My FJR kid just changed his for the second time. The problem is that he has 40k miles on it. Last changed at 8k miles. Gap was supposed to be .032 (max) and was actually .042. (must take after his mother I guess) He said it was running smoother. :rolleyes:

Mine actually were spot on out of the box. My bike has 12000 miles, so I figured the manual says 12000, then I'll get them again when I have to do the valve clearance...

it's not too bad getting to the plugs.

I drilled a hole in my left side fairing so i can get the tank lifted without taking that cover off. oh the benefits of a 98,000 mile bike that's been rallied all over the country.
Do you have a photo of that jiffy little modification? Sounds perfect for us high mileage, high off-road-use riders who need “function over form” so much more than anticipated :) .

Did mine Saturday, first time lifting tank and removing air filter etc. Thought it easier than most other bikes I’ve done, bar the GS and Pan of course. At 12k I really can’t see any need to change them. The gaps were just over the 0.9mm max quoted in manual. So I just cleaned them closed them down to 0.8mm and put them back. What did surprise me was how dirty the air filter was, no way was that going to 24k as per the manual. Bikes running a bit smoother, but I did throttle sync too, so no way of knowing.E05BF1F2-D1F5-41C1-A621-FE6A3D1F01AE.jpeg

i'll try to get a pic. all i did was line up by eye where the tank bolt was and drill a 3/8" hole. did it with the panel on the bike. just kinda line it up from the top then from the front and go. if you mess up on the first hole you just save more weight.
