i just bught a lrd pipe and silencer for my blaster and need to know what jets i should start out with

 

you should call LRD and they should be able to tell you.

 

are lrd pipes an dsilencers any good ipaid 120 for my pipe and silencer

 

What all has been done to the Blaster?
Do you have an aftermarket air filter?
Are you running with the lid on, or off?

Our 93 Blaster is running an FMF "Fatty" pipe, and a K&N airfilter with the lid off. I installed a 300 main jet, and it runs great!

If no mods to the airbox and filter, try going to a 250-260 main.
Be sure to do a proper plug check as this is the ONLY way to tell if you are jetted correctly!

 

its all stock now so your saying try a 250 or 260 main and try sizes around there but are lrd exhausts any good

 

I have no experience with LRD pipes made for Blasters.
I had one on my 250R, and it worked well. I would imagine LRD makes a good Blaster pipe too, but like I said, I have not tried one for the Blaster, nor have I heard of anyone using an LRD pipe on a Blaster.
