Will I notice a difference if I run VP U4.2 ? I read it's a leaded fuel, does this have any negative side effects?

I think it may harm your O2 sensor after a while.I ran some in my kfx.It works really good.I am now running Motorsport 103 from VP.Its unleaded.

You will notice a difference if you remap it...it needs more fuel.

i dont think we have an 02 sensor?

nope we dont have an 02 sensor that is why you have to buy a programmer to change the fuel curves after any modifications.

I know when I used it in my yfz you had to drain the bowl after each ride. that stuff tears up some seals.

where do you guys buy your VP fuel from?

 

[mxrider38]

I buy it from a local dealer. There are quite a few people around here that sell it. Just go to your local mx track usually here there are local vendors at the track that sell it.
