FCR 41 Carb off a KTM 450 SX-F. Great upgrade for DRZ400, KLX400, DR650, XR650 with a stock carb. Complete carb and comes with throttle cables and throttle tube assembly. This has the integrated hot start so no need for an additional cable or purchaser of hot start lever perch (if needed). Also has adjustable A/F screw and "oring" mod with grip wire already installed.
Buy the correct boots or adapters for your applications, jet according, and enjoy the increased power and throttle response. Was originally purchased for my DRZ400 440 Big bore project but ended up not purchasing the 440 kit and kept a FCR39 on the bike instead. Can pretty much fit any 400+ CC bike with proper adapters/boots.
Will ship to lower 48. Feel free to ask any questions if you have any. PM or Email is quickest
Thanks for looking
I am really needing some good advice here from anybody who has ever owned or rebuilt classic Yamaha 2 strokes (1989 - 1994). I live in South Africa, and bought a little farm thumper while on holiday this past weekend. It was advertised as a DT175 which is a bike that is easy to get parts for down here. It has been cosmetically customized and looks pretty darn cool... and lets face it, all the old classic Yamaha 2T engines look the same at a glance! So I genuinely thought it was a naked DT. The bike had no papers, and was used purely for the farmer to putt around on his farm.
The only things needing attention was the stator cover which had snapped in half - this was visibly noticeable, and a little leak from a badly resealed gasket (both generally easy and cheap to fix here). The bike was still running and idling fine, started first kick, and I had a little ride around the farm before loading the bike up onto my pickup and heading off, thinking I could fix this thing up nicely in no time for next to nothing, and have what we call down in SA "a nuwe speelgoed" (A new plaything) for the weekends when I am not riding my beloved and reliable DRZ400SM.
SO, I get home and decide to contact our local Yamaha branch, out of interest, to find out the history of the bike before I start fiddling (Don't ask me why I did not do this all before I bought the bike - It was a spur of the moment purchase, and was sold to me for dirt cheap!). I send off the VIN and engine number. Comes back, and this little freakin' turd turns out to be a 1989 TDR180!! WHAT. But now I am stuck as we do not really have TDR's down here - and I have never even seen one myself.
Long story short - What alternative could I use as a stator cover? Do any other old Yamaha 2T model stator covers fit the TDR or share similar engine parts? Ordering from Ebay is so expensive thanks to my country being in junk status due to a junk president. So the shipping costs more than the actual item does, and our customs is a joke too. Yamaha has also advised me that this stator cover has been discontinued.
I have put up local ads looking for parts, contacted FB 2T groups, and local shops. Nothing for TDR's has come back yet.
Any advice or sharing of experience is welcome!

Hitting your landing target is critical in motocross. It is also better for your health! Not only hitting your landing, but getting there quickly is also important. The two most common techniques regarding jumping are absorbing the take off to stay low and launching the take off to clear an obstacle, to make it to the landing.

One of the major shortfalls of the DRZ400 is the front/rear suspension in stock form. Early non adjustable forks were too spongy soft and later adjustable forks were stiff and tracked poorly. The rebound only adjustable rear shock was a bit better than the front end but still left a lot to be desired. Compared to my Husqvarna 610 it felt downright anemic and dangerous. While you can sink a bunch of money into revalving, respring, racetech, ect. and end up with a nice ride, I was more interested in what I might get with a bolt on swap.
If you read through the forums there is ample info about which forks can swap onto the DRZ with the RM forks being the preferred. However, there are lots of variations in offset which complicate which year to buy, it's a little vague what exactly is direct compatible, and there are a ton of opinions on how it will ride better/worse etc, but very few reports back from people who have made the swap. That's why I'm writing this up.
I chose to take a less expensive route which I feel looks better and performs to a level Im used to with my 2 stroke MX bikes. I direct swapped the triples and forks from an 05 RM250, reusing my stock wheel, rotor, caliper, and headlight with a DRZ400SM headlight mount, all sourced online for less than $200. All of this was direct bolt on with no modification. This change alone was night and day better in every way. It held a line with much more confidence and less chatter, it handles soft sand more like it's riding on it and less like it occasionally plows, it rides much smoother at higher speeds, and it's less twitchy as opposed to more. It felt much more nimble and lighter even though any weight loss was minimal. With just the front end swapped It immediately felt on par with my Husqvarna. In fact, it feels so much like my 2 stroke MX bike that I was genuinely suprised. This was all with the stock rear shock which now felt too soft and the new limiting factor.
For the rear I direct swapped an 06 RM125 rear shock and reused my stock drz spring to help manage my weight. Realistically I should be running a slightly stiffer spring but with the addition of adjustable high speed/low speed compression that comes on the rm125 shock, the rear end management feels again substantially improved. The speed, confidence, and aggression at which I can take obstacles feels like a completely different bike.
It does sit higher. By my measurements it has a bit more travel now. To my surprise, it feels better on the road up to 80mph and tracks very well with maybe a tad more brake dive than stock.
All this being said, I'm not saying you should make the swap. I'm not saying it handles better than a boat load of money thrown at the stock forks. I'm not saying that my style of Southern California Ocotillo Wells desert riding is directly comparable to your style of riding. What I am saying is there is a lot of erroneous information about how this swap might perform and if it's worth it over stock. I feel based on cost and performance that it hands down is absolutely worth it!
Feel free to post up if you want to know more. I would have appreciated some real world experience before I nervously made the leap.
