Torque spec's top end sportster - XLH Sportster 883 Harley Davidson Motorcycles

SOURCE: primary torque specs?

use a 3/8 ratchet with the torx bit and rest a little pressure on it and you fine Do not over tighten no not use loctie even and snug

SOURCE: Need cylinder and cylinder head torque specifications 98 XR 250

you dont need torque specs on that just use a 1/2 inch drive with you 14mm or16mm socket hold the wratchet right at the top and tighten it as tight as you could get it like that then use wratchet in normal position and just give it a little snugg it will be perfect i have done it a million time on the same type of bikes...

SOURCE: I need torque specs for top end cylinder heads for

its located in the manual. you really should have one if you want to do job operations at this level

SOURCE: Top end repair: After all is removed and replaced,

You will want to install the piston onto the crank before you install the cylinder and head. With the head and cylinder off, the crank rod will be exposed. Put some shop towels around the crank rod before you start to avoid dropping any small parts into your lower end while you replace the piston. Your new piston kit should come with: (1) piston, (2) circlips,(1) wrist pin and (1 or 2) rings depending on the bike. Also it is suggested that you should replace the wrist pin bearing as well (usually sold seperately). If you have not removed the existing piston you will need to remove one of the circlips from the side of the piston. Do this by using a small screwdriver in the teardrop hole where the wristpin attaches the piston to the crank. Then push the wristpin through the piston from the side that still has a circlip through the side that it has been removed from. Once the wristpin is out, the piston will pull straight up off the crank and the wristpin bearing will slide out of the crank rod. Before installing your new parts you will want to have some 2-Stroke oil on hand. Lube up the wrist pin bearing with 2-stroke oil and slide it into the crank rod. Install ONE of the circlips into the piston before connecting it to the bike. Do this in a clean area because these things like to jump out when you're trying to put them in. BE SURE IT SEATS FULLY INTO ITS GROOVE. Once ONE circlip is in, slide the piston over the crank rod WITH THE ARROW ON THE TOP OF THE PISTON FACING THE EXHAUST!! so the wrist pin hole lines up with the wrist pin bearings. Lube the wrist pin and slide it into the piston from the side with out the circlip, through the wrist pin bearing until it seats against the circlip installed on the opposite side. Install the second circlip and MAKE SURE IT SEATS FULLY INTO ITS GROOVE. Install the rings onto the piston. (Some OEM rings have a flat side and a sloped side be sure to match the piston you have removed) Notice that there are tiny notches in the rings that must line up with nipples in the ring seats. This is the only way the cylinder will slide on properly. Next, put a thin coat of oil on the cylinder walls, remove the shop towels, and put on the cylinder base gasket. Now, with one hand, pinch the rings tight to the ring seats making sure the nipples in the ring seats sit in the notches of the rings. With the other hand, slide the cylinder over the piston. THIS SHOULD SLIDE DOWN EASILY! If not, remove the cylinder, verify the rings are properly seating in the ring seats and try again. Once the cylinder is on install the base nuts. If you can get a torque wrench on the cylinder base nuts tighten down to manufacture spec's (24 ft lbs) Usually you can not get a torque wrench on the base nuts because the cylinder walls are in the way so I give it a german torque "goot-n-tite" (good and tight). Next put the head gasket on and the head gasket, and tighten down finger tight. Do this in a criss cross pattern, starting off with hand tight, then 3 or 4 steps until reaching the manufacture spec (18 ft.lbs). Put the plug in and you should be ready to go. Be sure to break in properly by running 3 heat cycles through the enging. From fully cooled, start the bike and ride it using NO MORE THAN 1/2 throttle until it reaches full temp. keeping the RPM's varying. Let cool COMPLETELY. Second heat cycle, same thing except use up to 3/4 throttle. Cool COMPLETLY AGAIN. Third heat cycle ride up to full throttle. Be sure to keep the RPM's varying in all heat cycles. No long runs at the same RPM level. Here is where I got the specs for the cylinder and head torque settings so you may want to call a local shop and verify. http://www.thumpertalk.com/forum/archive/index.php/t-764174.html
