    My 625 SXC had the Mikuni BST 40 carb on it. Bike ran fine. Since I am in the bike parting out business, I got a FCR 41mm carb from a 2005 525SMC and replaced the Mikuni. I know the Euro spec bikes have this carb. I did nothing but adjust the throttle on it. What a huge difference. First off the bike starts up really easy now, be for it was a pain. The bike response so much better too. Getting the airbox on the carb was not easy but I got it on and it ain't comming loose. I would recommend the Keihin FCR over the Mikuni. A little pricy, but a much better deal. I got my 625SXC rather cheap. The starter clutch (free-wheel foward) was chewed up. and the bike was hard on batteries. I hear starting on this modal was an issue. Now with this carb, it starts as easy as my Honda 230L did and I almost never have to choke. The FCR carb also has no throttle sensor like the Mikuni, the only thing I sensed with the BST carb was that it didn't work well, I have come to the conclusion the Mikuni BST carb is garbage. I never even checked the jets, no clue what they even are (probably the 525SMR jetting). I live more or less at sea level. Just rode up in the Sequoias up to around 8,000 feet no issues at all.

    remember there are very few differences between the LC4 models, mostly cosmetic. most of the engine/frame/suspension is all the same.

    Hey guys, this is some great stuff, I've read through this thread a few times, and I'm not sure what I'm going to do here.

    I'm in the market for my first bike(not my first time riding), and it's going to be for ADV for sure. I have come across two bikes on craigslist, a 2000 KTM 625 LC4 for $3000, and a '97 KTM 620 RXC for $2800.:eek1 I don't know anything about these bikes, but I've been told maintenance on them is going to be expensive, and parts are difficult to find.

    Is that a myth? I've been thinking more around the lines of a ol' DR650 because maintenance would be simple and there are parts everywhere.

    You guys sound like you would never sell your KTM's... This has me thinking and listening to what you pro's have to say... :ear

    If condition is similar go for the 2000 625.

    Not sure on parts prices & availability where you are, here there's not much in it between a DR650 & an LC4. Have a look at a few common parts at some online retailers to get an idea.

    Maintenance wise the differences aren't large either, a service on the LC4 might take another 20 minutes over the DR due to the slightly fiddly valve check & the extra oil filter. Oil changes are more frequent due to the smaller oil capacity of the 625. You will have to service the water pump every 20K miles or so.

    On an LC4 of that era it is a good idea to replace the LH mainshaft bearing with an upgraded one, on a DR650 of the same age you'll probably need to upgrade the cylinder base gasket... again, line ball.

    DR650's are great value, & a much smoother engine for touring, but if you plan on doing more offroad, maybe some little jumps now & then :evil the LC4 is great.

    Cheers
    Clint

    i would say it all depends on what your going to do with it? if this is going to be a off road only bike then it kicks ass. there is no hill you cant get up in 2ed or 3ed gear, it will putt along and pull like a tractor. one down side is its quite the "paint shaker" , its fun on the street but remember that the tank is alittle over a gallon so the rages kind of sucks. but its a awesome bike and you wont be let down if you get one. i must say i do love mine alot

    Awesome! I have been going back and forth between a DR650 and the KTM LC4 series for a while, they both sound to be a reliable and fun bike, so I am working with the guy who has the 625 for sale to check it out and test ride it.

    I really need to test ride both bikes before I decide. One thing is for sure, I can't wait to hit the road/dirt!!! :p3rry

    Thanks Guys:wave

    Just didnt know if folks were still using this thread. I just got my bike a month ago. I love my 625 sxc. i got rid of a heavily modded drz 400 for it. I can hit the trails just as hard and i shift into 5th around 55-60 on the street. I went down the interstate last Sat for about 15 miles and it was great. drove around 75-85 didnt notice vibes. the bike was solid as a rock and no wobbles with MT21 tires on it to the exit and then hit the trails and got both wheels off the ground numerous times. the manual says oil changes about 1500 miles but i ride hard so i do not mind doing them every 500.

    i put a very small oil cooler on and a CRT behind the radiator. Done some odds and ends to get it the way i like it...and hit the trails...P.S. i got the 18L big tank on it and i got 170 miles before hitting the reserve. I do not even noticde the wieght. ofcourse i never tried the smaller tank. i have both because they came with the bike- but i have no reason to go back to stock...

    What brand oil cooler did you put on. I would be interested in the details and photos.

    first attempt. i decided to turn it around and mount it so the lines go under the motor but i wanted to show you the pain in the butt part. the cooler lines are big and the banjo bolts are small. i had to get a brass fitting from lowes that has a 3/16 barb on one side and is threaded like a bolt on the other. All i did was jam the threaded part into a 2inch piece of hose that came with the cooler and clamped it down. then i clamped the small hose to it and ran them to the filter and to the case. the blue hose is my CRT (coolant recovery tank) hose. i mounted the ktm CRT behind the radiator

    another view- i had to order 3/16 steel braided hose from ebay. it has not gotten here yet. all i did was took the oil change bleed hose off. The hose that goes from the filter to the left case. i took both banjo bolts apart- turns out the banjo bolt is held on by a 3/16 barb. Then i got some 3/16 hose and some hose clamp and clamped it all together.
