Honda-SOHC

Hi Brian

Thanks for the kind comment

Got the cooler and sandwich plate from here

https://www.d-mengineering.co.uk/en/

Don’t bother with the braided hose kit that is offered as in the end it was easier to buy all the separate fittings and a hose kit from eBay and make up the required  hoses to suit my final cooler and sandwich plate set up / position as both my sandwich connections as you can see are at six o’oclick and then I have used two 180 degree bends to return the hoses back up vertically to the cooler

The kit I used was 3/8 (6AN)



Also did not bother with mounting brackets as thought they were a tad expensive so made a cooler mount at work which I think was much better

As for temps I fitted this as a pre cursor to the 460 engine I am current building as I was told by DM that oil cooling on the standard engine is on the limit so a oil cooler for a big bore engine was a must have

Best wishes always Al

An interesting point of note is for the Yamaha  RDLC the 250 single disc is fitted with a 1/2” Master cylinder and the 350 twin disc a 5/8 M/C but for better feel and less wooden brakes it’s common practice to swap the 5/8 unit to the 1/2 unit

Yes you get slightly more lever movement due to the reduced swept volume of the master cylinder with the smaller bore but the braking is much less wooden

Incidentally for my RD I am running a 14mm M/C but also have two four pot callipers too and floating discs so much better than the original 1 pot sliding caliper per side acting on a solid disc



And on my CB400F twin disc conversion even though I have a extra caliper I have kept the original M/C and not needed to increase my M/C bore size to allow for the extra caliper



Best wishes Al

Not mine either, that looks really garish. Sometimes less is definitely more. I am sure the original Harrier was far more restrained.

I guess its subjective but it looks well tidy to me - not sure about the blue bits might have been nicer all in orange.
Methinks it needs Alans rear disc. upgrade.

Bit to bling for me

I like a modified bike but done in a subtle way.




Think even my rear disc conversion would get lost in the styling

I've fitted a less tight throttle spring on my 550/4 Mongrel because I found it a bit hard work after a few hours riding, it works a treat. I had to retain a bit of tension though as I don't have a return throttle cable fitted to this bike but this snaps back just perfect.

Hi Julie

May I ask where did you source your spring from please

Would like to use a lighter spring on my CB400F as starting to do longer rides out +100 miles so would like to lighten up the throttle a bit if possible

Many thanks Al

Hi Al
I sourced it from a spring parts bin in the workshop I've no idea what model Honda Four it came from, all I can remember is that the spring tension was a little less than the one I had fitted and overall it was a few mm longer.

Ok thanks for the reply

I will measure mine and see what is out there

Thanks again Al

Hi all

Due to me cracking the original tail light lens and having to buy a complete unit to source a genuine Stanley lens got a brand new tail light unit minus the lens

They retail at £32 plus post on DS site so looking for £25plus £3 post

Any questions please ask

Best wishes Al

On the wall

Found this one in a box of bits at work that is older than me

Doesn't look bad to me, and if running/responding ok, no pinking etc, then appears to be all right.

If you're concerned about plug temperature, then you can go up a number (NGK + #) to get the tip running slightly cooler.

Thanks

It was just a check as after the winter lay up it refused to start and just flooded / had wet plugs so as a precaution did a normal carb clean and rebuild and after four new plugs fired up ok but like to do a plug check just to confirm all is ok and plugs seem cleaner than my check last year when I rejetted to 38”s for the pilots
