that is my workshop NAR Newmarket Auto Repairs i have opened up the shop a few times on a friday night to do some rebuilds so guys can learn and show other what they know. Doing a full rebuild would take a little time more than a friday night bqq and drinks. i can price up arts for you if you want and coul look at doing for you how far a rebuild do you want to do ???

right deal is.. hopefully getting a bike which wont turn over, kick start jammed. the guy says the big end had enough play to let a sproket move and jam.. sooooooo. he seems to think that a bottom end rebuild will do. (how true this is im not sure, what do you think?)

in terms of how far id like to go with the rebuild.. i think probily a full bottom end. so big ends, conrod (not sure if its somthing i need to do), check the valves maybe get a kit with new intake ones? piston, rings and gaskets. if ive missed anything let me know.. this will be my first time trying something like this but i do have a couple of clues.

i went on motocrossparts.co.nz and figured parts will probily cost about a grand. am i far off??

crank bearing $22 out a stock at the mo
piston about $350
full gasket set $300
would have to check $$ on conrod kit not listed on line

these are rrp would do them at a better price than shown here by a reasonable amount
personable i would strip it down slowly lookin to see what has gone wrong unless it is already stripped in which case you need to hope its all there and check every thing as you go

Actually, check the pricing on a hot crank kit and just replace it instead of replacing the conrod.

yea that would be awesome if it was just that and it was a cheap repair.. what do you guys think the chances of cracked engine are? or this being serious serious. i guess its hard to know not knowing the bikes history etc?

what type of piston.. is it forged can you get a not forged for motox bikes? i was looking at the JE forged piston kits?

right sounds like a good plan to strip down slowly.. and just replace what needs to be replaced?

genuine kawasaki piston kits are only $280, (remember 05 rmz's are kawi's)

the cost will depending on what you want to do, it may be cheaper to buy a crank than to get it rebuilt depending on cost, i would stay away from the aftermarket cranks as we have had a few problems with them,

pm me with exactly what you are after and i can quote parts and labour if you need,

mainly had it with 2 stroke cranks, have been to scared to put it in the four strokes, less than 5 hours with 2 kx85 cranks, hot rods from memory, out of china, and less than 2 hours on a 250 2t as well,

not sure what casued the problem, suspect it was not enough oil flow and then caused heat, either by lack of slots in conrod (pro x rods had this problems on KX85's and 125's for a while) or they are pressed together to tight,

I put a prox rod kit in my ktm seems ok so far only 40 somthing hours though had herd at the time I did it the bearing they use isn't as good quality and the genuine one , the rod itself looked identincal though.

Gasket sets and rod kits for your bike can be had for slightly less than 130usd each plus post from the states .

It cost around 100 bucks to get my crank rebuilt and a couple of stuborn bearings pressed out by spectum.

280 for the genuine piston from scott sounds pretty good hard to do better than what the factory intended

Definitly best to pull it down before you start buying parts though.
Engines really arn't that hard to work on as long as you have a manual ,the money you would spend on labour for somone else to do it will pay for most of the tools you will need if you don't already have them.
