Hi all

I have a Saito 125 which I am still currently running in. So far I have followed the instruction manual and have run three tanks through it. When I turn the prop by hand, I can hear a distinct 'bearing' type sound. There is no play at all and no grinding feel,it all feels very smooth and runs fine. Just wondering if this sound is normal or if I should worry?

Thanks
Wes

Hi,
I had the same problem... itws apear as common Saito problem which caused by lack of cam gear lubrication ( the excess oil inlet located on the backplate and as result minimal amount of oil get into the cam gear area ) ,
you should remove the valve cover and then drip oil into the valve tubes

Thanks for the reply. I did do this before even starting for the first time but maybe it can do with some more!

Dought it,if you can hear that sound you say you can i've heard it to.Most people call it 'fussin over your new pride and joy' throttle it up after three tanks and give it a bit of a caning(sorry..tune up)

Wes, make sure you're not mistaking the air rushing in and out of the vent for a bearing noise, it can be anything from a low moan to a high pitched whistle. The cam gets lubed just fine Saitos.

Thanks for the replies guys, it's definately abearing on bearing sound. Quite distinct. Will see how it behaves once I have the running in procedure finished.

On any new Saito, I like to pull the valve covers and run a few drops of oil down the push rod tubes. This should make sure there is a little lube in the cam and rocker arm area prior to that first run.

From taking a lot of new Saito engines apart, some have Moly grease on the rod journals, rocker arm pivots, and the cam.

Others are dry as a bone.

Depends on who put them together at the factory.
