Kangchao Kc 118

[SilvaSoul]

To begin with, i just joined BCF and i wasnt sure what section to put this post in, if its in the wrong section then i apologise in advance. also i have very little knowledge on bikes because i dont have anyone around to teach me so some of the questions i am about to ask may sound really stupid so sorry in advance again.

i am 18 and couldnt wait to start riding and stupidly bought a chinese bike because of my low budget, despite being told by others not to buy it. the bike i bought is a kangchao kc 118 ( i do not recommend buying this bike ) looks like the one in this link but in all red: https://www.bikechatforums.com/files/125cc.jpg. i have had the bike for a couple of months now and theres a few problems with it.

these are the problems i have had with my specific bike, i do not think they will be the same for everyone else.

1. the fuel tap seems to have malfunctioned, causing petrol to leak down the side of the bike.i have had to get the petrol line connected directly to the carburetor.

2. the petrol tank, where the petrol is filled and petrol lid closes, there is paint, every time you fill up and close the petrol lid the paint gets scraped off and falls into the petrol causing it to block the filters more. i have had to get the petrol lid removed and the inside sanded down to removed the paint.

3. the bike makes a squeaking noise when it slows down, i have to press the back brake to stop it from happening for a little while.

4. the side mirrors on the bike have to be screwed on to the frame but the frame which holds them has cracked off.

5. the suspension spring at the back has been loosened as much as it can but can still feel every single bump in a road, i know sports bike are generally like this but this is overkill.

6. this is a major problem i have had with the bike, after riding it for a while , it starts to slow down and when revved a bit more still slows down until it cuts out in 2nd,3rd and 4th gear. when its stopped after this happens and i try to roll the bike back or forward and it does not move even with the clutch held or the gear changed. when you try driving again, starting in first gear and revving as much as you normally would it starts to over rev. when i turn it off completely and let it cool down for about 5-10 minutes it starts to work again properly until the next time it happens.

now, with that out the way i would like to ask:

a. is it at all possible to put a different 125 cc engine in a frame, eg
is it possible to replace this bikes engine with a cbr125'S?

b. can anyone maybe identify what the problem is for no.6 above using what i have written?

i know i should sell it and get a decent one but im only going to be using it for a year then i plan on doing an A2 and getting a bigger bike. also i would not be able to recover as much money as i have put into this bike even if i fixed all the problems so the only option i have is to use it and get what i can when im done.

i will try to post a video sometime of problem no.6 if possible.

if anyone can provide a reply in regards to these questions, i would really appreciate it, thanks in advance.

A) My mate replaced the 125 chinese built engine in his missus' Hongadou 125 trailie thing with a CG lump.

B) No idea. Sorry mate.

A. There wouldn't be much point really, it would still be in an absolutely shocking bike. Spend the time you could spend doing that working, and buy a better bike

thanks for the replies, i think if its gonna take too much work i may as well just drive it as it is for now then scrap it in a month or so and get a honda or something.

just another question , are hyosung gt125r's any good? im interested in them and think its better to research first before i make the same mistake again . thanks again.

The amount that it'd cost you to put most engines in would probably end up being a lot more than buying that bike in the first place.

It sounds like your engine is ceasing in a minor way. If this is the case, this is a very bad thing. If your bike is watercooled, have you checked the water level? Have you checked the oil?

[stirlinggaz]

hi,
i've owned a few chinese bikes, but dont recognise the name.
& your linky aint working!
any chance of a pic?
do you know what engine is in it? (number will be on left, towards the bottom, starting 156fmi or similar)
& what carb?
i do know that some of the subframe welding can be a bit dodgy, usally any leaks are down to the absence of o-rings.
cheers,

hi,
i watched these bikes on ebay, as i have never seen them before.
i hope you didnt pay too much!. (as i seen what they originally went for brand new-i was even tempted myself)
anyway, nice looking but as with all chinese bikes have a closer look!
sorry i dont actually know that model, seems theres very few about, being quite new.
have a look at the engine number & carb & we'll take it from there.
cheers,
GAZ
edit - upon closer looking, it seems to be the bog standard 156FMI engine-(looks like a combination of all sorts of chinese bikes -"tsa bitsa"
have a look at engine variant & carb type.
tbh, these engines ar usually quite reliable, unless overfilled with oil (should only take 0.9l)
usually most problems stem from the cheap electrics (you do have a decent plug in , not the chinese one right?), poor assembly & dodgy carbs (easy replaced with 29mm mikuni).
have a closer look.
as for the welds - sometimes its just the cheap paint on the frames that peel off, exposing the bare metal, speeding up corrosion. though i've seen some shocking welds on chinese bikes!

[SilvaSoul]

havent got around to opening the engine up at the moment, gonna get it serviced this weekend hopefully so ill get the mechanic to write down the carb number. i found the engine type on the certificate of conformity, its 154FMI

also what do you mean by plug in , is it the spark plug or ?

It is insured at least "Third Party, Fire and Theft" I hope.
Fire will be your best option.

lol i was thinking of that too :p thanks for the help anyways guys , appreciate it. just gonna get this one sold somehow and go for my A2 and get a bigger bike and restrict it or something.

[lilvfr400boy]

hello i am somewhat of an expert on this bike now as my brother has had one for over 2 years, we had all the same problems( i am a bike mechanic by the way) i hanged the exhaust system the carb the engine and the rear shock immediately and since havent had one problem in 10000 miles, it is a standard pitbike engine in this bike so is very easy to get parts and stuff for

jus checked my email and saw a new reply to this, i think it may be my luck but i've had a really crap experience with this bike:

- fairing cracked when delivered
- not receiving any replacements
- problem 6 from the main post above ( the bike cutting out)
- fuel tap going
- mirrors broke off because of the vibration and poor welding

and that was all within the first month or so after buying it brand new! then i read that they were stopping production of these bikes, meaning it may be harder to get the parts for it!

To top it all off the week i was going to sell it, it was stolen, stripped of everything but bare basics then hot wired driven around the canal nearby and the insurance company then found it and took it to their compound after i reported it stolen and made a claim.

the insurance company doubled the excess as i had parked it in the front garden as opposed to the back garden due to having guests and come home late when they were asleep. managed to settle for ?200 and the bike back.

now if that was the end, i would of been happy.....

i was told i had to go and collect the bike from sandy which is about a 2 hour drive from where i live, so my dad took me, we waited for an hour so they could get the bike out and loaded it into the car. when we arrived home we noticed the compound workers had left the oil cap open so all the oil all over the rear seats and boot, costing a further ?70-80 for new seats and mats.

and then i rerecieved SORN penalty, because i couldnt declare as the insurance company had taken the bike along with all documents, despite phoning DVLA and asking if there was anything i would need to send to them before they took it. luckily i wrote to them and it was wawavered

Now it lays in my back garden waiting for me to strip it apart and sell the parts. The engine, rims and tyres,rear swswingarmfront forks, disk brakes, suspension springs and ala lotore are still intact and in a good condition, so if anyone in the UK is interested in spare parts i would be more then happy to sell them. if you are interested please PM me and i can take pictures of the parts for you or perhaps arrange a viewing.

[MaybeGuy]

i doubt anyone would take it off your hands for free.

like seb said, i had frame problems. not with the welds though, mine just snapped halfway along. nowhere near any welds at all.

i guess thats what cheap quality is really, they dont realise thier business could thrive if they focused more on quality and sales rather then sales alone.

oh forgot to mention found a solution for problem 6, change the oil you get in the bike as soon as you get it. wish i had realised earlier but changing it fixed it.

[lilvfr400boy]

the more expensive thing to do is to take it to your local engineers and as for a trellis frame to be made to replace the original frame with a steel tube trellis frame. expensive but potentially a lot cheaper then a cbr 125 all together. if kangchao had taken the time to just build a proper frame and go to mikuni for there carbs, musashi for the exhausts they would have been fine. like i said in earlier posts my brothers has done 10000 miles now without any real costs. it has required modification after modification though
