    rebuilding my 83 GS750e motor

    Hi everyone. I decided to rebuild my motor over the winter. bought a new to me head and had a valve job done new seals had the valve guides checked, this is in tip top shape! When I split the cases I found that I needed to buy a new crank because mine was so grooved up the machine shop said I couldnt regrind it and get bearings to fit. Anyway I got an excellent crank for only $50 (L11-12R)---ABAAAA. My machine shop gingerly polished it up. I'm very pleased with it. My question is about the oil jets in the transmission journals, I boggered the end up on the one with the smaller holes (left side) At the time they appeared to be the same so I ordered a new one. on further inspection I noticed the holes were different sizes and I had ordered the wrong one. My question is con I put in the new one I bought in place of the one I messed up or will it affect oil pressure or something? If the answer is no I cant then what about reusing the one with the boggered end? When I say boggered up I mean nothing is messed up below the oring, I just broke an ear off trying to get it out. I replaced all the orings in all the jets, even the 4 that are on the main journals. every one of my jets were clogged up by the way! Anyway, If someone could give me advice on my oil jet problem I sure would appricate it. Thanks, Helmut. PS. Im taking lots of pictures of my build and will post soon

    I'm not exactly following you about ears on the oil jets but whatever, I'd get the proper parts.

    Oh, and just a reminder that OEM gaskets are best.

      When I say ear I mean that the jet is slotted on top, rather a deep slot and one side got broken off due to me prying on it. (I should have used a easyout) But like I said, nothing is wrong with it below the oring. how do I post a picture along with my reply???

          This site http://www.alpha-sports.com/suzuki_parts.htm seems to have the best break down of parts and if you navigate to the crankcase page for your bike you will see that there are 3 different jets available depending on the location.
