CB750 / Re: Finned exhaust clamps cleaning up & replating?
« on: Today at 01:08:12 AM »
I had a set done on my 500 and TBH they weren't great, the trouble is the casting is quite rough, especially in the recesses between the fins, they turned out ok but didn't last at all, rust appeared between the fins in a very short time. I intend to get them done again but next time I'm going to grind off all the fins, smooth out the metal so there are no casting spots etc and then have them chromed, the fins do very little to cool them IMO, they just look as they are supposed to look, in the 80s the fins started to disappear and the clamps just became metal rings in effect, which is what I intend for mine to look like, so long as they clamp the exhausts to the head they can look how I want them to look.

Just think on this Julie.

I just secured a NOS replacement from DS and he has a few left if anyone needs one. Looking at the USA SOHC  site that bearing was a hard to find item a while back.

 Unfortunately nobody seems to have the countershaft needle roller bearing at a reasonable price. 91023-286-016

I have a almost complete NOS gearbox including bearings and shafts, just need 3 of the gears to complete the entire box, they come up occasionally but not cheap enough for me to buy yet.

Nurse Julie, I appear to have contracted Dermatitis from using to many oily rags, should I rub an oily rag on it?

I'd agree with that Hairy to some extent but why does your premium go up when you don't make a claim, doesn't seem justified to me, in fact it sounds more like theft than the actual theft.

I used to do a lot of LED conversions for Vauxhall Astras involving inserting up to 46 LEDs inside the clocks in order to get them to glow at night in various colours, I had a lot of problems with light bloom but managed to fix the problem in the end with some creative thinking. Been a while since I opened a clock off an Honda but I seem to recall the light doesn't come through the faces of the clocks, illumination is done by light bleeding around the outside edge of the bezel and would account for the numbers etc being right on the edges with nothing on the inside where TBH very little light would reach by this method. That would mean the original faces were completely opaque and the problem with Lecrams is that they aren't. Easiest way around this IMO is to wrap some tinfoil  over the backside of the face to see if this stops the light bleed, if it does (and I see no reason why it shouldn't) then a stick on foil film can be applied and the holes cut out afterwards. If it's foil it's also resistant to the bulbs heat which would also help.

Just a word of caution here, even if you don't make a claim on your insurance, you MUST inform them about the theft if you have not already, otherwise when a blind woman reverse over your bike and doesn't stop, they wriggle out of paying any claim you do make!

Don't know why they'd need to know as if your not claiming what business is it of theirs, plus even though you haven't claimed they class the fact you've informed them as a claim which to me is so wrong is defies belief. Had a mate who did this, no claim but informed them and they put his premium up as a result.

There's a spare bike inside there in case of breakdowns.

CB500/550 / Re: Twin disc conversation master cylinder bore?
« on: September 13, 2018, 09:35:44 PM »
So are you saying that because the lever stays further out and it travels less because it's pushing more fluid that your hand is at a disadvantage because the fingers are extended and you get more force as the hand contracts ?

I did this mod many many moons ago and used a Yamaha MC, bore size was bigger but the lever had an adjustable screw where the lever meets the end of the piston, so you could adjust the lever to sit closer to the bars, TBH it felt quite hard which was a big change from the Honda MC which was always a bit spongy and had loads of lever travel, I did change the lines to Braided at the same time to stop the infamous rubber line expansion the early Honda fours were known for. I raced that setup for a few years, had plenty of feel without much lever travel, it could lock up the front wheel if pulled really hard but it didn't feel even remotely dangerous, in fact it felt safer as the braking improved tremendously.

Wouldn't that be LESS effort with a larger bore as your pushing a lot more fluid down the line for less movement, it would feel harder but require less effort to get more braking. Otherwise Honda would have fitted smaller bored MCs surely.

Or a slight design change, like the small lip to help remove the filter.

« on: September 07, 2018, 09:33:49 PM »
I actually ran one of my 500s like this in the 70s for a good few months, couldn't afford a new switch at the time. I routed the switch wiring back under the seat, drilled a small hole in the tool tray and mounted the toggle switch there, the bike was secure when I had to leave it as the seat was locked.

The 2 Z1s have consecutive frame numbers as well, oddly the engine numbers are hundreds apart, like they just pick up the closest engine to the frame.
