Hello guys. This is my first thread here. I have an 88 hurricane 600 that I put a new engine into last week. I got the bike running, but had a nasty rock knock. I pulled that engine out and put in a donor engine. It runs and starts great.

The problem that I have is that it dies after about 10 minutes of riding. It has done this to me two days in a row. I just got it titled last week so I have not put many miles on it yet.

I took it for a ride yesterday and it started up and ran great. It shifted great and had good power. I was riding through the country roads with a speed of 45-55 mph. It ran good for about 10 miles then it starts to hesitate, and surge a little bit. Then when I came to a stop the bike stalled and would not start.

I had to engage the choke and it would start again, but it ran horribly. It was bogging, and made absolutely no power. I was able to ride back home but it was tricky. I had to slip the clutch and give it like 5k rpms just get going from a light. Once you are moving it will only go about 35 in 2nd gear, even if you have the throttle pegged. Even if you pull in the clutch it wont do anything.

Do you guys have any idea where I should start? Like I said it runs great and makes awesome power until this happens.

thanks for the help


EDIT- it has all fresh gas in it, and the tank vent is working. When it staled, I opened the tank and it didnt change anything.

 

Does your fuel pump work?
Fuel pump relay?
Sounds to me like something is getting hot and then stops working.
Ride around your neighborhood and see if it dies again, then open one of the carb drains and see if there is any gas in there.

 

very similar situation happened to me. it was just one of my floats getting stuck and over flowing. and mine also needed a lot of throttle to get going. i world say clean the float assembly very well.

 

try riding with the gas tank cap off it might be the holes in that not letting air in to replace the fuel you have used . simple things first then look at your carbs
