Caboose: Unless you love your dealer, fix it yourself, use a premium gasket, and forget about it! r-t | ||

Use the new steel gaskets from HD/Buell. Unless the lower box or top of the head is uneven, these new ones should solve the leak problem for a very long time. I would do both boxes at the same time. Gary | ||

Cabooser, Yes, they are covered under warranty. The new Buell gasket is "premium" quality too, so letting your dealer handle it is a good idea. Just make certain that they do indeed use the NEW style gasket. | ||
| Gcpoland |
The new style should be in all the kits now. HD sent the dealers extra metal ones to add to all their on shelf gasket kits. If you have a reputable dealer, they have added them to all their in stock kits. After they do the work, you can actually tell by looking, if they used the steel or not. All the dealers I know are using them because they solve all the "comebacks" for that style leak. Gary | ||

I was reading either Hot Rod Bikes or American Iron and noticed where Wiseco has come out with a big bore kit for Sportsters. (1400+cc) Has anyone had any experience with it? I checked their website but did not find a listing? Jeff | ||
| X1glider |
Jeff, like the other big bores, the spiggot holes will have to be bored larger. An inconvenience I wish the factory would accomodate us for out of the crate. | ||
| Sportyeric |
I could be hallucinating (I've been doing that a lot recently) but I thought I read somewhere that the 1400 kit used pancake pistons, where the skirts are so short they don't go into the cases so the cases don't have to be bored. Is that possible? And,if so, who would want the resulting longevity problem? | ||
| X1glider |
That doesn't sound good. Short pistons that would rock in the bore. And the area of the piston face would be greater than the area of the small end of the cylinder. The piston would try to push more air thru that same size hole. The engine would be fighting against itself. I'd stay away from that. I couldn't get into the HD side of the Wiseco site to verify if that's what they really did. Can't imagine they would. | ||
| Sportyeric |
I'm never sure whether its better to hold one's peace until you know what your talking about or shoot from the hip in the hopes of being the first to sound knowledgable. But isn't it F1 technology to use such pistons? I'm trying to remember how far above the case the wrist pin is at BDC. As I said earlier, I may be suffering false memory syndrome or something. But why else the buzz about 1400? That not a big deal for a big bore , is it? That's about 86ci, I thought 88ci was somewhat standard. I guess someone who's actually read the article in question should pipe up soon.  | ||

Regarding the Wiseco bigbore kit mentioned and shown with a photo in Hot Rod Bikes,as a 1400cc kit for Sportsters.The photo shows a cylinder with a "spigot" that would go down into the cases + the caption reads like the new cyl.kit uses a nickel-silicon bore.I just checked Wisecos website+its been redone in the last couple days. It shows the 84cu.in.?1426cc?(calls 84in.1375cc on sportsters?)Anyway,they show a kit that includes cyls.+pistons for T-storm head Buells with 10.5-1 or 12-1 compression+ seem to list the cases as needing bored,I couldnt find anything about the cyl.lining material on their website, though that may just be me.It all sounds pretty interesting though. | ||

Blake,i guess i either show my computer ignorance right now or keep making posts with the words stopping way before the margins like in my post above.Im really new to computers,what am i doing wrong?  Wait til i try to post a photo  Thanks John | ||

You're hitting the enter key unnecessarily ... just let the words wrap on their own, and hit enter twice when you want to make a new paragraph. WRT to this whole notion of a big-bore that doesn't require case boring ... let me ask this ... if the spigot was small, and the piston skirts were so short that they didn't get pulled down into the spigot (hah), how would you install the pistons? You ain't gonna put them in the top, you won't get the wrist pin in. | ||
| X1glider |
Funny how the most obvious things get overlooked. I guess Aaron's tidbit of info ends the Wiseco topic. | ||
| Jrh |
Aaron You are correct again,Thanks John | ||
| Blake |
Couldn't you just install the pistons then slide the cylinders down over them?  Without a spigot, would the base gaskets be prone to leak? Would the cylinder be prone to misalignment during installation and shifting during operation?  | ||
| Aaron |
Oh. I assumed a stock diameter spigot, therefore not allowing the piston to be installed from the bottom. No spigot at all, that's different. You're right, that's a different set of problems. | ||

Talked to my dealer, he said it'd be 10 days before I could get in for service, busy shop. I can't go that long without riding my bike so I picked-up the rocker box gasket kit with the new metal gaskets and did the install myself. Everything went off without a hitch. One of the final steps is to pour oil over the rocker arms etc. I did so and put the upper box back on. The bike sat for sometime before I started it. When I finally did start it there was a lot of clatter coming from the front and rear rocker boxes. I shut the bike off and wondered what the hell?  Everything went in just the way it should (I have the shop manual)but here I sit guessing what might be the problem. Is it normal for the rockers to make noise until oil makes it to the top of the motor? Could it have something to do with the lifters (do they need to get "pumped up" ) and push rods? | ||
| Road_Thing |
Caboose: Sounds like valve clatter. Just a couple of shots in the dark... Did you make sure the pushrods went back in the same holes they came out of? They're different lengths and color coded; if they're in the wrong holes, the hydraulic lifters may not be able to take all the slack out. Did you spin the motor around to a crank position where there was no pressure on the pushrods before you put the rocker boxes back on? (i.e., were the lifters on the base circle of the cam?)If not, that also might leave you with slack in the valve adjustment. Good luck, let us know what you find out. r-t | ||
| Sportyeric |
Sorry for the BS, then. I guess my shots-to-goals raio is getting poor. I think the clattering lifters is normal and should go away after five minutes or so, assuming, as RT says, that the pushrods were installed in the right position. I've found they tend to rattle for longer than I would have expected. | ||
| Caboose |
After re-assuring myself that I put everything back together properly I fired the motor up again. Two - three minutes of chugging away at 1050RPM the clatter went away, revved her up a few times, all is well in my universe again!. I guess it was just a case of there not being any oil in the rocker boxes to insulate the noise inside. | ||
| Sportyeric |
That's an interesting theory but I think the noise is the lifters needing pumping up. I picture that the lifters fully extend when the pressure is off them, filling up with air as they do so. When the rocker box is re-installed, the air displaces (pushes out) the oil that should be there, had been there, at the same lifter plunger position. Probably just more of my uneducated BS, but it would explain where the oil went that requires them to be pumped up. No shots, no goals. | ||

Caboose, I just picked up the new metal gasket today for my rear rocker box...which side goes up? With the paper ones, the bead went up. The dealership said numbers up but I would like to find some documentation online to put in my manual. I apologize if this has already been covered...too much school!! v/r Tony | ||
| Caboose |
My dealer said the same. Numbers up.  | ||

   My M2's heads, in progress at Cycle-Rama. Getting a custom Wes Brown job, complete with custom matching pistons. Yes, I have permission to post these, they're far from finished, more and better stuff came along after these pictures. Big honkin' cams specified by Wes to go with them. Anticipation is running high! | ||
| Jmartz |
I hope those little black dots are not pits in the casting. | ||
| Peter |
!@#$%^&* I can see another expensive trip across the water to Bonneville coming up..... PPiA | ||
| Doncasto |
Wow! Wes is really giving the heads the "full voodoo" treatment. I still think he is doing all his flow work only under a full moon, with scented black candles, chanting midgets, dancing naked virgins (or semi-virgins, as circumstances dictate) . . . I'll bet the little black dots are just left over secret herbs and magic potion residue. | ||
| Buelliedan |
Actually I heard he has some Blonde in flannel underwear doing the dancing!!  | ||
| Pammy |
Little black dots are most likely fleks of titanium.... We do call Wes "the GREAT AND POWERFUL WIZARD" Pammy don't dance, I'm far from virginal and that would be burlap, not flannel....(let's keep the history straight)[that burlap remark must've been a slam on my perceived southern heritage?]Anyway I find it quite humorous still.  | ||

oops, I meant unobtanium |
