Hi guys thought id see if yous had an opinion on my prediciment, my project zx7r P1 is coming along nicely and I'm up to the engine which I can go a few ways with, I am thinking of rebuilding my original engine myself using the Haynes and clymer manuals as guides, I'm not a mechanic and never done anything so involved so not overly confident but still would like to give it a go. I was also thinking of using the wiseco 779cc piston kit any one ever used these or have an opinion?, I have been quoted maybe upto $3000 for a mechanic to rebuild and that's above my budget so I was thinking I would do everything except the head ( leave that to the mechanic) but after quoting all the parts I need eg main bearings, pistons, gaskets etc its right up there also, is there a rebuild kit i can get from the states or something?? i was going to order majority of the parts from mrcycles.com. So my main point in posting this is to get opinions on whether I should just rebuild it myself, have the mechanic do it, or buy a second hand engine?? Also with a second hand engine what would I expect to pay for a good condition engine, best place to source one ( I'm located on the central coast NSW).

I currently have 2 engines both I have disassembled and if rebuilding myself would be the better option I do have a few mates that are car mechanics that are willing to give me a hand.

IMHO and with my experiences (limited) with bikes, it's probably better to get a decent second hand motor or get it built by a reputable motorbike engine builder, rather than attempting it yourself if you're not experienced with engine building. Tolerances required are not like cars  and the fact that these motors spin >10k RPM could have a grenade on your hands if something isn't quite right in the build.
