I will be sending my heads to you guys to work your magic! What is the turn around time on the Sledge head work I was quoted on, or is the quoted price for a set of heads already set up? I am looking forward to working with you guys to build my dream XL!

Atm all the plans i had have been halted(Intended to upgrade engine / paint everything / build stiff frame to continue the bobber style / continue tidy up electronics / new bars and rims) I'm tempted to just paint and slap it all together again instead. The basic 1250 or 1275 kits is what has been on my list. I guess the dream lives on for a little bit longer :D

Valve stem length won't change how much the valves open and close the lobe on the camshaft and the rocker arm ratio determines that ..
@HAMMERPERFORMANCE Жыл бұрын
Valve stem protrusion most definitely affects valve train geometry, and thus how much lift you get out of a set of cams. In a nutshell, to get max lift you need a stem protrusion that centers the rocker tip travel, so that at half lift, you have a right angle between the valve stem and a line drawn between the stem tip and the center of the rocker shaft. To the extent you vary from that, you'll get less lift than what's dictated by the lobe lift times the rocker ratio. Although it's a difficult thing to measure directly, there's a simple rule of thumb that gets you close: increase stem protrusion by half the amount you're increasing lift. So for example, if the factory stem protrusion spec is 1.900, and it comes from the factory with .500 lift cams, and you go installing .600 lift cams, you want a 1.950 stem protrusion. That keeps the rocker tip arc centered, thus giving you maximum lift. Some guys intentionally set stem protrusion a tad long, and then iterate, stacking rocker gaskets and measuring how much lift they're getting, until they find the gasket stack that gets them the maximum. This is generally only done on race motors, few street guys go to this extreme.

@@HAMMERPERFORMANCE You were not talking about valve stem Protruision .. You said Longer Valve Stems make it more likely for the valve to hit the Piston during valve overlap. This is not True. If you were to change where the valve seats are it could get the valves closer to the pistions. I built a 488 Cube BB Chevy Tall deck Truck engine for my C-65 Chevy I used a 4.25 stroke crank Longer Crower rods and stock flat top 454 chevy forged car pistons.. The second crane cam I used had I think .515 lift on the exhaust valves.. I had coil bind .. So i used shorter valve springs for a Clevland Ford.. Turns out the truck engines have shorter valve stems than car engines use.. The 427 chevy Truck engine only had .390 lift on the stock cam
@HAMMERPERFORMANCE Жыл бұрын
@@mikeskidmore6754 The longer stems found in 883 heads absolutely do reduce p-v clearance and therefore make them more likely to hit the piston during overlap. But it's not because the longer stems create more lift. It's because the valves start out closer to the pistons than they do with 1200 heads. Sorry if I wasn't clear on that point in the video. I thought it was obvious, my bad.

Did you guys ever do a video or discuss the heat difference between a stock 883 & a 1250/1275? Do they run hotter….enough to be concerned about? Looking at converting my XLH883 and am concerned about loosing reliability
@HAMMERPERFORMANCE2 жыл бұрын
There are a handful of reliability issues on the Evolution Sportster platform that pop-up when the power level is raised. None are related to heat, however. Good fixes exist for all of them. Many of the fixes came from HD themselves, and were rolled into the stock bikes over the years. So which reliability upgrades you need is a function of the year of your bike, and generally speaking, the newer it is, the fewer of those upgrades it needs. For a 2007+ bike, it's a pretty short list. For a 1991 bike, it's a pretty long list. Contact us for more details: www.hammerperf.com/contactus.shtml#salesform

The packages reflect the most cost effective way to reach their power levels. You can read about them here: www.hammerperf.com/883conversions.shtml#packages . Download the sample quotes to see everything included and what it costs. SLEDGE porting comes in at the 110+ level and BFH porting comes in at the 120+ level. Equivalency of stock 1200 heads varies depending on the year of the 1200 heads, but no stock 1200 heads come anywhere near the SLEDGE level. That's a serious level that makes for a really great head. SLEDGE and BFH are such major surgery to the heads that you can do it to either 883 heads or 1200 heads and they come out entirely equivalent.

1200 heads require the same level of head work to reach these high power levels as 883 heads do. It's such major surgery to the heads that it doesn't matter at all whether you start with 883 heads or 1200 heads, they come out identical either way. So if you're starting with an 883, there's no point in buying 1200 heads, you're just wasting money. Now sure, at the lower and mid range power levels, we approach it differently depending on whether the customer has an 883 or 1200. The idea is always to achieve the target power level in the most cost-effective way possible.

The focus here is all on increasing horsepower and performance. What about a guy like me who wants more torque and is willing to sacrifice performance for an engine that runs cooler and lasts longer? I just want to get down the road better with more speed and better handling.
@HAMMERPERFORMANCE3 жыл бұрын
Ultimately, torque is two things: Cylinder pressure and it's mechanical advantage on the crank (aka displacement). So to get more torque, you either have to raise cylinder pressure or raise displacement or both. Raising cylinder pressure increases the heat generated, it doesn't decrease it. So that's contradictory to your goal. Therefore I would suggest focusing on making the motor bigger. Since you're watching this video, I'm assuming you have an 883. The Basic Conversion Package is available in your choice of 1250 or 1275 displacements and either one delivers a massive increase in torque. Read all about it and also see the dyno sheets here: www.hammerperf.com/883conversions.shtml#basic .

On a 2013 XL883, a successful conversion requires the engine kit, a suitable tuner, a clutch upgrade, and a pair of the spark plugs we specify. In addition to those requirements, there are two recommended items: the ring gapping/preassembly service, and the Cometic EST top end gasket set.

Modern carbide seat cutters don't limit you to simple multi-angle seat profiles the way stones do. Sure, they can still do multiple angles, and in much better controlled sizes than stones. But they also allow you to precisely radius the area above and/or below the 45 degree sealing surface, which can have advantages depending on valve back cut and port shape. We use carbide seat cutters in this manner and have optimized the seat profile around the valves and the port design.

Your talking wizardry to me.. But it's cool that you know this much about engineering, please help me. I ride a 160hp monster s but just recently got a sportster 883 in mat black some eagle iron edition thing. It's the most beautiful HD bike in the best collor of the series to me, that's why i got it and also not to wake my neighbors up every night with that SC project flamethrower. But i find the ride of the HD equivalent to what i call a scooter, and would like to get 110 or 120hp out of it if i can. Is that posible and do you know someone in Europe who can help me do what you just showed us? Did you ever cooperate with someone from theses parts and what do you suggest?

@HAMMERPERFORMANCE5 жыл бұрын
99% of the time, our performance conversion packages are installed without any lower end upgrades. In fact, these kits can be installed in an afternoon without even pulling the engine out of the frame. Ridden normally, the kits have no effect on the reliability or longevity of the stock lower end. Spend a lot of time at high rpm and sure, you create a risk, but in normal riding there is no difference. However, for guys who want an upgrade and are willing to do a full tear-down, we offer this crank: www.hammerperf.com/images/newcrank.jpg . It's a massively improved crank with stronger rods, a bigger crankpin, and a bigger sprocket shaft. It's a bolt-in for 2004+ Sportsters, and we offer a retrofit service to install it in 91-03 bikes: www.hammerperf.com/xllowerend.shtml#crankconversion

how much does your mpgs suffer when you do the 883 to 1200 conversion?
@HAMMERPERFORMANCE3 жыл бұрын
Well, we don't sell 1200 conversions so I can't comment on that. But I can tell you that the majority of our customers report an improvement in fuel mileage after installing a 1250 or 1275 kit. You have to remember, the bike still needs the same power level to go a given speed as it did before the conversion. For example, if it needed 15hp to go 60mph before the conversion, it still needs 15hp to go 60mph after the conversion. You're in control of that power with your right hand. You're going to automatically apply the correct amount of throttle to make 15hp and go 60mph. The fact that it can make a whole lot more if you open up the throttle is really irrelevant to the fuel mileage when cruising. At the end of the day, fuel mileage is a function of how efficiently the motor turns fuel into power, not how much power the motor is capable of making. The efficiency gains you get from raising compression, which is a part of almost every conversion, can actually cause an improvement in fuel mileage.

Is it normal to experience increased valve train/rocker noise after the conversion? Is it because of the pushrods not being adjustable?
@HAMMERPERFORMANCE5 жыл бұрын
There are a ton of different things that can cause excessive valvetrain noise. Incorrect pushrod length is one of many possible causes. When using hydraulic lifters, the pushrod length must preload the lifter plunger an amount that keeps it in it's self-adjusting range over the range of top end growth the motor encounters. But that can be accomplished just fine without adjustable pushrods. Adjustable pushrods may be the easiest way to do it, but certainly not the best way. A non-adjustable pushrod of the correct length is the best solution, in terms of cost, strength, weight, simplicity, and reliability. We offer non-adjustable pushrods in a variety of lengths and we show three different methods for determining the correct length in this tech article: www.hammerperf.com/ttpushrodlength.shtml . When we put together a package, we select pushrod length using method #1, and we suggest the customer check it during assembly using method #2.

You will never see 140ftlbs of torque on a stock set of engine cases. They just don't support the displacement required. The best you can do is 90cu in and around 110-115ft lbs, depending on cam choice. That requires the cases to be taken apart and bored out. On stock cases, with stock 2004+ 1200 heads and a 1275cc big bore kit you can get over 90ft-lbs and 100hp with Hammer's 570 cams, which I think is the best cost/benefit right now for a torque oriented setup.
@HAMMERPERFORMANCE5 жыл бұрын
@@depthsounderdave David is exactly right on all counts. Fundamentally, engine torque comes from two things: cylinder pressure and it's mechanical advantage on the crank. Available fuel and cooling capacity place limits on the cylinder pressure, even if you can achieve the cylinder fill you'd need. "Mechanical advantage on the crank" is a fancy way of saying "displacement". So to make that much engine torque, at a workable cylinder pressure, you have to make the motor big. The stock cases limit how big you can make it. At stock motor height, 90ci is the practical limit, which is capable of putting you right into the range David mentioned. You can go bigger by combining bore with stroke, but the motor will be taller and won't fit in the stock chassis without frame mods. And 140ft-lbs would take a very big motor on anything resembling pump gas. Any motor build bigger than1275 requires a full tear-down and lots of expensive parts, too. You can't hardly do a 90ci conversion for less than about $5K. A 1275 by comparison is a lot less expensive and can be installed in an afternoon without even pulling the engine out of the bike. I have no idea who David is, but he knows what he's talking about. If you really want 140ft-lbs, you should go get a Big Twin and make the motor as big as possible. I think you'll end up disappointed if you try to make a Sportster run like a Big Twin. That's not what they're made for.

@HAMMERPERFORMANCE6 жыл бұрын
If you've got an 883 and you want more power, the best, most cost effective path is to modify your 883 heads. The beauty of 883 heads is they have a lot of material in all the right places and that allows us to make a really great head out of them. We've made over 130hp at 1275cc using 883 heads! So all of our performance conversion packages are based on modifying your 883 heads. See the packages here: www.hammerperf.com/883conversions.shtml#packages Now, that said, if you really want to do the conversion with 1200 heads instead, avoid the the 98-03 1200S head like the plague. It's not a "Thunderstorm" at all, it's a dual plugged version of the 96-98 Buell "Lightning" head, so named because it was first introduced on the 1996 Buell S1 Lightning. This head has the same small 1.720/1.480 valve sizes as found on the standard 88-03 XL1200 hemi heads, as well as the same crappy ports. Really the only difference between a standard 1200 hemi head and a Lightning head is some additional material in the chambers to reduce the chamber volume and raise compression to about 10:1 when used with flat tops. The Thunderstorm on the other hand was the second generation XL performance head, introduced on certain Buells in 1998 and then all of them beginning in 1999 and extending through the end of the tube frame models in 2002. This was a MAJOR improvement over the Lightning head, with larger 1.810/1.575 valve sizes, much improved ports, and a chamber that does not shroud the valves so badly - compression was increased via the use of a small dome piston instead, and a squish band was added. So don't confuse the 98-03 1200S heads with the Thunderstorms. Two completely different animals. The 1200S "Lightning" heads are not in the same league with Thunderstorms and you should not spend money to get a set, not for a performance project anyway. The third generation of XL performance head is the XB head, as introduced on the 2003 Buell XB9 model, and then propagated to all XL1200's beginning in 2004. This head is significantly better than the Thunderstorms in several ways, and if you're doing a performance project, this is your best bet. The Thunderstorm was a great head in it's day, don't get me wrong, but it's day has passed. Read more here: www.hammerperf.com/ttxlheads.shtml

Will 505/515 cams with stock 883 heads cause clearance issues?
@HAMMERPERFORMANCE4 жыл бұрын
The Feuling 505/515 cams have very low TDC lifts (.150/.137) and therefore they create no issues with valve-to-valve or valve-to-piston clearance. However, the reason the cams have such low TDC lifts is because they have so little overlap (26 degrees), which will limit their power gains. Also, the relatively late 48 degree intake close point will move the powerband up the rpm scale at the expense of bottom end and mid range. So know what you're getting before you go with those cams.

Guys do it, but some have piston to valve contact, it really pushes the clearance. I guarantee you that you'll be much tighter than the recommended .050" intake and .080" exhaust clearance. It's not something we would ever put a customer into, simply because some percentage of them would have a problem.
