    I've been thrashing the he|| out of a rare collector's item? It had 2000 miles on it when I got it, now it's got almost 10,000, and it's scratched all to the devil. I've been all over the West on it, tho, and have plans to ride Baja this summer, and more as time allows.

    I'll just use it 'til it's all used up! At the rate it seems able to take abuse, that may be quite a while! :whip

    I have had mine since new. It has twin low pipes with supertrapp tips. I have change the carb to a Mikuni BST 40, I rewmoved the left pipe and drilled the right to breath better. However, I have added a full supertrapp unit to the right and is upswept like the Rally. She runs really good. 50mpg. I'll try to post some pics when I figure out how.

    AFAIK the fancy tyre carrier bags were pre-production only and were used on the studio bike in the photo above which has the other changes to the production bike already mentioned. Production costs resulted in the fancy bags being dropped from the production bikes.

    This is my MKI Adventure (and a very young looking KTiM), can't remember what year I got it though - 97? - It was one of the first in the UK.

    Just so as not to cause more confusion, the screen was clear but was painted to match the fairing and it was a twin low pipe set up but I converted it to a single low pipe.

    I just finshed working on the bike from my buddies shop, it was poorly taken care of, parts were missing from the engine, the coolent was basicaly mud and rock, the rear brake fluid was crystalized (wow) After new pads, hoses, adjusted the valve clearences, re sealed the water pump, tires, re jetted the carb and lots more TLC the bike is running awsome. I wonder tho- it came with a clear windshield that was original ktm, clear fork boots - maybe its a 96? Anyway i can find out what the year was for sure? The slip on exhaust was a custom full system that came with the bike. I personaly fit the tanks, i had to mod the rear frame to make em fit, no more passanger pegs for this ktm :)

    The bikes running great here in Santa Cruz california, VM717851

    I found this thread very interesting. There is no mention of numbers for the the LC4E model or the SCX models.

    I was trying to establish the total number of 640 LC4 engines that are being operated in the USA. Once we establish the total number, it makes sense to look at long term reliability and then establish a long term maintenance/replacement schedule based on total accumulated mileage.

    The owners manual has some glaring omissions in their suggested list of scheduled maintenance.
    It strikes me that many of the problems with our bikes have to do with lubrication and greasing issues or cooling problems.
    The cylinder head/valve gear and clutch are also problematic.

    Since Iam coming up on 20Kmiles on my bike and am planning another 20K out of country this will be a labor of love.

    Anyone want to take a stab at the total number of engines in the USA?

    Old thread - but it rocks.... I learned allot from it...

    I will add my vin number tomorrow - don't have it on me right now... But I have added myself to the 620 EGS Adv owners this past weekend.. It's going to need some TLC as it spent it's life out side, but it's got less than 6k on it and I got it from a friend who is also the original owner...

    Photos of it are at - http://picasaweb.google.com/jason.picton/KTMProject

    I have already pulled off the sold rusty mirror, and put two left over drz400Sm OEM Mirrors on it, swapped hand guard for one I had lying around, and cleaned up all the tiny surface rust associate with these parts.. I will sand and paint the OEM handguard and will replace the mirrors with some thing else in the future. The 1st thing is to get it inspected and legal - MD requires 2 mirrors - so it's why I did it...

    Today's task will be to swap my leftover SXC dirt front fender :) and this weekend - I will put the dirt wheels from the SXC on it as well.. (SXC is a motard). That way I can clean 'em up whenever - and/or mount new rims to the hub at some future point... Lots more to do... but it's a sweet ride...

    Thanks for this thread....:clap :clap :clap :clap :clap

    Congrats on the new purchase. Now go smack your friend around for leaving that bike outside. It's good to see that it still has the low exhaust. It really doesn't look that bad in the photos.

    There are fewer and fewer of these bikes around. There was just an auction on eBay with one complete bike that had been modified to high exhaust and he had a parts bike that would probably never roll again. That's two fewer bikes in this world.

    Very, very rare beasts indeed. Looking forward to getting the serial number from yours and seeing more pics. :lurk

    LOL ... Yeah - but California was too far away for me.... Plus, I do know the previous/original owner ... If I hadn't have known him.. I probably would have walked away - there are some serious signs of exterior neglect.. I would have worried bout the internal condiion - but it runs strong, and the motor was taken care of - you can see the hoses are in good shape - with little addition to the fuel lines - etc... The only mechanical issue I have is the clutch is softish/mushy feeling... Charlie (the PO) said the it's always been that way... My SXC is NOT like it - so I am hoping it's something simple to fix....

    I like the pipes - but have a few issues with em - they aren't rusty but it looks like the nickle plating has REAALLLY discolored itself in places - ala sitting outside.. I am debating getting em jet hotted silver (would be a flat color - but would match the rest of the bike as most of the metal while NOT rusty has more of a dull finish). They are heavy too, but I like water crossings .. The low pipes are a cause for concern in that area.. A buddy has just gotten into making high mount shorty cans for SM bikes... THinking bout possibly pulling the cans and getting some aftermarket one and having him bend some pipe and make shorty cans for the ends ala the dakar rallye version

    That exhaust is stainless. That discoloration is normal for a bike that has seen water crossings and mud with a hot exhaust. By far the easiest thing is to clean it up with fine steel wool while washing, then leave it alone.

    As for changing to a high exhaust, you will quickly find that the subframe and rear sidecovers won't work. That's all different on the high-pipe models and in order to get the exhaust through the 'normal' routing, you'd have to swap to a newer ('99-up) subframe, airbox, battery tray, etc.

    Since the stock cans have the spark arrestors, I'd just leave it alone. It's a bit heavy but having one of probably 15 left in the country is worth something when people ask you "WTF kind of bike is that?"

    Thanks for the info... I may have misspoke, I know the subframe is different - I was going to have a buddy of mine just make me some longer pipes, bend em up, and put custom cans on the end sort of like this
    [​IMG]
    Of course that means no bags :eek1 .. If they are stainless, I will start with cleaning en up and see how I like it...

    Last question for the day... The supposeded clear windscreen has seen better days - it's solid no crack - but it's opaque... Anyone know of cheaper replacments than $200 for a new one... Anyone paint theres a solid color like the later models???

    DK - love the article on the 620Adv.... I actually found it online when I was deciding to go all the way to Buena Vista, VA to buy it..

    Well, it's my turn to add to the list. I have 2 to add to the list. Yes 2, but one needs some TLC. They are both 97's but one is titled as a 98 and the other as a 2000.

    2000

    serial #- 8575
    engine#- 4593

    This is the parts bike and was never titled until 2000. This supposedly is Jimmy Lewis' old bike. It has the high exhaust and a non-cush hub. I don't have any of the low exhaust parts for it. The motor has a bad crank bearing. It has a number 2 best in desert sticker on it and #065 race number.

    1998

    serial#- 8791
    engine#5078

    This bike has 6300 miles on it and is all original except for the high exhaust. The PO cut a piece of the left sub frame that supports the low exhaust. It was a clean cut and I have the piece. I have all the parts for the low exhaust. The only weird thing is that the original owner cut and capped the midpipe where it splits to the left and right side. So it can be a low exhaust on the right side only, I can find a spare midpipe.

    [​IMG]

    The plan is to rebuild the motor and take the best parts from both bikes and put it on the clean bike. Then I will build the other one back up and sell it. At least that's the plan for now. It is nice to have an Adventure again. I always loved the orange of the 97 and 98's.

    Hi,

    the first year they sold the Adventure 620 was in 1997.
    The bike was launched April (or May?) '97 at the island of Elba/Italy.
    It is still a great bike. If you have one - keep it!

    Are these bikes prone to the engine bearing failure? Also what's the difference between the motor of a 620 and a 640? I thought the 640 was 625cc? Is the 620 motor basically the same as a 640 with a few less ccs? Or is there more substantial differences?

    There's a 1998 620 ADV over in TX that I was giving a serious thought of buying.

    I have a friend in Baton Rouge that has a (I think) 96 that is something sort of weird and rare. It is an LC4 of some sorts with a huge tank. What makes it so strange is that it has all purple bodywork. It is all OE plastic. I only had one chance to see it in person probably 8 years ago, it was really cool, but none of the details except for the big tank & purple stick with me.

    Anyone know what it is?

    That sounds like it might be the 620 SC with a large tank.

    Great work with this post, very interesting to see the history....they really haven't changed at all really :huh

    I am interested to know what the original screens are like to ride with, does the flicked out section at the top of the screen make a big difference with buffeting etc?

    Where can they be purchased? As there is a 04 for sale over here with a very similar looking screen....great bike btw, I would really like to know who built it originally, has twin rear tanks (not shown in pic) & rally style bash plate with tool box & has been painted in a pretty cool livery.

    I'm not certain, I know they were white, mint green & red for a while. And then maybe in the mid 90's they changed to white with Purple (& maybe some yellow) but I think the bodwork was all white with the seat & graphics being purple. I think before they went with their current orange they had a sort of butterscotch looking orange in maybe 96 or so. I think the butterscotch orange still used purple graphics too.

    I remember this bike having purple plastic, all of it. I have not seen an all purple KTM since.
