85 TRI Z powervalve??
Heres the scoop. I am getting a powervalved top end from an 86 or 87 YZ that has just came from the machine shop port-polish and a bore job. I am debating on puting it on my 85 Z. If i do should I use the Tri z bottem end or go with the yz bottem end. What is the power valve going to do for me. how much difference will it make. I am running a DG pipe and a Kehlin 38mm carb.... i got a tip on a kehlin 41 1/2mm carb which is going to give me the best perfromance. is 38 enough???.... will the bigger carb make bring it to life. Im going for flat out wicked fast with this one. I have an 85 1/2 i can trail ride with. I hope someone out there has some insight for me. I dont see to many powervalve conversions. If i should extend the swinger.... how far should I go?? pleas someone help before i spend money on nothing.
