Put a new battery in her and changed the oil and a spark plug, and she fired right up! These bikes are beasts :) It does sound a little choppy, and seems underpowered, but she does have 50k miles on her. Do you think the 6 month old gas is making it choppy? I'm driving it around to get the...

Thanks for the support guys. I would do the work myself, but I live in an apartment, and the manager does not let me work on my bike in the parking lot. I still do little things myself, but I can't really tear into the bike, or believe me, I would do all my own work. I'm waiting for...

Ok, update to this fiasco: I talked to the general manager and he is going over there to look at the bike tomorrow (hes from another sister store in Raleigh) . I got a call from the parts manager, who was quite belligerent, telling me I don't seem to understand the situation. When they...

Earlier I had problems you guys identified as a failed starter clutch, correctly. I managed to get my bike started and took it up to the Yamaha dealership in Raleigh and they didn't call me back to tell me my bike was finished which made me a bit concerned. When I called today, they told...

Battery is fully charged on both (already thought of that), but thanks for the reply. It is probably the starter clutch like you guys said. We had our first cold snap the morning this started happening, and it actually starts better when it is warmed up. Unfortunately I can't work on my...

I have a 2003 and 2006 Vmax and have the same problem with both. I have a problem where the starter does not seem to be engaging the flywheel. I replaced the starter thinking the gear might be worn down, but the same problem exists, where it makes a rattling sounds and occassionally catches...

It came with a set of Supertraps and the carb was stock. That was their rational for suggesting a jet kit, and I agreed with them. I do have a carb sync guage, I will try that next. I'm wondering if doing the shotgun method of cleaning might help too. Whatever it is, I'll have to do it in...

It was stock but when the carb was cleaned at the shop they convinced me to put in a stage 1 kit. It didn't fix anything and it runs the same as it did before the kit was installed

Hi folks, I rescued a 2003 VMX12 from a guy's barn a last year with 6k miles on it, and have fixed all it's problems but the following: When I first start it and lean back on the throttle, it bogs, and I have to rev it up to get it out of this funk to be able to go forward. If not it...

I traded my 86 max for a 2003 with 8k miles on it. It ran strong til I came to a stop at my house where it stumbled and stalled. I decided to look at the carbs and saw this thing poking out when I pulled the needle out. How do I get this jet in? It doesn't seem to want to screw in....

Replaced fuel filter, and since it seems to be running rich, I'd say fuel pressure is ok. Fuel pump clicks when ignition is turned, but haven't checked pressure. Replaced spark plugs with correct irridium plugs and new wires, but did not change anything. Checked all fuses (for vboost) and...

It synced fine. I'm not a fan of the liquid sync after doing it, however, since the fluid chambers have any leaks around the set screw, it will suck all the fluids into the cylinders. It has to be closed, but not TOO tight... blah. I'd rather have vacuum gauges.... But, with that said, it...

Hey Vmax Pros, I bought this 86 vmax a few months ago and have been working the kinks out of it ever since. When I got it, it had horrible gas mileage--like 18 mi/gallon. I did a shotgun carb clean and brought it up to 32 mpg at one point, but it was misfiring a bit, so I did a vaccum...

Hi, I'm relatively new on this site. I currently own 2 vmaxes, a 2006 and a 1986. In total, I've owned 3, but the 1997 vmax (my first one) was totaled when some dude decided to cut right across an intersection from the left hand turn lane, and I laid it down to keep from t-boning him. I slid...

I recently rescued a 1986 Vmax from some young air force fellow who was moving overseas and more or less dumped it due to "engine problems." The "engine problems" were dirty carbs that were fixed using the shotgun approach listed in these forums (thank you very much), but I think the Vboost...
