The Tlr and Seeley exhaust back boxes are mounted on opposite sides of the bike. Tlr left, Seeley right.
If you are going to fit a WES from a Tlr it will need to flipped from left to right.
It may be easier to modify a DEP system to fit. (and cheaper)
You can also fit a Tlr header pipe to match up with the DEP.
The standard bikes had an auto system fitted. When you put pressure on the kick start the exhaust valve would be opened.
I use a finger operated lever to do the same. Takes a lot of strain from the starter gears, shaft and kicker.
The bike might look good in the photo's but it would not be allowed to enter 'Air cooled mono class' at our National Twinshock series as only minor frame mods allowed!
The Tlr needs a lot of tinkering to get right and the Seeley was spot on straight out of the box.
From new the Seeley was under powered for big trials back in the day so the ultimate
for me would be to put the Tlr250 motor in the Seeley chassis. Sorted.
You will probably need the 50's as the Tlr's tend to sit low at the rear, this also makes the steering head angle even more 'relaxed'
I'm similar weight to you and use 50's.
