Thanks a lot for this series. I love the way you do unedited filming with no ads and no interruption. Even YOU didnt know that valve was broken!! COOL!! Did you actually say that bike had done the TT a few times? It must cost a fortune to ship the bike back and forth from the USA?

[@HAMMERPERFORMANCE]

This bike is a customer of ours who is a marshal for the TT. So he has had a chance to run the course a hand full of times. He brought the bike to us for our 120+ HP package.

[@tattooglisha]

The best video on YT definitelly. Thank you and keep sportster line the best line in your company . That made you strong and will keep you there. Lots of companieas work on big twins and i know you will get there strong but i would like to see you on top in 20 years too. And i would like support and parts for us ,furst customers for 1250cc kit. Thanks again. P.s.Btw Cometic gaskets are great and reuseable on my suprise. Your gaskets and o rings and rubbers are great too! Nothing made me regret buying a kit. Its a world changer for bike. Its now race able vs. sport bikes on start and first 100-200 meters easy. Mileage stayed the same with normal riding while up when racing. Ofcourse. New customers should know that if they are not track racers they could easy over power their bike and it becomes bad ass but for some guys uncontrolable and higher idle makes them ask why it is like thst. But if you overpower bike youll get a bike that is throttle thirsty .

[@Ashroyer86]

I was pulling on gsxr600 and 600rr up to 3rd gear with my 1200. Not sure what work it had done to it but sure the 1250 kit would have helped. Would love it with the 1275 kit. Looking for another cheap sportster to build now.

[@micahlewis5]

Another excellent tutorial video, hiccups and all. That's how it really goes! Lots of little tips and tricks of the trade along the way really help. I learned a lot from this video, especially concerning TDC. This came just in time right before I disassemble my rear head for a gasket refresh. Keep on hammering away. Looking forward to assembly tutorial!

Back in the old days, I used to just put my finger on the spark plug hole, until I felt the compression starting to build up, then put the straw in the spark plug hole, to see where the piston is, as both rocker arms remained up. ~ Fernando

[@stevenweede7184]

Love your videos. I bought my bike because I was supposed to get an older classic car to rebuild with my dad but he passed in 2012. I don’t have the garage space so I got a rubber mount Sportster. Lots of parts available & one of the easier bikes to work on. What would you recommend would be the simplest cam upgrade for an ‘05 1200C? Just looking to get a little more power. Mostly on the low to midrange. After watching this video it seems like no matter what I have to remove the rocker covers & pushrods (& replace gaskets). So, what’s the best option for me to bolt in cams without having to chamfer any cases? Also, any other recommendations would be appreciated. Thanks guys

Slightly off topic question. What brand/part number is that massive oil filter, and can it work on a Sportster?

[@zechariahliszewski]

Is there a way to get TDC without the cams or transmission in? Would there be damage if those were taken out before top end disassembly?

Is the 88" kit well enough built to provide at or near OEM reliability as 883/1200cc motors?

[@danielleridlon]

Thank you SO MUCH for this video!! Am I okay to not disassemble my rockers if I only need to remove the cam cover, leaving the gears in place?

you will need to remove the rocker boxes to take pressure off the cams if you are going to remove the cams

Fantastic video

[@jaklyca8124]

Hi Dan great videos. I have a request. When I bought my 1250 kit from you I also bought the billet base kits for the stock pushrod tubes. However I never did fit them after I heard a lot of horror stories about how hard they are to fit. So not to slow me down I fitted the old single ones back. It would be great if you could include fitting the billet ones on one of the rebuild films. Mine are leaking so I must do them again soon. Thanks

[@HAMMERPERFORMANCE]

Hi Jak We will be doing a video on this soon. Keep an eye out!

[@cosmiccharlie8294]

Nice job, thanks!

[@jewballee]

How well do the stock 883 crank and connecting rods hold up to the power of the 1275 kits?

[@HAMMERPERFORMANCE]

For just the basic conversion there is no problem at all. We feel that the stock crank will support up to 120hp at the wheel and be ok as long as you are not drag racing it. Now, keep in mind anything can happen. If you are a very aggressive rider than we would suggest maybe doing something to address the bottom end just to help with reliability

[@planejoxcrazyhorse7486]

[@royswing5024]

The easiest way I’ve found to get tdc on compression stroke, at least very close is lightly put a piece of Kleenex, tissue, in the spark plug hole and it will pop it out when it gets to tdc, then you can get it exact from there

[@HAMMERPERFORMANCE]

good Idea!

[@royswing5024]

HAMMER PERFORMANCE of coarse in the case of a broken, bent, stuck open valve that wouldn’t work cause it would never make any compression.

[@BryanHemedinger]

would you recommend using a thread chaser to clean before installing new bolts?

[@HAMMERPERFORMANCE]

normally not. We try not to at all costs, or you may take the chance of weakening the the threads.

[@dannybam1]

You have to take the exhaust pipes off or the top cylinder head won't come off is that correct thank you??

yes, you will have to remove the exhaust to remove the heads

[@guipedr]

If I disassembly the top end only to access the cylinders in order to change the cylinder rings, which gaskets should I have in hands to replace beyond head cylinder and base cylinder's?

[@HAMMERPERFORMANCE]

rocker boxes as well

[@Luftbubblan]

Is there any other way of removing the rings that hold the piston in place? I noticed you left some parks on the piston, doesn't seem optimal. I tried with some pliers and got the first one off but the other one i had to use a skrevdriver(Ended up leaving a small mark my self).

[@lucasdasilva5631]

The pin on my bike is hanging up after it comes out about an inch and wont come any farther. Cant figure out what Im doing wrong.

[@grimeyhonkyracing3938]

How do you get the rocker arms themselves out on the 07 XL? Mine seem to be stuck can't slide the pins out

[@HAMMERPERFORMANCE]

Sounds like you're probably trying to remove them without first removing the rocker box? If so, that's a really bad idea. You could damage something, and also you're not going to be able to reassemble it anyway without removing the box due to the fact that the lifter will be full of oil and prevent you from putting the rocker back into position. So just do it right and remove the rocker box. The pin will basically fall out at that point.

[@grimeyhonkyracing3938]

@@HAMMERPERFORMANCE I admit im not known for being too bright but both my rocker boxes are off the bike and sitting on a table. My heads are at your shop as i type this. The rocker arms spin freely but i can't get the rocker shafts out or remove the arms from the assembly.

[@bustersophie7502]

what did the valve being stuck open have to do with the piston coming to TDC, I'm kinda lost on that one

[@Ricky-mouser]

I've been looking at that too. It looks to me like the intake and exhaust are timed together but they aren't timed correctly to the crank. It would be interesting to see the cam chest off and see if the timing marks line up. Here's a guess .... someone put the cams in wrong and when they went to start it the back cylinder fired forcing the front piston up on an open valve?

[@daveg1208]

A few questions: How similar are the Buell and Sportster lower ends? And are there limitations as to how many miles can be on a bike lower end for a safe upgrade to the 1250 - 1275 kits? Thank you in advance. God bless you brother.

[@HAMMERPERFORMANCE]

Through the 2002 model year, Buells and XL's shared the same crankcase. Buell flywheels were lighter than XL flywheels however, for all but the S2 models. But all the parts interchanged including the cams. Beginning with the 2003 Buell XB, Buells got a different crankcase and interchangeability almost completely went away. Then in 2008, there was another big change in the XB lower end, diverging it from the Sportsters even more - except the new for 2008 XR1200, which shared many of the new XB pieces.

[@HAMMERPERFORMANCE]

As far as miles go, it's really the luck of the draw. I've seen cranks fail on stock 883's before they've hit 10K miles, and I've seen hot rodded bikes go over 100K miles on the stock lower end. The other big factor, besides luck, is how the bike is ridden. Spend a lot of time at high rpm and the life is shortened and the risk of failure goes up. Ride it normally with only occasional visits to high rpm and they generally last a long long time. Bottom line, we can't nail down a number of miles, there are too many other factors beyond just miles that factor into it.

I cannot seem to find anyone who can answer my question! I’ll bet you will know. I have an ‘84 XLX 61 and want to do a 1200 conversion. Will 1200 heads bolt up?

[@HAMMERPERFORMANCE]

The 1200 didn't come out until 1988. All 1200's are Evolution motors. Your bike is an Ironhead. There are massive differences in the top ends between Evolutions and Ironheads and basically nothing interchanges. Everything you can imagine is different between the two, including the bolt pattern.

[@brotherjason8635]

Great videos Love if you could make a video how to remove engine from buell x1 👍😁😎

[@HAMMERPERFORMANCE]

You don't so much remove the engine, as you remove the frame/forks/front wheel assembly. Support the bottom of the engine, disconnect the things that connect the frame to the engine/rear wheel assembly, and roll the frame and front wheel assembly away like a wheelbarrow, leaving the engine/swingarm/rear wheel assembly as shown in the video. It's not hard to do.

So between that fact that don't really have the money for a big bore kit right now and the fact that this is my first bike since my dirt bike in my teen years, I felt its probably better to jist fix the leaks and get better/more comfortable on the bike before almost doubling the power output of it ha
