I have being enjoying the rides on my bike alot but recently im facing some issues with it .. when she gets warm , she doesn’t start .. but as she get colder there is no such issues . Can someone please help me figure it out ? My timing is slightly off but it cant be the issues since there is no any problem when starting the engine when cold..
Hi thank you my67xr.. Recently i checked the valve clearance, except for 3 valves which are slightly out of spec , the others are in range ..but i haven’t cleaned any valves since i got the bike , can that be an issue? AND ALSO my exhaust gaskets are worn out , can a leak on the exhaust cause this problem too??
Sounds like it is rich and that can be because of low compression or the pilot screws are backed out too far.
Have you checked that the fuel tap and fuel filter's are not blocked? There should be 2x small filter's inside the fuel tank, and possibly another before the fuel pump or carburetor's Could also be a blocked fuel tank vent in the petrol cap ? When the bike is hard to start when warm, have you tried opening the petrol cap to see if there is a vacuum ? eg blocked vent And as Maelstrom mentioned it could be too rich, do you need to use the choke when starting the engine cold ? Would most likely be making the spark plug electrode's and insulator's black and sooty if it was You should be able to find new exhaust gasket pretty easy, sometime's another motorcycle will use something similar
Hi thank you maelstrom .. even i thought the same so i turn the pilot screws from 2.75 to 1.75 (on all four) but still the same issue
My petrol tap is working fine cuz i cleaned the carburetors recently and also at that time i cleaned my tank as well as the petrol tap .. YES , i have to use the choke when starting up the bike ..nevertheless its cold or warm i till have to use the choke before she get started .. thanks you so much for these reply’s my67xr .. plus for the info regarding exhaust gaskets
I will.. thank you maelstrom .. Bydaway can in anyway spark plugs malfunction when the engine get heated ?? My spark plugs have done quite a milage but when i test them using a multimeter they read fine , and the gapping are on specs as well but im kindda doubtful whether they malfunction when the engine is warm .. cuz when i try to bump start it sometimes the bikes start but also sometimes i hear no sound of any firing on the engine .. can that be a cause ??
