Does anyone have any idea of how much a replacement front cylinder head will cost me? I've had no luck in getting the broken exhaust stud out of my front head and I'm considering just replacing it rather than messing with it any more. I sent DaveS a PM, but thought I would also just ask the forum. Thanks. | ||

Someone said they are the same as the 2004 and up 1200 sportsers , But I never checked and I don`t think they are, I`m just talking about the bare bones head no inners etc.?? | ||
| Espcustoms |
Yeah, just the head. I'll swap out everything else except for the obvious gasket. I actually haven't looked at the FSM yet to see what all will be involved. All I know is that it will be a LOT just to get rid of a broken stud! | ||

Well if you're gonna take the head off anyway, save some of that money and take the head to a machine shop. They'll be able to get that stud out for you, at less the cost of a new head I'd bet. | ||
| Espcustoms |
Well, that's what I want to compare - the cost of having a machine shop take out the broken stud and put in a helicoil vs. just replacing the whole head. In my area, it might not be that much different. Especially since the stud is broken off halfway into the hole and my easy-out broke off in the stud! | ||

Plus I don`t think one can buy just a bare bones head they come complete, not sure though... | ||

The heads do not come complete. They come bare. You need to swap all the parts to the new head. | ||

I'll just have to make a decision once I find out what the cost of the head is. I saw sportster heads on ebay pretty cheap so I'm hoping that this one will not be too far off. Either way, it looks like I'll be starting the process of getting the head off tonight. I'm not looking forward to this project. | ||

If it's the front cylinder head, it won't mount. Not sure about the rear. Especially since the stud is broken off halfway into the hole and my easy-out broke off in the stud!OH NO! Good luck, I hope you don't have too much more trouble. | ||

I wouldn't swap just one head out. There may be differences in chamber volume, dimensions or flow and then they would not match. If ya have to change a head, change a set. Any competent machine shop should be able to extract a broken stud. | ||

Didn't think of that  No doubt, XB heads are generations ahead of Sportster heads. Sheesh, I must be getting senile... | ||

rather than BUYING a third head, why not remove the two heads that you already have, box them up, and ship them to one of our professional head porting services, who can undoubtedly replace the stud, and freshen up your valve seats, and maybe port you up some more horsepower at the same time? | ||

I believe a head is in the neighborhood of $300. Take the head to a machine shop and have them drill out the stud - much cheaper. | ||

Fullpower is right on the money. If I was to be in your shoes both would be pulled and sent out to Revolution for the repair and small port flow. It would make the work you already have to do that much more enjoyable and pleasing with the results. | ||

I agree with fullpower do it right and send both out to get a work over- summer is over anyways. O I see you live in Cali, good luck with the project. | ||

I work on antique bikes all the time. You can't buy certain items "new" like heads, barrels, etc. So when I have a head "problem" I MUST send it to a machine shop. Broken studs, missing threads, broken fins, broken off threads, cracked head, etc... Otherwise, I have an ornament and not a motorcycle. Send it to Brian's shop, one of our sponsors, and let him do his magic. AND... it's cheaper. I work on alot of Norton's. Heads are becoming scarce. I had to pay $500 for a "good" head for my '75 850... it's a long story. Let's just say I would have saved myself alot of time and grief if I had just sent my head out to a machine shop and had it fixed in the first place. | ||

Thanks for the input guys. I'll be getting the head off in the next couple of days and will be sending it to a machine shop I was referred to by a friend last night. Hopefully, this will all go fairly smooth and I'll be back up and running soon. | ||

Bolt extraction with or without helicoil shouldnt be too much for than $100. Theres a good chance they can mill the broken off part flat, center drill and then drill with undersized left hand drill. If your lucky the bolt will turn right out. |
