tb 60mm piston and v2 head is a sick setup / still 155cc but packs a good punch .

yes you need that adapter if running a taky decomp cam on the "china" engine as the cams are originally designed for klx110's which have a little different cam sprockets.

I would definately go a v2 head with a taky decomp cam before going bigger bore .
 
I thanks woggy, but why would u wait? To get used to the power difference? N other than having the pain of having to push the button on the tb decomp why do u suggest I do go with the taky
 
i only skimmed through the thread and thought you where gonna go 1 or the other (v2 or 64mm bore)

Do it right the first time i guess with the cam?

The buttons can be abit cheap and faulty at times , and yer i know i would forget the button alot more then i remember it .. i would rather decomp cam working with every single kick.

plus you can choose from a good range of grinds with the taky cams and they would also be abit higher quality then the tb cams .
 
Appreciate your input mate, just but confused as I like the idea of the decomp cam n understand the principle n agree with u guys but still wondering why I getn told different by others saying the standard cam in the tb head is better performing than the taky ???.... Hmmf just wanted you guys opinion on it too :)
 
When I built my race engine two years ago, I put in the big bore 184, v2 head (no button) with taky s25 de-comp cam with the adaptor.

I raced it for 2 or 3 rounds of vcm and was running sweet, but found I was lacking peak revs with the s25 cam on the big tracks we race on.

I then changed the cam to an s35 non de-comp cam from TB parts and found the extra revs I was looking for, but did lose a tiny bit of torque off the bottom.

I found with the s35 cam, I can start the engine no problem without a de-comp. Just get top dead centre and a good kick.

I would recommend fitting an adjustable Lifan outer rotor ignition to help with kick back when starting. Kick back is what damages the gears and cases. It happens because the standard zonga ignition sometimes has too much advance at start up and cannot be adjusted, where as the Lifan can.

Hope to have helped, cheers, Kosta.
 
Hahaha thanks Kosta, wicked to get all you guys input on this kinda made my decision harder now lol no decomp?..........
So is the s35 the cam you would get with the decomp push button v2 head as standard?

Should i just get the kit with decomp n be done with it? I never gonna catch u n mike anyway haha
 
Great thread Roy!!! I've been keeping an eye on it to help me decide what to do as well ;)

Yes, pretty sure the v2 comes with the s35 standard.

I would get the v2 with de-comp button, s35(comes standard I think), titanium retainers, TB inlet manifold, big bore kit and either a Keihin pe28 or pwk28 carby.

Basically, get this. Classic Honda 50's Australia - TB 170cc to 184cc Bore Kit, Race Head V2, and 28mm Carb Kit [TBW9040]

Just add the titanium retainers and de-comp button when you order.

Keep the questions coming. We'll get ya sorted.

What is the carby in that kit exactly Kosta?? All it says is it's a 28mm performance?
 
It's sort of a copy of a keihin pe28 carb. They seem to work pretty well, but not as high a quality as a keihin.

You can request to leave it out of the kit which will reduce the price.

:thumbup:sounds like a plan, n ur suggestions for bottom end?
 
Aaaah.?... I got a 2012 motovert 160r with the ho with oil filter already sorry if i wasnt clear just meant clutch springs and basket or anything else to consider

P.s this is kosta from vcm yeah? I met u at undera? I was the bloke in the sling :)
 
Yeah it's me from vcm lol.. how's the shoulder feeling with the plate in there?

I'd just put the hd springs for the clutch and leave it at that as far as the bottom end goes. I've been running that set up for a few years now and just replace clutch plates as needed.

You coming to Yarrum?
 
Sweet, yeah im ok mate, n yeah ill be down to watch yas all bang bars....
Thanks heaps for the info basically now i just gotta make my mind up if i just go the kit with decomp n retainers n do the springs. ?... Wont that take it to 184 not 177?

N just so i clear, , so u basically running the 160 ho, with 64mm piston n barrel, n then the non decomp version of the v2 head with upgraded retainers, then just heavy duty clutch springs in the bottom end? N just find tdc n have no issues with starts or damaging anything else?

The big bore kit ie.64mm piston and barrel, will make the z160ho a 177cc because it's not a true 160cc to begin with, it's 155cc. The yx160 is a true 160cc engine and therefore will make a 184cc with the 64mm kit.

And yeah that's pretty much what I'm running in my engine and haven't had any problems. I would recommend getting the de-comp button installed in the v2, just so it's there if you do need it.

Glad to be of help.
 
:five: thanks heaps kosta, n thanks to everyone eles input the MR Gods have spoken!!! Just gotta find the cash for everything now

I think you will find the 160ho is a true 160 and when fitted with a 64mm barrel and piston it brings it up to a 184cc.
The previous engine being the 155z fitted with the 64mm barrel and piston becomes a 177cc.

The z160ho is really a 155cc engine, same as the previous z155. They just call them 160's for marketing hype.
The yx160 and z160ho both have 60mm pistons standard, but the yx has a slightly longer stroke than the zonga, and that's why the zonga loses 5cc's vs the yx.
 
learning so much from you blokes its nuts, now just gotta fugure out how to hold ya up at a start Kosta, maybe then i wont get lapped when i come out :)

Ooh sounds like there might be a 5 buck lottery ticket on this. Lol
Im lead to believe that the ho has a slightly longer stroke than the earlier model.
If what your saying is right that would mean not many people at all are running 184 but in fact a 177
