I worked at Honda Sydney in the late 60's early 70's and a few of us modified the CT90's we used to fit the piston from a CB175 and because the piston was so high compression we had to turn the crown down on the lathe so it would not hit the head and then had to redo the valve inset in the piston to take the CB175 bigger valves ,then do a different profile for the cam to give it a better duration and lift ..got a Bing 32mm carby off an early BMW and fitted to head via modified intake manifold that let the carby hang out to the side Made an exhaust to suit and tested the machine ....clutch was not strong enough and would let go under hard throttle but the main problem was when it got to high in revs the points would bounce and would detonate and burn a hole in the piston ...gave up and waited for CDI ignition but never went back ...but!!! when it went it was a mongrel with loads of power for about 20 minutes...wheel stood under throttle in all the 3 gears
Hi, Just wondering if you have ran it yet? I have a YX160 bored to 190cc with 30mm flat slide carb and I can only get 105kph out of it, what does yours do?
I also have a chinese engine Lifan125. Not strong as the Japanese ones, but so cheap to repair and tune. mine can do 74mph max now. I wonder what the Forza155 can do. Too bad you didn't test ride it.
I did! but I never got the video that a guy shot for me- This was a while ago now and Im better equipped myself for videoing. I got 166 kph after a couple of sprocket changes. I wish that I had kept it and continued with it
okay 166kph not bad, i'm planning to swap a bigger one later. I'm bored with mine. You still have the bike? I like it, it looks like a southeast asian drag bike :)
Lol!~ the asians do some wierd shit with vehicles eh!. I like the drag boats with surface drive props and no safety gear! th-cam.com/video/9CPZ3svFfn0/w-d-xo.html
Yeah lol It looks like a surfboard with 2 stroke motorcycle engine attached to it, these guys mainly focus on lightweight. Pretty damn fast than the guys in my country. th-cam.com/video/sKSx983h8FM/w-d-xo.html
Is there a lifan 250, and would it fit on the CT110 body? I'm a big guy and want an auxilliary tank too for trail riding/camping, so need something capable of getting upto 110-130kph. I'm exploring the ct110 as a donor body since they're very cheap and common in Australia
haha for years Iv wanted to convert my fiat 126 into a monster .. unfortunatly she sits and waits for funding. Nice bike mate. great to see somthing special made out of somthing simple :)
This guy has got no clue about how to start that engine.Also it is critical you let these things warm up for at least 3 min to let the oil pressure drop before you go reving the fuck out of it,hence the oil spewing out.Nice looking bike but.

Made an exhaust to suit and tested the machine ....clutch was not strong enough and would let go under hard throttle but the main problem was when it got to high in revs the points would bounce and would detonate and burn a hole in the piston ...gave up and waited for CDI ignition but never went back ...but!!! when it went it was a mongrel with loads of power for about 20 minutes...wheel stood under throttle in all the 3 gears
was it just me or did anyone else see it spewing the oil out of the air box at the end
i know right?
i dont know whether he seen it and was trying not to acknowledge it or whether it was just a blonde moment lol
I did two years later lol
Hahaha yeh I seen that to
Crankcase breather.
tyres nicely pumped
Wow this sounds so good and looks amazing!! Is the kit still available?
It’s not a bloody kid man you simply go to eBay by yourself a pitsterpro 160 motor and slap it straight a postie not hard work

Do you still ride that bike? I'm thinking about getting one
That 190cc can do at least 180kph, if you tune it right
sweet mate iv got a tf125 2 stroke in my ct90
Holy crap I was wanting to throw a 125 two stroke in mine the second I bought it. How hard was it??
What started poring out lol oil to full was the tube on
Did I see oil shooting out of the side?
Haters gonna hate. This bike is fuckin SWEET! Nicely done sir!
Wheres the dayglo saddlebags ?? and wheres my mail /!!!

look up the compound turbo ct110 from oz which has gone faster than 120 mph.
Starts first kick mate, why don't you post a video of you riding it.

Beautiful bike.
Sweet bike mate!

haha for years Iv wanted to convert my fiat 126 into a monster .. unfortunatly she sits and waits for funding. Nice bike mate. great to see somthing special made out of somthing simple :)
now that is just awesometastic!
it's amazing! nice work!
Where in nz can i get a yx160 engine?
Check out Dorothy fron one ten motorcycles in Australia, it is quick, around 80mph, yours looks nice, let us know what you get out of her :)
that thing is a boss!
Well, there was a waste of my time. I thought he would show us how fast it was. All I heard and saw was a motor start up and wind up. Big whup.
this is like the movie worlds fastest indian
Awsome engine and bike but you aint a clue how to start it. Try knocking it over the compression stroke then kick. It wont break your leg either
just because they make lots of engines doesn't mean they make good engines buddy.
Don't worry about these turkeys mate.
It will break the wrist of a postie to stop at every mailbox.
Anyone else here in 2021?
no comments
At that point it's not a postie
