In terms of where to go, depends how much time you want to invest. Chinesium heads will probably be OK, but unlikely to last as well. OEM heads - are they obtainable? Likely to be expensive. Either way that assumes the problem is either in the head and/or you're going to be able to identify and resolve any other issues. If you can't easily suss the issue, I'd be tempted to try and find a s/h engine somewhere. Alternatively, if you do want to go for a Chinese engine, again going off my C90 experience, see if you can get a Chinese clone but fit the carb from your bike - they're usually much higher quality than the Chinese ones and will make setting the engine up much easier. This obviously is only going to work if the engine is a clone though!
Rattling generally suggests movement where there shouldn't be any, either something loose or something worn. It sounds probable it's the latter, whether due to oil starvation or accelerated wear from the previous incidents. |
So, I had the head cover off again this morning, and there's plenty of oil but it turns out there's a rather nice gouge in one of the journals that I'm not convinced is factory and looks like it could be causing the problem. So the options I have are either a chinesium head for about 120 or a second hand GZ engine for about 420... |
