Premix or Autolube ?

Hi all
What is the advantage of running on premix would anybody recomend it for 'Street use' or is it best left for trackdays?

Also how reliable are the 2 stroke pumps on NSR's as ive had 2 MC16's that have seized due to what looks like lack of oil Shocked

Any thought's or advise would be appreciated Wink

MC21SE... 11 years and the pump's still working.

Pre-mix on the street is a pain in the ass! You need to carry a bottle of oil around (OK if you have stock bodywork I suppose) and need to do the silly wiggly dance on the petrol station forecourt, but you do get to measure the exact oil ratio of your choice. You also loose the weight of the components (although you are still carrying around up to a litre of 2T oil in a bottle!) and gain better access to some parts of the motor.

Downside? When you run out of fuel and/or hit reserve at 12,000rpm in top (and that's where it always seems to happen, just so you think you seized it!), you will supply no oil to the crank or the barrels all the time it takes you to get the clutch in and/or turn the fuel tap. With a pump, as long as the drive gear is turning, and there's oil in the tank, it will keep on injecting.

It's all down to personal choice. I'm a lazy bugger and can't be bothered with the hassle myself!

Use the oil pump, and worry not about failure - this isn't a Suzuki you know!
Cool

Oil pump and good oil.

There is always the possibility that your previous problems were not from a lack of oil, but a lack of high-quality oil.

I use Blendzall Ultra 455. It is a Castor-based injector/premix oil made in the US. Smells absolutely incredible, also... Wink

Not keen on Castor oil as i have had problems with it gumming rings before when used in an Autolube bike (although ive got to admit it does smell great though Laughing

)
I normally use Motul fully synthetic oils (mainly as my friend is a Motul dealer and i get it at a good discount Wink

)

Thanks for all the imput ,Looks like the pumps staying then
