Sorry for the delayed reply! Nice, what do you ride now? How did you find the Zontes, any hot tips of anything? Lol

Wondering if there are any other members on here who own or have owned a Zontes Tiger. I have the 125 version. Thought it might be handy to pick some of your brains if possible so I can get to know my bike a bit better, and tackle a few issues. Thanks

Thanks bud. Thanks for reading! Thanks Bob. Yes definitely learning a lot since owning the bike. I suppose that's the silver lining to things going wrong haha, you start researching and learning how things work.

Little update for those Interested. I ordered the sprocket and retainer bracket and installed it at work. Also cleaned, lubed and adjusted the chain. Drove it home no issues, all seems well! As I didn't have a manual, I adjusted the slack for about 30mm (what seemed to be the average measurement for other bikes on forums). Once I tightened it all Bolts it actually ended up a bit below 30mm. I planned to recheck it all today on my day off so I can take some more time and recheck nuts all around the bike, and luckily I noticed that it has the slack measurement written on the chain guard... 15mm. So I will re-adjust to this. Also tip for anyone else with zontes tiger in same position. When I was searching for parts I could only find the sprocket on its own (no bolts no retainer bracket). It worked out alot cheaper and easier buying a front sprocket kit for a 125 pitbike (sprocket, 2xbolts and retainer bracket included) for £6! Just had to make sure it was the same type, which is 428 15t 20mm. Took about 5mins to install, straight on no problem. Thanks to everyone for the advice. Learned a lot.

Yea, well up until now I have just been tightening it by judgement. So e.g. spark plugs im cautious not to over do, but other heavy duty nuts/bolts I'll give a good yank on. I thought about the torque wrench because I watched a short tutorial on replacing chains and the guy used torque wrench for the rear wheel nuts. As some of you have pointed out, seems a useful bit of kit to have, but I suppose it's only useful if you have the right info on how tight each section has to be, otherwise it goes back to guess work. I've ordered the sprocket btw, hopefully be with me in the next couple of days, and I've ordered chain cleaner and lube. Should be able to just fix it at work and drive back. Hopefully goes all smoothly lol

Thanks. Yea I checked the condition of the chain and rear sprocket and they seem good. I will definitely clean and re-oil as you suggested. Well observed , its dry as a desert in there . The chain looks straight out of the box but even a new chain needs lubrication . Presumably the person who recently fitted this chain was incapable of adequately tightening two bolts . One falling out is unfortunate but to lose another is just careless. Probably a good idea for the owner to check the rear sprocket and anything else this monkey has waved a spanner at. Haha, yea I will give the rest a looking over. What are the list of nuts that should be part of my regular checks or tightening? Also, I think I'm going to get a torque wrench. As I mentioned before I can't find the manual or much info on the zontes tiger, but are the rear wheel bolts generally tightened to 100nm? I think that's what I recall seeing for other bikes...or does it differ quite a bit for different bikes. Cheers Thanks

Having a look and found two sprockets for the zontes on eBay. One is 15t, which I assume is the original, and the other is a 17t upgrade. I'll probably stick to the original, but out of curiosity how would more teeth benefit? Im having trouble trying to find the bracket/retainer for the sprocket. There aren't any listed for the zontes, so I am unsure which size to go for. Tried contacting a Zontes dealer, waiting on a response..

Lovely mate, thanks for breaking it down. Yes, but just to point out the obvious 'just in case'... There will be another one on the other side of swing arm, both need to be adjusted together (normally marks on swing arm to match both), otherwise you'll end up with a wonky wheel. cheers mate, feel free to point out the obvious anytime with me lol could always do without a wonky wheel. Unfortunately it didn't come with a manual, and they seem to be like gold dust for this bike lol

Thanks guys. Is it likely that this slotted washer comes with the sprockets, or is it a separate purchase. I'll email the seller and ask. And thanks for the tip lol I definitely would have been questioning any wobbly movement!

Back again. Unfortunately my previpus post for this problem got deleted in the crash. Recap: Went to leave work, drove round the corner and got stranded at the lights. Bike went into gear but just revved away going nowhere. Pulled over, saw that the chain was slack, but still on the back sprocket. There is a panel covering the front panel and it was dark so I couldn't see. I snapped some pics and wheeled it back to work and got the train home. The pics: Didn't realise this but a friendly user from this forum pointed out that you can actually see the sprocket popped off in this picture. Unfortunately the sprocket must have fallen off whilst I rolled it back to work. Come back to work with some tools and just removed the panel to see no sprocket pics: So I'll have to order a sprocket replacement (maybe a whole chain and sprocket kit). I was wondering, how is the front sprocket secured once it's slotted into position? I can't see any threads or anything, please advise. Also, to adjust the chain, would I just need to undo the main nut on the back wheel, and adjust using the other chrome bolt sticking out, if that made sense... Thanks (Forgot to mention I am new to motorcycles and this is my first owned bike. Sorry for any stupid questions that may seem obvious, still learning!)

Ah good. Thanks guys

Removed my spark plug to have a look to see if my mixture was correct. I've been using images in the net to try to gauge whether it's okay, and it seems though it looks optimal, except maybe some excess sootyness on the ring? What do you guys think...

Unfortunately not pal, they don't seem to have for zontes. Must not be a common brand even in china! loll You know it mate. He hates all these new motors because they are all electrics nowadays. He loves to remind me how back in the day you could fix your car with a screwdriver or just make a part for it haha.

Thanks for the reply guys. Ok so I had no luck with any auto locksmiths, nobody has the blank for it, and zontes don't sell any. The only other option was to by a new ignition barrel and fuel cap set with new keys. However, my old man was convinced he could make one, so he dug out a bit of scrap metal, use the original key as a te,player and filed me a new key...which works! lol it's not perfect, but at least I can ride it again. After looking around more online, I found some blank scooter keys from china which seem to be the right measurements. It will be a while until they get here but when they do I'll take them down to a locksmith with the original and hopefully get another two keys cut!

Ok, so like a twat I managed to snap my key off in the steering wheel lock. The spare key the previous owner gave me is not a spare at all, so now I can't ride my bike because my only key is now snapped lol I managed to tweeze it out, but not had much luck finding a locksmith to make a replica for me. What are my options here? I have a zontes tiger 125. Thanks

Thanks for replies. Ah good to know that's normal. Didn't realise about the gasket. It didn't sound like it was blowing or anything, so that's good. Yea I'm warming it up quite a bit, ridden it up and down my road, it seems to drive and pull fine. Haven't taken it on a longer ride yet, or topped it up with fuel myself. I got my CBT tomorrow, so hopefully ill be able to insure and get it on the road properly within the next couple of weeks.

I have also just noticed that there doesn't seem to be a gasket on the exhaust manifold?? Is there supposed to be a gap like this?

update. Changed the plug today, no improvement. Adjusted the pilot air screw afterwards to see if I could improve but still no luck. here is a short vid...  ">

yep just ordered one off the bay. Should be with me in a day or two, I'll swap that and hopefully see an improvement.

sorry pal couldn't see what you were trying to send there! Said file was not found Yeah, I know , it was supposed to be an owners manual PDF. that would have been very handy lol

OK I took some pictures as promised... Airbox and filter: Spark plug (will order a CR7E asap and try that) The mixture/pilot air screw location I wasn't sure what the following things were for, could someone take a look and explain please: something to do with breathing of the bike? and what do these air pipes in this airbox do? thanks again

sorry pal couldn't see what you were trying to send there! Said file was not found

You should use the exact plug that is specified by the manufacturer. But , yes , they probably are pretty much the same because the vast majority of Chinese bikes of every shape and size use an engine ripped off from the humble Honda CG125. Yea unfortunately I don't have a manual with it to get the specs from. I thought I'd be able to find one online easy enough but apparently it's like gold dust lol what spark plug does the Honda use? Good morning, ok , its not based on a Honda CG125 , it looks more YBR 125 to me . Anyway , its an NGK CR7E plug but apparently there is a better alternative. See this link , http://zontes-reborn.blogspot.com/2015/03/one-year-on.html?m=1 thanks for taking the time to find that bud. I checked my plug, its NGK CR8E...so i'll give that a swap over and see what happens.

I had a look at the spark plug, looked okay, but still have it a clean. No improvements. Maybe I'll just change it anyway. How would I know if the plug I have now is suitable? 125s generally use the same type, or do they vary with different bikes?
