Running like crap
My spree hesitates then bogs down. Please help, I have tried everything with the same results. I tune the carb and take off for a ride, after a block or so it just looses all power and starts to sputter.
What I’ve done:
Compression 116-120
New Chinese carb
I’ve tried 3-4 rebuilt factory carbs
New air cleaner
New spark plug
Tried cutting off exhaust which actually worked but super loud
Put new used muffler which I can blow through/suck easy
New Chinese CDI and coil
New premium gas
New oil
New fuel check valve/filter
Problem remains. I have now put everything back to stock, rebuilt carb, CDI, coil, air tube/box/filter, new spark plug. I have 3 sprees and they all seem to have the same issue. Any help would be much appreciated!!!

Re: Running like crap
You mention everything except the ONE thing that is PROBABLY giving you trouble.......petcock.
Certainly sounds like a fuel-delivery problem.
Not sure what you are calling "check valve"
You also say "Cutting off exhaust"....don't do that.

Re: Running like crap
So I’m referring to the check valve in the fuel tank. It has a filter on it. There are 2 lines that come out of it. One is fuel one is vacuum which allows fuel to flow when the engine is running. When I disconnect the 2 lines at the carb and apply vacuum to the one line fuel flows freely. There are no other parts to the fuel system. I have replaced the part anyways with a oem Honda valve/filter. I am getting a good fuel supply to the carb. I’ve even used a plastic bottle with a line direct to the carb, same issue.

Re: Running like crap
Is the air filter secured tightly? I've ridden around, had it come loose, and caused it to run poorly. Might need to zip tie it down

Re: Running like crap
Yes it’s a new filter in a good solid box. The tube to the carb is as it should be. But it doesn’t matter, if I take all that stuff off it will run great at first then just losses power sputters for a while and dies.

Re: Running like crap
I went through a whole list of things I’ve done at the start of this thread, none of these things had any effect on the problem
Re: Running like crap
Maybe the gas cap vent is plugged
