    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Jets, Pods, and Gas mileage

Riding style will make a big difference on gas milage. My 1150 around the outskirts of town taking it easy and putting along mostly in the 40 to 50 mph range gets 45-47 mpg. On the highway cruising at 65-70, milage is 40-41.
At 80-85 mph, milage is 35-36. At 100-110 mph milage is 28-30.

So I'm wondering if riding style really does have a huge effect on mpg of a carbed bike. I've not yet tried riding like a wuss for a whole tank yet, but maybe I will.

After ripping the carbs apart and blasting the crap out of them, my bike still gets horrific gas mileage. I'm talking less than 25mpg on every tank.

As stated riding style has a big impact on mileage and it sounds like you do hammer it pretty good. But still 25 mpg is low. Certainly try short shifting for one whole tank just for a reference point. But I would bet you have some ther issues going on there. Check your plugs. Check to make sure your brakes aren't dragging.

Andrew, why do you hate your pods?

...Its 38 deg. F here right now :(

Well, IMHO they are awesome for performance, great for improving airflow, but total crap if the bike is used in the wet.

Personal experience, and dyno testing shows that these "pod" air filters, (even when oiled correctly) mean running rich during damp conditions, meaning that you are effectively riding with the choke pulled on.

What happens is that the moisture covers the air filter surface on the directly exposed pod, and restricts air flow to the carby, meaning that it sucks more fuel and less air and also has to suck a lot harder to get the air fuel mixture into the engine.

As we all know, Running any engine with the choke on increases fuel consumption and decreases engine performance.

Another side effect is that the increased air fuel mixture washes some of the oil from the bore and increases wear in the engine.

again, this is my findings from personal experience and dyno tests.

While what you state here is true, the effect will differ dramatically depending on bike design. Some bikes have the pods in a fully open environment, while on my bike, and my 700 before that, the pods are almost entirely blocked from moisture contact by the side covers. Personally I've never had any problems riding in the rain with pods, but have heard of some people having water from the tank pour directly on their pods, obviously effecting performance.
