Valve tappet clearance check for 2004 Johnzuki?

[tony_cliffy]

Has anybody had their valve tappet clearance checked/adjusted for a Johnzuki 4 stroke and know what this cost? Also, were you out of adjustment or otherwise have an issue with it? I have not had this done on my 2004 DF115 (dealer did not do it at 10 hr inspection) and manual suggests biannually. Engine is running great. I'm probably around 175 hours +/- 25 hours.

If engine sounds ok, no raddles, and will do spec RPM at WOT then just run it and enjoy. I have checked my Jonzuki and its no big operation. If it makes you feel better order a new valve cover gasket first. Pull valve cover and check valve clearences. Intake and exhaust should both be .010 to .011. If you by chance should find one way off, then you will need to order a new shim to go under tappet. Clearences are not adjustable without replacing shims. A local fishing guide has 3000 hours on his Jonzuki and has not changed valve clearences.
