Re: NH 350 Chain oiler puzzle.

Jim,
This is a photo of the oiler from my Sq4. I think yours should be similar. I agree that blocking off the hole and using a modern chain lube product is a good idea.

Re: Can you help me identify this speedo

Hi Bob,
Welcome to the Forum. You had better send a prayer of thanks up to your late father. That speedo is rare and highly sought after i.e. worth a lot of money.

Re: Sq 4 MK II (Solex) Reluctant to cold start

Paul,
That 40 weight oil should be O.K. for 50°F temperature. To eliminate the oil as a cause of your problem why not change what you have in there for some synthetic 15W-50? What lubricants are you using in the primary case and gearbox?
Regards, Chris

Re: Sq 4 MK II (Solex) Reluctant to cold start

Also, because when hot, the carburetor drips a bit of fuel if left on the side stand, I have taken to always storing her on the center stand, and running the fuel bowl dry at idle upon shutdown. Hello Paul, What happens if you leave the float bowl full? There should be no leakage if the bike is on ...

Re: Wheel spokes advice required again....

I don't think that, as a whole, anyone has probelms with spoke lengths judging by the lack of replies quoting similar problems to mine. Hello Alan, I certainly had problems with rims and spokes from Central Wheel/Draganfly but I've been a bit busy to reply in detail. I've had absolutely no problems...

Re: help sq 4 wont run

Hello Kevin, Congratulations on taking the right decision. I wish I was in Malaga right now as the forecast here calls for 14" of snow today. If you are patient and persevering you will be able to take that motor apart and put it back together without insurmountable problems. There are many peo...

Re: help sq 4 wont run

I have owned the bike since 1990. It had been in storage in a shed in yorkshire since 1970?? I ran it last in 2002 Hello Kevin, Are you saying the motor hasn't been opened up to clean the sludge traps since the 1960's, if ever? If that is the case I would advise not to even think about running the ...
