If you need turn signals I have a large box full of them! Welcome to a set for postage. I am NE of Toronto, just north of Mosport. John D.

[Schnell]

Hello John, thank you for the offer! I'm located in Uxbridge, just a pleasant motorcycle ride away. Any chance that I could just come by to pick a couple? Frank

See you Friday!

See you Friday!

Great to meet you, John! Thank you for the turn signal lights and for showing me your awesome bikes!

Different topic: I bought a new reg/rect combo unit to replace the 2 old original units. The new unit has a plug with one red, one green, and 3 yellow wires. That plug fits perfectly into the plug that the original old rectifier is plugged into.

My question is, what do I do with the 3 wires that are currently plugged into the original old regulator after I remove it? Thanks!

Okay, I'm a moron. What I bought was not a reg/rect combo unit, it was just a rectifier. It simply plugs into the rectifier plug. The old regulator stays.

Great to meet another Forum member Frank! Did you get wet on the way home? Waiting for some sunshine, so I can do a nice long run on the “new to me” Varadero.

Light drizzle for a short time. I only got moist.

Trying to sync carbs today. (see other thread for this topic)

Good news is that the carb boots do not test to be leaking. I sprayed them with quickstart ether and the rpm's did not change.

It poured here! Our road is like gravy, so my ride on the Varadero is delayed!

I just did some night time reading of your trip on your 75. That was great reading through it and brought back memories of the trip I did in 2013 from NH to San Diego on my 08 goldwing I flew from San Diego to NH to buy. I took 10 weeks to get back, 9,000 miles. 3 weeks in NH to get the bike and found a pop-up camper for the trip while there setting up the bike and camper while visiting with family and friends, then a week taking back roads to Wisconsin to visit my youngest son and his family for 3 weeks. He worked on a small 850 acre vegetable farm in the middle of the state, we went up north to spend a weekend camping and fishing with the grandsons.
When I left there I headed north to Rt 2 to head west zig zapping around the countryside on the back roads, down through the farm lands and through the Black Hills traveling many of the same roads you did, just a year prior to your trip. I picked up the coast road to head south from southern Washington to San Diego. 
I  had sold my K6 in 1983 when I was starting my family and hadn't yet gotten another 750 until 2015, but in the late 70s I rode my K6 through many of the same areas you did, I rode it cross country 5 trips with my hound dog on the back. Lots of great memories.
Now I have a K5 in Planet Blue just like my K5 I had bought new. I'm back to living in NH and would love to be able to ride cross country on my 750 if my back would allow the trip.....
I also have some projects in the works, a couple K4s, a couple K6s and a K8. I'm semi retired but am still being a carpenter to fund my projects.

Sorry to respond so late to your post. I must have missed it at the time. It's interesting to hearing another enthusiast's story. Travelling with a dog is even a better story than travelling alone or with a girl.

Back to the project thread, now that the carb issue is resolved.

I mentioned 2 jobs I was hoping to do today: checking if obnoxious exhaust has a baffle and replacing steering head bearings.

So yes, the RC exhaust has a baffle. I can only imagine what it'd sound like with it removed. I'll try that sometime. I think I can wrap some glasswool around the baffle to subdue the exhaust sound. Will give that a try too.

The main job today is replacing steering head bearings. I'm almost 1/2 way there. It's a messy, involved job.The fork stanchions were quite rusted and not too easy to remove. I've also discovered why the front brake isn't very good: oil from the fork seals.

Ordered new seals from the closest Honda motorcycle dealership but they won't be in until next Tuesday.

Frank….. next time go on line to Vintagecb750.com. They deliver in 48 hours to my place, you might get it quicker. They also sell a fibreglass mat blanket, specifically for wrapping around that baffle. I wind it around a few times and use stainless wire to wrap and hold it. Will quiet it down 40-50%.

Great to know! My last order was from 4into1 from the US. I had to pay $50 duty to pick it up, after paying 4into1 for USPS delivery.

The bearings are installed and bike is buttoned up as far as I can, waiting for fork seals. I only misplaced 1 item in my messy work space: the plastic ring that fits in the fork ears right below the upper triple tree. It's got to be somewhere in the garage. I broke 1 brake switch wire as everything was hanging loose. Easy fix.

Frank….. FYI. Vintagecb750 is just outside Kitchener. All you get dinged for is GST and delivery charge if the order is under a certain amount.

[Schnell]

Thanks John. I'll use them from now on as my first choice. Cross border shipping is a crapshoot with extra charges.

[BenelliSEI]

Give them a try. I like their stuff and the quick ship is great!

[Schnell]

$20 for fork seals from vintagecb750, $50 from Honda

[Schnell]

The fork seals came in yesterday afternoon and I installed them today. And put the bike all together. Hopefully when I go out to the garage tomorrow, the new seals haven't leaked.

I’m sure they will be fine. Well done! Let’s see some pics of it back together……

[Schnell]

Pics tomorrow.

Question: Is there a red layer on the outside disc brake pad to indicate excessive wear and time to replace?

Yes

Thanks Stu. Going to give vintagecb750 a try.

Here's a quick garage pic.

Did you get “the book” from Rick?

Did you get “the book” from Rick?

Yes I did! Thank you for the heads up.

There was no pool of fork oil below the front wheel on the garage floor this morning, so that's good. I took it on a bumpy ride around the block. One of the fork tubes was more moist than the other but there was no pooling above the seal. I somehow lost the dust caps above the circlip. The gators are on the tubes but not attached at top or bottom so I can check for leaks.

The bike didn't run as well as last time that I had it out, especially in the first 1/8 turn of throttle, but after I got home I found that I had failed to completely disengage the choke. Hopefully that was the issue. Header temps ranged from 145 to 217 so fine tuning is still needed.

Here's a pic from today.

[BenelliSEI]

I don’t think there are dust caps above the clips, just the boots? Did you wrap that baffle or still annoying the neighbours? Looking good!
