Should anyone have persistant issues with the electric choke, Dellorto also make an electric to manual choke assembly for the PHVA carburettor. However, would you really want the faff of trying to get your hand in to what is already limited access to the carb?  |

I agree a manual choke lever mounted on the carb would not be easy to use,

Update
As far as I can tell I have now fixed all of the wiring defects, but it wasn’t easy as the wires at my ignition switch were different colours to any diagrams I could find on the fb page, however this was due to a previous repair, the lilac wires which provided power to the brake light switches were both quite frazzled, possibly due to one of the brass bodies shorting to earth, I can turn the starter by just shorting the two terminals and pressing the starter, however it doesn’t start unless I put a rag over the carb intake to seriously limit air flow, then it starts easy and the rag can be removed straight away and it will idle or rev easily so not sure what to do about this issue, the carb enrichment device seems to work fine and the jets are all clear.
I have ordered the brake light switches so will get them fitted and hopefully get the headset back together, nearly all my wiring problems were in the section from the horncast upwards both burnt and fraying damage.

Hi Ian, Good to read about your update. Not surprised to read about the frazzled wiring - no doubt possibly due to the incorrect fuse being fitted at some point. Problems with ignition switches appear to come up regularly, the rule of thumb is the 10th post by "italjetlewis" on the following thread: italjet.proboards.com/thread/43/velo-ignition-switch-wiringAlso see my reply 12th post down about my ignition switch with 6 terminals! Personally, I gave up reading information posted on the Velocifero FB site long ago, as there was (in my opinion) so much misinformation both technically and even down to factory paint colours. However, the factory did slip up with the wiring on one occasion as I have reported elsewhere on this forum. This related to the triangular block connector that feeds power to the rear lights. The connector is idot proof, in that it can only be engaged in one position. However, that didn't stop the wrong coloured wires being fitted in the wrong order on one half of the connector block. At the time I couldn't be bothered to check which block was incorrectly fitted - and despite all this, the lights still functioned correctly! If it aint btoken - don't fix it!! |

My cold starting issues persist, in an attempt to verify my auto choke is not working, I removed the choke unit and blocked the hole with a rag, it started straight away which leads me to suspect that my choke is in the off position all the time.(needle extended)
The length of my brass needle and brass needle holder is 20mm when cold, so it looks like my opinions are new choke unit or manual choke, the manual choke is probably going to be a faff but obviously very reliable, the new auto choke seems expensive.
All help and advice appreciated
Ian

Nice one, thanks for the link, much cheaper than the other ones I was looking at, mine is the one with the rectangular connector.
I have had no joy obtaining the v5 from the previous owner so I am going to have to apply to dvla for one using the frame numbers I can make out, I do have the reg plate so that is a start

unless I am mistaken, I think I came to the conclusion when I had starting problems, that the de energised position for the choke is that it will be operational, thus allowing the machine to start. So as I see it, if the choke solenoid has failed - this should not prevent the machine from starting. So if I understand it correctly, unless the choke has failed in the 'ON' position where the solenoid is energised, (very unlikely)then cold starting problems as a result of failiure of the choke seems to be quite unlikely.

New choke fitted and it works a treat, still to take it out on the road and test properly but starts and idles fine from cold now
Cheers for the help and advice
Ian
