whats the easiest way to install and adjust it? or do i have to take the top of the motor off to check how tight the chains get? or can i just remove the old tensioner put the new in and just tighten it some and go from there? trying to go the easiest route here

When I used to ride a cbr 600 f2 I just installed the new tensioner and then tightened it only until it stopped making the horible chain slapping noise. I wouldn't tighten it anymore than that. I would guess it will be the same on your f4i... they can't be that much different.

Kaotic

yeah, what i was going to do. was just guna tighten it up until it gave resistance or somthing then back it off a few turns.. not sure if there is a special trick to it or not

That's exactly what we did on my F4i, turn til resistance and back off 2 turns, and it worked fine.

Had to drop my engine though.

Kaotic

guna try to get it in without droping it cuz thats a ***** lol

Dano

i did it without dropping the engine, it was a pain in the *** to turn the bolts though

nags

I did it with just the tank and throttle bodies off.. was tricky but not impossible

Dano

i didn't take anything off, just lifted the tank and moved it aside

Im gonna do it on my spare motor while its out of the bike, even tho the stock cct is still fine

Here's what an APE tech told me-

Get it adjusted to the point where it doesn't make the chain noise and no further!-then with the bike idling carefully tighten it while watching the tach. As soon as your idle drops slightly shut off the bike, back off the adjuster 2-3 turns and tighten the jamnut.

I installed mine by taking off the fairing and the tank, but like Dano said there's not much room. Just be patient it'll take awhile to get everything tightened up correctly.
