  1. Thanks for everyones input!

    History of the bike is farely unknown. Last owner (around 55 year old man) bought the bike from Germany somewhere in the early 2000’s. He drove it as a daily ride until he put in to barn around 10 years ago. He said that he drove it to the barn. It was a real mess outyside and I predicted it would be the same inside the motor as well.

    Well when I bought it last fall, I cleaned the carbs, bought new coils and put new gasoline to get it running. I think it ran with 3 cylinders only. When  I dismantled the head, nr. 3 cylinder was ”wet”. I think it didn’t fire...

    I looked at the valves and think they haven’t touched pistons. It’s only a trick of light.

    This is my first engine overhaul so help is appreciated :) 

    If I’d buy a second hand head and  for exampple SPS JR3 cams, can I be using valves etc. From my old head given that they are ok?

    Thanks for all!

    Done the swap on my EFE...no probs were encountered.

    Specifically from what gsx 750 bike model is the oil pump gear from? Gsx 750 ES?

    Done it on a GS1000, plan to do it on my EFE when i get to doing the engine.

    Got the parts so will eventually have a definitive answer.

    It's a few years back but the downpipes, collector and CNC milled alloy flanges were about £450 quid. In all, a bespoke stainless system for the bike was about £650, which is less than many fancy 'branded' systems, which wouldn't fit properly without modification/bodgery. Dave's pipes mimic the old Harris systems and use large bore pipe rather than the weedy looking 38mm stuff. Here are some pics.

    That looks nice! I will think about this one.

    For a great quality, cost-effective stainless exhaust try Dave at Exhaustcraft in Cumbria. He can make you a set of pipes and then post to you. He doesn't need the bike unless there is a very good reason. He did my downpipes and collector, and I had a silencer made locally to my spec.

    Hmmm. Interesting.. What did you pay for the set?

    Welcome to OSS!

    Delkevic is making exhaust for GSX 1100 E, Black Widow Bandit 1200 exhaust will fit with some modifications & spigots as well as Delkevic Badit 1200 exhaust.

    I have Delkevic Bandit 1200 down pipes on my 1984 GSX 1100 EFE. Mid pipe and muffler are home made. 

    Thanks. That is one option i have looked at. The best would be the bolt on way to go, but I have learned that there are not many options for it :S

    i really like the look of Marving race system but the decibel level of the exhaust excees finnish levels. I think the level is 103db.

  7. Hello to you all oss members!

    In a nutshell:

    Salvaged this ugly, left to die bastard from a Finnish barn last summer and been customising it since then :DIdea is to customise a sporty daily ride which I can ride also in motorways (will keep the Police academy front fairing). I have upgraded Hayabusa Gen1 rear and front end to the bike. Everything has now been stripped and sent to powder. Next thing in the list is the engine check.
     

    Question to you gentlemen is what kind of decent priced bolt on sport exhaust systems there is available? What kind of solutions do you all have? I know tha Marving does 2 kind of systems and Vance&Hines sidewinder is not for me :D

    Thanks for advance!
