I have a montesa 315r with a slight bend in the header pipe and it doesn't quite seal on one side when bolted on what sealant can i use on the joint where the exhaust connects to the cylinder?

 

Thanks in advance

Select a socket that is an almost exact fit in the mouth of the front pipe, use and extension bar and clamp bar in vice, gently force pipe to take out bend. DO THIS CAREFULLY and you may find you don’t need sealer. If hear can be applied to bend area this will help. Sealant on the front pipe is not s good idea as any leaks will cause the temperature around exhaust port to rise and probably cause seizure of piston/rings. If you must use a ( considered a bodge) sealant get a high temperature spec from an automotive parts supplier, Europarts, Halfords....there are many about.
