@Calum I thought so, I was just looking it up on ebay;
I spotted this MX on the web with an RS pipe fitted to it and the dude reckons it adds 9Bhp to the 122 lump!!!

A good pipe will make or break a two stroke.
Pipes have such a varied affect.
I won't rule it out, although 9 is extreme!
You can get 9 BHP more, but the Power Curve would be like J (Nothing nothing Nothing ohh power change).
Or get a pipe where it's powerband is more well rounded.
A wrap around exhaust is a huge compromise in performance. It's designed for clearance, not performance in mind. And underslung really releases that last part of the performance, at the expense of clearance.
But it's a stylistic choice that not everyone wants. I like it, it suits me as I dont' do, or plan on doing, offroading.

on my dtx i have romeu inox pipe too. i guess here in portugal, he is the best making them for dtr/x

@Calum That's a Jollymoto pipe, which is very similar to Romeu's own version. It is a very unique look for-sure, the RS pipe tucks under pretty nicely tho, so it's not a total eyesore. This may be a future mod for my MX, along with other planned upgrades. The owner had other mods on it, here's his gibberish;
"my 41 bhp mx 125 its been tuned by 55cctuning.com they have dun all the dyno work all the tuning the beggest power mod was the jollymoto pipe off a rs 125 it gave it 9 bhp just from the pipe it was 26 bhp when i got it.the pipe made it 35 hp then i got 34 carb- racing piston-racing reeds-twinair air fliter-bigger jets that gave it 6 bhp its very fast for a 125 it run 14.flat at york dragway with a 4.9 0/60"

Meanwhile on this project...
I have been enjoying the Athena kit so much I thought it would benefit from a mild port.
Off to Mick (who seemingly loves to chat about smokers on company time ) with the requirements.
In this instance I specifically didn't want the exhaust port raised, in essence the Athena kits power deliver is precisely where I want it. But the transfers, exhaust and powervalve did want a touch up.
Since the exhaust port wasn't raised I didn't need any work done to the head.
New piston, rings and gaskets ordered and I will endeavour to smash this on once that arrives, PJME said they are awaiting restock towards the end of this month.
All in all looks like a good job, but this is a VERY mild port for good reason. I have the RS for that screaming power delivery and I just didn't quite enjoy the peaky power of the ported 3MB once I had the RS and Cagiva.

Well they had done superbly well...
I knew they need doing eventually. These were 10+ years old when I bought them and this has been my trusty steed for ~10+ years, once daily then stored for 4 years now just a weekend warrior.
Painless process to strip and rebuild and the kits are readily available on eBay.
All cleaned, rebuilt, new oil and refitted.
These are fully adjustable and I must admit, have just been on whatever setting they came with off the MX bike I bought them from. Since this is a road warrior, I've stiffened the suspension up a fair amount. I'll be interested in seeing how this now performs on the road!
The last ride out I did ~70 odd miles, the handling was becoming very poor. So I'm looking forward to the next adventure on it.
