    Morning guys, I'm sorry for asking the same question again about my 1995 Trident 750 but I need an answer before placing an order. The question is: Is the fuel cap as fitted as standard a Vented or Non Vented type!.
    (World of Triumph list both types).
    Many thanks for the great info I have received to date, much appreciated.
    Can I through the forum say thanks also to "Sprint Manufacturing" for their help in supplying parts for my bike, thanks again.
    Cheers,
    Tony.

    Assuming both fit, I would go vented. Do you know if both fit, that is the question you are asking?

    The early T300 models were vented caps , as the fuel isn't pumped out , it's gravity fed to the carburetors ! A non vented cap would case a vacuum and then the fuel wouldn't flow well enough and bike would suffer fuel starvation , it would run for a few minutes/miles and stop !!

    The cap on my Trident is vented. I know this because it 'sings' as the temperature rises/falls and the air in the tank expands/contracts, forcing the tank to breathe. Sounds quite melancholy sometimes.

    Previous thread on the cap issue would answer your 1st point.

    People replying to this thread are not necessarily going to know about the previous one ...i didn't so it obvious someone is going to mention the state of the tank...not very friendly!:rolleyes:

    I'm not sure if you possess a sense of humour Tony, but if you do you might want to engage with it when you come on here ;);)
    You will find an awful lot of useful information given to whatever problem you care to post, but interspersed with that may be the odd flippant comment or observational piece :rolleyes::rolleyes: it doesn't make the relevant posts any less valid but the forum keeps things light hearted but informative :):)
    If people feel they are just going to get slammed you might find the useful stuff dries up :worried::worried:
    If it doesn't suit just scroll on by but try not to be rude to people who post on your threads, we all like to smile once in a while :cool::cool:
