I am looking on getting a 440 kit for my ltz. I want to know what is the best kit and what is the cheapest. Is reliablity less than before or are any parts breaking from it. Please give me anything that could help.

 

give Lazarus Sommers a call at GT Thunder.

I would go with the 470 kit [img]i/expressions/face-icon-small-wink.gif[/img]

 

go with the 453 kit from CT racing. it will fling u off the back .

 

On CT's dyno my 463 made almost 50hp acording to the new ATV Rider mag.

 

well give them a call about there 440 kit it actually puts out more power then the 453 kit and its still class legal. Its alos 100 bucks more I think is the difference in price and I tell you what it beats the other 450 from the blue/white ones to the red ones. Trust me I know the 440 flies I have one.

 

I wouldn't reccomend the cast iorn sleeve kits. they seem to be less reliable and shorter lived than others. Athena just came out with a bolt on plated jug 435 kit. It doesn't use a sleeve, thus eliminating those problems.

 

WOW! that is impressive.

 

tell you what you can bore the bore to 440 and then renikisil the cylender and then you dont have to use a sleve. That is the way it should be done.

 

is boring it out then relining the cylinder cheeper
