Project XL185/CG250 swap - Page 3

XLsior · 09-02-2020, 04:24 PM

Hello 2LZ,

If people can put 140cc in Trail70s, a 190cc in ct110/posties

and I can fit a cg250 in an xl185.

I would be pretty confident a Chonda 250/300 would swish into an XL250 or XR of similar stature. It's basically the same engine.

The roached part is the issue, terminal rust and bent/cracked frames is out of my league. Here in Australia we don't have the population or massive bike riding culture so there isn't a glut of clapped out old Hondas here either. Every now and then they pop up. I actually found my bike when I was inquiring about a Yamaha AG200.

I am a firm believer in fate and destiny if your intentions are in the right place and you apply effort the universe tend s to reward you with a little patience.

You won't know if you don't try, no harm in asking your brother. the price might worth it regardless and if it doesn't work out some one else might make it.

Hey 2LZ,
Looking at an XL250 the engine mounts will take some fudgery and customization. I think it could be done but not a drop in fit like the engines based off Honda's original 125cc.

anything between XL/XR 125/200 seems to be compatible* for a direct swap CG clone.

I kept investigating 2LZ,

I think with a bit of bracket fabrication and if inclined to make/relocate a top engine mount a cg250 should would work.

found a xl250 reproduction bare frame image to wrap your head around and ponder.There appears to be some variation between years and models.

your brother in law's xl250 honda engine might be a keeper anyway.

Lipstick on a pig,

those with a keen eye will notice I filled in the 'Zongshen' embossed branding on the engine.

I used JBweld to fill in and sanded back flat along with any dents and scrapes.

Did they sell the CG in Oz?

XLsior · 09-03-2020, 03:57 AM

Hi Franque, yes the Chinese Honda clones are available in Australia, but I don't think any of them were fitted to road going motorbikes. As I mentioned previously I considered buying a new motor for about $800 but I could have bought a much better bike to start with with that kind of money. Then I found this used CG250 cheap so yeah...

From what I can tell all the engines used in the Australian market are intended for dirt/off road use.

franque · 09-03-2020, 05:10 AM

I was speaking more specifically of the Honda CG125.

XLsior · 09-03-2020, 05:20 AM

Don't think Legit honda CG125 were an Australian import.

I believe the CG was originally developed for the developing world markets with a limited release in Europe too.

So only Chinese CG clones are in Australia as far as I know.

However for me as a beginner, I actually rather admire the simplicity of the push rod OHV design.

What we do have are a lot of ex Australian postal service CT110 aka 'postie' bikes.

XLsior · 09-05-2020, 05:56 AM

Just out of curiosity anyone know the average MPG/Fuel consumption for a CG250 with a 30mm carby and mild head porting? The Xl tank is 7 Liters / 1.8 US gal.

Might be getting ahead of myself but a guys got to dream.

7 Liters maybe 200km if you set them somewhat lean.

Please round them up and send them to the US! Not sure what they go for there, but a nice CT90 or CT110 will sell for $2000-$2500. If they are cheap down-under it could be worth shipping.

Loved my CT90. Got over 100 mpg in the Hi gearing and chunked along on pretty much any trail in Lo.

Hi Goob, a postie in good shape goes for 1-2k AUD by the time you factor in the cost of shipping and exchange rates I doubt its worth it. You could always come buy 1 here and ride it back to the US, might be a crazy suggestion but people actually do that sort of thing. (C90Adventures) (makeyourbones) on YT for example.

When I say we have 'a lot' What I really mean is there a better chance than nothing. Australia is a big place but not whole lot in it.

Put it this way as Wild Dog suggested 7litres is about 200km In Australia 200km isn't considered very far at all...

franque · 09-05-2020, 01:19 PM

Depending on speed and stuff, 25 km/l is reasonable to expect, sometimes more, also depending on how you ride it.

XLsior · 09-08-2020, 06:41 PM

Attacking the rear splash guard. To use 2LZ terms its 'roached'. However no drama the top contour section was the only thing needed and in decent shape.

Rule 1: Don't over cut. It is easier to take a little bit away than putting it back.

I was going to curve match until I thought a bit at first and left the loom guard on the plastic edge.

I looked at the part number and found the year stamp 78/79/80/81 So even if the bike was manufactured early 90's I'm still calling early 80's design and engineering putting the the bike hypothetically the same age as me.

Just a quick little update oddjob sort of thing, every step makes a difference.

Don't worry i"ll cut down the M6 bolt.
