120+ HP Sportster? You guys are crazy. I just bought a used 883 that somebody did the 1200 kit and some Screaming Eagle whatever, and it's fast, fast enough for me. I know it's nowhere near 120 HP though. I do start sliding off the seat and the front wheel is beginning to come off the ground, so that's fast enough for me. It's a Sportster for sure. Enough for me.
why do you guys run the rods backwards? didn't they do that on old UL flatheads? I always thought that the female rod went on the back to fling oil onto the front cylinder? does that change the balance percentage?
The correct crankshaft position is when the mark on the pinion gear is pointing straight toward the middle of the number two cam. Neither piston will be at TDC when you've positioned the crank this way.
So how reliable is this as a daily driver? I’m new to building as I’ve always been a sports bike guy but now am building out a 98 xl1200 sport and want more power but also reliability that I can ride across the country on with no overheating issues or anything like that
recently did this to my 2000-2002 buell engine. My big question is I need to replace the detent plate snap ring. When I go to put shift star back on shift drum the star does not go flush. Installing star when its in neutral. Is it common to have an angle on shift star once putting it back on shift drum. Thank you.
4 drops (3-6-9-and 12 oclock) of superglue on the seal, pushrod cover upside down on a felt protected vice and push the oiled pushrod tube down on to the seal with a piece of wood and a mallet. Make sure you align the pushrod tube perfectly. If you don’t use the superglue the seal pops out even if you have every part dry. If you use a bead of super glue on the seal, it doesn’t allow the seal to spread enough. We are talking 1000’s of an inch to make or break it.
Hay man I have a problem....I put on new screaming eagle heads on my 2012 Harley-Davidson sportster 72 1200 custom. And now oil is coming out from the rocker boxes and in to my intake in to my air filter. I don't understand it.....I've been through it about 6 time or more😢
Gearing is a matter of personal preference and what's most important to the rider. Some guys are more into highway riding, so they may gear taller. Others value acceleration most, so they may gear shorter. We don't make a recommendation one way or the other. We do however provide information on readily available gearing options: www.hammerperf.com/883conversions.shtml#faq9 . Also I can tell you that the vast, vast majority of 883 to 1250/1275 conversions are done without a gearing change.
Watch the video several times and then read the procedure in the HD Service Manual. I barreled in, over compressed and broke my pressure plate. Dan was a HUGE help getting me out of the mess and gave me a fantastic web site for buying HD parts. I do have some tips to share. First, I did not replace the oil seal around the shifter pole. So when I tried putting the primary cover back on I kept knocking the gasket off. I finally put the gasket onto the primary cover and dropped the dowels into the cover as well. Then I ran a small zip tie through each dowel which let me push the primary cover over the oil seal while pushing the primary chain behind the cover. Once aligned I cut the zip ties and secured the cover with screws. The service manual clearly indicates which screw are long and which are short. Second, the O-ring behind the clutch inspection cover kept falling out of place as I tried to put the cover on. I used four little dabs of sticky red boat trailer axel grease to hold the O-ring in place and the cover went on without a hitch. Thanks Dan for the video and the help. BTW - the Hurricane Air Cleaner I bought from you folks years ago in Colorado is still working just great!
enjoying the vid. Still learning on the Sportster, but I know when doing this job on a big twin, the engine sprocket nut should not be done with impact as the jarring can knock the magnets loose and break your alternator (working on one now like that)
Do I understand correctly that the reason you cut down the cam cover to bare minimum was to allow easier access to the oil pump? In particular, to allow the oil hoses to be connected after the cam cover is installed?
Question. Mine is going in neutral from 1st to second until I let off the throttle a little bit. I was going to service that shaft (due to a video I found), but mine is different. It’s a straight shaft. It’s not made like this one.
My pump’s inner gear cracked and must’ve been hard to turn causing the brass drive gear to shred slivers all over and down into the pump. How come they don’t put a metal screen over the pumps return hole?
I opened up a 07 XB9R and the oil pump gears were stripped and metal went into the pump and seized it up. The large pump gear was cracked and it didn’t have the spacer plate. Maybe the missing plate caused the pump to swell and crack then the drive gears stripped. My question is why is there no metal screen over the intake hole to keep metal out of the pump in case those drive gears shred off ?
Can the cams from a 2007 xb9r go into a 2004 883 block. I noticed the number 2 cam is on the right side of the oil pump. On 883 it’s on the left. Number one is in the front and number 4 is in the rear.
