The old motor that was in the IT490 that Yamaha used to make back in the day can bolt rigth into the blasters frame.
Does anyone have any specs on these motors? I want to know what I will need for a carb, reeds, pipe, and other stuff.
Could you use stock blaster pipes and carb on that motor?

This link may help ya out, it all requires some frame mods...Our do some searches on it...

 

seems the pipe would be the biggest problem.

 

how so?

 

b/c the blaster pipe wont work.... you ned to find a pipe for THAT motor... and it needs to reach around the blaster and fit... piping these custom things usually needs a custom pipe builder

 

yea but the exhaust port is the exact same as the blaster and is in the same spot relitive to everything else. The pipe bolts right on, no problem, but the question is the size of the chamber inside the pipe and if it is big enough to handle that much more exhaust.

 

any one got any pics?
