hello, i just purchased a used 98 yamaha blaster. it has a fmf fatty pipe and a power core 2 pipe on it. besides that it is stock. are their any tips of maintence wise i should know? how often do they really need work done to them? what elese....

 

First thing I would do is removed the oil injection unit and start mixing your gas. After I put on a pipe, had the cylinder ported, I think the oil injector just cant keep up with the extra airflow. I started going through rings fast. I removed the oil injection and started to use Klotz Super Technplate K-100. Smells racy go fast and works great. My motors started to last five times longer running the Klotz. Use it in my YZ125 too. Only problem the Klotz burns a little dirty and would cause the power valve to stick on the YZ. This would only happen after two to three years. Not a problem on a Blaster though. Besides that, keep the oil changed and clean in the gearbox and keep the air cleaner clean and oiled. One other problem with the Klotz is there is no rust protection. So if you were going to store your bike for a ling time you need to run normal oil through it before putting the bike away. After porting and a pipe the next best thing is a 34mm Carb.
