400 sport won't rev up???
I have a 400 sport 2 stroke. it starts good and idles good but if you hit the throttle it spits and spuders and will backfire. The reeds look ok they had a little dirt under them and I cleaned it out and fliped the reeds over. Bike runs the same. I ran a compression test on it and got around 85 psi I removed the reeds and got 90 psi. I removed the carb and cleaned it out. I am lost on what to check for next this is my first 2 stroke. Thanks

Don't let the hp numbers fool you. Its all in how you get it to the ground. Clutching clutching clutching!

85 psi is far away to be ridden,if you got the reeds remove you might
look at the piston further front and look at the cylinder wall and
pistons ring for wear out to be there.remove the pipe will show you
even more what the shape inside is...
