Got her today

FYI-MY bike is 2.5 years old battery was replaced under warranty once it is approx 6months old I don't have an RSA right now.

Went for a100 km ride today battery was struggling a little will not lie as it powers maddod alpha and vaishnu headlights if I on off 3-4 times continuously it used to struggle or with all the lights on if bike stalls and turns off then it struggles to start the self but eventually does it with flickering of lights.

So back to the story went for the 100 km ride went really smoothly and you would assume the battery should be charged right there was no problem on the road on the way back went into a dhaba for lunch when I came back bike was giving no response at all initially i thought some wire may be loose or something opened the battery box tried shaking the wires and all nothing.

Was really confused in middle of highway what will I do with a 240kg bike(with accessories) thankfully a battery shop was there just outside the dhaba pushed the bike there and asked hime to check he measured the battery with multimeter said it is dead need to change it with a new one .

After thinking and although it had 48 month warranty i decided to change it and also gave the battery as replacement (100 rs cashback) total battery cost-Rs 1763. I decided if I buy new battery any ways old one is worthless and I will have no use of it I don't have any other big bike to fit it and it had only 1.5years left eventually new battery (amaron) gives 36 months so changed it did not want to get stuck again so got rid of it once and for all. Last time when the battery was changed same thing happened but thankfully i had RSA that time.

Buddy gave me his old cb750k couple summers ago and it had sat outside since 2018. I recently started paint project of the tank and soon to be side panels. I still need to wet sand it of course but overall proud of the outcome. I did have to go back and repaint the black cause I put the tape on too soon as you can tell in this video.

Couldn’t decide between colors. After splitting them down middle I didn’t like how clean the line in middle was. So as final product I did stripes on each side.

Debating doing very then white lines in between the colors but can’t make a decision on easiest way that isn’t buying a can of white paint. Any tips appreciated for that idea?

Picked this up a few hours ago, I’m excited to get to ride it when the roads dry up. Runs great, everything works, rebuilt carbs, forks serviced.

I was fortunate enough to hit the Honda demo yesterday, and was able to ride the CB650R and 1000 Hornet SP.

Even though the two (650 and Hornet), as far as ergonomics go, look very similar, for some reason I found the 1000 much more enjoyable to ride. I like the way the 650 looks more.

Of course the CB 1000 F was not available to test ride, but it’s absolutely beautiful and I’m wondering if it’s worth going through the loan approval application so I can take it for a spin.

Between these bikes, what are your favorites as far as economics and performance go?

I’m thinking of getting a Honda for the first time, as a Triumph guy this is a new realm for me.

I bought this bike, as is, roughly 3 weeks ago. Since then I fixed the battery ground to start, then moved onto all new bearings, front wheel, rear wheel, triple tree. I installed a new clutch, oil change, and even got the front forks professionally rebuilt. As you can see in the video, I have smoke coming from everywhere except the exhaust it seems. From a visual inspection, the head has been removed prior to me owning it, as whoever did it added some gasket maker onto the valve covers and heads.
Bike runs amazing, other than one things. Number 2 carburador spits out small amounts of fuel only upon accelerating. Not enough to cause a puddle, but enough to see. Other than that she has a very small backfire usually upon cold starting idle. Any help would be useful!!

‘71 CL350 with three additional lower cases and crates of extra parts. Identified no power getting to the headlight bucket even with a new battery, ground tests, and fuse so ordered a new harness. We will see if that clears things up. Have a Charlie’s digital ignition on the way. The exhaust has some holes so I plan on patching those up. Any other suggestions?

Bike now leaks gas from carb 1 :( but at least my front end is almost done

New slip on, sounds and looks way better than the stock one, and also the LCI slip on that I installed first.

Hey y'all. Newbie mechanic here, probably asking a dumb question but it's just one way to learn, so here goes-

I was going through some maintenance today on my '74 Honda CB550 and I got to the part about adjusting the cam tension. Seemed pretty straightforward until I was told to expect a spring-loaded adjustment screw that would find its proper place once I released the nut holding it tight. I had cylinder 1 in the right position, got the nut released, and then...nothing. I ran the screw in and out a bit and no magic spring action. I wanted to ask: can that spring wear out? Is it not self adjusting because there's no spring tension on it? And if I unscrew it completely am I screwing myself by undoing a connection inside that I would have to tear apart the engine to get back to? If you read this far down, please know I appreciate your time, and any advice is welcome and respected.

Hi all,

I'm restoring a 1986 Honda CBX750F (RC17) and I'm stuck on the fuel petcock. Hoping someone here has been through this.

What I've done:

- Rebuilt the vacuum petcock with a Tourmax FCK-1R kit (new vacuum diaphragm and O-rings)

- Replaced the tank-mounting O-ring (OEM 91305-MC7-000)

- Replaced the fuel hose from the petcock outlet to the fuel filter with a new one. The new hose has a slightly different diameter from the original.

The petcock has 3 outlets:

1. Vacuum line to the engine

2. Fuel line to the fuel filter

3. A third outlet that isn't connected to anything, which I've capped

The problem:

When I crank the engine, fuel leaks out through the capped third outlet and the bike won't start. Fuel only comes out while cranking, so the vacuum seems to be opening the valve, but the fuel goes out the wrong way instead of reaching the filter and carbs.

My questions:

- What is the third outlet for on the RC17? Should it be capped, or is it supposed to be connected to something (second feed, return line)?

- Could the small diameter difference of the new fuel hose cause a restriction that pushes fuel out of the third outlet?

- Is it possible I assembled the diaphragm or an internal gasket wrong during the rebuild? Anything specific to watch for with the Tourmax kit?

- Any tips on priming the carbs once the leak is fixed?

Thanks!
