Hi,
I'm Jelle and I live in the small country Belgium ( in Europe )
Just 21 years old and I love racing my banshee.
My banshee only has Goldspeed exhausts , so after 2 years of riding it, I'm searching for some real hp gain !!
I don't want to modifie my case.
So I'm searching for the best cylinder kit without case boring.
I'm thinking of 421cc + 35 pwk carbs + 4mm cranck ?
I don't know what are the good brands of aftermarket cylinders and cranckshafts , so that's why I searching for some professional advice from you guys !!
The setup is just for having some fun on the streets , It's legal to ride here in Belgium on the streets ( I have my driver license )
Some times I also go on the track, mx but just for fun.
Looking for +- 80 - 90 real HP
(And sorry for my bad English) ...
Thanks in advance !!!
