Spot on (pardon the pun) they were to help give beam direction in old version lamps.
They're not of any real use now, accept to give a certain 'Marmite' appeal, personally I like Marmite.

I've modified and fitted a P700 Tri-Bar headlamp, the peak gives a crescent effect that actually spreads the beam...may stick with it, juries out.

Hi mate,
Yes a good first trip, just need to downsize the main jets to cope with Weseco's.
And yes I did see and drool over your 400-4, looks fresh out the crate, a credit to your many hours in the man cave.

As to the negative post about the 60,s look, "what's the point"?.....if that was a serious question, there is no real point other than a homage to the original cafe racers and a slap in the face to the American influence of pretty paint and bling. I didn't think this site was for the purists!

Hope to speak at Twyning, you know some of the BSB boys are attending.

LYNX....That's my Bike mate, it was our first run out this year.

It is an amalgamation of some of my old bikes and bits.
Headlamp peak, bacon slicers and a lack of shiny paint, it's a taste thing, most of it's even functional.

The engine is basically now race spec (other than keeping the alternator / charging system) and she handles, stops and goes like #@%$.
Oh and the front brake is a GT750J 4TLS.

Hope to chat at Twyning

Ow Do Lads,
Your welcome is much appreciated.

Bryanj: Whenever you fancy a meet up for a brew and chat just let me know, I'm in Bishops Cleeve....You didn't come to the Apple Tree in Woodmancote for last Wednesdays bike meet did you? Over 400 bikes last turned up.

K2-K6: The pic is of a run up Prescott Hill Climb a couple of weeks ago, I rarely take the old girl on track days but good fun though.
When I work out how to condense the pics I have, I will post some spec details.

Cheers
Dave

Bryanj,

I historically change the oil every 1,000 miles max, however this rebuild hasnt done that many miles as yet.
I notice that this semi synthetic stuff is much thinner than straight 10/40, oil I normally use by the way.

I will drain off the semi and refill with millers and post the results.

Cheers

CB750 / CB750 F1 smoking like a b*****d.

Hello Lads,

Just joined your site and I have question to kick off with.
My overbored CB750 F1 with CR oil cooler has started to smoke like a B****d.

My concern is that the smoking is down to wet sumping due to fall back from the extended, external oil line from the return outlet to the oil cooler. I say concern, that would be the best scenario I think. Either that or it's seepage from the valve seals.....although I did replace them in the rebuild.....Gut instinct says its a bad seal or valve guide.

Relevent spec: 836cc overbore / Dyna S ign / CR carbs / Accer coils / rebuilt engine by me 8 mths ago (I take any blame) / CR oil cooler and extended oil lines / High flow headers and pipe / non standard oil box..etc....

Starts first kick then aprox 30 seconds later comes the heavy blue / oil smoke which clears when warm, then she runs smokeless and very strongly as a rebuilt engine should. Stop for half hour or so and same problem.
I note that there is aprox three quarter of oil in the sump, never known what amount should rest there?

I had a similar problem with a Ducati 900 Bevel, turned out to be a combination of valve seals and crap valve stem tolerance.
Oh yes, it started smoking just after a routine oil and filter change, I used Silkolene semi 10/40...relevant??

I will have to work out how to reduce the kb size of my build pics to show engine detail.

Thoughts welcome...Cheers.

Hello Chaps and Chapets,

I'm new to the collective and looking forward to talking all things SOHC4.
Although I have had Honda's for the past 34 years there are times when I think I know bugger all and rely mostly on instinct.

You guys come highly recommended and I'm sure your collective knowledge will help me overcome some moments of senility in the man cave.

Cheers
Dave
