05.Banshee.SE Posted April 15, 2009 Report Posted April 15, 2009 I'm about to put my first top end back together...any tips and stuff I should look for? Quote
shee4speed Posted April 15, 2009 Report Posted April 15, 2009 Just put it back together like the book says. :thumbsup: make sure the pistons are facing the right way,circlips are in properly,gaskets correct,and everything torqued properly. Quote
05.Banshee.SE Posted April 16, 2009 Author Report Posted April 16, 2009 What do you actually lubricate and what with? I think I remember hearing something about putting some oil on something somewhere in the process. Quote
05.Banshee.SE Posted April 16, 2009 Author Report Posted April 16, 2009 EDIT - What's the best break in procedure also? Quote
bbcmudtruck Posted April 16, 2009 Report Posted April 16, 2009 Lube the cylinder walls and pistons with your premix before you put them together. Also put a towel down around your crank to prevent the circlips from falling down there in case you drop one while installing it. Once assembled, do a couple of heat cycles and retorque the head and cylinder bolts. Run her easy for a half tank or so and do a plug check. If the jetting is good, let her rip! Quote

Wow, that's simple enough. That's exactly what I was looking for. Thanks, sir. Quote
fastrthnu Posted April 16, 2009 Report Posted April 16, 2009 Also I dont know if your guy did it or not, but usually you have to give em a bath to wash out hone jism in hot soapy water. re lube immidiatly!! then make sure your rods play is good (within spec). Then make sure you wrist pin bearings are iight. Then check your piston to cyl clearances. Altough you have a good builder, your retarded if you dont check this because in rare cases,... it wrong. HUmans make mistakes sometimes. Then you need to check the piston ring gap. Put it square in the cylinder about an inch down all the way around (square) and stick yer feeler gauge in there with all 4 in both cyls to see they are within spec. this may not haven even been checked. if you want to check squish/head clearance,. you can stick a pc of solder in there, bolt the head down and turn it a little so the piston doesnt travel enough to scissor that between a port and piston or fall out all together,. then pull the head and measure how much you have with calipers since it will smash it to the gapped size.... and stuff....

NitroTate Posted April 16, 2009 Report Posted April 16, 2009 Just take your time and pay close attention to the details of what the manual says, it's easy to miss things. Kind of like the old saying, "measure twice and cut once" well, "read twice and assemble once". Good luck and have fun with it don't rush! :biggrin: Quote
pinkshee Posted April 17, 2009 Report Posted April 17, 2009 make sure your rings are on the right way. i learned the $200 way Quote
2001Stroker Posted April 17, 2009 Report Posted April 17, 2009 Also, make sure the ends of your circlips spun around, away from the hole. Keeps it from popping out, and grinding on the cylinder wall. Quote
