CB750 / Re: F2 carb bowl vent tube
« on: June 18, 2010, 12:52:42 PM »
Andy,

Maybe you are talking about a different tube if what you say is true, but I also had concerns about this on a previous 750F1 I owned and one of the brass tubes on that was missing and the hole blocked, the tube I am refering to is the one in the centre of the bowl and around 1 inch or so in length which come up between the float, if it is this one then for sure it is the overflow and mine being missing made no difference to performance, in fact if you look in the parts list the rubber tube that fits directly onto the bottom of the flaot chamber is even refered to as an overflow tube, but from what you are saying maybe you are talking about a different tube, or maybe your rubber over flow pipes are not going in the right direction? Just a thought, mine always ran fine without one of these tubes and as the float levels were good I never had any kind of leak.

CB750 / Re: Front brake piston F1

Nice bike Skoti, Since I have also had problems with the front calipur I thought I would throw in my expirence, the problem I had was pitting on the cylinder causing a loss of pressure, the strange part was that although air was for sure getting in, there was no leak so it was not obvious where, I fitted a new mater cylinder kit to no avial and DS did stock the cylinder in the past but it is now obsolete, however I found a guy in Southampton, John Oldfield, who sorted me out, he sells a repro one or an orignal, I got the repro one and it works fine, it is 41mm which I belive is the later one, but he has both....

here are the part numbers
Part Number      Descripton       Stock  Price (GBP)
45107-392-003  PISTON COMP.      1

CB750 / F1 Side panel madness!
« on: May 14, 2010, 11:00:37 AM »
When restroring my F1 I brought a set a new bungs for the side panel attachment points from DS, but they are so tight I managed to crack the LH side panel while removing it! I have since put some vasaline on each one to avoid the problem happeing again, but I am now in need of a replcement for the LH one which covers the electrical components, I got a DS repro one but it is not really a very good copy, I will be scouring the auto jumbles this summer but if anyone has one I would appreciate hearing from you.

Now there's an idea..... nice to know there are so many well preserved sulfer yellow bikes out there... well at least 3 anyway.

I am going to the MotoGP at Brands this year so maybe we could all line up there... 8)

WoooHoooo!!!!!!!!!!!!!!!! Yes you guessed it, I fixed it, well it seems I actually caused it in the first place, since I stiped everything down over a year back when I restored it, and surprisingly it passed an MOT then with no mention of the problem,  but for sure it had been there all along, I just hadn't noticed it, till this years MOT...... long story short in the connector box under the stearing head there are a bunch of connections, I had the feed to the RH Switch mixed with the turn signal buzzer, they are both the same colour code (Br/B) but one has a little yellow tag which had slipped up into the loom exit point out of sight!!! So about 15 hours greif as a result of my own cock up..... Thanks for your help Den & Yoshi got me going in the right direction, off to get the MOT finsihed off then I'm on the road..... :) ;) :D ;D 8)

OK, Insanity is looming now.....!!! Right I have now disconnected everything in the headlamp, except the brown feed to the 'P'/sidelight and the green ground for the same, still no light when switched to the 'P' position on the RH switchgear, but when I swith the indicators on either side it lights up! Despite the fact that now all the indicators front and rear are completely disconnected. I have dismantled, cleaned and checked out with the meter both handlebar swicthes and the ignition switch, cleaned every connector I can lay my hands on with switch cleaner but still no joy!!! Any further help would be very much appreciated.

Despite the danger of sounding like larry loner I feel compelled to ask.... Since I don't feel comfortable in a layby with R6/Firebalde brigade and I am clealry not welcome at British bike meets I was wondering if any of you guys meet up at any point to have a ride out and mull over the brilliance of our much loved bikes and compare chrome!

Wow those wheels look amazing, do you mind me asking how much the rebuild cost you, both wheels on my F1 are in need of the same treatment.... looking like a great job, good work.... I so wish I had a garage, rained off the driveway again today trying to fix my wiring!

Don't worry Eddie, I found all I need on their web site.....

OK More descoveries, brown and black in the RH Switch both have 12v all the time, until I switch ingnitiotn to park position at which point the brown loses the 12v, I have dismantled the switch cleaned and reassembled, and when I check the switch operation out with the DVM with no power switched on at ignition all checks out perfectly so I am pretty confidant the switch is good... also I noticed that when the RH Switch is in P position if I turn the indicators on the P lamp in the headlight flashes in time with the indidcators!!! ???

CB750 / Wiring problems with my 1977 CB750F1
« on: May 11, 2010, 08:20:40 PM »
Hi would appreciate anyones help here, I am going mad, I have 2 problems, first is that my tail light does not work, brake light is fine, and tail light works when ignition switch is set to park so I assume buld is OK as park is using the less bright filament as would the tail light, but not in run with 'P' or 'H' position selector switch on, the other problem is the sidelight in the headlamp is not working, same situation, when ignition switch is set to park it works, but not in side light mode!!!
I have found plenty of wiring diagrams but none show the sidelight in the headlamp unit or the separation of the tail and brake light. Any help would be appreciated.
In my headlight I have 1 large buld in the centre, which has 2 filaments, both are working for high and low beam, then there is another small bulb  below the larger one which has 1 wire going to the centre and then a ground, this is what I am refering to as the side light, and this is the one which comes on when the ignition key is in the park position, on the handle bar switch I have 2 positions one is labeled 'P' and the switch lever goes up slightly in this position into an inset part of the groove, and the other position is 'H', which assume to mean 'Headlight'. I took the bike for an MOT recently and the guy at the garage told me that the 'P' switch position should turn on the side lights, (the smaller bulb below the main one in the headlight). this is not working, and in fact to rear light does not come on in that position either, but it is also not working in the main position so that could be a red herring. ???
