I am about to get an 86 triz and my friend has a 2001 400ex I was just wondering would a piped and bored .10 over tri-z beat the 400ex?

 

seein how the tri-z is a 2 stroke, and seeing how a 3 wheeler has a pretty nice amount less weight, I'd say it would be pretty even but adding the pipe and bore jobI'd say it would have a slight advantage over the 400.

I'm just assuming that the tri-z is one of the 250 models..

 

id say the tri-z would smoke it

 

If the TRI-Z is in good mechanical working order, it should easily run away from the underpowered 400ex.

 

I used to have a TRI-Z and I just rode a 400EX the other day.The Z will smoke it bad, it weighs alot less and makes alot more HP, you tell me.

 

Hi motoxer, i think that tri-z you are looking at will beat my 400EX. Talk to ya later

 

If the yamaha's engine is still strong, it should embarrass the 400EX bad. The only chance the 400 has is off the line, where the Z will want to wheelie. Top end should be no contest. Karl
