Hello forum, What are the valve cleareances? The mechanic that just changed my rear tyre said after 24,000kms I (about now) I should get my "valve clearances" checked out. About a month ago I had the following service at 20,500kms: 1/ Change Engine Oil; 2/ Change Engine Oil Filter; 3/ Change Transfer Case Oil; 4/ 4 New Spark Plugs; 5/ Replace Rear Brake Pads; 6/ Replace Air Filter; 7/ Remove Front Forks. Drain and Replace Fork Oil; 8/ Grease Steering Head Bearings; 9/ Fit Grease Nipple To Steering Head; 10/ Adjust Steering Head Bearings; 11/ Tune and Adjust Carby; 12/ Remove Front Wheel Bearings and Re Pack - Grease; 13/ Straighten L/H Front Disc; 14/ Bleed Front Brakes; 15/ Oil Clutch Cables; 16/ Oil Accelerator Cables; 17/ Adjust Clutch Cables; 18/ Check Tyre Pressures; 21/ Add Fuel Cleaner To Tank; Can't see any "Checked Valve Clearances" here. Is checking the valve clearances something only a mechanic should attempt? Thank you.
