Yamaha 2004 Blaster Base - Answered Questions & Fixed issues

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.

Check head light switch

Hey Anon, this is NOT something to "try and learn" how to do..find a professional that is will to tutor you when you do this for the first time! It COULD save you A LOT of $$$$!!!!!

If you have good spark then it's most likely a fuel issue, anything off of idle is dealing with the main jet and metering needle, clean jet and check needle for excessive wear.

Check the fuel flow through the tank valve. There are screens inside the tank that may be blocked and restricting flow.

must hold brake, use the foot brake!

It is inappropriate to explain how to possibly steal a machine on this public site.

Assembling a recoil system on a Polaris 400 Xplorer involves several steps. While I can't provide an actual diagram here, I can outline the general steps involved in assembling a recoil system:

1. Preparation: Ensure you have all the necessary parts for the recoil assembly including the recoil starter, recoil housing, recoil spring, and any other associated parts.
2. Mounting the Recoil Housing: Begin by mounting the recoil housing onto the engine. It typically bolts onto the engine casing.
3. Inserting the Recoil Starter: Place the recoil starter mechanism into the recoil housing. It usually fits into grooves or mounts within the housing.
4. Attaching the Recoil Spring: Connect one end of the recoil spring to the recoil starter mechanism and the other end to a fixed point within the recoil housing. This provides the tension necessary for the recoil starter to function properly.
5. Installing the Pull Cord: Thread the pull cord through the hole in the recoil starter mechanism and tie a knot at the end to secure it. Wind the pull cord around the recoil starter as per the manufacturer's instructions.
6. Testing: Before completely sealing the recoil housing, give the recoil starter a few pulls to ensure it functions smoothly and retracts properly.
7. Final Assembly: Once you're satisfied with the recoil assembly, bolt down any remaining covers or components to secure the recoil system in place.

Always consult the specific service manual for your Polaris 400 Xplorer for detailed instructions and diagrams tailored to your exact model. Additionally, if you're unsure about any step, it's best to seek assistance from a professional mechanic or someone experienced with small engine repair.
