Which one would be a better deal in your opinion? Btw, my bike's a 400cc LC4, 2002, which I am planning on modding the engine to 512cc or 658cc during the next piston exchange/check, which is in 10000km (a year).

I would go for a Keihin.

I searched the whole internet and found your thread from 2004.

Nice thread and some good alternatives but it doesn't have any discussion on mounting the Stebel Compact Nautilus

Still looking.

The torque spec for the four long bolts that sit over the rocker bearings is listed as 20 nm (15ft.lb). The right side torqued up fine, but I snapped the left rear off as I was approaching the 20 nm spec. It snapped lower than flush and it was a full 2 hours to drill and extract it with no damage to the internal threads. Whew!!! Creeper's bike was a 2003 and his torque specs were much lighter, showing just 6ft. lbs on the longer bolts.
I found some max torque specs online for 6mm bolts and they were showing just 12ft. lbs for a 12.9 grade bolt. Something here isn't adding up and I would appreciate any information available from the collective.

Thanks
Bob
I just did the same thing on mine, even after reading this and going with gunnerbucks revised specs, one (12.9) didn't even go the the 6ft/lbs before it sheared! I guess too many times following the FSM, over stressed it! Now I'm thinking I should replace all the rocker bolts, great just what I need more holdups and parts to order! I'm already going buggy having my bike down!

I think the Keihin's off from a Honda CRF 450. It's not listed on Keihin's website, so unless the jets and all of those are the same, finding parts and stuff could be difficult. I don't know about the FCR 40. I found a few FCR 39's and 41's on ebay as well so I guess I'll have to think which to choose...

If I remember correctly the Honda FCR's are different on the intake side than the KTM's. Look for one off of a 450, 520, or 530.

Page one of this thread, Part Deux, section 3 is a link to that thread. You can find such things by using your browser's page search function (usually Ctrl-F).

But I think you're right and nobody has posted specifically about this horn on this bike - you'll be the first!

Yup, I missed it several times.

I looked for space for the stebel horn under the fairing and to either side and there isn't enough room to mount the compressor cylinder vertically as an assembled unit (as supplied). The horn does come off the compressor giving me more options and problems to solve.

The Hella Supertones are mighty loud, and mount easily with the included bracket, although my brackets began failing after few years so you need to check them occasionally.

There are two versions of the Hellas - one made in the EU and another made in India. Not sure if you can still get the EU version (check with Susquehanna Motorsports) but folks said they had better sound.

As with the headlights you should consider a wiring kit to improve the voltage fed to them. Eastern Beaver in Japan makes great kits. I did and while I can't comment on the change in output I can say the kits have been tough enough to save a horn from being lost when the bracket broke just by the tightness of the terminal connectors and the stoutness of the wiring.

Skibum, you are just right! I remember KTM's Users Manual specifies it must be used only for an emergency. Sounds like it's not as innocuous as the standard key method.

Cockpit Mod-Throttle Grip-Choke Lever

Hello everyone,
I'm modifying my '01 ADV cockpit and controls to a more "rallye" style version, and have a problem that I need advice:
I want to replace the stock Start/Stop switch that is integrated in the throttle can, by my '03 EXC 400 witch I managed.But I now want to replace the stock throttle grip for a smaller one! Does anybody knows if the EXC throtle cables+throttle grip will fit the ADV (lenght wise)?
Any suggestion?

Also in the other side, I've replaced the stock switch assy by the EXC smaller one, but I have the problem of the choke lever that is originally part of the stock switch. Any suggestion on how to make/adapt an alternate lever? I have some ideas, but I was looking for some more!

Looking frward for some tips!

I also have the 400LC4e and would really like to know how you plan to do the cc increase. Can it be done with only top end parts? If crank and rod must be replaced, it can become very expensive. Do tell more.

I plan on increasing the diameter of the cylinder from 95mm to 101mm. I'll also replate the cylinder. The cylinder head will also be machined. I haven't made up my mind whether or not I'll increase the valve diameter size or not. I'll decide on that later.

Machining the cylinder and replating it will cost around 280€, machining the cylinder head I would estimate at around 200€. Then I'd buy a W๖ssner 100.94mm forged piston for 215€ from ktmax.de. I haven't decided what to do with gaskets yet, I'd probably have to order some specially manufactured or then modify from the originals... Don't know yet, still planning. I'm thinking that I would want to max the price of the rebuild at 800€.

With these mods the stroke will remain the same and there would be no need to change the crank and rod. Also, these machines use the same bearings at the bottom end, so I'm more than sure that they would last. I guess I would change the bearings for the bottom end while I'm at it if they look like they'd have to be changed. It doesn't seem very expensive, but then I would have to adjust the valves and the jetting probably in a dyno or then install a lambda sensor on the exhaust to get the jetting spot on.

My biggest worry is though that the yearly vehicle inspection will get transferred to motorbikes from cars as well, so I can't keep it in plates since the emissions would increase. It's a little law thing they're talking about here in Finland...

Thanks Lortdadu. That really is more work than I am willing to do. I need to check all the part #s and see if any model displacements share the same crank and rod as the 400. From there it may be possible to just swap top ends. The whole idea is way down the road for me as my 400 only has about 7500 miles on it.

One method works for sure. The DR650 came with the BST carb as well but only uses a short knob, you can buy them off fleabay. The problem with this is the choke is now hidden under the tank.
The second method I hope to be prving soon as my new rocker bolts come in! I found that the choke cable, about 6-8" long from my Keihin CV (off a HD 1988 and newer) has the same theads! The cable end that hooks to the enrichner/choke needle measures the same, but the spring and enrichner needles are different. So I just swapped the BST stuff to the CV cable. But again, my bike isn't running, so I haven't proved it works. Once I do and my internet access improves I will post a little write up with the details!

I would love to see some pics of how its coming along and more details of what you did! I've always felt the stock controls were too bulky!

The previous owner of my bike put a Flat slide in, removed the choke cable and put a knob on the side of the carb. The biggest pain in the ass I ever experienced trying to reach that damn thing over top of the cold start button. I went and bought all the stock parts for the stock carb and got them to work on the Flat slide

Think twice before you install just the knob.
