    slt750 fix

    Ive gone through fuel system competely. Replaced tank pick ups,added relief valve for tank all new fuel lines.old ones were deteriated. added fuel filter dint have one. water seperator didnt have one. installed a jet & hose barb fiittng as restrictor , it dint have one. Ive rebuilt the carbs & added a 3 outlet mikuni pump. While I was in carbs the mag & center carbs werent bad just dirty,but the pto carb had a stuck neele valve & some one had tried to remove the pilot jet & failed miserably it was all chewed up, So seeing that fuel fuel system was so bad. Should I index the crank, that subject seems to be asked of me quite often.
    One thing I forgot is previous owner had fuel in going to return side & had return going to fuel in on the rail Thanks Brian

    A basic crank index check only takes a few minutes to do.

    Info and how to are available in the Tech threads, just search for crank index.

    It wouldn't hurt to check.

    I'd check it as well, better safe than sorry.

    At first I thought I would just run it, Assuming that the fuel sys. alone caused the hole in piston! But after further consideration such as cost of piston & rings & top end gasket & any other incidentals. So I am going to index the crank & eliminate all posabelitys. Because I only want to do this once & correct the first time.Thanks you guys are usually very helpful

    You can check the index while the engine is inside the hull. Only takes a couple minutes to do so.

    No reason you shouldn't.

    Indexing

    I have used the search & came up with two methods ! One option was to use a dial indicator & take tdc readings. the other method was take engine out & use degree wheel. somewhat labor intensive! Ive decided to go with #1 My dads a machinist for a living & he deals all day with measuring instruments & tolerannces Ill ask him to help & hell agree then he will break out all these devices want to get very technical.Do you have another method you can share?
    Thanks Brian

    Method #3 Bring any cylinder to TDC the other two should measure the same. The pencil method. If you suspect it to be out after the redneck check then measure with something more accurate.

    Measuring the piston distances with each piston at TDC is straightforward to do.

    Sounds like you father would be able to it with his eyes closed.

    Nothing wrong with learning technical stuff

    It often comes in useful later on

    I like this method, Ill try to acheive the goal without his help , I simply dont want to hear his problems with P.W.C.s he thinks thiere a a waste of time & more importantly a big waste money
    as always thanks for the support help
