Whats the differance? because i want to buy one for my race motor build (184 + tbhead prolly)
 
It's the stroke im sure mate , a 184 kit in a 150 will be a 177 and in a 160 displacement will be 184.
 
thats a disadvantage i dont need... i guess i will keep my eye out for 2/hand 160's or better yet another bike
 
Even the 155z/160ho has the same crank as the 150 and is a 177 with a big bore kit also. But I love my gear ratios on the gpx/zonger motors.
 
i have a shop that is going to source some wholesale priced engines for me
 
If you are referring to the YX150 in the Atomik, the 10cc difference is the least of your worries... They run a CRF style head as opposed to the KLX head that YX also produce ;)
 
i got a pitpro 155z (zongshen) now so i think i have the klx style head...
there better because of the higher ports imo whereas the honda style makes a pretty sharp bend i dunno i have not had the head off yet lol :p

i think the close range gearbox will make all the difference
