Thanks for leading us around Wallaroo on Sunday
Just thought I'd pass on my thoughts for similar bike in same terrain.
My gearing is 13/48, perfect in the single track but on the way back to Medowie it was frustrating on the open fire roads.
I have had TSP do the head, the jetting is what the guys at Cessnock M/C would have done back in the day and runs great.

No worries , we did have to wait a bit ,but sometimes you get that .
I don't know if your ever going to fix that open firetrail speed as I think its the pay off of a smaller bore that's excellent in the singletrail . The 200 I like as those singles is what I like riding and when im on the more open firetrail im just sucking the big ones in cause im to out of knick from the singles lol and not going fast

The expansion chamber finally arrived today so will test her out on Sunday FMF gold series.
Had a suggestion on cutting down the original pipe and making it a bit shorter instead of buying another one , anyone tried this ?

The shorter pipe makes the midrange hit harder, I replaced my FMF shorty with the standard pipe and was much happier.

I had a 250 exc and a 250 sx there at one stage and with that bought a procircuit pipe for the sx so I tried all the different pipe combos/chamber combos with the EXC . The shorty was the worst pipe to have on it cause it just made it to Snappy for my liking the best combo on the exc was actually the stanadard pipe / procircuit chamber off the SX ,It had power but still smooth.
I don't want cut it down to a shorty length but to the length of the standard 200 sx pipe size or the dep pipe I have that fits the mx pipe I got (its far from a shorty just sticks out past the number plate

The major back-pressure difference between FMF and OEM is in the bore, not the length. You can only compare tuned-lengths of mufflers with the same core diameter (and these two vary). FMF use a much bigger bore than OEM.

Cut the OEM muffler back to 15mm from the plastic cradle. Free mod and it picks up a bit of midrange without making any more noise.

Huskybloke, I did what Nutty suggests. It works well and as described.

Here is a pic of the cut back 200 muffler (bottom one) a 2018 XC250 standard muffler for comparison ( middle one) FYI the XC has a shorter muffler than the EXC (same as standard SX I think)
The top one is a Leo Vance muffler which I have been running on the 200, same core size as the standard 200 muffler.

If you want the cut back one and are prepared to pay the postage you can have it.

I had a 200 way back when (2002 model). The hot combo then was 14/47 gearing, a pro circuit chamber and a shortened stock muffler (they were hockey sticks back then). That's how mine was setup and it went really well.

I do remember that the shortening of the muffler worked really well. It came onto the pipe earlier and with more authority and still revved out OK

so this what the old one looked like on the bike




so I just drilled the old pop rivets out took the end cap off measured the length I wanted , I just used a grinder with a cutting blade onit



after I cut that and just used a knife to cut through the packing I undid the front bolts on the pipe and pulled the core out and measured up what I had to take off as it is recessed in a bit to take the endcap





after that I just put everything back together measured the holes up for the endcap drilled them , I used stainless steel pop rivets







whacked her back on the bike



End result , it cost me $6 for pop rivets
