    Are the bandit 250 ones the same? 61.5 outer diameter,26.5 inner diameter and 15 high. If they will fit without issues then sweet.

    Yeah the listing said they were for the bandit, in the threads I read that the Suzuki 250 ones will fit and i checked out the site to find an alternative but couldn't find the 3ln1. Maybe im just blind haha I'd like to find some here in Australia so ill try the locals before I order that listing you posted.

    So when the bike is running, are you saying that one or more of the slide's is not lifting when you give it a few rev's ?
    No need to replace them if they all lift ok.
    Do they all lift at the same time? eg Syncronised ?
    Were there any visible hole's in, or any damage to your diaphram's when you inspected them?


    Have you warmed the bike up to normal operating temperature and set all the mixture screw's to get the smoothest / highest idle speed ?

    Good, cheap and quickly delivered aren't usually used in the same sentence, lol

    Yeah all of them have little cracks in them so I've order some from ali express but they will take a month to get her so in the mean time ill try a temp solution by sealing the cracks just to at least get her home.
