Damn, two con rods over the course of three slugs? That seems excessive.

Yes wording perhaps? Could be after 8 years he decided to change the rod, so hes on his 2nd?

At 11yrs old my main brg failed do I changed the rod at the same time.

I'd say about 30

However, if the TO uses ES or EG plays no role. I just wonder how his manual says use a BR9. It should read BR8

We cleared up that he should be using the 8 and that the S version is good as well. Maybe it was an early manual misprint or the manual was later revised?

I got some dirt in the engine and had to do a piston and rod at 50 hrs. So I'm currently on the second rod and it got the second piston at that time. Then another piston at 250 hrs which makes the third. I'm at about 375 hours now so I expect to do the piston again at the end of 2019.

Yep, I have read the thread. Sure, could be a an error in the manual, but I doubt it. But no problem, he can run what he wants.

The core thickness has already been mentioned but It's Interesting to see the difference in length of the 2 approved/suggested plugs?
Denso is on the left.

In all my years and many different bikes, I've always used NGK plugs, I wouldn't use any other brand.

I can't comment on Denso or any other brand, maybe they're as good, better or worse, it's just I know and trust NGK. It's my personal preference.

All the best, Dave

I see no difference in length.

Like Dave I only used NGK plugs in 40 years of riding. Possibly others work well too, I'll just never find out...

240hrs due for 4th piston,fouled 1 denso at beginning with stock needle,switched to NEC/NED needle and NGK plugs,havent had a problem since,but usually i change plug @30/35hrs although i ran 1 for the entire life of the piston no probs (for me thats usually@60-80hrs 200)
I do carry a spare on long/solo riding
Different 2t oils seem to vary a bit in how much residue accumulates on plug,and plug colour
