No power under 7 grand on my rgv

Hi, Floyd and the usual suspects are:
1. Idle circuit and transfer ports clogged.
2. Air fuel mixture adjustment too lean.
3. Pilot jet clogged.
4. Faulty accelerator pump.
5. Float level too low.
6. Float bowl contaminated old fuel, water, dirt, rust, etc.
7. Float bowl vent or overflow tube clogged.
8. Fuel flow to carburetor restricted.
9. Intake manifold leak.

find a running sr 250 and swop his cdi unit with yours if the bike runs, fine. if not put his cdi back in and try again. if the good bike now starts it will indicate that your cdi is faulty. the cdi is located under the tank inside the frame. don't buy a second hand cdi unless you can test it on a working bike. they are very expensive and you don't want to buy a dud

Sounds like you have a carberator issue at this point. Bike is not getting enough fuel. Good luck and have a great day. HDTV GURU JAY

hi,you might find that the bike is top speed limited,the way that the manufacturer achieves that is to limit the rpm in the top two gears hence only reaching a given top speed,the only way to fix that is to generally replace the cdi unit with an unrestricted version,or in some cases the manufacturer or alternatively accessory shops can supply the derestrictor..hope this helps,,cheers

spark plug wires probably aren't seated firmly or cdi unit is going bad!

Could be a crack in the boot between the carb and the head. this cracks usually from back firing. also check the exhaust flange to ensure that it is tight. Have you checked the valve clearances lately.

check your gear ratio ie chain and sprokets if thay are to high of a ratio this will happen . as these bikes dont start to make power untill thay rev up hight . thay are tuned for top end revs and speed

your cdi unit is suffering a from power surge try to check the output power if it is stable.

sounds like you need to refit carburator w/ a larger main jet to richen that cicuit at approx.7/8 to wide open throttle. this is very often necessary when switching from stock to aftermarket hi- flow exhaust system.

check ur valves and the gaps, try checking ur spark pug gaps
