Switched this past Saturday to the Spectro on the trans and Mobile 1 in the engine...Formula + in the primary.

Have to say didn't notice any change in the transmission when changing from the Formula + to the Spectro for the 6-Speed. Still, going to stick with the Spectro.

I have read this thread until I am blue in the face. I am in KS and can not get the Spectro oil right away. My bike will be done soon and I am going to follow your engine break in advice with the 30-60 MPH 10 times in 3rd gear. I can not remember who said it you or the web site you linked to, but said to change your oil in all 3 holes immediatly following. Since I can not get the Spectro what is your second choice for the tranny. Also any other advice on the engine break in other that what is stated? Thanks.

The engine oil and filter is the important one. the others can wait for a few hundred miles. I like to change them after some riding to remove any contaminants in the oil from factory manufacturing processes.

Redline shock proof in the trans or even Mobil 1 gear lube either weight based on the area/temps where you live.

I went today and bought another quart of Spectro 6-speed trans oil and the price went up to $25! That up $6 from a month ago.

Is it getting more expensive? How much are you guys paying for your Spectro trans oil?

My source for Spectro is still holding at $19. The engine oil is @ $8, and the primary is $11 or $12. I didn't go for the primary this time, (last time they didn't carry it & I had already picked up the Formula +). Hope mine doesn't increase any more.

The Formula+ will do just fine in the primary Joy.

That's what I figured, and it was a few bucks cheaper.

I have an 04 with a 5 speed what is the best lube for the transmisson. I just switched to Mobil V twin in all three locations. Next fluid change I'm going to put the Spectro HD in the primary and then ? in the tranny. Does the Spectro 6 speed work good in my 5 speed?

Thanks,

The spectro 6 speed CAN be used in a 5 speed but they also make one for the 5 speed too.
Also use a GEAR oil and not the V Twin in the trans. Best off not using a NON synthetic in the primary , try the Formula+ from the dealer in the primary.
