Best value exhaust pipes

Wow! I never noticed that some 235xxx where 850s!


Also interesting is that I have 300xxx 850s with dates before the one you caught which in a way verifies your statement about 235xxx being built out of sequence.

Yes, and the odd '235xxx' 850s appear to have been 850 Mk2/2As so were certainly out of sequence with the usual 850 3xxxxx series numbers.

I have purchased 2 sets of Les Harris pipes for my 74 850 and both sets on the left side did not fit properly at all.Finally went to an Emgo set and right out of the box fit perfectly.Very satisfied

We should get together. I have a nearly new set of unknown origin where the right side is kicked out too far. These have been hanging in the garage for about a decade or more. I tried them on once and said nope.
 
What is the consensus on the best source for the emgo pipes?

Any respectable vendor can get them.Just make sure you specify Emgo. I had a bad experience with the Bonneville Shop but that could be a fluke.

Planning to buy a pair of unbalanced roadster pipes for my ‘73 750.

I know this topic has been discussed, but variations in supply might make a current rehash worthwhile.

I’m in the US and considering the LE Harris pipes over Emgo; any opinions or other options?

Thanks

I had just purchased a set of LE Harris pipes for my Commando from the Bonneville shop. I had to send them back because once they heat it up, they started forming little spiderweb crazing throughout the heat area. The Bonneville Shop sent me another pair and they are doing the same thing. Apparently it’s an issue with chrome and restrictions in the UK. Go for the EMGO. I’ve had good luck with them in the past. I was told I could send the second pair back to the Bonneville shop, but it would be at my expense and I’m already losing money on this issue. Decided to keep the pipes until I buy another pair somewhere else. Good luck.
 
Emgo it is. I placed an order with CBS and paid a bit extra for quicker shipping; they left Lancaster Thursday afternoon and are passing through San Jose this morning…probably arrive in SF Monday. Will report back.

Interesting thread diversion about 235
serial numbers; some nice detective work there! My bike’s data plate reads 2/73 production date.

Thanks to all for your input. As with vintage guitars/amps and special interest cars, half the enjoyment is sharing the experience, and this forum certainly does that!

Why not send me all your bike info so I can post it?

Let us know about the kick start lever clearance to the right muffler. I have not come across any aftermarket pipes that are correctly bent to allow the 750 type kick lever to be used. Everyone has had to use the 850 MkIII lever.

OEM pipes/mufflers hit just as bad!
 
I don't remember this being a problem back in the 70's on my 73 Mk1 850.

Dave,
The Emgo pipes that I have installed clear both the side stand pivot and the stock kick arm. I was very pleased.

Just get a stepped mounting plate. Not only does it provide more clearance, it looks better (stepped plate on the left, stock on the right)

There is definitely an opportunity for a supplier to make exhaust pipes that are to original spec.

Agreed,

I have a set of original 1970 Roadster pipes which are a different bend to later types, and exit the head at a more tucked in angle.
No idea if they offer better kickstart clearance as they're parked awaiting re-chroming.
I believe the original Production Racer pipes were similar - but not the same numbers.
I had a conversation with a 'Leading Norton Parts Manufacturer' somewhere in Central England who listed various pipes under the correct part numbers, but admitted that whatever was ordered I'd just get a air of later type Roadster pipes...

This famous photo shows the early pipes.

 
Emgo pipes arrived Sunday Thank you, USPS!)

Beautiful chrome, smooth kink-free bends, solid and substantial flanges.

Left side fits perfectly, right side kicks out about an inch at the end when parallel with the left side.

Spoke with the vendor (easily reached by phone and very friendly); some discussion about possible fit variations due to isolastics, and offered either refund or exchange for another set, but no guarantee of better fit. An honorable response, and will continue to order from them on other items.

Given the idiosyncratic manufacturing nature if these machines, I’m inclined to accept that ‘adjustment’ is inevitable and will tweak as needed, hoping that the excellent chrome holds up to a little gradual persuasion. If I get it right, it looks like the kick start will clear.

Thanks again to all for the helpful posts!

Marc. Tighten the head nut while pushing the pipe in towards the frame with your foot. It will "tweak" it enough to clear the kicker. Or, before tightening the exhaust nut tie a tie-rap around the muffler end of pipe and the frame bottom loop. Then tighten the nut. The problem with tightening the right side is when you tighten the nut it twists the pipe out from the frame. The left side moves the pipe in towards the frame.

With my Steve Maney style pipe I had to use a small block of wood to act as a lever on the timing side to keep the orientation correct while initially tightening the exhaust rose.
