I recently purchased an 89 yz 250 which is rather difficult to start cold. I have to place a small amount of fuel into the combustion chamber to get it to fire. After it starts once it will fire up every kick. Any Ideas???
choke assembly not working right<when you get it running and warmed up will it make the bike run rich and blubberry>
