ma2 motorcycle oil

[rkl789]

I have a oil change coming up soon and want to try it out using motorcycle oil this time.

Any recommendation for any brand?

I use this one which was recommended by Martin and had no problems at all

The latest thinking on oils for the AP transmission is JAPO MA2, this translates to Japanese specification oil MA2, which is a motorcycle oil, however it must NOT be confused with MA or MA1 which are not the same and are useless for wet clutches which the MA2 excels. make sure to get 10W40 grade so the pistons and valves work as they should.

How does this MA2 oil go with flat tappets?

Very well. Here is an analysis of one. Antiwear additives are a little below a CJ-4 diesel formulation, and way above a SN/GF-5 ILSAC car level. About 3 to 4 times what was used back in the day of flat tappets. Once the premium products came on the market in the late 60's, they were up to about 1/2 what MA2 has, but of course with poorer base oils.

Here is a sample oil analysis
