If it was me rather than keep throwing money and not being sure if it's definitly going to solve your problems, I would put both bikes on eBay and put the money towards a brand new machine I think at £1070 on the road with a 2 year warranty you can't go wrong, they save you that in public transport in the first year alone, let's say you can raise £250 for both scoots selling them for spares you would need £820 towards the new scoot even if you finance that over the 2 years you would be talking less than £5 a week that's one days bus/train fair these days. plus no more worries about repair bills as you will have your warranty no mot for 3 years and will not need tyres or other wear and tear items as everything is shiney and new. compared to running a car for the last 18 years scootering feels so cheap I will probably just buy a new kymco every 3 years simply because if you start taking into account mots, tyres, drive belts etc that will start needing replacing as the scoot gets older you would not be far off the cost of a new machine, I think after 3 years and 30,000km you would have had your money's worth anything longer is a bonus. I would not go with any other manufacturer now as in the last 18 months of owning both scoots I have never had a days trouble out of mine or my wife's kymco's. previously we had new peugeot and scoots and both had there faults and could not rely on them seems since they went to china for production, i have owned quite a few scoots over the years and none worse than the new peugeots even my boatian was far more reliable. I know some kymco's are now made in china but at least the quality is still there were as Peugeot seems like its all about cost cutting and max profit....
