Z155 different to Z155HO??

[rumble]

Is there a difference in the engine or are they the same.

If they are different, in what way.

 

[The_GDFP]

Ho version has a closer ratio trans, slingless crank with oil filter cover, 6-disk clutch, "normal" Chinese primary gear ratio of 3.72 v. the 4.06 of the Z155-no-ho and stock Honda 50's, and a few less trans issues. Still needs the end play on the drum and tranny shafts fixed to live very long.

i sware there is like 3000000000000000000 of these threads there is google not having a go but im just saying

GDFP, so the Z155 dosent have the oil filter cover and is the older version of the new Z155HO with the oil filter cover....

So all Z155 with the oil filter cover are HO's??

Minibiker, the problem with :google: is everyone calls them different things, depending on what they are trying to sell. If you can be bothered have a look, and then let me know how you tell them apart, although if you have read 300000000000000 threads about them you probably already do :boxing:

that problem was fixed in the early z155's.. like over 12months ago..

and yeah there is a big problem with engine names these day.. we call it this, the chinese call it that and the amercians call it something else..

most chinese companies call them z150's, pitster pro usa still call the new motors z155.. Mini bike and pit bike engines, GPX Lifan and more

Last week I put a PSTO together and it had glue over the number on the barrel and when I cleaned the gue off it said 160 under it but had been scratched at with a sharp implement at some stage in china I take it.

 

[sean01]

yeah, zongshen and yx probly get their cylinders from the same place and just use what ever is in stock..

the 150,155,160 all share the same bore size.. which is outlined in the top line of the engine number.. 60mm

come to think of it, iv actually seen z155's with no markings on the barrel. the numbers had been sanded off lol
