155z or yx160 install

id say that might be for doing hydraulic rams or similar type work...it gets fitted into an overhead hone machine..and it doesnt appear to be adjustable

Okay so honoing. Does it take off anything from the cylindar walls? I now know that it makes a "crosshatch patern" whiched is for keeping the cylindar walls lubricated properly? Is a ball hone better than the one in the link? Whats the better degree 45, 50 or 60? Or doesn't that mater?

Sorry for hi-jacking your thread.

Is that a good hone?

thanks lads i will have a hunt for the parts, i spoke to a lawnmower shop and he will charge 150 labour if i get the parts and take the engine off the frame and take in to him, does that sound reasonable

Honing a new cylinder in a crosshatch pattern allows the Rings to seal alot better .

And i believe it takes off a little material each time.

$50 for oil? more like $10

$150 is way too much for someone else to re-build it with you supplying parts, you should just do it yourself and pay someone like $25 to hone it for ya, shouldn't cost you more than $150 to do a top end rebuild including parts

where are you from mate, let us know and maybe we can point you to the right place. or maybe someone here is keen for a bit of drinking money

i am from traralgon in victoria that would be good thanks for the help lads

hi i recently brought a new crf70 and now im looking to put a new motor in it as big bore kits for 70s seem way to expensive for what you get. iv been looking at getting a 155z crate motor for it because iv heard good things about these motors but are they really any good? and how easy would one fit in? or should i go with another option. any info would be appreciated

mate.... WHY??? you've got a crf 70 and you wanna put a chinese engine in it? pure insanity. If you want a 155z you should sell the 70 and get a pitster pro.

yer, please dont put a china motor in it, if you want a crf70 mod you should have thought of the expenses, other wise brought a china, a honda 70 build wont be cheap
