SOURCE: I have a 2000 tw200 yamaha and Im not getting oil pressure up from the base.I took the oil filter out and started the bike and no oil out of there. There is oil in the bike.Don't know if its the oil p

hi gwfu,

tw's are great bike, just have to make sure it is on a tip top shape. you are correct, you may want to check on the pump because if there is no oil going to the filter, then the pump is at fault or the flow of oil from and to the pump may be blocked.

you may also want to check on your seals and gaskets as this may also cause pressure drops.

hope this helps.

best regards,

voodoo

I had a similiar problem with my Vmax. It was the Vboost computer for mine. It is located under the Left side scoop and is a small black plastic box with a round electrical connector. They are very expensive new. I got my replacement on ebay for around 75.00 dollars. I hope this helps.

Air or fuel. Your not getting enough of one or the other. Start with air by removing your air filter (temporarly) and see if that will tell you anything.

SOURCE: Hey, I've got a Max with 5000 kilometers on it.

Sounds more like the previous owner did some modifications to the bike such as a jet kit. The jet size was probably increased in the carbs with no other modifcations. This will cause the bike to run rich. If you do not have an aftermarket exhuust and a k&n air filter already then this may be you problem.

Why is my oil pressure dropping?


first suggestion is to check the oil level in the sump as this indicates that on start up there is sufficient oil but when the oil galleys are full the pump is sucking air and the pressure drops to zero. The level has to be on the top most fill mark.

Well tanny fluid is dirty and it shifts into low gear and jerks alittle when driving


Service the transmission, replace the transmission fluid and filter, and have them check the transmission fluid line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.490" or 0.500" boost valve (easy fix in pan). the boost valve is only an extra $45.00 part and should be replaced every second transmission service. Service is every 60,000 miles. Good luck and this should help address you transmission issues. At worst the EPC valve is sticking due to the dirty fluid and may need to be replaced too which is an easy fix when the transmission is serviced.

I am looking at buying an 03 rm250 tomorrow.Do you have any suggestions on what to look for regarding signs of problems with this specific bike?


Below are generic things to look for if getting a used bike.

Does the engine start easy and idle smoothly? Does it accelerate without hesitation?
Does the clutch engage and disengage smoothly?

Is the clutch lever easy to pull?
Any oil or coolant fluids leaking after a ride?
Do all gages work? Lights, horn and flashers?
Any red lights on the gages lit up? Any computer codes flashing?
Do front and back brakes operate and stop smoothly?
Is the motor oil pretty clean or really dirty? (Sign of how well the owner has cared for the bike).

Is the oil "white-ish"? (water in the oil. If motor is water cooled it's usually bad water pump seals).
Any funny sounds from the gear box? Anywhere else?
Does it shift smoothly up and down the full gear range? Neutral light come on properly?
Sprockets still have rounded tips not pointed? Well lubricated chain?

How much adjustment is left in the chain?
Good tires? How old is the battery? All lights work properly?
Is the upholstery good? Plastics cracked or broken?
Gas tank badly rusted inside? Do the wheels run true or weave?

Do the forks look bent from a side view or front view?

Two month ago my engine light came on and two days later my oil gage came on too i did the oil change and the engine light wen away now i have the same problem with the engine light the first time i did...


A few items come to mind...first, check engine oil for fuel contamination. If you're not sure after a "smell test",
Put a drop on a piece of looseleaf paper. Put a drop of fresh unused oil on another paper. If the old oil forms a wider stain that seems to have a "halo" around it, when compared to the fresh oil, most likely it has fuel in it.When doing these tests use only cold oil. Warm oil will spread faster and give a false reading.
Do a simple "rub test" wipe the dipstick between your thumb and forefinger and rub your fingers together. Repeat with fresh oil. If there is a substantial difference in the "oilyness" between the two, then the oil has broken down. The difference will be extremely obvious if fuel contaminated.
If you determine a fuel problem exists, it likely is from a leaking injector. If the oil is just deteriorated, try using a better quality oil, and definitely nothing with a 5w first number (unless it's a full synthetic). I'd use a 40 as the second number.
