I'm assuming that the fuel pump below the tank is just a gravity pump.
I'm having a hard time starting my bike when cold. I use starting fluid and after a few minutes, it will idle on its own. Since the bike is carburated, i'm assuming that there wouldn't be too much pressure from the pump?
Bike's an '85 VF1000R
Any ideas?

Hi kfzmeister
I just had the same problem with my 86, pump was gone,You can still get them in the US. I have seen a German use a Bosch 7.21440.51.0 pierburg pump, that you can get on Ebay. He used it on another Honda.It will not run right without. Seems OK. Hope I could help.
Kind regards
Torben :wink:

I am having similar issues with mine which I haven't investigated yet. In my case the bike has stood without running for 20 years and so suspect the carbs are gunged up.

Bah! Just get rid of the pump! Running gravity feed straight to the carbs has worked perfectly on my VF's for years. One less 25 year old part to fail!

I see, ...no real need for the pump then? It did seem like getting the fuel to originally flow from the tank was not very easy.
I'll give it a try.

I've not had any problems. Give it a shot and you just might like it!

I had the carbs off and cleaned them out, so will need to try and synch them. Perhaps this is contributing to my dilemna. I know they are off a tad. I did see a link to some instructions, so will check out when weather gets a little warmer.
BTW, what is a set of front forks worth?

Thanks for the help,
Pete
