This pipe is fitted to a 79 CR 250 fitted with a 360 mugen kit

Not entirely sure but the pipe looks to be the Mugen pipe.
I reckon the swingarms are by the same manufacturer, just from different batches, from memory the same swingarm fits the 78, 79 & 80 so they could be from different years.
They do look a bit different to a DG swingarm that I saw a few years back though.
-
Thanks Geoff :) your name was suggested as the pipe builder by a previous owner :o I put him straight though >:( I said no way Geoffrey would turn out an amatuer effort like that ;D
You probably right about same Sw arm manufacturer different batches :) what manufacturer though ???
Why are the shock mounts different side to side ???
-
Why are the shock mounts different side to side ???
From memory the swingarm is lopsided for chain clearance.
-
if it is a Mugen pipe look out Bill - very poor welds on the top section under the tank. How do you go about pistons for the 360?
-
Thanks Ross :) Pistons i dont ;D the Mugen is just here for sale on behalf . I wanted to know what i was selling before i advertise it :)
The 250 is mine and i want that gone to :) but would be nice to confirm what is fitted to the bikes before i advertise them .
-
I reckon they are both dg arms
-
Would they have been gold anodized from new ?
-
Both swingarms are repo DG that were reproduced about ten years ago, Genuine gold DG arm has strengthening arch in front of wheel then a gap and rectangler brace before swingarm pivot, the arms pictured have a solid plate top & bottom.
The pipe is a hand made copy, Genuine Mugen pipe is pressed with a seam and looks like a standard 250 pipe but fatter.
Can send picture of Mugen pipe if you please.
-
I have a DG arm here, yours are quite different, so Not DG. No help other than that.
Cheers,

Fatboy, does the red swingarm have holes drilled in it underneath like the silver one?...it was explained to me by my welder that the holes are to let the gas out when they weld to get better penetration and strenght of the weld....they are more than likely recent copies (Novation?) as they didnt do that in the "olden" days....clever bugger arent I...LOL.,,,I'll give you 25 sqids for them. ;D
-
The swingarms do look like DG copies, there's been a few different people making replica arms over the years.
-
Thanks chaps :) next question opinions sought whats the better look for one of these on a red rocket ???
Red same as frame etc
Polished aluminium finish
Gold anodized
Be gentle ;D
-
I prefer the std unpolished alloy finish, like the factory bikes were.

Once a tube is enclosed the heat from further welding increases the pressure inside the tube, that pressure wants to escape and will do so through the weakest point which is the weld pool.
That’s why we put holes in tubes but you only need to have one hole to fix this.
2 holes is for plating and anodizing so the solutions can get in and out as one hole would create a vacuum and stop the solutions running out freely.
Physics hasn’t changed over the decades, they still needed to do this in Ye olden days but they may have been more discreet about it.
If you leave a tube open until all parts are welded to it then you can close it off and not worry to much about the hole but then sometimes pressure build up from heat treating can upset things.
A LOP arm from back in the day…

Christ you can talk some shit ;D

The long baffle cone looks typical of the Mugen pipe specs but it does look like it sits low at the front and hangs below the lower frame rails??
This pipe is fitted to a 79 CR 250 fitted with a 360 mugen kit

Geoff that pipe doesn't look like a genuine mugen one, I had a 360 mugen that fdr now owns and the pipe was quite different in the header like you stated. It was actually fairly similar to the 250 pipe.
-
I vote same as JO raw alloy finish on the swingarm 8)
