Re: Re:

Hi, carb is a Mikuni VM26, elbow as per attached photos, I guess it does provide some restriction. Amazing that it can make a difference to carb performance! https://uploads.tapatalk-cdn.com/20201013/59958d089a20a68f875c1ed907051aa2.jpg https://uploads.tapatalk-cdn.com/20201013/f51c226d237b06a7ab1b...

Stainless bridge piece fit.

The stainless bridge piece I got from Vietnam required some grinding to fit and even then doesn't come forward enough to cover the gap with the legshields. Wondering if this is just a bad product and a replacement from an alternative source would solve the problem and be a straightforward fit ? http...

Re: Re:

So today I tried putting on an "Atomic" elbow designed for a remote filter, but with no filter. Normally starts first kick once warm, with the elbow on it was very difficult to start. Elbow is off again and still wiping the petrol off the floorboards after every ride [emoji2] Sent from my SM-G985F ...

Re: Won't start from cold unless bump it.

With the choke OFF, if you lift the outer gently at the carb end, how much free play does it have? In other words how far can you lift it out of the adjuster before you feel it lift the choke?
