Title: DR650 exhaust
Post by mark61120 on 01/20/20 at 06:36:24

I know (from reading various posts), that most DR 650 parts will not fit the LS650, but will the exhaust header?
Thanks,
Mark

Nope......the DR650 head has the exhaust port on the left side of the head, the exhaust port on the Savage is on the right side.

Yes, I know that.
I want to know if it fits and try a different routing.

Only the newer DR650SE as the exhaust port on the left. the older DR650S (early 90's) is on the right , It has some wild bends and I have no idea of the size or fit to a Savage. It doesn't appear that you can by one new from a dealer ,and finding one in good condition used may prove impossible , I'd have a shop make you a custom pipe .(all shining and no dents)

I can buy a new stainless on for a very good price. I just need to know if the flange will fit the exhaust post.

I have no idea , but even if the pipe was the right size and the flange bolts up ,You would still end up having to bend the pipe,the cylinder on the Savage is upright and the DR cylinder leans forward, and you want to be sure the pipe was no larger than 1.5"-ID

Im going to try one if a few months. If you havent done anything by then Ill let you know.

Im of the mind that you could rotate it and find a usable angle.

Exactly Spammy! As long as the flange is the right size.

Have you tried heading to a dr650 forum and asking someone to grab a measurement?

Title: Re: DR650 exhaust

DDR riders must belong to a secret society. I joined the group and posted my request...Not one person has responded with any flange or port dimensions for me!

Thats been my experience with most forums. If anything requires a person to get off of their computer chair it aint gonna happen. Opinions are quick to come in, but a simple measurement, pfft.

This site is lucky to have a bunch of good forum posters. Very helpfully usually.

I tried a 90's DR650 some years back and it did not fit.
The bend in the pipe was too tight and the flange/pipe did not either.

Good to know Lancer. Thank you.

Actually Lancer, can you remember what year the exhaust was from, as they changed the design in 1996.

Instead of cobbling together an exhaust that was not designed to fit the bike, why not take the OEM flange and have a custom exhaust mandrill bent just as you want it? What are you looking from an alternative exhaust that you aren’t getting from the OEM pipe?

Because I can pick up a s/s dr exhaust fo £49 and it would cost over £250 to have one made.

Sounds like a great deal...if you had a DR650.

Title: Re: DR650 exhaust

Or if the dr exhausts fits the Savage, which is what I am trying to ascertain!
This is an exhaust I have had previously made. It was, as I said around £250. It would be nice to save a bit of money where possible as I cusomise this next one.

It was from the early model, not the ‘96 +

Probably worth every penny too. But why not save $200 if you can. I get it.

Very nice build. Is that a Yamaha tank on there? Looks like it could be off of a xs400. I like the way you "countered" the tank line with the seat line. The "norm" is to go for a straight line. Looks like you made really good lemonade with a lemon. Nice.

Or if you can't find a shop that can bend the pipe for you, something like this is the next option.

That one piece has every bend that you need for about any exhaust design. Cut and weld to whatever your needs are and weld on the flange.

Ohiomoto. It is a Yam tank, SR400. I had to modify the tunnel a bit and move the front frame mounts for the tank, but nothing too serious.

Looks great! What was involved in modifying the tunnel? Persuading with a big hammer? Welding in a new tunnel? Details, please! I love the way this tank looks.

Post by mark61120 on 01/27/20 at 02:17:15

Edub, Yes, a big hammer and a blow torch!
Also, it needed a new fuel tap, and as I already had an Triumph tap sitting around, I made a plate to fit that and mount onto the tank (as the screw hols are all wrong for the tap).
AS the tank is from an oil-in-frame (which is what was needed to hide the electronics), it left a larg gap at the front of the tank when mounted. I kne I didn't want the speedo mounted on the top yoke, so I made a bracket out of aluminium and leather to match the seat. This was attached to three strips of steel welded into the tunnel of the tank.
If you are interested, the switches fitted into the riser holes are from my first car, a 1953 Austin A35!
