12:1? What cams are you running? What exactly is the problem you are having with the heads? Are you the one with the valve guide seal issues? If so and it has been checked by someone(twice), maybe you should look elsewhere for help. Sounds like the valve spring retainer to seal clearance may be off. Who is setting up the heads and the motor? If you would like some advise/help with this problem, just ask. | ||

Ryker, I know to get my STD's (which are tall) out, I have to take everything off the top. Taking the front Motor mount off the frame makes it a great deal easier as well. Because then, of course you can rotate the motor forward to gain more room. I am at home now, but you are welcome to call the shop and I will try to help you as much as I can. | ||
| Pammy |
Of course, I will be at the shop tomorrow. Thanks Sean. You are a jewel. How's the health? Good I hope. | ||

Pammy said: There is a product out called direct link that we can use to tune the Buells(I haven't tried it yet) Is this a means to alter the settings in a re-writeable ECM? for the "tubers" would this allow me to ditch the pc3? Assuming that I came to your shop for a proper dyno tune..... | ||

That is a wise decision. Thank you, I have honored your request. And thank you for deleting your initial post on the thread. It was problematic. Cooler heads prevail. Close one though. Ryker and others, I've taken the liberty of removing all related NRHS posts concerning the problematic issue. Please consider the issue closed. | ||
| Blake |
Ryker, As to your wondering about posts being deleted. I'm pretty sure that Aaron deleted his own initial post. I sure didn't. I removed both my and his subsequent posts per his request.  | ||
| Nrhs |
It may have been problematic, but it was true, as was everything I posted. And I'll prove it when the time comes. And a whole lot more. Here's a tip for you, Blake: People who steal usually also lie. | ||
| Blake |
True to your version? We'll see. I for one doubt it sincerely. Here's a tip for you, Aaron. Indignant, accusatory, judgmental people who abuse their friends, publicly impugn their integrity and toss them aside like a piece of dogshit, such people who disingenuously exploit others for personal gain, usually have trouble ever admitting error or wrongdoing.

That's been my observation, too. | ||
| Pammy |
Oldog,That's what I am lead to believe. We do it with other bikes so I see no reason that it isn't so. The FI system on the tube bikes is so scitzoid though, not real steady. PS...I hope I didn't get too technical with that 'scitzoid' comment...heehee | ||

12:1? yes 12:1 CP 30 degree domed pistons What cams are you running? andrews n80 What exactly is the problem you are having with the heads? front plug has fouled out on me. in neutral when I rev the engine up on the decreasing RPMS some smoke puffs out. and my swingarm stays sooty black as if my bike is a diesel. Are you the one with the valve guide seal issues? no not at all. I am new to this HD repair stuff never had to wrench on my XL or S1w. I am just body who purchased a used bike that had been abused. If so and it has been checked by someone(twice), need to get the head off of the bike first. Sounds like the valve spring retainer to seal clearance may be off. Who is setting up the heads and the motor? the previous owner but he had ridden the bike with the heads for at least 2k miles If you would like some advise/help with this problem, just ask. thanks soo much. From my internet research. not from my own actuall knowledge. 30 degree domed pistons allow for a higher compression on the same octane of fuel. And the huge N80 cam allows for some bleed off of pressure on the compression. So even though the piston are 12-1 the setup might be less. ?? the bike runs/did run on pump gas 91-93 octane. some pictures http://i8.photobucket.com/albums/a13/hit_by_a_cop/heads044.jpg | ||

Front head valves! intake valve intake valve2 (Message edited by ryker77 on October 13, 2005) | ||

XB fines are too dang large to fit one more of the head cooling fins being just too large. (Message edited by ryker77 on October 13, 2005) | ||

Dude, that valve pic is nasty!! You gotta be sucking oil past the valve guides with the big vacuum stroke on 12:1 compression. | ||
| Pammy |
Are you taking the rear head off first? that is a must. Then you can pass the front head back out the top. | ||
| Pammy |
That valve guide looks to have more issues that just the seal and by the pics, it looks as if the piston has touched the head. I have to run out for approx an hour but you can call me after that. 727-546-0889 | ||
| Ryker77 |
rear head out too! dang it!!!!! live and learn. I'll call once I figure out why me cell phone doesn't have a signal. (Message edited by ryker77 on October 13, 2005) | ||

Honey, you know you are going to have to take the cylinders off as well, don't you? You have open Pandora's box(in more ways than one) and you now have a lot of work to do young man. | ||
| Road_thing |
Pammy: What do you see that makes you say the piston has touched the head? To my (admittedly non-expert) eyes, it looks OK. Thanks in advance for schoolin' me! rt | ||
| Ryker77 |
take the cylinders off as well??? Son-of-a-gljfsu... do I have to remove the cylinders in order to remove the front head, is that why? looks like I've got a few options. 1- buy a valve spring compressor tool. leave the head in the frame and take the intake valve out, for inspection. with hopes that I find a bad valve seal. 2- put a hitch on my car, rent a trailer, and take a road trip down to Fla. get the bike repaired and tuned at the same time. but money is tight right now. 3- let the bike sit on the front poarch and looks like pure southern hillbilly till I can afford a 1250 kit to be installed by an expert! | ||

If you look at the (front head valves) picture. On the right hand side as the shelf bevels down to the chamber, there is a ledge there and on the ledge you can see some material removed, ever so slightly. That could be as the dome ramps up up too much for the shelf in the chamber. | ||

Pammy said: PS...I hope I didn't get too technical with that 'scitzoid' comment...heehee No worse than my referring to a usb to serial adapter as a "thingy"  I read some where that the 99 ECM can be re written, but the 00 and later tuber units can't no clarification was given as to why, or how it was determined. I have spoken briefly to the PC3 folks about the buell related product which I have on my sled They used the words "unstable" and "inconsistent" to describe the buell DDFI operation so 'scitzoid' makes sense to me.. I am new to FI bikes so I can't comment, to much on good or bad. My bike is ridable, and runs well for the most part, there are several aspects that are a little quirky especialy while coming up to O.T. or when the throttle is opened quickly, some of these maybe related to other issues, or just the nature of a V2 engine, I rode a carbed IL4 for more than a decade the 2 machines are vastly different animals as I see it I am still learning about the V2 The bike is now 4 years old and is going down for IRAN and PM this winter. There are dyno charts in the KV that show stock and modified for the stock ECM no PC3. Your comments would be of interest, I would not be looking for power but for best case A/F, all across the range, no pinging and crisper throttle response. The PC3 seems to work ok but it is some thing else to go wrong in the system so its removal would not be bad. | ||

I'll need to inspect the piston to for sign of contact. I see what pammy is talking about. But I had my hands all over the heads trying to get it out of the WRONG part of the frame, LOL..... So my fingers could have rubbed some of the soot off . Lets hope for the best. | ||
| Ryker77 |
close up picture of possible piston contact (Message edited by ryker77 on October 13, 2005) | ||
| Pammy |
Once you release the pressure on the cylinders you need to change the base gaskets. You have other options (Message edited by pammy on October 15, 2005) | ||
| Pammy |
I am not talking about the big scuff. But the edge of the shelf being touched. | ||
| Pammy |
I'll tell you one more thing, then I HAVE to get back to work. That pic of the valve guide looks very bad. It looks as if someone jammed it into the head. It looks as if there is aluminum pulled out of the head. If someone looked at that and didn't mention it to whomever owned the heads, then that is their bad. | ||
| Ryker77 |
inspected head and piston. I think its all good. I was able to simple rub with my finger and the soot smears around, on he head. The piston has no signs of contact. | ||
| Pammy |
I don't care for the early FI. I hate to disappoint anyone but you don't have alot to work with there. |
