Rear Wheel Timing

[Bokerfork]

A few weeks ago I mentioned to a fellow rider that I was planning on getting some new rubber for the Feeg.

He mentioned that as long as I had the rear wheel off I might as well lube the rear drive splines.

He cautioned, however, that I needed to make sure I put the shaft back in with the splines aligned top dead center to the crankshaft.

Not being mechanically inclined he explained what to look for and, so, feeling adequately educated, I followed his instructions.

Ever since then the bike feels like its missing on one cylinder. Mostly at low speeds but regardless of RPM.

Realizing that the rear wheel was probably still out of time with the crankshaft I took it apart, rotated it 1 spline clockwise, put it back together, but the problem

persists.

Before I take it apart again and rotate it counterclockwise, I was wondering if anyone else has experienced this problem.

I did a Google/Forum search and came up empty handed.

Personally I wasn't aware of rear wheel timing issues since I've always ridden chain drive bikes in the past.

Any help would be appreciated.

I've never heard of this nor do I think there's a bit of truth to it. If alignment were key in a spline like this--they would have keyed it so you couldn't assemble incorrectly. There's also a number of gears in odd/even ratios between things that don't try and keep things synchronized. I'd wonder about the basis of your fellow riders claim and look at other more common causes of potential RPM issues.

FRIDAY FUNNIES. Goes right along with muffler bearings and winter air vs summer air in the tires. :yahoo: :yahoo:

Good one!!! Seriously, though -- look in FAQs for the links to maintenance sites -- both Warchild and Bounce have tutorials on the shaft spline lube and U-joint lube on their sites. A wealth of info on those couple sites. Just follow those and call ******** on any funnies your friends try to tell you that aren't mentioned there or in the Yamaha Service Manual.

For real???? That's like saying make sure the chain goes on at -this- link, not -that- one. Makes not a lick of difference. Especially since they rotate at different speeds. Five different choices of different speeds, actually!

The only things timed to the crankshaft are the camshafts.

You know, of course, that shafties can't do wheelies, right?

Funniest gawdamm post Ive read in weeks. Maybe months!

Pain pills are more funner with alcohol...

I'm jus sayin....

An sell that damn peddle bike before ya hurt yerself.

Don't be so harsh.

If you advance the spline timing by 2 or 3 you'll see significant increase in power but the resulting 'popping' on decell is annoying.

It's also not very effective at altitude.

Good advice. +1 for lube...

He cautioned, however, that I needed to make sure I put the shaft back in with the splines aligned top dead center to the crankshaft.

What he forgot to tell you is that this can only be done under the light of the full moon. Now you're completely ****** until July 15th - the next full moon.

...I took it apart, rotated it 1 spline clockwise...

Well this is where you seriously ****** up. Again, light of the full moon, walk around the bike 4 times backwards, swing the tire over your head twice, fart loudly in a southerly direction, and clap your hands together 3 times while standing on one foot. Only then will the splines copulate properly.

Any help would be appreciated.

You're welcome.

Wait wait.... walk swing fart clap...

****! phfttt...

Time out....

Type slower....

You have to be real careful with rear wheel timing. I had mine off the other day and when I put it together I just lined up the marks because I was in a hurry and did not make sure number one was on the compression stroke.

I guess I don't really have to tell you what happened next?

Sure enough I but the back wheel back on 180 degrees out. When I started the bike and it backfired on all four cylinders. You guys know how much power these bikes have, and even as it was stalling when I let the clutch out a little bit the bike backed into the garage door.

I will never make that mistake again.

You were really lucky that the engine didn't actually start running with the crankshaft spinning CCW resulting in 5 gears in reverse.

This is an easy fix and you don't even have to remove wheel or shaft, but it may take a few tries! Just pull in the clutch for a few seconds. Keep trying and eventually you'll hit it and everything will be perfectly timed!

In the automotive world -- this is an issue with drive-shaft u-joint alignment (must be correct).

This is why some FJRs are smoother than others -- Rear Wheel Timing...!

If you ever get to ride an FJR with correct crankshaft TDC/rear-spline alignment -- you'll know...

 

[Bokerfork]

Thanks to everyone for their help.

I've decided to just wait for the 2012 FJR which, Old Michael promises, will bring back chain drive.

Aligning the master link should be much easier.
