96 was - as I recall - the only year of the Marzocchi/Ohlins suspension combo and Edelbrock carb, both of which were problem areas. They were very hard to start, and the Marzocchi forks were harsh. If you could get them started and put up with the suspension (or were willing to get suspension revalving done), they were pretty robust and had a lot of power for the day. Eric's in Pasadena and Z Racing in Fullerton should have legacy knowledge on how to make them right.

thanks Mully, you continue to amaze me with your depth of knowledge...

This will be a "learner" bike for my son in Colorado...maybe a "handfull" too. the way it sounds, why is it that my impression that "Ohlins are good" is frequently wrong.....

thanks again.....

I had a '96 RXC. A friend of mine still rides it. My memory is that the Olins shock is wonderful. I'll take it off your hands. In fact, let me know if you change your mind about wanting that bike. I is very fast and kind of tall and kind of heavyish. Also, I remember the Zokes had a reputation for smoothness, rather than harshness. '96 was the first year of the counterbalencer, and the last year before the electric start. Also, the last year of the microfilter. Great suspension, don't fool with it. The fork boots that you have are good, they help keep the dirt out of the seals. Change the fork oil more than you might. The bushings in the Zokes had a tendency to wear if the oil was dirty.

Great bike
The 9L tank is a little tiny. Keep the battery charged. If it still has the Edelbrock carb, try to plan on changing it to anything else. The FCR 39, or the FCR 41 would be the hot sauce.

The Edelbrock carb was used through 98 and is a piece of &#*t. I don't care what anybody says, or how many mods are done to it, it's still junk. Switch out the carb to a BST or even better, an FCR and you will be much happier with the bike. It will be easier to start and run smoother.

dirtbro picked up a 97 RXC last year which is the first year for the e-start. Other than the carb giving him fits, it's been an awesome bike.


LC4's are incredible bikes. Have fun!

96 RXC is one tough bike and plenty fast!
Good pickup.
I'll second the E-Brock Quickslobber comment above.
I FCR'd mine....no comparison, it blows the eBrock away!

this bike will eventually reside at my house, and I am new to bikes, so can anyone fill me in on what a FCR carb is? Is that a manufacturer or a model? Can they be bought used, and if so where?
Thanks for any help that can be offered.

Josh

Hay Jasper, my '96 RXC, recognize any parts?



Throw away the old QuickSilver.

You might want to find a take off BST40 and throttle from somebody upgrading to an FCR39 or 41. They are easy start carbs with the kick only starter. They don't perform like the FCR, but are good all around carbs.

The silencer is a boat anchor. My RXC has an Uptite full exhaust. Nice stuff.

I very much like the big 'Zokes and the Ohlins combination on the '96. It's a much faster bike than my '01 Adventure on the hairy stuff.

mmmm....

My first bike of any kind was a 1995 RXC-620. Big, tall, heavy, FAST --- loved it. Awesome bike. When I first got it nobody could start it when it was hot. Had hot-start button on the carb & everything, but no go. Picked up a gasket kit & rebuilt the carb (DelLorto) for around $20 & it worked perfectly. somehow I blew a head gasket on mine - so opened it up & put a new gasket & rings in, lapped the valves & such - thing ran like a top. Sold it to get the 640 adventure because being in Orange County there's too much pavement to get to the desert & the 640 is a much better bike for long freeway hauls, but the 620 is MUCH better for desert/trail riding. I had a much larger rear sprocket than stock also ... watch the throttle! It likes the front end in the air!

Painted mine black after the top-end rebuild...

Hey Gaspipe-

Your '96 looks better everytime I see it. I have about 6 pic's of it saved up on my hard drive, I think. I prefer the left side because it shows off that nice pipe of yours.

You forgot, this time, to plug those two Up-tite Racing Pipes that I still have. My SXC still is not as fast as my '96 on the top end.

I loved those zokes too. I recommend them to everybody.

You should come on out west this next year.

Jasper

Hi Josh, An FCR is a Keihin carburettor, 39 & 41mm sizes are commonly used on the 600+ KTM's. It is a flat slide pumper style carb which means you get very rapid response. They can be bought from Sudco.com, you may have to hunt down the correct boots, cables & throttle to match.
A far better carb for a learner would be the aforementioned Mikuni BST 40, these are a CV (constant velocity) carb and have less violent throttle response, they are fitted standard to many KTM's & people take them off to put on the go-fast FCR's so ya might be able to find a 2nd hand one. Again, other parts may be required to fit it up.
Enjoy.

Cheers
Clint

Cult of the BST

You might wander over to KTMtalk for FCR stuff. The Cult of the BST executes Heretics, I heard.

Been there. Had the Quicksilver carb worked on at Edelbrock. Bike started without a hitch every time I road it. My buddy had the same exact bike and his had a mind of it's own about starting. Fork seals were easily damaged. Replace them with the green colored seals and they damage less easily. Sold my bike with the one of few made Yoshimura YRD pipes on it. Kinda of wish I still had it now.

2008 purchase, like new 620 rxc

This bike is sitting in my garage with very few miles. I bought it for a couple grand from Corse Superbikes in Saukville. They just wanted it out, I think. When it ran this summer, it seemed a little low on power -- and hard to start.

I've thought about dualsporting it as an upgrade for my really nice and bulletproof KLR 650. It doesn't seem to have more pwer than the KLR, surprisingly -- but that front end MUST be better.

Questions:
1. Where can I get a exhausty for it?
2. Where can I get a carb for it (I think it has the Edelbrock - great carb for a small-block Chevy)?

Thanks,

Andrew
