Took the spacers out... now I can actually compress the forks with my body weight. I think it was just too much preload.

You work fast I've been bumming around lately due to longer work hours, I need get my forks back together soon.

Wife out for the night and sleepy kid in bed before 7PM.

Looks awesome!

Gorgeous!

Removing those spacers worked wonderfully! I can now feel the road beneath me, but all the clunky feeling is gone!

Vibration in the handle-bars is also much less now.

Put on a BT45



Next time I do the rear tire it will also be a BT45.

Fitting my new gas cap seal for the second tank, I couldn't remember if all the disks go into the seal. I was about to make a post, then I remembered the great photos someone took before...

And lo and behold...

Remember, when you take the old seal off and install the new one that all the "disks" go inside the new seal.

Thanks, Matt!

Rigged up a charging port for my cellphone/gps while on longer trips. I'm going to be doing some motocamping in a few weeks and I don't want to lose battery!

Also re-tightened my new steering bearings. They had settled in over the first few hundred KMs, so I snugged them back up. Went for a ride. TOO TIGHT. I was fighting the bars through turns. Didn't feel safe! Came home and backed the adjuster nut off a bit (1/4 turn or so), then went for another ride. Smooth as silk! When the front end is raised and everything tightened, I can get the bars to swing about 1-2" before the weight takes over and it swings to the full lock.

For those adjusting this nut after installing the tapered bearings... make sure you make the adjustments with the wheel DOWN. I found adjusting the special nut with the front end raised didn't let me feel when it was "too loose" because the weight of the fork and wheel was pulling down on it.

Set initial tightness, tighten the chrome lock nut, raise the front end, check for tightness, lower back down, tighten pinch bolts last. Repeat as necessary!

Just ordered everyone's favourite transistorized ignition module!

Thanks Mark!

I had a fun day yesterday...

I was getting lots more rattle than normal at idle, so I decided to check my timing and do a vac sync. Simple, right?

This is how my day went:

Static check of timing. 1-4 OK, 2-3 too far advanced. OK, adjust it! It was already at the end of the adjustment plate so I have to close the gap slightly to get it just right. Turns out the reason it had slipped for where I had it perfect before was because the hole for the little screw to tighten the points was STRIPPED. DAHHH. Easy fix though... drilled out old hole, tapped to M5, cut a nice short M5 bolt, and snugged up. Nice fix. Proud of that one. I'll get another points plate eventually. Timing is now bang on.

On to the vac sync...

Everything hooked up all set to go. I noticed as I made adjustments that the vac gauges didn't change very much, and #2 didn't change AT ALL. Started poking at the #2 rubber boot, and upon further investigation and DISASSEMBLY...




All the boots were at least somewhat damaged, two of them looked like this.

These stainless band clamps are great, but I stupidly used a socket and ratchet to tighten them instead of just a screwdriver. Tightening too much pulled the super soft rubber off the spigots and started breaking the rubber.

After reinstalling the OLD, slightly hard boots, everything vac synced perfectly. Bike runs better, too, with no big sucking vac leaks!

LESSON OF THE DAY... DON'T OVERTIGHTEN #$%*.

Also I love my wife and how understanding she is...

Trade you?

Wait, I'm first!   Have you seen a pic of her??

[evanphi]

Oi back off!

[calj737]

I was offering a trade for an unknown,highly praised woman in exchange for a slightly weathered, bitter, mother of 4. Seemed a pretty fair deal in my book?    Oh, by the way, my wife does ride and comes with her own bike (just to sweeten the deal). 

[evanphi]

My wife rides with me! we both fit on the 750 just fine

She gets her weekend for yoga training, i get my time with Rhonda.

Why buy the cow if you can get the milk for free? Not a description, just a saying.

[evanphi]

OK she won't be so understanding if we keep this up.

Something special came yesterday! Going to install tonight.

Creative locations for mounting without disassembling too much are welcome. I'm thinking between the battery box and rear fender, stuck to the fender with some industrial velcro.

I had mine under the seat last year but moved it this season. At the risk of getting flamed, my 550 has a deltran lithium battery which is about a third the size of the stocker. I got some really good dense foam 1" and made two pieces about the size of the tray. Then I cut 1/2 pockets in each one the size of the hm ignition and that's where it stays, surrounded by foam under the battery. I don't know if it's ok there, but it seemed like a good idea. The only down side is ventilation, but it's a sealed unit anyway so....

I'm not sure why you'd get flamed for using a lithium battery.  Many of us do, especially to save weight or for space constraints.

I've had 2 lithium batteries die on me. When voltage falls below a certain level, they will not recover.  Period.  For me, this happened at inopportune times.  I have since gone back to AGM batteries, except when I am trying to save weight and space (e.g., under a seat hump), in which case, I have used Shorai's, which seem to have decent quality control.  Care must also be used to used; some lithium batteries (anti-Gravity and Ballistic) have burst when old reg/rec units have shorted.

I don't care much for lead-acid batteries.  I can see their use in faithful restorations, but the AGM's are not only lighter but zero maintenance and you can mount them sideways if necessary.

Dang, Don. Your signature is getting longer than your posts 

[Lostboy Steve]

Yeah I meant flamed for putting it in a confined space without ventilation. I have had this deltran for 2 years now and even left the ignition on overnight once (oops) and it's still been good.
