    The Seibenrock does look nice but at 1000 Euros ( plus delivery) it's a bit pricey for me.

    Hey, Pommie John, you might want to try some on like this http://www.castleheaders.com.au/ and the engine swap guys always talk about buying kit and chopping and joining cutting to get things to fit it, Diameter might be a problem.

    Thanks.

    I made this for my Honda with mandrel bends from Mac's Mufflers. A single's not too hard to make but the 2:1 might be a challenge.

I bought a load of mandrel bends online and managed to wrap them around the bike.
    thanks to adrenal for number crunching the calculations. It’s come out quite close with 32” headers and 900mm from the collector to the silencer exit.
    I may have to fit a baffle in the exhaust as we have quite strict laws about noise here in Australia. BF81E3AB-EB27-4CCD-9180-6D81E3C56464.jpeg

    It's been a lot longer than I thought it would be with lots of hassles and some jobs done two or three times due to my crap planning!

    I just have to mount to front guard properly ( it catches on the forks as they move up and down), wire in the side stand switch and sort out the fuel pipes and I think it's ready to go on the road.

    ive converted the side stand so it doesn’t flip up automatically. Problem is you can’t see the stand when it’s down, it’s hidden under the left pot. I have put a brake light switch on it which lights up a red led on the dash to warn me the stand is down.

    Aha, think I would have thrown the sidestand and built my own. I know the one on my GS is bloody hopeless.

    Would you be able to post some photos? I have had a number of close calls around my stand down. Just wondering how you got the sensor mounted and what did you do with the light.

    I was going to simply not let you start the bike if on side stand.

    Sure, I'll take some snaps over the weekend.
    I used a Yamaha brake light switch and drilled a couple of holes in the back of the sidestand mount. I bought some LEDs from Jaycar and you just need to find a 12v source and a handy earth point.
    More details later.

    I was chatting to a guy who did a lot of adv riding and his bike has a sidestand switch that disconnected the ignition. He found himself stuck in the middle of nowhere after a rock torn the sidestand switch off and left him with a non running bike. It was an easy fix once he worked out where to look!

    I took it out and ran it up today. I've got a noise meter and it's 108db at the prescribed RPM for Australian road rules. I guess I'm looking for a better muffler now. The seat upholsterer is sick and I'm not sure when I'll get the seat pan back. I might have to line it in high density foam until he's better. DSC01439.jpg DSC01440.jpg

    Sorry but I can't show you the side stand switch without taking the stand off. I may need to do that in the coming weeks but not right now.
