Re: 118,172 Miles on '88 250 Ninja - Maintenance Time        


Thanks for the update. The details of your reports are very helpful.

If I have this right, after the valve adjustment at 1700 miles, it went another 31,200 and only needed slight adjustment. It looks like KHI has very good quality materials in the valve train.

I found a similar situation as motor went from 4,261 miles to 20,534 miles between valve adjustments and I only found one exhaust valve slightly tight. The spark plug gap had widened to .030, somewhat proportional to what you encountered. Impressive motors indeed.

I do have a question. I have never run across a spark plug seized into the threads. Is this more common than I've come to expect?

Thanks again for sharing your experience and experiences with us.
