Well I don't know about Kiwi land but when I tried this with my OEM muffler - on which there was no sign of Supertrapp branding - I came to a stop quite quickly.

After the end cap there's a "soup plate" spot welded, when i tore it off there was some kind of perforated net on the sides but no discs at all!

I think we Europeans didn't get the Supercrapp stuff.

BTW Mine is 2001!

And one of the inside of the exhaust with the cap removed.

So, what did you do with your exhaust if you can't core it?

Yup, that's the noncoreable bastard one.

I changed it for a SXC one with an S pipe without the cat.....

Crisis, we have the EU/AU muffler as makazica shows. Only the yanks get the supertrapp. 'swhy I bought meat popsicle's OEM exhaust. But be thankful because the supertrapp is 1.2kg heavier.

Ta Colin, I read in the thread that you had modified yours and assumed that meant mine was modifyable...I should have asked you first! Currently chasing down an SXF muffler from Hamilton which I hope will solve my problem.

Thanks to everyone else for the input, very much appreciated, if you can get to NZ for friday night the beers on me!

Many questions and problems

I bought a 03 640 Adventure and needing to fix the whole starting/running problems.

1. it will not start when cold unless I have the manual decompression pulled or I just need to kick it over. To me it sounds like the cam auto decompression is not working? And how hard is it replace cam or is there another fix to this problem?

2. I let it sit for about a week and a half since last ride and now it would not start at all and once a jumped it I was able to but if I give it any fuel it dies? No idea what this maybe, choke seems to not make much of a difference. But there is plenty of play in the choke cable.

3. The PO removed the snorkel and cut the top of the box. Is it needed to replace the box and snorkel?

4. I also have a far bit of oil coming out the base gasket, does it require removing the motor to fix?

I also live 7000' so jetting is something that I need to figure out.

It seems that there are way more problems with this bike then I was lead on to believe and wondering if i should have just stayed with my old trusty DR, miss the DR but love the KTM suspension. Any help would be greatly appreciated... Or just get another DR and install the suspension on it and sell the rest of the KTM parts?

This is the riding season and hate being down for it...

Pull the carb and clean it, set the float level, check the needle for wear, note the jet sizes.

The base gasket shouldn't leak, how many miles?
Has the engine been apart?
You can change the base gasket with the engine in the frame.

Do you need a new battery?

Well I tore it apart yesterday and it looks like the rocker cover near the water pump is leaking. And as to the carb the PO had a 162.5 main in there and the needle at 4th position, so being at 7000' I installed a 152.5 main and put the clip in 3rd position. I also cut and opened up the the stoke exhaust.

I'm still not sure about the removed snorkel and cut air box. Also anybody have any idea about that auto decop, is it possible to just replace the spring?

fine carb tuning with loaded's adjustment screw

if you can adjust the screw while the engine is hot, here is creeper's guidance:

It doesn't have to be 2.25... it can be 2, it can be 1.75... it just has to be somewhere that's a known value.
2 is good (for 4th grade fraction dropouts) because 3 full turns out is as far as you can go rich before the needle is fully off it's seat and you're not accomplishing anything anymore... and if you go less than 1 full turn in, that's an indication that your pilot circuit is on the fat side.

All your looking for is a clean, crisp throttle response. Typically, when you find the place where the idle speed is it's highest, that's an indication of a good air/fuel ratio... and throttle response should be right there too.
Somewhere between 1 turn and 3 turns... and preferably between 1.5 turns and 2.5 turns. If you're right there, then your pilot circuit jetting is right on the money.

The trick is not to spend 10 minutes doing it... you're mo-sickle ain't getting any cooler sitting there idling.

Once you got the scha-wing... set the idle speed and go fer a ride.

entiende, mi amigo?
