Phenolic Amal Carburetor Insulator 28mm Triumph Norton BSA 250 500 650 Thick | eBay

you could buy a piece of phenolic/bakelite and make your own insulators
phenolic sheet

the Z's head bolt angle is a different angle to the YX160's

ive emailed oo racing, see what they say. they would have to have something surely.

ive emailed oo racing, see what they say. they would have to have something surely.

Maybe take a couple of photos with the measuring tape and someone might have one hanging around!!??

 

[gottagetacheaperhobby]

i will tomorrow stu, all though i doubt anyone will have what i need, its a weird angle.most seem to be around 45 degrees roughly, but because of the angle of the intake on the head, i need something closer to 25/30 degrees, and around 10mm shorter than the original manifold.

 

[gottagetacheaperhobby]

haven't got one with a tape there but this is the way she sits atm

 

[my67xr]

ok your engine is the same as my Z155HO,
you are lucky you asked this question now, my manifold is only half polished atm (other side)
when it is all done there'll be no numbers on it, so hopefully you can match them up with one on ebay etc ?

the manifold sits the carby up a bit, and it's a pretty short manifold too compared to a Lifan one.

 

[gottagetacheaperhobby]

you are a legend craig, once again you have saved my ass.

 

[my67xr]

it should've clicked earlier with me but i've been preoccupied out in the shed all weekend.

here is one from 00Racing-
OORacing - performance monkey bike, pit bike, madass, zoomer, dirt bike components - Manifold for YX 150/160 with KSR port corrected float angle VM carbs (Powered by CubeCart)

lol, shed clean ups can do that to ya. cheers mate i did see that one, will be ordering tomorrow hopefully

o ok, im looking into the liquid image cam i think they are 140 bucks, just dont have the cash for a gopro.
will it be detrimental to use a thin layer of silicone around my manifold adapter to seal the blasted thing? ive tried sanding it back and making up a thicker gasket but its still pulling air in.

I didnt see this....I use one of these! Made in same factory as the gopros, its done me well so far! Hasnt skipped a beat and produces some decent looking footage! Get a decent size class 10 8 Gig or bigger SD card and you'll be good for under $100 :thumbup: https://www.bigw.com.au/electronics/cameras/digital-cameras/bpnBIGW_0000000334885/3sixt-hd-sports-action-cam

i just found this one too, looks very close shape/angle

 

[gottagetacheaperhobby]

cheers for that info stu, will be getting one as soon as all three bikes are up and running
i did see the tb inlet craig, but how short it is worries me, as the daytona manifold i got with the pe28 for the braaap looks really similar and mine wont clear the bolt on the cam tensioner.
dont suppose you would swap yours for my longer one and the daytona manifold?

 

[my67xr]

nah, i will need mine sorry.
anyone that sells a bike with a Z155HO/Z160HO should stock them i would think ?
have you tried Motorbike city ?


here's a couple of better pics of mine, looks like it has about a 23° angle (layed back at the top) carby flange.











the carby mounting face sits at about 23° back at the top to correct the float bowl angle



this one was hard to get a good shot, but i reckon it's around 15°

 

[gottagetacheaperhobby]

thats ok mate, had to ask thanks heaps for those pics, i havnt tried motorbike city yet but i will. the local shop here is a atomik dealer and pretty sure they are all yx donks so wont have what i need. they never do thats why dxz and ebay get most of my cash lol.

 

[my67xr]

the Atomik Comp L 160/172 have a Z160HO based engine , but they use an extension between manifold and carby
Comp L 160cc - Competition Bike - Dirt Bikes

 

[my67xr]

the one that DHZ supply with their Z160HO looks different again

 

[gottagetacheaperhobby]

thats the one i have that is to high by about 10mm grrr. not having much luck finding the one the same as yours, i emailed motorbike city, hopefully they can help

how about turning it upside down? although then it might be angled out too much..

 

[gottagetacheaperhobby]

wont clear the timing chain adjuster
