The thing is every bike will have it's problems and weak points, some more than others. Honda's generally are the most reliable out of the bunch. The VTR's weak point is the CCT's and Regulator Rectifier. VTR's are not the only bike that have had CCT problems there are others too. And regulator rectifiers can be a problem on any older bike. I will guarantee any other bike you purchase will have problems of it's own, as these things are always built to a budget at the factory's and manufacturers have to cut corners somewhere.decision time stump up or sell up!
For those that are less mechanically minded there may be someone on the forum near to you that may volunteer to lend you a hand. Or you could wait until the forum has a workshop day near to you that you could attend where there will be people on hand to help. Otherwise it's down to a garage to fit manuals. Most mechanics in a garage would not have heard of the stopper mod but If you print the instructions and diagram off I'm sure they would be able to follow them easily enough. There's basically a hollow part in the shaft of the CCT so when/if the spring breaks it becomes so slack the cam chain jumps of the cam sprocket causing valves to crash into pistons and bend. By inserting a piece of 8MM bar cut down to size (an M8 bolt is good enough) into the hollow part, this stops the tensioner becoming so slack that it causes major damage.
Honda are aware of the problem though they won't admit it. It would have cost them a heck of a lot of money (instead of making from damaged parts) to do a re-call on all VTR at the time.
