Sounds like you need a new power valve in the cylinder. They can go bad and thats how they will act. You have to take the cylinder off to change it. If your that far you might as well put a new piston and ring in it.

When I start my 1990 Talon TSI runs fine as it warms up runs real rich has no power and boost is very high. At low RPM around 2500 its fine after that all hell brakes lose bogs down and wont go ?


check the air cleaner and replace if necessary. ( low air volume = rich mixture ). Check/clean exhaust system as back pressure may be too high at high rpm's. Check fuel quality and do not use e-mix fuels.

Powerband


The power band is the point wheneverything is nominal and and peak performance is realized. The air/ fuel ratio , timing, rpms It's mor predominant and noticeable in a motorcycle because of handling and weight All engines have them and these "power bands are really the peak of what s also called the torque curve Band meaning sp[ecific point and duration everything is working together. a gas lawn mower engine is set up to run inside this band. Thats why it doesn't fall on its fsce on the first patch of grass.
A diesel engine has a specific rpm range it has to maintain under load to get nominal horses.. If everything is functioning at nominal, max power is put out. Surprisingly enough it can be felt in all engines if paid attention . That's all it is, no special "bands" or parts. Knowing where the power band(range is makes a big difference on any machine. On an electric motor peak torque is @ let's say 1850 rpms. go faster useless lower toyque. go slower power drops To keep the range of the power band constant. everythinhg needs to be constant, like fuel mix, spark plug condition ,air filter andcarb adjustments.. I had a bike I hate and feared the power band. I would fall into it not paying attenyion and it would litterally crawl out from under me. All it is is that narrow band of peak performance..

You have found the HI and LOW settings. The idle wouls be set by starting and warming the unit up. After warm up, take your screwdriver and turn the LOW screw OUT until the engine starts to lose RPM's. Turn the screw IN until it starts to lose RPM's. Once you have those two points, back the screw about halfway between. You can do the same for the HI setting if you need to. Good luck...Lee

If the choke has an adjustment point, then adjust the choke to a good overall working powerband. If it still doesn't act correctly, look for vacuum leaks. If it is an option, you may want to install a manually operated choke lever.
