adjusted valves and changed spark plug

[old geezer]

Well today I worked on my P 250S. I adjusted the valves. They were a little tight. Around .002. I set them on a tight .004. The original spark plug was in it so I put in an NGK iridium. The gap on the orginal was set at .035. The book calls for .027. I had emailed NGK about the gap on the iridium plug for my application and they said to put it at .027 as well.

It had not been starting right up and the idle was not the greatest. Now it starts right up and idles great.

The valves are not the easiest to get to but a lot of money was saved by doing the job myself.

Glad to hear it Scoot. It's soooo much better to do it yourself. You KNOW what was done.

I did the same a few months ago.  I enjoyed learning how to adjust the valves myself and the engine has run great for quite a few miles now.

Well I have been turning wrenches for over 50 years but the problem is I've got old and lost a step or 2 and Kymco don't make things easy to get to.

I must have saved thousands over the years doing all my own mechanic work. I wonder where the heck it went to???

I'm a desk jockey (Electrical Engineer) and enjoy using my hands and seeing if I can do anything really valuable!

[old geezer]

Yeah, I was a process engineer for General Electric back in the 70s.

[slugrocket rob]

yes, It feels great to do it yourself!!!

[gregspeople250]

Mistakes can be costly, so I just take my time and be sure things are torqued correctly.

Engineers eh! I would love to get a group together one day for cocktails. The catch is... They would have to service anything they designed before they get a drink. It is real easy for an engineer to forget that things need to be repaired, and putting the spark plug behind a compressor, under the front tire well does not get it.

We put it there because time studies show it saves our company time assembling the product.  The COMPANY doesn't care about the life of technicians, only the profits made!  LOL
Actually, I'm not a machine design engineer.  I consult in the thermal solutions world to OE manufacturers.

How do we fix Global Warming Mr. smart guy engineer?  Just messing w/ you.
I MOSTLY build/rebuild boats. I have found every company has the same motivation. $$$$$$$. Screw the new owner/techs.
That must be why I am always broke. Money doesn't float my boat. Water does.

[gregspeople250]

Boats sound like a very fun obsession!
My obsession is engineering racing cars.  I like the varieties that go left and right and have to use their brakes to slow for several corners per lap.  This is an expensive  pursuit as well and it floats my personal boat.

[zombie]

COOL! Same "boat" different road... If I can gain 2-3 seconds anywhere it is a MAJOR accomplishment. It's always fun doing what can't be done.

[gregspeople250]

Zombie,
Agreed, +1!

Now that I know how to get the plastic off this job will be much easier. (P S 250).  I have done it twice with plastic on - both times the setting were very close to what they were supposed to be, if not right on.  Definitely not a job to be rushed on.
