fcr carb #'s

I just bought a fcr carb for my 05 DRZ-SM. It was used, and have no idea what size it is or if it will work. so I call apon the gods for your wisdom. :applause:

5TA1 00QH21 are the num. it has a TPS but no hot start. he told me it came off a 03 YZ 450. I need the truth! please help for I am in the need for more HP. thank you.

i believe they are a 39mmfcrmx carb on a yzf450 and if thats correct then it should work.i have a 39mmfcrmx on my drzsm and had only a couple of probs to overcome.but you say there is no hot start and i think the yzf has a hot start.i could be wrong though but my 99yzf400 had one.i think the newer versions had a handlebar mounted hot start button.

hope it works out for you because you will be happy with the results

did some investagative work and was wondering this carb does have a hot start that was on the clutch lever. I thought it was a decompession lever but found out it is a hot start. still don't know if it is a 39mm, and is there a way to bypass the hot start valve because I don't think I need it on the DRZ. thanks for the help.

if you go to yamahas web site and click on the yzf450 specs it says 39mm fcrmx.i'm sure you can get a plug for it or something.i left mine on but mine is the pull out type like the choke.

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!

      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks
