On a 155z with a TB hicomp piston what OKO 26mm jets will i need?

 

[my67xr]

if you are ordering the OKO from DHZ, they might even fit the jets for you, so it's all ready to go

i have read in a few other posts here,
if you tell them what mods are done to your motor/bike etc, they'll advise on what jets they'd recomend, and fit them for you

^^^^. Spot on! That's exactly what they do!

What do i need to torque my head bolts to on my 155z?

 

[timeeh]

20nm should get you out of trouble

In what order do the tb piston rings go in?

Just split the rings and there's two of the left and middle ring. Do i need to hone the cylinder?, what tools would i need for that?

 

[timeeh]

have a look here, it may help you a little?

also with your rings the 2 smallest and 1 wavy rings sit in the bottom channel, then the darker of the 2 rings left goes in the middle then the last one in the top. Skip to #11 (in the above link)for a more detailed write up.

As for honing, not a bad idea if replacing the piston. You will need a honing tool

or take the barrell to the local bike shop.

Is honing necessary?, also in the bottom channel what order do the 3 rings go in? Thanks for the help

with the oil rings(2 thin and 1 wavy) you put a thin one either side of the wavy one in the bottom groove.

As for honing it is necessary if you want the new rings to bed in to the cylinder properly

 

[needapitty]

if i was putting a new highcomp piston in chickin i would hone the cylinder for sure mate

 

[Chickenwingz]

How much does it cost to get it honed?, can it be honed with sandpaper?

 

[liljohn_92]

Couldn't tell you a price really but as a guess $50, i hone my own cylinders, You can get the honing tools from most auto parts stores and you just put it in a drill.

You can do a dodgy hone with sandpaper but you won't be doing it evenly.

When i set the engine to TDC then go to undo the cam sprocket bolts The engine just turns over and i cannot undo the bolts, how can i stop this?

 

[timeeh]

1) Put it in gear
2) Put a socket rachet on your stator nut
3) While holding onto the rachet then undo the bolts on your cam.

put the bottom ones on first. Install from the top and go from one groove to the next till you get them in the right groove. Be patient and gentle as rings are easy to snap if too much force is used.

 

[GooseMan]

don't bend em either, to help get em in the right order copy the old piston and rings.
