Having got the valves on the CG adjusted thanks to some fine WB help, I now seem to have new problems... :
He has always been pretty noisy compared to other 125s, I assumed due to age and design, but now it's getting rather noticeable and worrying as he has been doing his best thumpy-pitbike-steam-engine impression lately :-/
- The most worrying noise is the 'thumping' from the engine
- if I come to a sharpish halt, i.e. without pulling in the clutch and going down the gears slowly, there's an odd 'puffing' noise. (To my inexpert ears that sounded like a leak in the exhaust but I've looked and although it's rusty it appears to only have holes where it should have holes...)
Any ideas? Would welcome anyone who's local having a listen to help advise!
I'm not afraid to take things apart (with some help), but I'd just like to have a few ideas first as I use him for work, which means he can't be off the road for more than 2 days at a stretch (weekends) or I need to get another bike..!
