I recently purchased a new primary spring From RCR, on Ricks advise I went with a white primary, actually black spring white stripe from Dalton industries. Replaced belt at same time with OEM. Before doing this my little 325 Trailboss just wouldn't or couldnt climb much of a hill. Now it simply scampers up where it once feared to go. Seems to have gained a little top end too. Now the 250 Honda Es fear me. I have the speed and the power to turn inside of them on the fire roads but I want more. At 51 years old I have not given up my need for speed but I also have to be me which means I have to things the hard way. Does any one have expirence with the 414 big bore for the 325 offered by RCR?

never even heard of it...but i would say go for it cuz rick knows what hes doing

 

We did the 414 kit on a friends 325 about two years ago. It makes a big difference in the bottom end power. Simple to do, just like doing a top end job. Never have had any problems out of it.
