Question about 2002 Yamaha YZ 426 F
Thankz to the fixya team,
between my dad and i, we managed to solve the problem. Regards to the starting, well all we did was change the plug, the original plug had a faint spark, after fitting the new one, two tries and she started. With regards to the exhaust, well the hot start knob has a valve and this valve has a little spring that operates it. Well this little spring was really knackered and after replacing it with a substitute spring, ive not had any problems since. We reckoned it was getting to much air into the combustion chamber, therefore igniting petrol in the exhaust, (hence the glowing red hot pipe) since we changed that spring, this hasnt happened, we reckon thats the solution to this problem.
