""It's a Neuman Esser two stage CO2 gas compressor. The fun we have! "" Does it make a 'potato, potato, potato' sound, too? . | ||
| Tootal |
I hope not as that would mean we have a leak!! It's very quiet when unloaded but once fully loaded you can hear it working along with the clicking of the sixteen valves. The first stage takes the gas to 60 psi and the second stage takes it to 240 psi. | ||

Hey Doc, is that a double duty garage / operating room ? | ||

Hey Doc, is that a double duty garage / operating room ? Check out the photos of the Ducati rebuild and you'll see the scabrous old concrete floor. Mrs. Greg (w/help from 2nd son Keith) surprised me w/epoxy coating back in May. You know how it is...when one thing is nice you gotta clean up the rest. So new shelves, general "garagecleaning." Like many of you, our cars sit outside...  ...the garage is...  We had an EXCELLENT Thanksgiving celebration yesterday; our boys plus some current and former grad students. Gonna make some real progress on the Uly today and Saturday. I've shed any vestiges of BMW-lust that I had (don't worry, I have common sense, as well as a limited budget). | ||

Good to hear you had a great day. Nothing like getting away from your problems for while to refresh your attitude. We await your success!  | ||

Dr Greg That is one sweet truck you have park outside your garage!!! I'm a sucker for REAL trucks. No wax, wipers optional along with turn signals and chrome bits that fall off never to be replaced. The shark fin window's instead of AC is the true mark of one classy truck. PS That Ford Escort wagon brings back good times memories (Message edited by rotorhead on November 28, 2008) | ||

Good to hear from someone who knows a TRUCK. That, my friend, is a 1968 GMC 3/4-ton that my dad (the legendary "Duke" Starr) bought new in '68. I inherited it in 1986, and had the engine rebuilt (it sat a lot). It's a big-block (now a 402) "porcupine-head" (or "rat motor"). Heavy-duty everything. I hauled 5,000 lb of sand onetime and the loader operator couldn't believe it. The GMC has 70K original miles; interior immaculate. The '83 Escort is my 2nd son Keith's. He also has a hot-rod Mustang, but the Escort is his commuter (bought it for $400; it has 40K miles on it). I got the front EX valve out before I thought I better wash Uly between rain showers, so I strapped the engine up with a (hopefully stout) tie-down, and pushed him out to the driveway...  I don't know if I'll get as much done today as I'd like; my back is acting up (broken neck and femur in a 1972 bike crash). But I'll get Uly washed, get the heads apart and hopefully washed; maybe take a little break after that. Good to have fun again...the Sunday ride looks in jeopardy, but I have been known to play hooky (hookey?) on a Thursday (no classes). | ||

Darn that Uly looks naked and very trim! | ||

OK fellas, here's my last posting of the evening. Had a fairly productive day cleaning. Tomorrow is all reassembly. Here's some of the parts laid out (headers in the picture just for some color):  The mating surfaces are as CLEAN as I could get them. Not bad for 55,000+ miles, if I do say so meself... Here's the crankcase...likewise on those mating surfaces:  So now it's off to dinner (Mrs. Greg says Thanksgiving leftovers...yum!) All measurements (valve spring length, valve protrusion, etc.) within spec. Everything looks good. Cleaned a little more "spooge" from the intake ports. I'll work till about 7:00 p.m. tomorrow, then take time off to watch the (recorded) USC-Notre Dame game (I'm a USC alumnus...go Trojans!) Who knows...maybe I'll get it together tomorrow. I'm not sure this "blow-by-blow" posting is a very good idea---I'm sure most of you have much more important stuff to do---but it's given me an outlet for some of my frustration with the whole job. Like I indicated earlier...a lousy spark plug thread led to this?!? | ||

The blow by blow is a fantastic thing - I really appreciate it and am following each post <insert>! However the pristine nature of the garage is about to push me over the edge.... Good luck with the rest of the build! | ||
| Skinstains |
Did I read that right ? You're washing a bike with no jugs on it ? No wonder that operating room is so tidy...you're nuts. | ||
| Dr_greg |
You're washing a bike with no jugs on it ? Yeah, well, I did plug/mask off all open orifices and was quite gentle with the hand wash. I think it's OK. Mrs. Greg just built a fire in the wood stove out in the garage and I'll be starting the assembly shortly. I'll keep ya posted. | ||
| Dr_greg |
Time to start assembling the heads. Oil the valve stem, slip it through, and put a piece of Scotch tape over the keeper slots so they don't scar the valve seal:  Temporarily alone (doesn't happen often) I couldn't install the valve springs myself (homemade spring compressor requires three people to keep everything lined up) so I started inserting the pistons in the cylinders. Have to do it before installing wrist pins since my compressor is so tall:  Success! Actually it's not difficult. None of this is.  With some help, I got the heads assembled. Anything with stiff springs which need to be compressed is scary.  Back to the cylinders. Tap the piston out the bottom far enough to expose the wrist pin hole and tap the wrist pin in partway.  Next step (after washing a few more things) will be to actually install the cylinders. I'm in the middle of installing the rear cylinder, then I intend to take a break and have lunch. | ||

looking good, hope all goes well. | ||

One out of two ain't bad...  Getting the clip (wrist pin clip) in is always entertaining. I've done enough 2-stroke dirt bike top ends that I've got lots of stories to tell of "PIING"  and the blasted thing disappears! That's why I bought four new clips for two slots. And make darned sure rags are stuffed in the case. BTW, it's a good idea to install the pushrod cover at this point. You can pull the cylinder up and angle it slightly to get a better approach vector on the "inside" cap screws. | ||
| Dr_greg |
looking good, hope all goes well. Thanks. The one thing I'm paranoid about is forgetting something. Like getting a cylinder on and forgetting the base gasket. Or tightening down the rear valve cover, then seeing the cylinder head temperature sensor over on the bench.  But that's not gonna happen... | ||
| Dr_greg |
When installing the piston in the cylinder before the wrist pin, you've got to line it up with cylinder in place, then tap the pin through. I put vise-grips on all four studs to keep the cylinder level. The nightmare here is jarring the piston enough so the bottom piston ring pops out! Then you've gotta remove everything, get out the ring compressor, and go back to step 3. Wrist pin almost tapped fully into place:  Then you have the delightful task of getting the clip installed. Small screwdriver to pry it in is the easiest way, IMHO. Both cylinders installed! Whew...  Now it's time to head for the spa and relax. Afterwards I'll work for another hour or so, then watch USC and Notre Dame. Looks like I'll finish the bike Sunday afternoon; I work pretty slowly and carefully. But there'll be time to go for a little ride to check things out. Don't even mention the words oil leak. | ||

A successful day! Prost! I appreciate the head shot, I like the fact Erik decided to use a single bee hive valve spring. I put them on my HD. They work great and they are quiet! Enjoy the game. | ||
| Dr_greg |
Upon reflection, I don't think I'll put up any more pictures. With the heads together and the cylinders on, there's nothing more very interesting. The only difficult thing from here on is getting the blasted velocity stack back on...it's a PITA. I'll let you all know how things go tomorrow. If anyone has any questions concerning any phase of what I've done, feel free to send me a PM (or ask here). Thanks for all the support; I hope you've enjoyed the show. --Doc | ||
| Ourdee |
Thanks Dr, I like all the pics, maybe just one or 2 of the PITA velocity stack going in? | ||

Godspeed Doctor! | ||

Hey Doc. can you tell me which model PIAA lights you have there. I'm seriously considering those for my Uly, but I'm not sure which model a)puts out the most light and b)won't damage the charging system. Any advice? Cheers. A- | ||
| Dr_greg |
I like all the pics, maybe just one or 2 of the PITA velocity stack going in? Well, it doesn't really go in, it gets "wrestled on." The last time I installed it my son held the clamp open while I wrestled it on. There's really no "photo op" on the darn thing. Sorry. Hey Doc. can you tell me which model PIAA lights you have there. I'm seriously considering those for my Uly, but I'm not sure which model a)puts out the most light and b)won't damage the charging system. Any advice? The PIAA's are the 5164 510 series. I'm embarrassed to say that since installing them (about two days before my spark plug blowout) I actually haven't been able to ride at night (given my recent photo history I'm sure you understand). I'll hopefully take a ride tomorrow that will extend into the evening so I'll have something to report. | ||
| Hangetsu |
Thanks. Why did you choose that particular model? I notices there are several which are the same size, but have different watt ratings. For example; 35W=60W (as the 510s), 55W=110W, etc. Is there an issue with auxiliary lighting concerning the draw on the charging system and perhaps damaging the stator? A- | ||
| Dr_greg |
Why did you choose that particular model? No rationale for that model choice; just a stab in the dark. Uh, no pun intended. I'll pass along my opinion in another discussion. | ||
| Dr_greg |
While I've not encountered anything that was definitely the source of the oil leak; I have noticed that the gaskets seem to fit better than before. That can't hurt. Plus I've borrowed a nice "clicker" torque wrench; much easier to use, and almost certainly more accurate. | ||
| Tootal |
Does Buell use the HD 16 lbs torque plus 90 degree turn on the heads? | ||
| Tipsymcstagger |
Dr. Greg...don't want to drive you crazy now that it appears the engine is back together...but did you install new rings? Reusing rings once the piston has been removed from the jugg isn't the best idea. Very small cracks can develop if the rings are expanded and then recompressed. I've always installed new rings if I've had to remove the piston from the cylinder. Tipsy | ||

Does Buell use the HD 16 lbs torque plus 90 degree turn on the heads? Yes. Dr. Greg...don't want to drive you crazy now that it appears the engine is back together...but did you install new rings? Nope; used the original rings. I anticipated doing the top end before 100K miles; I'd be replacing rings at that point anyway. We'll see how it goes from 55K to 100K miles. P.S. If anyone else has any "don't want to drive you crazy" ideas...keep them to yourself!  --Doc |
