Exhaust question?

I recently swapped a battered Peugeot Ctech for a rieju mrx, the exhaust i got with it is a cheap MK pipe that is mounted with springs and full of holes. in my garage i have the MK pipe from my old derbi that was held on with bolts and is in much better condition can i make this fit or do i need a spring mounted exhaust?

 

when you say MOUNTED with springs....do you mean its joined together with springs or the mounting fixings are flexible?

If the sections are joined with springs its simply for ease of removal. If they're for flexible mounting then you'd need to do the same to any replacement to stop it cracking when mounted

 

the exhaust is held on by a spring on either side at the barrel?
i dont really know how to explain but thanks for trying

 

ah, you mean into a collar thats bolted to the head, a bit like allspeeds....

it'd be OK to fix a ridgid pipe but you're best securing the other end with a rubber flexi-bolt. The engine will vibrate through the frame. if you dont and could end up cracking either the exhaust or worse still, the frame

 

no it wont crack the frame ...many exhausts are spring or solid bolt and for the same bike as long as it fits and it matches the cylinder it will be fine

 

Have seen cracked frames where the exhaust and everything else is solid bolted. The stresses have to go somewhere..........

 

but the exhaust is mounted to the engine and the engine moves on buches ...i dont get how the frame could crack

explain please

 

it the engine can move in the frame on bushes and the far end of the exhaust is fixed solid to the frame then theres movement back and forth/side to side. Either the fixed point will break or what its bolted to

 

well i supose its different for that bike then becos aerox is mounted to the waterpump cove and dosent touch the frame at all

 

i have only ever seen a frame crack on a chinky pit bike

usialy its only the exhaust get some serious cracking due to stress as its the weakest part being made of like 2mm thick metal

mount the exhaust with a rubber bush inbetween the zorst and the frame like most bikes come out of the factory with it will absorb the vibrations

 

where can i find one of these elsewhere online, including shipping is like £50 for a £17 part!

so can i take the things that the springs hang on to somehow?

 

have you got a pic of wat you mean ...do you mean were it joins at the manifold ??

 

i will take a picture tomorrow but the barrel is made with two little holes that the springs hook on to but the exhaust from my derbi is held on with a bolt on either side of the exhaust (where the current exhaust has hooks for the springs) can this exhaust go onto this bike?

 

does the bit with 2 holes on come off ...if so just take the old one off and swap them over

 

it is a part of the barrel, but can the other exhaust be fitted anyway with some kind of adaptation?

 

cant you make it fit


ie cut the bolt bits off and weld a small hoop on the exhaust ...but i dont know if there is such thing ...what barrel is it so i can have a look

 

the one that comes as standard on a rieju smx i know its a minarelli engine if thats what you mean

 

rite iv had a look and it is a weird barrel isnt it lol...

but you could just cut the bolt on bits off and put weld 2 hoops on it ...but i think the width would be too small ...its a bit of a bodge i know but in theory it should work...if it is wider nuff
