Iv just had my valve shims checked at 37K miles ,yea i know it should of been done at 28K but there are reasons for that being missed,
All Inlet valves were in tolerance and one exhaust valve
,the other three were out but the inside left hand cylinder exhaust valve was way out.
The camchain was slightly worn but the mechanic said nowt to worry about and the carbs were balanced aswell
cost of 3 shims were aprox in UK = USA $. $17.25, coolant $10,Labor $210 total of $237.25
I was expecting them all to be out of tolerance on the valve shims but was surprized to find inlet valves were ok.
