Re: DRZ400s question
My son's DRZ400s has been sitting in my garage. It has not been run since November of last year. I want to get it running again, but don't know if I should just try to start it; or if I should empty the gas tank, refill it and then try to start it; or if I should have the carburetor cleaned gas tank emptied and then restarted.
I had issues with carb gunking up really fast on a TTR125; so I would appreciate any advice.
Drain the oil and refill mostly as a way to confirm no gas leaked into the case as is common with stored DRZ's And at less then 2 gt, cheap insurance, good maintenance practice all around. (In a perfect world, you would put the bike in to storage with a fresh oil change and topped off gas tank no air, using Race gas).
Remember, do not reuse the OEM case drain plug crush washer, if you use a new OEM crush washer, install it correctly
and go easy on tightening.
Other wise you get this early B day present
And try and start with a jump battery connected,,,,,,,,It wont start, or it will and wont idle
But no harm in trying strange things can go right.
When it wont start or wont idle, drain old gas, and clean carb.... Sonic tank would be best, but baring that, go on line and order a can of PM3 Motorcraft - Carburetor Tune-up Cleaner. Its banned in Uk and EU countries and CA///So you know its good stuff..... But really it does work best I have found.. NO RUBBER PARTS.
Disassemble the carb completely. Plan on replacing the O ring at the fuel valve seat it will be bad. Its an Odd size 7.75 I.D. x 1.53mm , only available from a few sources I know of....the needle and seat will likely be ok and not need replacement, but the full set is all the OEM has. I'll post two other sources for just the o ring later.
EDIT Ok its later ...LOL

LOL, well it was $3 till we bought him out, 1000 packets in a week..and now that he restocked, the price went up to $6.43 ....And he is out again, sorry, just bought the last pack a few min ago. I was giving them out, but as his pricing keeps going up, cant do that any more.
Check each passage with a shot of brake clean .. Personally Id toss the pilot and starter jets and install new. The main is easily cleaned. If you have the correct jet cleaner tool, the others can be cleaned. I do, and still toss them often as its not worth my time and once clogged, they always seem to clog again sooner next time.
Once gas, carb and oil is addressed, give her a start, check for gas, coolant and oil leaks, if you have a volt meter, check charging voltage, 13.2 or better and your ok, with the "free Power Mod, you should be at 14.2~14.8 wihch is better.
