Boing Boing Boing - Bouncy Front End

Gents,

Yesterday I met up with FJR NewOn2 (Steve) from near my area. He wanted me to take a look at his FJR because he's experiencing strange handling characteristics. He bought the bike used. It's a 2014. Pretty bike.

It's been a long time since I've my my big Feejies, so I'm here to seek counsel.

The tires are PR4s and in good shape. The pressures are ok and he's not a big guy. The steering head bearings feel good.

He said that when he got the bike, the clickers were all maxxed tight and he thinks the previous owner may have been a big boy. As he noticed some wonky handling, he said he put all the clickers back to stock. That's what I would have done, too.

When I threw a leg over the bike, I could tell right away that the front is so squishy and bounces almost like a rocking chair. The back is set on soft, but feels pretty firm. The front feels bouncy soft. When I rode it around the mall parking lot, it requires a hefty PUSH to get it to turn, and then it's fighting you to stand back up.

Yeah, that's not like any FJR I remember. My son thought the previous owner may have lost oil from the fork or something, but the bike doesn't look like it's been abused at all.

Now, I suck at suspensions and I have guys I depend on for track and dirt... but for street I've used Traxxion Dynamics and they are good at setting things up and shipping 'em to you.

So, as I look for a local suspension guru to send Steve to... can anybody think of some tips for him?

Thanks!!

First determine exactly how many grooves are showing on the preload adjusters. I'd start with about 3 grooves showing. Then I'd take a hard look at the compression and rebound damping settings. I guess this is what you referred to as the 'clickers'. If the forks are leaking it should be quite apparent after a close inspection. Repeating bounce from front end after initial compression of forks is a sign of to soft of rebound damping at the top end. The lower ones adjust open/close to set the resistance to sudden compression at the lower end. You test this by simply applying the front brake and thrusting down on the front end. Just for initial feel of course. Only a test ride can confirm final adjustment. I've actually gotten pretty good over the years just static adjusting by feel and observing how the compression rebound behaves.

Fork springs are progressive, squishy if preload not cranked almost all the way in, if not all the way (good for say 175 lb. rider).

Damping should be set at 8 clicks out to start, not the squishy Yamaha 12. Rear shock better at 7, eventually likely end up at 6 clicks out.

Doubtful he lost fork oil unless a seal is leaking, but you'd see that all over the front brake pads/rotors if it did. Loss would be minimal anyway, it always looks worse than it is. Certainly didn't lose enough to affect function.

Thanks for that, RaY. We'll look into that.
