just about to start upper end build 850

[gearhead13]

I use a three shoe hone when I want to hone/deglaze, works fine for me. Its much cheaper, available locally and adjusts itself for most any size bore.
Its a roller bearing crank, so getting oil to the mains and rods isnt critical, as long as the cams were properly prelubed. I use Cam lube very sparingly on my cam lobes and followers every time I disturb them.

its true, when i worked for Honda you could tell how a new owner "broke" his engine in. 2 identical bikes, 1 would go like hell, the other wouldn't pull the foreskin off a snail.
1st bike,the owner took it straight from the showroom and rode it how it should be ridden.
2nd bike, the owner "carefully" ran it in, not putting the engine under load and not revving it too high.

usually bike No.2 could be saved to a degree by thrashing it up the road when it came in for its 1st service. (usually to the owners disgust, but they did have a wry smile on their face after, when they feel how much better the bike rides)

Keep this in mind as well. Basically, run it like hell after the rebuild

No you can't just scotchbrite. Get a ball hone or pay someone to hone the cylinder for you.

There is a reason why all the pros use the ball hone. Think about it.

i looked ay my jug today...itys damn near perfect....not a ridge or anything in sight...could i get a scotchbrite pad an wd40 an just clean them up real good? i cant find a ball hone local and really cant afford to buy it an use it once

Start calling around to local mechanics or machine shops - I got lucky. After the 10th "no go", I got a machine shop who referred me to a professional motocross mechanic - he only charge me $10 a cylinder!

Personally, the cylinders are one area I don't dare touch myself. Too much potential for serious damage. If possible replace pistons rings too!

Basically I lucked out, but I believe local "Twisted Cycles" shops charge $20 per cylinder. So, 40-80 for a full 4 cyl, or 40 to hone em yourself and potentially make mistakes (like I so often do!)

Good luck, I'll be rebuilding my own 850 once I finish this 1000 =]

Edit:

Once thing you definitely want to do once they're honed is take a rag and some oil - I used wd40 actually - and wiped down your cylinders very carefully. This will remove dust and debris leftover from honing. Also, since you very likely have cast iron sleeve it will prevent some rusting before you get around to reassembly.

[koolaid_kid]

If you used Water Displacement 40 (WD40) to clean it you are not done. You need to wipe it down with some sort of alcohol-based solvent to clean the WD40 residue off, then you need to wipe each cylinder down with some type of oil to prevent rust. Motor oil is readily available and does a fine job.

what size grit of hone do i need, im just gonna buy one since no one within a 50 mile radius has one...ive used them before, just didnt wanna pay 40 bucks for something i probably wont ever use again

[chef1366]

I use the 320 grit.

I use the 320 grit.

3 inch size right?

3 inch size right?

If you are doing your 850, and it has not been bored out beyond stock, it is a 69 mm bore, which is 2.717 inches.
I would not use a 3 inch ball honen on it, there might be too much pressure on the walls.
Even a 2 3/4 inch hone might be too much, I am not sure.

You really want to wash the cylinders with hot soapy water and a nylon bore brush after using the ball hone. After drying, if a white cloth comes out clean then lubricate them with some clean oil. If not, keep washing them until they are clean.

well crap...its not been bored..i think i was the first one to pull it apart...i cant belive its so stinkin hard to track down a hone, and find the right size...this hone ordeal has set me back already..

[Nessism]

70mm seems like the right size.

I'd get this one...http://www.enginehones.com/234240sc.html

It's 240 grit, but that's fine for a used cylinder.

thanks ill get one ordered...

also i know most you guys say use oem...z1 has the valve seals for over half the price of oem...are they just as good?...i under estimated the cost of doing this motor by about 150 bucks
