    Since I got the Bike the Flywheel Casing has been loose,
    today I noticed 1 bolt was missing underneath so I replaced that,
    seemed secure then when trying to wiggle it with my Hand,
    (where as before it would move)....
    I started the Bike and due to the vibrations I noticed another bolt completely out but still 'there' as the thick water pipes were there so the bolt couldn't drop out, there was no way for me to get to it with an allenkey, I took 1 of the pipes off, loads of antifreeze water over my hands lol... but still couldnt get to it, I managed to push the bolt back into the casing (not tightened) and left it like that as I wanted to go for a ride before the rain started and as it was out since buying the Bike I didnt think it would matter (until I can get to it another day to tighten it),
    went for a ride and noticed a weird sound which wasnt there before,
    I cant even explain it, it just isn't right and sounds like its coming from inside the casing,
    I havent taken apart anything in that area before and dont want to start unless I know what to expect and so on........
    at that time aswell I noticed the nuts holding the Exhaust onto the Engine part wasnt fully tightened so I undid them and replaced them (I like using new) and tightened them, but now the Exhaust sounds like its blowing/popping more.....

    Any suggestions on what I can do/try?
    will is be simply taking the side plastics off,
    disconnecting the water pipes,
    taking the flywheel/waterpump casing off, slowly,
    and seeing what it's all like and seeing is everything is tight etc?

    did you fill the coolant tank back up after antifreeze came out?

    Just abit weird where as it was the rattling of the loose cover first,
    and that got tightened up but now its a whole new noise :-/
    and trying to get to that other bolt was really pissing me off....
    im not any good with all that side of things, im ok with most but the waterpump etc i've never had to mess with so I dont have a clue about it all.

    Was the pump/cover left loose? The flywheel and water pump impeller has to fit properly, it isn't just three holes/pegs, one peg is off set to the other two, it need's to be right or it will knacker the pump shaft.

    When I got the Bike that Cover was loose, I could easily wobble it with my Hand,
    you could hear it when the Bike was idle aswell (at lights or whatever),

    I noticed a bolt missing underneath which I replaced,
    and then started the Bike and kneeled down by there to double check the rattling had gone,
    and it did... but noticed 1 bolt completely out, but again it cant drop due to the pipes etc being in the way so it just sits 'on' the cover and makes a high pitch rattle but thats not the noise im hearing,

    im pretty sure its inside the cover, but again i've never taken 1 apart so im not sure of the goings on inside there,

    noticed the Exhaust plate doesnt fit flush either, with both nuts tight theres still a gap which I think is making the Exhaust pop/blow (abit annoying now since I last replaced the nuts), will some Exhaust Paste around the gap help at all?

    regarding the covet etc, i'll have to wait until tomorrow in day light and have a good look, will wait until my stepdad gets back from work to help out aswell, will have to remove the waterpipes etc to get to that annoying bolt! he should have some better tools aswell.

    Theres a quick video, abit shakey etc but can see the Bolt that isnt in and the noise THAT makes, but after riding up the street you can hear the other noise alot more... will check it all tomorrow anyway with better tools and go from there.... baring in mind that loose Bolt goes ALL the way back into the casing to the point where you cant actually see it even when it isnt tight, just cant get a tool in there at the moment due to the pipes etc so have to get all that off or a certain tool (stepdad mentioned it but cant remember the name).

    Here is it so far, just taking the plastics off and 2 pipes,
    i've taken the bolt off from underneath which I put in yesterday as it was missing,
    the 1 thats out but 'still there' I still cant get to,
    theres another 2 that I can see which are actually in...

    So what now, undo the remaining bolts and take the other pipe off and then take the whole Cover off? (red part in the photo) to check everything looks ok inside?

    Think it's sorted, stepdad got me some new tools today which helped alot, put the bolt back in underneath, and tightened up the one that was out, other 2 are TIGHT already, no more rattling of the cover, seems solid enough, did notice a weird noise which sounds like its coming inside though, like.. a fast tapping? never noticed it before though so it might of been there previously.

    I really wish I knew someone near me that knew about Bikes lol
    its 1 thing after another, why cant it just work normally!

    Anyone know why this is making this noise?
    I replaced the Starter Motor/Bendix and Front Pulley when I first got the Bike as they were both broken,
    Starter Motor/Bendix wasnt springing back, and some parts were snapped off the Front Pulley,
    both were replaced though, Belt looked new so left it on... had new Rollers aswell but the ones in were basically the same so guessing were not long put in so left them in, but whats causing this noise? its horrible and as you can hear... very loud on that side of the Bike!



    Anyway theres still a weird noise on the Exhaust side,
    talking of the Exhaust, put a Gasket on onto the end of the Pipe, put the end of the Pipe up into the 'Engine', put the Exhaust plate up over the threads, put the nuts on, tightened them up, put Exhaust Paste in the gap... yet the Exhaust still blows/pops when slowing down etc, never had a Scorpion Exhaust before but are they supposed to do that? as you can get some that are supposed to sound like that, theres nothing getting through the end of the pipe/engine....?

    Regarding the Flywheel/WaterPump Cover, again it's all tightened up, but can still hear something which sounds like its coming from inside, what sort of noise would be made if something was wrong? as im not sure whether its just the noise from the other side transferring across...

    Noticed the pipe clips I used are crap aswell, went for a ride then went to my Brothers and revved the Bike so he could hear the noises i've been hearing and water was skirting from 1 of the pipes!!!! just waiting for the Bike to cool down then going to see if the pipe can fit on any more and try another clip, cant tighten um too tight as they just f*ck up!

    Noticed the bottom Bolt keeps coming out, put 1 in and it seemed to thread in ok, but obv due to vibrations its come out :-/ went to put another in (same size as before) and it just slides in and out now so the threads obv f*cked inside....... still not sure what the noise is though, even if I take it apart im not sure what im looking for (fault wise)
