All three holes every 5K.

 

What the manual recommends on my model. 5k,10k, and 20K... ish. If one surpasses it on a road trip or if I'm busy I don't worry about it. I change it when I get around to it. And I ride some in the winter so I don't worry about the "pre-winter storage" change some people do.

It's just not as big a deal to me.

 

the manual:

engine - 5k
primary - 10k
transmission - 20k

what I do:
engine and primary every 5k
tranny - 20k

 

engine & primary beteeen 4 and 5 k
trans evrry other engine oil change

any 20e 50 synethic, 10w 60 syn in summer
straight 40 wt oil in primary

any synethic 75 140 in trans.

all non motorcycle oils

 

Seems a bit odd to do motor at 2500 and primary at 3000. I take it you enjoy doing it twice? If not, I'd get risky and do them both at 2500 or 3000. That's just me tho.....

 

I'm in the "follow the manual" group as well.
And on my cars/trucks that have maintaince reminders, I do it when it tells me to.

And I have never had a failure from oil/lubrication issues either.

 

3K engine
6K primary
10K tranny

This is what works for me. Easy to keep track of.

 

Engine: 5K or one year
Primary: 5K or one year
Tranny: 20K No time Interval.


Valvoline, in engine
ATF, in primary
Redline Shockproof Heavy, in Tranny

 

every 5000 all 3

 

Ya I like to do only one of them at a time. I start the bike for each different. The motor start for a second two times with a short brake in between which pulls a extra 1/2 guart from sump, got tired of it being dark right after a change. The primary I pull in the clutch and rev a couple times. I could do primary first and do at same time. But really like to mess with my bike alot and this is just where I feel they start to get dirty. Running amsoil in the primary so it goes a bit longer. We all know they will go longer but I have but 40,000 miles on this bike that has 110,000 on stock clutch & it hasn't needed ajusted the whole time I've had it. Tried many things in motor and primary and have found what I like. M1 15-50 motor & amsoil primary with 25% amsoil ATF. It's just a cool running 88 with two cooling mods & clean oil.
