How much difference is there between the Sparks and Trinity pistons? Both are made by JE I think. The Sparks is 10.75/1 and the Trinity is 11/1. Also what about valve springs, is there any differnce in them. One set is $60 higher than the others. How about Speedwerx's Ti valve springs? Ok one more I can't find any info on HOT CAMS. I was told to look at atv addicton but can't find anything there. Am I just missing them or looking in the wrong place?

 

I can't say about the other stuff but get the best valve springs you can. Those suckers work hard & the Ti springs are susposed to last a lot longer than steel.

 

Do you know or have an opion on who makes the best springs?

 

Sorry I haven't started looking for quads yet.
Manley makes good springs but I don't know if they have any for quads.
