Generally bicycle (and motorcycle) chain tension is adjusted by the position of the rear axle. On bicycles you would move the axle farther back to tighten (forward to 'loosen'). Motorcycles are a little different as there is actually (usually) a specific adjuster for the axle position (same as bicycle though - rearward to tighten/forward to loosen). Hope this helps

Yes, they are vents and part of the emission system..DO NOT remove them..!!!!

Take it back to the mechanic and explain the problem, tell him it was OK before he touched it (assuming it was, don't try and pull a fast one) ask if he has any idea what might be causing the problem. Be nice, don't go in all guns blazing or he will tell you to get lost. It could after all just be a coincidence and not down to anything he did.

Thanks for contacting FixYa. I was just reviewing some of the old unsolved problems and wanted to make sure your question gets resolved.

Chain can be correctly tightened by loosening the axle nut so the axle floats. Then tighten the chain tensioning nuts on either side evenly so they tighten the chain. When the chain is properly tensioned you will have 3/8th - 1/2" of slack between the chain and the swing arm. Then re-torque the axle nuts and lubercate the chain. Should be ready to go.

Oil pump may be on the verge of going bad. When this happens , when the engine is at idle the pressure is not enough .When it idles high is OK. There is the solution .Change either your oil pump or the oil pressure sensor-less likely .Also light on at idle may be caused by engine parts going bad as the bearings ....

hi mate adjust your cable because your slipping the clutch or if that doesnt help your ckutch plates are worn

That would be like riding a fixed wheel bike.Think about how you will stop and start. Only hydraulic fluid will leak. Bad idea!

Question edited for clarity. That sounds like it is just a bad connection somewhere or possibly a bad switch. Remove the battery leads and clean the lead contacts and battery posts with a wire brush. Smear with Vaseline and reconnect. Remove the starter leads and do the same. Then it could be the Starter Relay https://www.google.com/search?q=ktm+450+sx-f+starter+relay+location Or Starter Button https://www.google.com/search?q=ktm+450+sx-f+starter+button+replacement ..

personnaly I would replace cylinder with new OEM

All dirt bikes have a VIN. It is on the steering neck. https://www.google.com/search?q=vin+on+my+ktm+300 ..

Have you checked battery connections. Run switch in the correct position? Checked spark plug for debris? Just thinking out loud..

Drain oil. Use degreaser to clean area. Use JB Weld & allow to set up properly before adding oil.

Hi, most likely your cdi unit or ignition coil needs replacing.

took me a min or two of WTF-ing to see pic and realize you meant a 2-stroke motorcycle..

try replace spark plugs

It's a bad seal of the head gasket. You need a new head gasket and to scrape every particle of debris from the cylinder head and cylinder surfaces that mate with the head gasket. Use the factory specified gasket sealing compound and do a clean job - no blobs or pools of the stuff. The head gasket should lay flat on the surface of the top of the cylinder, and you have to make this surface free of grit, leftover sealant and any other foreign matter before you put the head in place and torque it down. Start with the head bolts just finger tight and then go by the manufacturer's specs for the pattern and amount of torque to be applied. Usually it is recommended that you get to the specified torque amount in stages, going around several times and repeating the torque pattern until you get that maximum rated amount. This will prevent the seal from shifting or warping and should make the gasket seal perfectly. This is the old school method of doing this job. and I have never seen this fail to produce good results. Take your time, be clean, and you will have the results you want.

Check the clutch, adjust, clean, or replace
