    Ok, there's benefits to both... but you have to realistically assess the situation.

    Rebuild
    + You get to work on your own engine which is a rewarding experience!
    + You know exactly how your engine is performing and all work is done properly as you did it (in theory)
    + A full rebuild should ensure plenty of life from the engine
    - It's gonna be very time consuming if you do it properly, and given we're coming up towards summer rapidly do you want to be off the road?
    - Some parts are nigh on impossible to get!
    - The cost of a total rebuild may easily reach over $500.

    Replace
    + Quick and easy to swap and engine over especially if its the same model, otherwise a bit of messing around with mounting and conversion.
    + Should'nt cost you more than ~$600-800 for the motor & carbs.
    - You get a new engine and drop it in... where'd the engine come from, whats wrong with it, has it been abused? You just don't know.
    - Without being able to hear an engine running, i'd never sink large amounts of money into it. If it comes with a warraty of sorts it makes it a bit better.

    When i came down to it, i voted for a replace as your more likely to be able to quickly and easily swap the engine over than you are to do a full tear down and rebuild.

    Think closer to $800+
    I didn't rebuild mine persay, but freshened it up. Not including the 6-speed, I spent well over $500.

    Awee... and there was me thinking of picking up a YZF750 6-speed just for the fun of it. Nah, i think i'll save my pennies for the upgrade machine (although it'll still be an EXUP'd, Deltaboxed, Yamaha...).

    I took the motor out and took it to a friend who did it for me for a deal. Of course I had to buy all the barts, he just did the work (and the some more to the cams and valves).

    I'm quite happy with the pennies that I spent. I can go another 2-3 years before I'll need to upgrade. Not saying that I'll wait that long.......

    <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: --> thanks guys for your input i think the 100% result on the poll is what really got me... <!-- s:cool: --><img src="{SMILIES_PATH}/icon_cool.gif" alt=":cool:" title="Cool" /><!-- s:cool: --> so this is where i'm at, I have stumbled across a 3ln3 with 21ks that had its frame bent so they threw away the frame the tank and all the fairings but one everything else is there and i mean everything , this i got for $700.. I was sold when he showed me the remaining fairing. It was the front mud guard which by total coincedence <!-- s:shock: --><img src="{SMILIES_PATH}/icon_eek.gif" alt=":shock:" title="Shocked" /><!-- s:shock: --> is the only fairing i was yet to replace after the rivets came lose and the tyre wore a hole through on a day trip up tamborine and out through the hinterland. the bloody thing was even the same colour as aussie <!-- s:cool: --><img src="{SMILIES_PATH}/icon_cool.gif" alt=":cool:" title="Cool" /><!-- s:cool: -->
    so thats where i'm at <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D -->
    tips on an easier engine swap are welcomed <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->

    Inazuma_x has swapped his engine out not that long ago. Perhaps a PM shot his way would be in order?

    That bike looks excellent.

    My engine shat itself too and I have recently found out what happened.

    (look for my decision time post)

    With perfect hindsight, I should of let the mechanic do his job. I was rather sketchy at the time (paranoid etc - don't ask)
