losing power

medicaldawg · 05-17-2011, 08:49 AM

K so ive got a 99 1500. In 5th gear when i get it up to around 55 and ease off the throttle just a bit to maintain 55 its like my bikes loses power but then the power comes right back. Its not cutting out or jerking real hard. I can just feel it. Its as if you were pressing the brake and then releasing them. It also does it in 4th around 45.

You shouldn't be in 5th below 60-65.

It sounds like you're just bogging down a little.

Try running a few rpm's higher.

i agree but unfortunately this is something new. It doesnt run rough though

**ringadingh** · 05-17-2011, 12:06 PM

Could it be a tank of bad gas, or a bad plug.

medicaldawg · 05-17-2011, 12:48 PM

yup gonna get some gas treatment and test the plugs

Mine does the same in 5th at that speed. I can't run it below 60ish. It is so slight a power issue that a bit of bad gas or plug could make it seem like a major problem. It wouldn't hurt to run some Sea Foam through it.

redjay · 05-17-2011, 04:08 PM

Do the 99's have a fuel filter ? Could it be that ?

mikeyger · 05-17-2011, 04:59 PM

under the gas tank!

AlabamaNomadRider · 05-17-2011, 05:12 PM

Clogged fuel filter would cause a loss of power. Could be the gas if it hasn't been doing it before.

medicaldawg · 05-17-2011, 08:01 PM

so can I clean the filter or do i need to replace it?

macmac · 05-17-2011, 08:34 PM

No hot brake rotors are there? And it is a bit low to be in 5th. Both 4th and 5th are over drives.

mikeyger · 05-17-2011, 09:10 PM

I use a purolater fiter from autozone Just take you'res with you and get the same size that will fit the hoses I think it is 5/16 for 3 or 4 dollars You can also see trough them since they are clear

medicaldawg · 05-18-2011, 08:12 AM

havent checked to see if the rotars are hot. But i did just change the brakes and they had plenty of pad left was just getting ready for the rally. Will pick up a filter today and replace.

medicaldawg · 06-08-2011, 07:44 AM

replaced filter. still doing it. Currently running sea foam through it so we shall see if this solves the problem.

mikeyger · 06-08-2011, 09:13 PM

Since you're new mods I would go ahead and put 4 new plugs (12 Dollars). It can't hurt and you could get a better reading on how you're new air intake and carb modification is doing!
