Any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate. 20w-50 for warm climate/touring. Do not use any oil that says Energy Conserving on the label . It will shorten the life of your wet clutch and transmission gears. Synthetic oils will help your bike run cooler and shift easier.

bring relay to dealer and testit--make sure connections are tite-may want to consider starter button

voltage regulator not working

Beside the fuse box

If you have vacuum carburetors , you need to have an air box that creates vacuum for them to work. By eliminating the air box and putting on pod filters you have made mixture super lean and screwed up the rate performance curve of the carbs. You may be able to get it to run by re jetting the carbs bigger. The vacuum tops still may not as well as they can. Remember your little high performance 250 is designed to 100MPH stock. You may want to think about going back to the stock air box, just about anything you do will only lesson the performance on this model.

Please provide a photo.

The light gets brighter because the higher crank speed is generating more electricity. Your battery is getting weak. Check to see that water covers the top of the plates in each battery cell. A strong battery will make up the difference at idle speeds. Most bike batteries will only last two years or so. Please rate my answer. Thanks.

Take off the side panels, I believe 2 screws each, then pop off the "buttons" that hold them in. On each side, there's a screw for the seat. Remove them, slide the seat back, and you have access to the battery.

Sounds like fuel to me! Check fuel pressure and fuel filter.

If It was my bike I would first replace the side stand switch and the clutch lever switch. I would do one at a time they work together to complete the starter system they tell the bike thats it's ok to start. ck the wires going to the switches and connectors for a rubbed spot or burnt spot on the wire.

Your spark plugs may need replacement or a weak coil.........Hope this helps.

its electrical check security of the entire spark plug circuitry starting by taking the plug wires off and remove the plugs to check to see that ceramics aren't cracked , if plugs are good now inspect the inside of the plug wires for corrosion, if good now check the other end at the coils for integrity. since the bike does run good up to 9000, then i would say that your plugs are probably good, and the spark plug wires are probably good also so i would look into the spark unit assembly next for loose connections ..a lot of things could be causing this; a bad tilt switch, a bad rev limiter, a shorted wire to the pulse generator system..this is not a simple fix..good luck.

Your looking at around £400 to £600 or bit cheaper if you call bike breakers. You may pick up the parts at a snip of the price. The throttle however may be a damaged cable and if you replace the throttle cable it shouldn't cost no more than £50.

FL indicates a Fuel Injection problem. This could be anything from a dirty air filter to a plugged injector or a fuel mapping problem. Take the bike to a dealer and have them read the error codes to see what is going on.

Replace brake light switch or adjust.

You can try drilling the lock out. You will need to know where to drill though because drilling in the wrong spot can make it harder to open. Best thing would be to just take it to a locksmith

could be the starter.

Check float height in carbs.Thanks for asking and I hope this helps out.Please leave me 4 thumbs up.

This could be due to timing screw being incorrectly set
Locate gold timing screw on the carbrettta turn it clockwise only slightly till bike idles without choke on, Then when choke it on it should idle a touch higher.
