Changed the spark plugs on my 2005 mcx before putting it away for the winter. I didn't think of it then, but now that Iím getting ready to use it was I suppose to gap the spark plugs, and if so what's the gapping?

Thanks Ed

Always good idea to gap plugs before installing, even the ones that come pre-gapped. Read this thread. But basically, if they are platnium then 0.060". If you use the plugs that Engine Nut recommends 0.045".

I just replaced mine this seaon with the MR43LTS gapped at .045". I will know this weekend, how they work out.

Also, check you cap and rotor. Mine after a couple season has corrosion on the metal tabs in the top of the cap. You can scrape clean or replace cap and rotor.
