what would be the best oil for a high mileage f2? and ive been looking for a wiring diagram for the rear turn signals, and can not find anything. The wiring is really butchered on my f2...stupid kids and their wiring..


thanks,
tom

 

If you download the free manual online it will have the wiring diagram, mine does, just Google cbr600f2 workshop manual or similar. As for oil stick to 10w-40 of your choice and try to change it every 5k miles.

 

ditto, buy yourself a haynes manual or equivalent as well they are very useful.

I use castrol 10-40 and change before 5k miles but do the filters as well and you will be fine.

 

thanks, i was thinking 10w40, and ill prolly go with the actual manual just to have. wifi doesnt get to my garage! lol

 

How many quarts would I use for the motor?

 

3.9 apparently but if you havent stripped the engine you never get it all out.
the manaul tells you to drain when hot via the sump plug then remove the filter.

add oil keeping an eye on the dip stick, i usually put about 3 quarts in and let it settle. when there is enough above minimum run the bike for 5-10 mins, let the warm oil drain back to the sump (5 mins) and check the level again.

oil level is always checked on the center stand and with the dipstick just sat on the threads not screwed in.

 

o wow, i never knew about that, i always checked my bikes with the dipstick screwed in...anyone else check it screwed or just on the threads?? thanks

 

and also, since i am the third owner. would it be a good idea to use synthetic oil? the bike is jetted to stage 3 with a power commander and an exhaust (36k miles)

 

its all synthetic just some is semi synthetic and some is fully.

the jetting and exhaust dont impact your oil choice.

i personally use semi synthetic because I change it so often that any long life properties of fully synthetic would be lost. i also believe it runs better on semi but i may have just convinced myself of that ;-0.

there are a lot of old posts / debates on here and other forums so search and see if you can find an answer your happy with. i couldnt find a conclusion so got bored and went riding ;-)

 

My high mileage f2 doesn`t like full synth 10-40, it comes straight through, a liter of loss in 1000km as smoke in the sky so I swapped to Castrol Act>evo 20w-50 and haven`t had a problem since, the only thing is if you ride near freezing point let the engine warm up properly as that stuff is like syrup when cold, you feel a clear change in the operation of the gearbox once the oil warms up properly.



This time I bought a can of this as the Castrol is extremely hard to find here, the last time I had to go to three shops to get the required four bottles, plus this stuff is considerably cheaper so if quite a few of the guys use Shell Rotella oil which is meant for commercial lorry trucks I`d reckon this should do the trick as well, the only vessel the Rotella is available here is a 200l barrel...

And a big +1 on the Haynes manual, don`t have one for the CBR as I`ve managed without but did get it for the Daytona and have needed it many times.
