Price is high

F**k me its way overpriced for an unknown brand

And you still have the fuel issue as well with the bike,
I thought I could smell fuel when it was stalling, so maybe over fueling

Hi Tramp, thanks for this, been reading a french mash forum with lots of debate on the issue no concrete solution, up to page 27 at the moment....seems to lean towards fuel via the injector or idle valve......plot thickens

Looks a good deal, my bike will be a bit cheaper than that with some great additional extras included in the price.

Been looking for one so if you do please bear me in mind.
Thanks
Hope the hand heals quick without issues.

Hi all, not sure if the fueling issue is electronic or something else but here's some pics of what I did to my fuel cap which seemed to improve it. The brass plate blocked off the valve in the cap which I believe allows the tank to vent into the overspill space at the top of the tank and out of the drains tube, by the channel inside the cap assembly. I think if you remove the gasket it will allow water/ debris into the top of the tank space potentially causing issues in the future. Could be wrong but works for me. Cheers.

Normaly a vacum loc is just that so speed and fuel level wont effect it...also hot sunny weather is a vacum problem causer normally..my money is.on a bad desigh in fueling either ecu or a sensor somewhere...has anyone had the problem changed by altitude?..injection normally renders altitude asnagaist carb fueling...

When I was in morocco it did get worse as I went up in altitude,
