When poeple start restoring bikes like the TM 250 and they are trying to make it look like a factory bike, they need to take more notice of the expansion chambers, the factory pipes don`t look anything like the pipes on the tm`s that are post up on this thread.
That’s because the factory pipes of the day didn’t have any mufflers at all, or any muffler worthwhile mentioning anyway.
It depends on whether the ‘replica’ is going to be ridden or not.
There are not a lot of places where you would get a lot of rides with a straight out pipe.
Most works RH bikes that I’ve seen didn’t have Yamaha tanks fitted.
I see he did this to save weight, it would be interesting to start weighing tanks to see what is really saved.
I have a YZ C tank and it comes in at 1.6 Kg
Any one got a TM tank to weigh?
