20 Most Recent Yamaha 2004 Blaster Base Questions & Answers

OMG = there is a youtube video on it. can you believe that?

Name of manufacturer

Use heavy duty SAE 80W-90 gear oilEngine oil does work but the oil will not last as long nor will it protect the bearing's/gear's as well as gear oil. Thick dif oil can work to.Also the gear box is should be sealed.

YEP// the question is WHY did you swap all this??

Sounds like an air leak... either at the base gasket or the reed valve gasket. or the carb/reed intake boot...MAYBE THE HEAD GASKET... ...AND ... get a qualified pro to look at your carb..tell him which parts you replaced...

sounds like a bad coil if there's no reading on it

Sounds like you need a rebuild. Dont use cheap china parts, go online to http://www.amazon.com/Wiseco-PK1089-2-Stroke-Piston-Top-End/dp/B0050FYN4Y/ref=sr_1_sc_2?ie=UTF8&qid=1420937950&sr=8-2-spell&keywords=yamaha+blaster+wise+co And get this. This should be everything you need to rebuild it. Now you need to MIX your oil. Not use the tank. Google blaster oil tank bypass and just remove the tank as it can tear up the engine badly. The oil pump can send shards of plastic into the crank and cause it to fail. Once you have done this, You can have the engine built, mix the oil 32:1 and insert into the gas tank. After this is all complete it should all be running even smoother then before. For any other help go to www.Blasterforum.com

I would check the plastic heat isolator between the carb and cylinder head for leak.

a lot of people that take these apart put them back together backwards. make sure it is right. most of those carbs are not adjustable other than the jet itself. make sure your fuel tank is clean and fuel lines are clear/ fuel filters are clear or new.
