Hi,

As the title suggests my rvf is running like a bag of potatoes which may mean the carbs need re jetting and all that jazz.

I've honestly got no idea what I'm doing in that area so is there anyone who comes recommended who may be able to help me out?

Cheers

Re-jetting? Very unlikely. Very thorough cleaning? Almost inevitably. You need to find someone who can strip, clean and rebuild the carbs back to factory spec - needles do not normally wear, unless they're flowing a lot of fine sand, and that's unlikely if your air filters are good and cleaned regularly.

Hi,

Thanks for the reply. I've done some questioning on various rvf forums and they are the ones who suggested a jet kit for the carbs.

Basically when on the likes of the 311 when your doing 120 and open the throttle the bike basically dies. If you dont dump the clutch and blip the throttle the bike will slow to the point it stalls in the gear its in. There is also a flat spot from about 7-8.5K in the rev range.

Hi Kempus, thanks for the info. Same diagnosis really, sounds like petrol starvation. Check the petrol lines, clean the filters and make sure they're absolutely free, air filter clean etc. If it's speed-related, then it's fuel flow, something is restricting it. Cleanliness is next to godliness!

Thanks again. I'll look at that. Couple of posts do refer to weak vacum lines which collapse due to age causing fuel starvation.

Get yourself over to Biker Banter forum on here, and ask the question. Someone will be along to help with advice on how to do it.

Or else wait for Chilli to see this thread, he is a mechanical genius with motorbikes.............

Thanks for the replies. I'm on the hunt for a vacuum hose and fuel filters but certainly if anyone still knows anyone with good knowledge in carb'd bikes I'd appreciate it.
