Goldwing 1500 Trike (1997)

[BK61]

When I ride my trike on the highway at 65-70mph it rides fine but after about 25 minutes it goes down to about 50-55 mph. If I stop on side the road then start back again it will go back to 70mph for a few minutes then back to 50mph again. I thought it could be bag gas so I put new gas in but it does the same thing. It is almost like when it is getting near 25-30 minutes it will start do it. It will get me home at 50-60 mph but that is it. I am trying to see if this could be an engine problem or still something with the gas.

Bryan.....Welcome to Trike-Talk.........Make sure your gas tank is venting properly ,

What you are describing is classic signs of a air bound gas tank...

Bryan, Welcome to Trike Talk. I agree that it sounds like your fuel is being restricted due to your tank not breathing. Good luck..... Jim

Hi Bryan, to Trike Talk

Sounds like a fuel delivery problem

As already mentioned, have a look at your fuel cap first, have you had any work done to your trike recently?

Try running some SeaFoam in your gas also, it could be also a build up of varnish in the carbs from the crappy gas we are forced to use

While on the side of the road I did take the cap off and tried to run it but after 2-3 minutes it when back to 50-60mph.

Hello & to Trike Talk.

Have you checked the hose that leads from the gas cap to the open air for an obstruction or pinch?

The only thing I did was take the gas cap off and see if it would work but it did the same thing.

Did you drive with the cap off?.. I had a 73 Pinto that did the same thing… Caveman style I just drilled a hole through the gas cap. And vented it . Didn’t have a problem after that.

Yes I took the cap off and ran about 3 minutes and it started doing the same thing as before. Falling down from 70mph to 50mph.

This could be sticky floats in the carbs, hanging up from varnish build up and not filling the bowl completely

Could also be bad gas, it happens
