Project SMX

  • @calum Thanks bud, I have a vision and lots of shiny new parts already waiting to go back on, once I've got the frame and wheels sorted, it's smaller bills from there on mostly - well hopefully.

    The previous owner had a lot of work done to the engine. It's running a Mitaka head and has had a rebore, but there's a serious oil leak at the back of the engine. So I think I'll have to play it safe and strip the engine down and start over? Sadly that will add lots of time and more expense, so this build is most likely gonna take me into 2019 now!!! 😞

  • @ninja The Mitaka kit is the cheaper replacement pattern part of the market.

    I did have both Mitaka and original Gilardoni Barrel and the casting is night and day between the two. The OEM is far superior.

    What that means in real world performance will most likely be negligible and there is no reason why the Mitaka barrels cannot be reworked.

    The oil leak coming from the gearbox or the RAVE. Pretty common to see them out the RAVE. A new gasket would sort that out.

    Although given these engines proven performance, and ergo, reliability. I'd recommend an inspection and the minimum. If the engine is out, seriously do at least the minimum.

    Main bearings (not special bearings like the DTR so these are cheap for Koyo's) £20 and the primary gears (£30). They are the usual culprits.

    I'd inspect the crank for play. I recently "rebuilt" crank I acquired out an MX engine I got had zero play in the crank. Good, but literally, had zero play in the crank (bad). There should be some float. So this crank will need rebuilding.

  • @calum I'll take some close up pics of the engine in the morning, there's oil all under the carb area, around the rear shock & spring is covered in oil and black gunk. 😞

    I will most likely see what funds allow, but maybe a full bottom end rebuild whilst the engine is out would be prudent. And then when I've sold a kidney may be a 140cc kit , Zeeltronic, 34mm Delli, Carbon reeds, Scalvini exhaust, new power valve, etc. etc. 😉

  • @ninja if it's black sticky oil then it sounds like two stroke.

    Most of that won't be necessary, but you will want to examine the state of the engine.



    She needs a bit more work, but she's getting there. 🙂

    Anyone have any polishing tips???

  • @NINJA Buy new.

  • @NINJA yeah get someone else to do it 😂

  • @Minia This swing arm is brand new, I got it off a dude in Finland for a bargain £100 delivered. The originals are anodised, so I have stripped that off and sanded it down to bare metal. Then I've rubbed it down with wet n' dry, decreasing in grade and finally hand polished it. It still needs some work as I have stated, but she's very shiny compared to what she was originally. 😊

  • The Aprilia metal is quality, shines up nicely.

  • I sold my spare Rotax 123 engine, 34mm Dellorto carb and an Arrow exhaust the other night. So there's some funds for new parts, this sexy beast arrived today;
