Hi all, well so last week my woes started but oh how they get worse. Firstly i had some problems with my bike (leaking carbies and stalling at lights). So i decide to take my bike to my mates old mechanic (name not being mentioned till i get my bike back tomorrow) to get a service done eg. fix leaking carbies and a service. So i drop it off and wait for 2 days i hear nothing from the shop so i ring them and say whats the prognosis and the damage, i get the bill and pay it off and take my trusty bike home. He does note to me that it requires a different set of plugs (hotter). On my way home i notice its a bit slugish and it sounds funny, so i get home and it sounds like a flat 4 car engine (missing and what not), so i check to see that nothing is disconnected or wired incorrectly. I also check the exhaust and notice that one of the cylinders is not overly hot like the others so something is not right. After about 30 mins i have the bike in pieces and i figure something is wrong so i ring the mechanic and explain the story and he says well like i told you its got the wrong plugs. I think well thats a bit strange cause it was running fine apart from leaking carbs and stalling, but ok i will go and change the plugs. I go and get new plugs, gap them and fit them and i also noticed the leads were stuffed so i go get some leads/coils and put them on. Start it up and what do you know its still the same no difference. I ring the mechanic right away and explain i have done what he asked and i am bring it back cause its not right. So today is crunch day as i rang the mechanic yesterday and he says he is too busy and call back tomorrow. I ring him back today and guess what he cannot fix it, and he also mentions that one of the cylinders has dropped pressure (the one that was colder than the others) eg. somethings farked (either valves, piston rings,conrod or ringland) So i ask well it wasnt like that when i dropped it off so i was not going to pay to fix it, he also noted he was definately not going to pay for it. I said well i am coming to get it and i wanted it back together so i can ride it home. My next step is to get a replacement engine which is not going to be the cheapest option but i figure i dont have much of a choice considering i need transport and enjoy riding. My question to you all is has anyone done this themselves and if so was there anything that was more difficult than a particular step. I feel pretty confident to do it myself as i have worked on race engines and put engines in and taken engines out of cars. Can anyone recommend a wrecker/reconditioner that i could get an engine from. I have got a price for an engine $950 swap over, not including installation from Victorian Motorcycle wreckers in Heidelberg West. Can anyone point me in the direction of what i might need to know for a swift engine change. My plan is to do this over several weekends in my dads garage. I am aware that i need to let vic roads know of the new engine number apart from that anything else that i am missing? Thanks for your help and i hope i get my bike back without any dramas from this clown tomorrow. More details to follow when i get my bike back i will be black balling this bloke to make sure no one else goes through this shite.
