Hi everyone,
first of all a thank you to all of you who posted helpful information about the VMax 1200. I learned a lot, but obviously not yet enough as I have an issue with my 2005 VMax I can't get figured out.
Here the description of what it does or not does and after that a description of what I did so far.
The bike didn't run much in the past 2 years, but even before that I noticed that issue of a sluggish running engine already. Within the 2 years i let it run once in a while a drove it a few miles to keep things moving. I stored my bike with a full tank and had sea foam in it while it was stored. Even after a long time of not using it, it always starts up right away, but once it settles in to run without choke, it feels kinda rough, the throttle response is not crisp, and the left exhaust smokes more than the right one. IT doesn't stall though. Also sometimes I notice wet gas spots on the left exhaust plus more intense gas smell on that side plus a bit more smoke. Once in a while there was a misfire on cylinder #2 (front left). So yesterday I did a carb cleaning based on 'shooting the shotgun' method and it improved. No misfires so far, but still sluggish, and not crisp reaction on throttle. When driving it, it doesn't feel as powerful as it should. V-boost kicks in as it should though. Still gas smell.
I tried a carb synchronization and when re-adjusting the idle mixture screw on #2 (front left), i realized that even if I screw in that idle mixture screw (which looks to be in good shape) all the way, it didn't seem to make a difference to the engines idle, where as on all other carbs the difference was noticeable.
So if feel like the culprit is cylinder #2 (front left), I just don't really know what might make sense to verify next. I replaced also all spark plugs and there is a spark on that cylinder. So either that spark is not regular or something makes the air/gas mixture way to rich, as i noticed the old spark plug from that cylinder looks like 'carbon fouling' (dry black deposit). Too much gas would also make sense in respect to the gas smell and the wet spots on the left exhaust I sometimes notice. There is no gas coming from the overflows though...
What are your ideas about what to checkout next?
Thanks for your input!!!
