My r6 running too fast when started

On cold days, the yamaha fuel injected bikes rev higher to warm up the engine quickly. It is still ok to ride the bike on a cold engine, but it will perform much better when the engine is warmed up.

I bought my Shine 1 month before. From the time I bought, I am facing a problem with the bike. Every day I have to use the choke for 5 minutes for the bike to start and run. If I remove the choking just...

1. Sounds like maybe fuel line from gas tank is clogging. Clean gas tank. To check, remove some gas from tank and run it through a paint screen.
2. Replace gas filter regardless.
3. Could also just be water in gas tank. Drain some gas from lowest point of tank (usually the reserve), into glass jar. Water should settle to bottom.

I have a 2007 Volvo S40 2.4i. When accelerating, it feels and sounds as if the car is not getting enough fuel, but I am not sure if this is the cae. I replaced the fuel filter and it was better for 2 days...

It did happen to me too.Is true that i had another mark but anyway , you can look on it. Gas hose can be throttled and cannot let the fuel to accelerate the engine how it should.Good luck.

2001 yamaha ttr 250, starts, idles ok, bogs at acceleration

Has the bike been stored for any long length of time?
old fuel in the carburetor will turn to a varnish like residue blocking the jets,or possibly water in the carburetor.

Hesitates and backfires through the exaust when accelerating

Sounds as if your timing is not quite right. You need a manual, but The best I can offer is a 98: , it may help, but if you only have 1100 miles on it, I would be taking it to a qualified mechanic to be fixed. Up to you.

Yamaha TW 200 starts but won't run.

If the bike has sat for a long period of time without being run - the gas that is sitting in the carb(s) will shellac.. Then the carb(s) would need to be cleaned and "rebuilt"..

Bike starts ok runs ok when first started,when temp gets to about 80 degrees,it stalls,runs jerky,wont idle ,lack of power,could it be the T.P.S.

i think the engine oil is the problem.
because i think at above 80 degrees it is loosing its viscosity due to which the piston is slipping inside the cylinder.
change its engine oil .

Jerky accelerating, late response to gas being pressed

Well for one, make sure you speed up slowly, dont HIT the accelerator. It may also be problems with your fuel filter. After you are stoped fuel stops running through the fuel pump/filter and then when you start going its starts to run through again and it cant keep up so it gets bubbles in it and doesnt move throught the filter easily hence the jerky accelerating. Good Luck
