What's the difference between a 1979 & 1980 muffler for a CR 125 ?
As in what physical differences are their in length & fitment
-
About 12 months ;D

I will be home later to take the pics .
You could also email someone like Scott Steger, he would know. Like I said they are the same though.

1980 Model is part number 18330-466-007

I looked up some websites last night and came up with those part No's too.
Interesting that they use the same sketch on those part diagrams for both years. Wondering if they use generic type sketchs for those parts sketches or is it because the parts are similar.
Different part no's doesn't rule them as different as one might simply be 1mm longer than the other.
I've been caught out before by jigging from parts that unbeknowing to me weren't quite right and also from guys that unbeknowing to them were sold parts that had been made to fit or were from different models.
Just trying to get to the bottom of this.
Any other second opinions?
The 79 is side port & the 80 is centreport, right??
-
Yes Geoff 80 went centre port. I dont know about the 125's but on the 250's they are a bit different but interchangable.I have several -different lengths and some have an extra bracket.
not much help I know.

As you can see in the photo's, they have two very different styles of pipes, the '79 has a very short expansion chamber with a Long muffler pipe (The join is right at the tip of the kick starter) and the '80 model has a longer expansion chamber and a shorter muffler pipe.

Well I'm a dickhead :-[
They are different. I thought they were the same as I always mounted it to your pipe and not a stocker.That's where I stuffed up. I'm really sorry Geoff. The better one is the '80 one.

nice bikes by the way !!!!!!

Thanks guys, that sort of clears it up.
It's just that, well if it was an 80 model muffler that you sent me to jig from Brad, and you had it fitted to a 79 that had one of my pipes, then does that mean my 79 pipe is NQR.
My 79 pipe appears to have a longer stinger tube than the 79 pictured above.
Does this mean that the bike I jigged from may not have had a standard muffler, I jigged it so many years ago now I can't remember.

All I can tell you is that you already had the jig for both the pipe and muffler. The muffler I had on my bike was off a late model bike so was made to fit. It seems that someone else has given you an incorrect muffler so you have made the two fit ???
As one complimented the other, I had no issues as being a package, they fit. Sell him a pipe too!

As near as I can tell, I jigged the pipe in 04 or 05 and I jigged the muffler in 07.
Too much time has passed to remember what muffler was on the bike when I jigged the pipe but it must have had an 80 muffler fitted.
Not to worry, it's not the first time this sort of thing has happened and I guess it won't be the last.
Obviously this model is not one of my big sellers otherwise this problem would have surfaced earlier.
Thanks all for your help.
