Just doing 24k service on Sprint 1050. On checking valve clearances all are in tolerance except one exhaust valve , this is a bit slack. I just tightly fit a 0.25mm gauge in. Thinking its not worth pulling the cams out for one shim as i presume its been like this a while. What do you guys think ? Also I amazed at how dirty the air filter is !!!
Normally valve clearances become tighter over time. If you have one a bit on the loose side I'd be tempted to leave it.
