PW that's sounds like she's coming good, responding well to some 'tough love". Suggest you don't bother complaining to the dealers, they have your money and the bike is going OK, so not really a problem for them. Bikes that sit for a long time can gum up a bit in the carbs, the ULP is not good for long term storage. regular use and fresh fuel will dissolve the gum build up, you could also consider putting some fuel system cleaner or fuel additive in fora couple of tanks to see if you can get further improvement. .Far as i know carbed bikes don't have O2 sensors. Also check your front/ back sprockets and compare with other bikes , it might be geared a bit high. I haven't ridden the 400s much, but have ridden with guys that ride them, its a popular "big bike" in Vietnam. I'm amazed at how well they go they seem to be a able to keep up with my 750 no problems at all up to about 120 km'hr. The acceleration seems brisk on them , but don't be frightened to give her some stick, any 400 needs to rev to develop the power. I would say she should do 140 no problems. Fuel consumption will never be real good, that's a lot of bike for 400 cc to push. at 21,000 km there's a lot of life left in a Honda 400, the engine will be settled in nicely now. That engine should give 100,000 + kms if serviced regularly.
As one of the other guys said just plug along, plugs, filters tappets etc, maybe check the ignition timing etc. The great thing about the honda v twin is it's user friendly ( difficulty in removing the rocker cover withstanding). I have avoided mechanics in general for about 30 years, just read the book and take your time. cheers simmo.

Thanks again for the advice. I'd been thinking about that O2 sensor thing and unless there's an ECU (usually associated with fuel injection) I don't think there is any point to the O2 sensor. I suspect you're correct and they aren't fitted on carburetted engines.

PW, just look on the exhaust pipes, do they have a couple of things that look like spark plugs sticking out of them? with wire attached, I don't think so. cheers simmo

Simmo, no O2 sensor/s, that's for the later fuel injected bikes. Derek, I have to ride a LAMS bike for my L and P period. Otherwise I'd be on a Yamaha 1300 cruiser or one of the big Kawasaki cruisers. The Yamaha 650 I thought I wanted was physically too small for me, bizzarely the VT400 has a bigger cockpit.

I traded the VT400 in this morning on a new Suzuki GSX650FU. Thanks for your help in the short time I had the bike.

hey mate, i brought mine as a first bike and i must say i absolutely love it. got myself up to 130km/h before i got a little scared and backed off, but it felt like it still had some legs in her. As for the fuel, the guy i brought it off told me to only put 98 fuel in it, instead of the regular 91. I've gone 3 weeks on the same tank of fuel and after 220km's, I've only just put her on the reserve tank, so stale fuel sounds about right. hope you're still having a lot of fun on it, because they are seriously great fun.

A friend of mine suggested it could be a restricter in the exhaust cos of the imported model. Or a not so common one is carbon build up in the exhaust. Both will affect the performance. Hope you get it sorted ASAP. Cheers

I think you will find that 'failure to disclose' is an actual law when it comes to motorized equipment such as cars and motorcycles. We have to supply an engineers certificate when a licence car dealer sells a grey import. You should check with vicroads if they should do the same with the bike. If they are, your meant to get a copy, if this didn't take place, they were hiding the fact it being a grey so they could ask local prices. I would be interested to see the outcome. Ask Sumoto motors in Flemington, they sell imports all the time.
