The hump also means counter balanced engines won't fit into frames from non-balanced bikes (but non-balanced engines fit into the balanced frame). I found that out the hard way.

I had a '96 RXC 620. I replaced the Edelbrock carb with a 39mm Keihin FCR. It ran so much better and was a direct bolt up. A 41mm would have been the cats ass as I'm sure the motor would have liked the greater flow. It would be possible to ride it for longer distances, but the motor will vibrate a lot. What gearing are you running? Make sure your valves are properly adjusted, change the oil regularly, and have fun. Being kick only is no big deal once you get the starting ritual figured out. Since it's a tall bike and I'm only 5'9", it was easier for me to kick it standing off the bike, with it on the center stand, from the left side. Feel free to contact me with any questions.

The 39 is better for more power lower rpm, 41 top end,, most seem to go 39 if they ride nasty off road.. the dukes and more sumo guys go 41's..

That thing is so clean you could eat off it, RW!
I like that action pic!

What kind of Rad guards do you have on there?

Thumb 97 Lc4 620

Picked up a basket case a couple weeks ago . Stuck a Mikuni HSR 42 on it. A few mods to the throttle and bingo. Hard to find info on the older KTMs. Dealer told me they didn't even sell any in the US in 98. Seems to be a change over year. Not too much available in aftermarket as far as I can tell. Any help in that area would be great.

Hey Harley Dude, welcome aboard!!!!!

Check the LC4 Thread Index for all you need to know for living with your LC4.

Not pinned in that thread is the need to swap the oil seal on the end of the crank. It presses into the clutch cover and is an easy and cheap swap.

Radiator guards

+1 on the radiator guard question. Also what exhaust is that? Nice looking bike, RW!

Here is mine.
Its a 96 Super Comp model.
I really enjoy it, it has a dellorto carb, and it works like a dream unless i drop it
I have a small problem with it, few days ago i noticed that the front sprocket is missing like 4 or 5 tooths - they have snapped. Will replace the sprocket asap. In winter period, i use trelleborg winter spikes and they are awesome
few pictures :

color?

cool ride I have a 97 RXCe with the same color combo. Just picked it up as a basket.Stuck lights on and a mikuni hsr42 Have not gotten it through Emissions inspection yet so I have not ridden in the dirt. Just a few blasts around the block. What pipes are available and what other KTM models interchange wheels and brakes?

The dealer is giving you bad information. There were 98 models on the floor here in WA. I believe the gray and white one pictured above is a 98.
