Hi I'm new to the forum Ive just bought a Jialing 125, 1999 for a couple of hundred quid to trot about on when the sun is shining and to see how much I enjoy riding a bike after owning a 50cc Suzuki some 30 years ago... I know its Chinese and its probably a pile of poop etc. but it runs pretty well, I assume anything that is going to fall off will probably have done it by now and it will do me ok until I decide to give it up or take my test and get something bigger. The problem I have is that I got a flat, someone offered to repair it for me, couldnt do it, lost the the flange off the exhaust and I'm now left with a bike with a flat tyre and no exhaust!! Not pleased.. I figure I can probalby put the exhaust back on my self so Ive purchased a new flange and gasket. Can anyone give me any tips on fitting it? i.e. the order of the various bits, the part that is confusing me is a split collett, Im not sure how/where this part fits, eveything else seems pretty straight forward. Thanks in advance for any advice!!
