Well the muffler angle looks ridiculous, but the pipe doesn't care a jott so it maters not.
You'll find a lower seat devoid of foam will give a better feel. Actually looks quite good.
Don't you look at my accountant.

Oh yeah, behind the sprocket, Bush that seals against the seal has an oring behind it so it doesn't leak down the inner of the Bush. Replace that too.

That is not looking too bad.
BUT . . . . do not start with lean jets and go up. Put in the biggest you have and go down. Running lean will end in tears. It shouldn't run at full throttle with a BIG jet. If it still does then you need to find a bigger jet, and for goodness sake don't compare it to what a FXR uses.
So my TradeMe "Universal 2 Stroke" muffler arrived today.
Initial impressions, I was a little disappointed to realize how large the inlet diameter is. But it was so light compared to the standard RGV150 muffler. I never weighed it but it's easily a KG or more lighter.
So with weight saving also being quite desirable to me, I decided to remake the joining pipe and make the new muffler work. The outside diameter of my joining pipe fitted neatly inside the inlet of the new muffler. A little time with the pipe bender and mig weder at work and new light straight through muffler is fitted.
I cant get over how quiet a 2 stroke is compared to a 4 stroke. The noise restrictions we have at our local track are such that an FXR150 can't have any exhaust much louder than a standard muffler. A straight through muffler as I have just fitted would be booming on an FXR
I got some more tuning runs done after everyone had gone home from work. #115 main still appeared a little lean, and swapped in a #120. I'll try a #125 tomorrow evening. I just want to get the bike in the ball park tuning wise so as not to waste too much expensive Dyno time.
Running it a bit lean will make it crisp on the throttle and even make good power on the dyno. However, the piston will get "crispy" on about lap 3. If you do insist on sneaking "up" on the jet sizes make sure you go past the ideal jet and see the power drop off a bit. That would be the jet I would run on the track for safety.
I wouldn't have bothered changing the muffler inlet pipe. All you need is the correct size restrictor/nozzle on the rear cone outlet and the pipe after that doesn't matter, as long as it stays larger.
Isn't a TS a motocross / enduro engine?
No. Clearly not. That would be a PE or an RM. Weren't you paying attention at Farm school?

MNZ rule 16.2 Engines must be derived from non-competition motorcycles. Motocross, Road Racing, Enduro and Kart motor and transmission parts are not permitted.
There shall be no restriction on the make, type or design of carburettor, ignition, exhaust, piston, cam, valve springs or cooling system except for class eligibility.
The TS was road legal. My one was even road registered at some point as I have ownership papers from an old rego to help get it road legal again if I wanted. If a TF engine is legal under the rules then why is the TS not?
Doesn't ER stand for Enduro Racer?
That's a common misconception Husa. It was really an attempt by the Japanese to capture the Farmer vernacular. But they misspelled it on the seat cover.
It should have been AR. Or ARR.
