For all who have gone to a 17 tooth front please advise.

15 FJ-09 over 7k miles on OEM chain and sprockets.  Thought I'd try a 17 front and see what I thought.

I don't have enough swingarm slot room up front. never had this problem on any bike.  Rear axle ALL the way forward and not enough slack in chain to put on 17 tooth front. If I could there would be ZERO chain slack.

Guess I should be happy my chain has zero wear yet.

Pic is all OEM chain and sprockets with my normal 1.5 in. chain slack.

Of course pic is upside down.  GRRRRR!!

I didn’t know that one extra tooth would make it so tight. I went up 2 teeth in the back and definitely had to buy a longer chain.

That' strange. On my 2016 I swapped a  17-tooth in with no problems using the stock 110-link chain.

I did need to remove the rear tire to get the sprocket installed, but once the chain was seated on both sprockets there was plenty of adjustment on the swing arm.

I like the RPM reduction the larger sprocket provides.  Now pulling 5K RPM at 80 MPH.

In opinion, if those pics are your current settings, somethings not right. To me, if the sprockets are orginal, the chain is too short.

Those measurments marks should be further back closer to the mark on the swing arm. Count your links.

I guess To cover all bases I should count my links.

It was used with only 1K miles on it. Can't see how the chain or sprockets were messed with. 

There is no master link (endless OEM chain)that much I know.

There has to be a master link, otherwise there would be no way to install it on the bike.

Hmmmm...After dinner I'll go get intimate with my chain and report back.

Well, no surprises. 110 link endless chain. Checked both sides for a master link, nothing.

Does beg the question how do they do that through a reinforced swingarm???

Does Yamaha send swingarms to DID chains for installation?

Does Yamaha have a heavy duty DID stamp tool?

How many teeth on rear sprocket?  Maybe that is not stock?  Swing arm stock?

All I can tell you is with 110 links my 17 fit my 2016 FJ no problem.  Your chain seems suspect to me. Gotta have a master link someplace!

Wish I could help more...

Solution might be to order new (110 link) DID chain along w sprockets.

Nope, all stock. I must have got a good chain. 7500 miles and no stretch.

I do lube it with Dupont at every fill.

I'll just keep riding it the way it is, not going to waste a good chain.

I still wonder how an endless chain goes through a swing arm.  I scrutinized every pin on it, all the same.

Hmmmm, my tracer gt runs a 118 link chain when using stock sprockets…..16/45.

I know the swingam is longer by roughly 2 inches. Didnt think it would take a 8 links longer chain.

The green tape is used for chain adjustment. The other side has one also. I got a really good alignment of the rear.

When I go to adjust the chain, I place a mark on the both tapes where the front of the axle slider is located.

Once I get the chain slack where I want it using the sprocket side adjuster, I place a mark on the tape where the front of the axle slider is now.

I measure the distance between the marks and then on the other side, place a mark on the tape that distance from the current mark.

I then just adjust that side back until the axle slider front  is at the new mark.

Your master link will look like this. You will definitely have one!

Is that a pic of the OEM chain or a replacement? I know what they look like I've installed a few.

I don't have one. 🤷‍♂️

I like the tape trick! I count flats on the adj. bolts.

I see your master link, but I also see your Vortex rear sprocket. Not OEM chain.
