Q: Can you increase the capacity i.e. PE175 crank and barrel?

dont know-hijack-back at you !!..did the "N" series come in an 80cc ??
cheers A
ps sweet blue frame you got

[crankpin]

Sure they did an 80N

The blue frame hurt my eyes at first, it's growing on me though

It still hurts my eyes..!

I'd have it powdercoated by now but not sure what I'm doing with it yet???

[JohnnyO]

One of the best 125's in the twinshock class.

[crankpin]

Possibly, but at 16 stone in my gear, do I have any right to be on one?

[JohnnyO]

Ok i'd probably stick to 250/500's... extra weight seems to kill a 125

[crankpin]

Hence the original question 

[JohnnyO]

I'd say a 175 engine would bolt straight in but not sure about the 175 parts fitting the 125 cases.

[crankpin]

Exactly what I thought.

Anyone else tried this mod?

[JohnnyO]

You might have to start a new thread with that question...

In short the distance between studs vary.... Rm 125 N at reed  = 90mm  and the  T  are 68 mm where as the Pe are 72 mm    
There is no way you are going to fit a PE 175 barrel in Rm 125 N/T cases  without a lot of welding and Milling

Hey Stew wouldn't the 125N & T be the same?

[Davey Crocket]

You would think so but there diferent....cases, crank.....probably why you dont see many around...I think the N's closer to the ABC but the T's on its own.
