it you'll laugh at the debate going on in your head about it. The first time I did it, it took about 45 minutes to rotate down, take the header off, put another header back on, and rotate the engine back up. | ||

After rolling Damnut's engine down this past August, I now roll every buell motor down to work on them. Even to change spark plugs. It's silly easy! | ||

The service manual instructions for engine rotation look daunting, and there are a lot of little bits and pieces to herd, but as others have stated, it's not that bad. You start just pulling pieces, and it feels like it was a lot of work, then you look at the clock and realize it has been less then 30 minutes. And as stated, you don't have to do half the stuff the manual says. From memory (dangerous, but maybe a helpful data point): 1) Support the bike on jack stands with a piece of rebar through the rear axle. 2) Pull airbox cover and baseplate. 3) Loosen coil (I just removed the bolts). 4) Remove clutch cable from lever side. 5) Remove left side footpeg bracket. 6) Remove exhaust can (which is a few other steps, I always carefully remove the tensioner but don't bother loosening the rear axle unless I have some other reason to remove the rear wheel, though this is probably foolish... I just always forget to do it before I put the bike on the jack stands, and don't want to pull it back off) 7) I removed clutch cable retainer wire thingy and removed throttle cables from the intake. I don't know if this was really necessary, but i know it wasn't hard. 8) Remove oil cooler bracket and let it float (don't remove oil lines). 9) Unplug O2 sensor (again, not sure it was necessary). 10) Support engine with floor jack. 11) Start removing engine mounts as per service manual. That front "Jesus Bolt" was last, and the engine won't start moving until then. 12) Slowly lower engine, circling the bike and looking top and bottom for things catching. Putting it all back together is even faster, just use appropriate torques and locktite. Getting the exhaust can off is probably 1/3 to 1/2 the job, if that helps put it in perspective. While you are in there, I would replace the spark plugs and look for rocker box leaks and inspect throttle cables for wear (both mine were frayed, but I like zero play and had run them too tight). Its a good time to inspect wiring harnesses and spark plug wires. As a side benefit, an O2 sensor wire that had been stretched fairly tight against the rear head since the bike was new, ended up nice and slack when I was done. Not sure how it changed, the routing looks about the same, but it ended up better then I started. There end up being lots of similar bolts to keep track of. I didn't bother, and hoped I would be able to work it all out, and I did, but keeping bolts from each "job" in separate bags would probably have been prudent (footpeg bracket bag, oil cooler bracket bag, airbox base bag, etc). | ||

Thanks for all of the input. I really appreciate it. The manual does make it look like some grueling task, that is why I asked if there was an easier way. But, since I got so many responses to how easy it is, I don't think I should have a problem. I'm a heavy machinery mechanic and don't usually play with my own stuff except for the Buell. I get so much great input here and fast responses, it would be hard to get stuck. Rocket, I will be removing the injector connections to install the Dobeck box, so that tip doesn't really apply, but thanks for pointing that out. Rich | ||

I wouldn't be at all suprised if you asked for some local talent to come by your place to assist you and got many offers of help. | ||

There isn't any one near me that I know of. I usually get my Ninja ridin' buddy to give me a hand. I'll get through it and let ya'll know how it went. It may be a while though. My job requires travel and I'm leaving for Charlotte tomorrow. I'll get to it when I get home. Rich | ||

ET, post in Carolina Corner Carvers when you get to Charlotte. We have some people around there. | ||
