    Picture? 

    Cam chain guide holder, in the center of the crankshaft has 2 of those screws...

    Oilpump might have those screws too, that means, take the clutchbasket off to inspect, Oh I just see that you checked that already..

    The alternator is also held in place with screws if I remember correctly, but the screws might be longer than 25mm, but coming loose and end up in the sump might be a bit far fetched.

     

    Is this acceptable?

    I have seen a lot of race pistons in stroked car engines machined with the oil ring exposed into the wrist pin hole, and they work successfully. It is an oil scraper and does not need to form a seal on the lower ring land. If you do not like them, send them back. On a bike engine I personally would have used a piston with normal ring pack, and spaced the barrel to suit the stroked crank.

    The other 3 pistons are ok.

     

    I'm afraid that when the scraper turns the ends get hooked and scratch the barrel.

    Gents,

     

    I had pistons copied by JE, I'm not impressed by what they did, but hey..

     

    One piston has this, see red arrow. Grooves of piston rings were cut, then the bore for the wrist pin was done. Because of a lack of enough material a bump in the oil ring was created.

    I had to file the bump off to make the oil move in the groove without too much resistance, there for there is a gap were the wrist pin is, about 6mm, the oil ring is not supported.

     

    Is this acceptable? As in, is this going to cause trouble?

     

    One hand I would say, should be right, other hand.... I'm not too sure..

     

    Thanks

    @Reinhoudthanks but I have 1 complete motor and a bottom end spare. In fact I’ll be selling stuff off soon as I need the room. When I get cranks built I use 494  rods. As strong if not stronger than 493

    I haven't heard about 494 rods before, which Suzuki has those?

    Which wrist pins?

    Funnily enough I mentioned this to Sean @ BigCC yesterday in passing and he whipped out a broken pin that had gone on the dyno! It had multiple pulls and was making 542bhp at failure - it was from a 1000cc bike and 15mm dia! Mentioned 18mm GSX -  his words - 'No problem!'

    Haha, thanks!

    Pins are just not a problem until you reach REALLY high loads ie. 40+psi boost, excessive Nitrous or Nitro fuels - be more concerned about the pistons and rods and the oil system to keep THEM alive!

    Ok, thanks.

    Stock or whatever comes with the aftermarket piston you use. At that output you won't be stressing the pins!

    I don't have a clue what they can handle, I'm just afraid it stuffs up again, I can't afford a second time. ;)

    Gents, I'm about to order wrist / gudgeon pins, but I'm afraid  get not the right ones..

     

    What wrist pins do you guys use? 18mm.

    I can find some on the APE site, but they're 5mm too short.

    It's for a GS1000.. I had planned to get pins what goes in the GSX1100.

     

    A max of 200/220 crank HP, just a guesstimate ;)

     

    Any ideas?

     

    Thanks

    Biggest bore on a GS1000 ?

    @FJDif it is a gs1000 8v? Block it will give you roughly 1240cc @ 78mm. Imo it’s on the limit and will have very thin liners. I considered doing this but for my road bike I went with 76mm Kawasaki Pistons from Mtc. Even using gs1100efe liners I had to hand relieve the crank cases. Using any liner that is bigger on the od than a efe liner makes the block very weak and will window out into fresh air between the cylinders, with that you get oil leaks and a very unstable block with which ring life will suffer. 

    It's deffenitly on the limit, but it does work alright.

    So block arrived, must be 78.0 bores as my dials show, will get them measuted more accurate and start finding some pistons and rings.

    Anyone has some Wiseco, MTC or JE part numbers i can feed google with ?

    There are not really partnumbers for.. 

    Send out emails to those companies to get some quotes.
