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.

Zx7r P1 engine decisions????? (Gog975)

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.
