Shifting into 2nd from a stop is no problem. But if you start riding in 1st gear and try shifting into 2nd you have to basically rip it in there as it clunks/grinds. So lately I've just been starting in 2nd gear. Any ideas?

 

Is the clutch adjusted to properly dis-engage? You shouldn't have more than 1/4 to
3/8" movement of the lever before you feel it pulling the clutch.

Another possiblity is the shift-lever adjusted too high? It should be riding your toe.
You should apply a light, firm pressure against it, THEN pull the clutch in and give
that last strong nudge into the next gear.

These are a couple of things to check first, ergonomics/technique is an often over-looked
consideration.

After that, I'm thinking your tranny/clutch may need some attention. Either one will
give you the symptoms you're describing.

Hope this helps you, Ern

 

I had the same problem up till recently (my 1st to 2nd gear change inadvertently falling into neutral if I didn't upshift hard enough with my toe), but my oil was already due for a change after 12,000km (7500 miles).

Having just changed into a thicker oil (yesterday, actually), the difference is amazing. I do use an Australian oil that is 10W/50 (Penrite Gas, suitable for motorcycles too) - that is a fair bit thicker than the usual 15W/40 that I believe the F4i is specified to use (or is it 10W/40?). I'm sure you have the equivalent type of oil in the States.

Anyway, even when 2mins into a run now without the oil being fully warmed up, the gearchanges are very quiet and precise, so perhaps if you haven't changed your oil, you may want to look there first ...

 

I actually changed the oil right after posting this yesterday but haven't had a chance to ride it around yet. Will report back.
