Valve Adjustment Poll

Hi,

Really struggling to decide if I should get mine checked and adjusted (if needed). I've read and received so much contradictory info on this I thought the best way to get a valid perspective is to simply create a poll and see what the majority of owners have experienced. With this in mind, please take this poll and we can let the results speak for themselves.

I spent about $500 to have mine checked at about 24,000 miles. I'm now nearing 50,000 and I don't plan on checking them again. If I had checked them, and maybe adjusted them I'd probably be out over $1500. I can get a low miles motor off of eBay for less than that.

Why worry about it?

Unless you're wringing the piss out of your engine regularly, you can probably let it go 2 or 3 times longer than the manual says.

25k mile check, no problems. All valves near middle or range.

50k mile check, no problems and all valves were within measurement error of 25k mile check values.

If you read the concours 14 forum, this was always a hot topic. There are way many posts about this adjusting process going wrong, and causing real damage. Mis timed cams, parts being dropped into the engine, over torqued pieces, etc. . I dont recall anyone ever needing head work other than those people who screwed up the adjustment process.

I wonder if this adjustment procedure would even be recommended if we did not have emissions regulations? The worst value in this appears to be taking it to a shop and letting them do it. When the shops says, "no adjustment needed" the owners rarely believe that there was even a check.

I got a basket case 06 ZX14 I brought back to life years ago. The bike was treated fairly. Everything on the bike was scratched, bent or otherwise mangled. The only things not tore up were the engine and the frame. I put on new wheels, swingarm, forks, exhaust and fairings. I got lucky and found all the parts cheap. I checked the valves while it was apart. I only adjusted three valves and only to the next size. You could tell this bike was treated like shit all its life and it had 78K miles. I'd be shocked if the valves were checked before me.

I'm so disappointed that I'm the only one that has pressed what are valves so far.

this is interesting hopefully we get a lot more input to get a clearer picture. It is amazing to me how the prevailing wisdom is so at odds with the manufacturers recommended schedule.
