Welcome to the fold, what country are you in? Asia is a big place
That naked 400 is a rare machine, a few came like that as standard and were used for rider training in Japan with a few modifications. I have only seen one ever in the UK. There should have been a small fuel filter in the fuel line as standard.
Your leak sounds like dirt in the needle valve and drain the carb float bowl normally clears it.
The red Suzuki with the red cam cover is the one with variable valve timing, not to many of them over this way.
That one looks very clean.
What model is the black Suzuki?
Hi Unfazed, nice to meet you due. I'm from southern part of China, Wuzhou city. Naked Fz400 is mod with Yamaha Xjr400's panel, inicators, bar and mirrors and so on... It's very popular here, it's beacaus the weather here is warmer than Europe, it will easier to get cooling when you getting nake.
it won't snow here in the winter.
Yeah, the red Suzuki is GSF-250 A.K.A Bandit, and the variable valve timing we call VC, when over about 7000 rpm it works with higher camshaft to make more powerful output, it's something like HONDA's VTEC.
And the black Suzuki is EN-125, I think it's only sell in China. 125cc bikes is very usual seeing here, over 95% of bikes are 125cc.
