CSMNL Exhaust for CB550 K3

<< < (2/7) > >>

Seabeowner:
If they are like the originals I remember you have to fit the pipes for 2&3 first. They are the ones with the two threaded studs. Fit them to the bracket and hang them. Do not tighten everything too much at this stage. Then the pipes for 1 & 4 which have one threaded stud and one plain stud can be hanged and fitted into bracket. Then move to your satisfaction and tighten the lot.
They were much easier that the four pipes on the earlier 500/550s.
Or if you bought the earlier pipes then ignore all that. They may be tricky to fit a K3.

Hi Nige, has the pipes not got the stamping on them stating iL and oR etc? Mine were a number of years ago but they were a bitch to fit. I used ratchet straps so they would eventually fit. I believe they were a prototype set I think that were pre - production. There were quite a number of years they were no longer being produced.

Hi Johnny & Seabeowner & Ted

Yes I have since had a look and have found the ones marked A & B on the boxes ( I which I take are L/H 1 & 2 ) do have the following code stamped on them of L1 & SL only trial fitted so far and S1 seems to be very close but L1 miles away more tea needs and some deeper investigation I think , Might get the C & D and just see if they fit better as I had to have some welding done to the frame on the L/H side just fwd of the swing arm area which might a have effect on exhausts 1&2 ?????

Ted has suggested the same to fit 2&3 first then hang 1&4 slave together loosely then tight up when happy
will have a look later this week as Sheila is hinting I need to fit some acoustic panels that are lying on the living room floor at the moment 😂 so you can guess which order the jobs will be in 😂😂😂😂

Thank you for all your help on this so far guys

Rozabikes Tim:
Are the acoustic panels for when you fire the 550 up?🤔😳🙃

McCabe-Thiele (Ted):
I'm assuming you can identify pipe 2 from the position of the bracket on the silencer section.
What is the situation when you just try to fit the pipe for cylinder 2 ?
Is it that you aren't sure if you are using the right bracket ?

Using a bungee strap at the end of the silencer attached to the frame can help you get the first pipe in place, be it no2 or no3.

Are you sure you removed the old front pipe seal rings from the cylinder head exhaust ports ?
