Title: It Must Be About Time for Another Plug Replacement
Post by Digger on 02/08/09 at 19:28:11

I've just been thinkin' it's about time I tear the head cover off of my Savage and re-torque the head bolts (I do this every 4000 miles whether it needs it or not).

Well, went for a little toot today, and, when I put the bike back in the garage, noticed a tell-tale light oil spray on the battery box.

Yep, it's about time I tend to that plug (again).

You are looking at the aft-starboard portion of the cylinder head.

BTW, can someone please confirm that the P/N for the better of the two available plugs is 11145-41B01? The last time I replaced this plug, I stupidly ordered P/N 11145-37401, which was the old style plug with the cupped shape.

I remember reading this forum back then, and somehow getting the impression that 11145-37401 was the new style plug. Well, it wasn't. :-[

TIA!

You're a better man than I. I did mine at 7,000 miles, though there was no leak, and everything was in spec. It will be at least another 7,000 before I even think about it, unless I start to see some oil. It's doable; but for me, it's a PIA. Of course at my level of mechanical ability, an oil change and a valve adjust is a major wrench job. :D

However, it takes me about 2 1/2 years to log those 4000 miles. I average about 25,000 motorcycle miles a year (I don't own a cage), but only about 1500 of those are on my Savage.

Ah, I see. I've had mine since May, and have about 7500 on the odometer. Own 1 cage, but it's primarily the wife's car. I only use it in bad weather.

& Ive never retorqued the head. I was gonna when I did the cam chain, but was nearly done puptting it back together when I remembered. Next time I start in on anything with intentions of doing more than 1 thing, I will make a note. Well, IF I remember I will..

The new plug is supposed to be better.

Of course it still leaks.

I'm opting for an aluminum plug with hi temp o-ring. with any luck, I will be able to make it low profile enough to pop it out and replace the o-ring if it leaks w/o having to take off the cover.

Where are you going to get the metal plug? I am facing this and would like to put in the best thing I can.

The 1st one I'll have made (it's great to work where things are made)
Then I'll try myself, or get a small batch professionally run.

You obviously live a cleaner life than I do. If I were to tempt the gods in such a fashion I'd have blown a head gasket long ago!

I think it is odd that Suzuki, known for making high-performance motorcycles, designed an engine that requires the head bolts to be re-torqued. It isn't something new, as my 1983 Suzuki Tempter also required head bolt retorquing. It, too, required removal of the head cover to do the job. The Savage is worse, because in some cases it is said to require removal of the engine to get the cover off. Anybody ever retorque the head bolts on a Briggs & Stratton engine?

Guess it could be worse. It is said that valve adjustment is a $900 shop charge for a Harley V-rod, because it also requires removing the engine from the frame for access.

Make sure it's a tight fit. And maybe make it for 2 o-rings. The one I had made by my machinist friend was a bit loose. It used one fat o-ring. After around 4K miles, the o-ring started to let oil by. It looks like the o-ring started to flatten out. It was a medium high temp o-ring. I think it may not have liked being so close to the exhaust port........ Maybe you should do a temp reading on the area so you know what temp o-ring to buy.

Also, the plug opening on my '01 head was cut deeper than the '87 head I got (to fix bad cam journal on th e'01)

I replaced the metal plug with the new style plug but added a spring to to the top to have it pushed down. 2 K miles no leaks......

T,

Interesting idea, I just might have to try that! [smiley=thumbsup.gif]
