Clark Desert Tank

I bought a barely used 2007 CRF450X from a friend who knows very little about motorcycles. He bought the bike new from the dealership and had them install a Clark Tank on the bike. It is obviously a higher capacity tank than the stock tank, but I don't know for sure how big it is. How can I tell? Also, is the reserve built into the tank, and how much does that hold?

Probably in the 3.2-3.6 gallon range and Clarks are well made IME. The only thing that bugs me is the nut cracker volcano which is why I went with IMS. I have a nutcracker Acerbis on my YZ which I've learned to really despise. Getting narded and roosted is not fun for me.

..always rape and pillage prior to burning...


iz it the other way 'round...

I looks like a 3.4 gallon as compared to that site, but anyone have an idea about the reserve capacity?

Reserve capacity is the same as the stock reserve capacity. The extra fuel capacity is all higher than where the reserve side of the fuel petcock comes into play.

This is true... because the petcock, is same same.

The reserve is based on the short tube that extends into the tank.

However, if the lower portion of aftermarket tanks... take on a different shape than stock, whether larger or smaller... the tanks reserve would then change capacity.

... I think we're safe to say, most 450X tanks reserve are similar.

Unless we speak of the 4.0 IMS or 6.0 Acerbis... even though the belly of the tanks is near same... there's plenty of "reserve" down in the wings of the tank... funneled to the carb via multiple petcocks.

BTW, those darn oversized Clarks... I call'em FrankenTank, as they seem to have a ball crusher that looks like Frankensteins forehead. I had one on my '06 Husky... and man, thank goodness I never had an issue!

I have a ball crusher on my x and when standing my package is to far away(im 6ft 4) to worry. I have cowboyed the x rode it all the way to the ground. I think my balls headed north and were hiding in my helmet before impact so that part of the tank never tested.

      Anyone having or had problems with the starter not turning over easily on the 450X???
      I have read about this problem on CRF's ONLY and not seen anyone come up with a fix.
      Problem being is that you think there is a problem with the battery, when infact the battery is OK. When you have a good fully charged battery in the bike and press the e-start, it turns over very slowly.
      I have checked the electrical circuit and it seems OK. I am wondering if it might be the starter itself - any suggestions?????

      I've studied the Jetting sticky's but still have a number of questions:
      I bought my '06 a couple of years ago and had a smog block-off kit installed and the pilot jet was upsized to a 48 and the air box opened up top only. The bike has appeared to run a little lean at times and got hot on a couple of occasions in elevation and on one other occasion. I'm looking at upping the main jet to either a 165 or 170 to help with the possible lean condition. The bike currently has a 142 main jet in it which I believe is the stock size. It looks like the most widely used Needle Jets are the JD Red, but it doesn't look like they are sold separately, is this correct?
      I was going to also get a 45 pilot to have options for further tuning. My assumption is that every bike is a little different and that where you ride is going to have a lot to do with jetting. We ride mostly, mojave desert, baja, and southern Utah with elevations from sea level to 9,000 feet but the higher elevations are generally for a short period as we generally continue through the peaks and head back down.
      I'm looking to convert from a stock exhaust to possibly an FMF Q4. I want something a little throatier but not overly loud and will provide a balanced flow of intake/exhaust.
      So can I get the JD Red Needle Jet by itself or can I get by using the stock and move the clip and be just as happy. I'm just looking to enhance overall performance of the engine and maintain reliability.
