IMS Petcock. Should I put on the stock?
Perhaps by open throttle I mean open choke? That sounds more correct

Oh, and vent gas cap tube is fully blow-throughable. Fuel is about 2 gallons.

Therefore full throttle means that the throttle is fully closed. I recommend the use of the phrase "wide open throttle" to indicate that the throttle is open 100% of the way. Similarly saying "1/4 throttle" (for example) means that the throttle is open 3/4 of the way, so a more proper way to say that the throttle is open 25% of the way would be to say "1/4 opening". The only time this makes no difference is with 50% opening, where it obviously doesn't matter whether you say "1/2 throttle" or "1/2 opening".

The IMS petcock is fine. It sounds like the bike is surely starving for fuel.

As long as the bike was running fine prior to your IMS tank installation, there are only a few things to look at:

1. Make sure the fuel line from the tank to the carb is not kinked.
2. There is a tiny filter in the carb inlet (carb side of fuel line) that might be clogged.
3. Make sure the petcock is in "reserve" or "on". I think the directions are different than the stock petcock.
4. There might be vapor lock in the fuel line. (An air bubble if it has a high area).
5. There was a vacuum line going from the stock tank's petcock to the carb. The nipple on the carb where it attached needs to be capped.
6. Put more fuel in the tank?

RM / DR650 Foot peg Interchangeability.

Anyone know if the RM/RMZ foot pegs fit the DR650? If so, what years?

Fast forward to this morning, and I can't get the thing to stay running.

Generally in first gear, as soon as I try to get it to move further, it just dies. There's gas in it, the tube from the petcock to whatever is 4 inches to the right of the petcock seems clamped on fine, no leakage or anything. I've tried putting the vent tube from the gas cap back on, no dice. So why in the hell is my engine dying w/in <2 min of running? I was so proud until this morning...

In short, at the moment I'm an ignorant noob and a dumb brute. HULK ANGRY

Out of curiosity do you have the tank vent tub attached to the vacuum port on the carb?

There is a breather line from the carb on the right side which if pinched by the installation of your new tank won't allow the motor to run for long. I forget exactly which line it is but mine did that once a few years back. Take you tank off and see if it runs. If it does watch where it might be pinching a line when put back on.

I LOVE the diecel popping.

i would pay good money to make a motorcycle sound like a rig.

anytime i can imitate a vehicle that could kill someone in a car and make them think twice about coming into my lane.

thats a +1 in my eye's

I think around 1500 RPM idle is about right to reduce de-cell popping.

Another Tip! EAR PLUGS!

The above is very good advice. Also make sure of your fuel hose routing ... and sometimes in line filters can create flow problems.
fuel does not like to run UP HILL. Gravity is your friend ... and it's why most riders with the IMS tank ROTATE the metal fuel tube either to the 3 or 9 o'clock position.

Also, just for laughs, drain your float bowl.

A Rig?
Fact. Loud pipes will never save you. They simply piss people off and make them hate motorcyclists and lumping us all in with the neanderthal "Bikers" Open Pipe Knuckleheads. I'm never a BIKER ... I'm a motorcyclist. Loud pipes guarantee that anytime that motorist ever gets a chance to vote on anything about bikes ... it will be a BIG NO.

I like a bit of growl ... within reason. The GSXR pipe is about my limit. My old FMF Q2 was too loud for me and brought unwanted Police attention in town. After all ... how am supposed to get away with jumping curbs and riding up stairs of industrial buildings if the cops can hear me two blocks away? With a loud pipe I'd never get away.

"Throttle" can be either a noun or a verb, depending if one is talking about the device or the action.

Are the neanderthals 'Knuckleheads' or are they riding 'Knuckleheads'.

Indeed. A throttle throttles.

Did you thoroughly clean the new tank before installing it? There may have been a bunch of debris in it before. Now it might be blocking the petcock filters or carb inlet filter. Also, blow through the vent tube to check for obstruction.
