I just had my 2003 Triumph Bonneville serviced after covering 12000 miles (at a Non Triumph Garage but very good). Started running rough after being very well behaved. Valve clearences were out, new shims ordered and fitted. But although full power and running great, tappets are very noisy.
Any ideas? Valve clearences were re-checked and spot on.
i wouldnt worry too much as long as it running ok, it will be noisier if it had no clearances before they did it but i expect you have told the garage and they have explained that too anyway the clearances are sometimes big and make a tapping noise but its usually better when its warm and it really does need them!
