4 mil question

[Aaron109]

can you keep your stock crank and get 115mm or 110mm long rod rods for the stock crank sorry if that dont make much sense

[n2otoofast4u]

110 is stock. You could put 115 on it but it would cost far more than buying a new crank with 115 on it. Regardless, putting a longer rod on or simply switching to a long rod crank will not make it a 4 mil stroke.

[Aaron109]

how would it cost more? but i wouldnt notice nearly the power difference between the actual 4mm then my stock with the 115's?

^^^^ wasting time. Haha

adding length dosen't increase stroke...  the added stroke add's CC  thats where the power increase comes from.  and then only if the cylinders are really setup for it.

okay im confused so i shouldnt buy the long rod kit for my stock crank?

really?

you probably wouldnt notice any difference at all and for the money you would be spending it would be better to just buy a 4mm longrod crank 115 rods and getting domes cut for it but if u do that you will also want to have your cylinders ported to match up your port timings also u will need to run blaster pistons which start at 66mm

 

 

OR............

 

you could do a spacer plate found here:http://www.ebay.com/itm/Boss-ATV-Racing-BANSHEE-YFZ-350-STROKER-SPACER-PLATE-ALL-YEARS-4mm-race-engine-/181240219798?pt=Motors_ATV_Parts_Accessories&hash=item2a32c24896&vxp=mtr

 

 to raise the cylinders up then there would be no porting required but you would still have to run the blaster style piston which is a 795 series wiseco piston kit found here:http://www.ebay.com/itm/Banshee-66mm-080-4mm-4-Mil-Long-Rod-795-Wiseco-Pro-Lite-Pistons-Piston-Pair-Set-/251358138820?pt=Motors_ATV_Parts_Accessories&hash=item3a861cd1c4&vxp=mtr

 

most of the guys on here will tell you u should not run the spacer plate but it is an option

 

my opinion is also not to run the spacer plate get a coolhead and have a builder cut you some domes you will like it much better being able to change your domes out to play with your compression

 

hope this helps

NO!!!!!

[Starwriter]

1 slight correction here. A 795 is not a Blaster piston. The 795 pistons start at 64.0 and are the correct piston. A Blaster piston is a 573, starts at 66.0, has the correct pin height for a 115 rod, and will work, but has a different dome angle and needs domes cut properly for it.

ok for sure just trying to get this kid rolling in the right direction lol

[WINDYCITYJOHN400]

Everyone is so deadset on a new crank and making it a 4mill......

 

Nothing wrong with a nice 370 long rod motor.

Strip your stock crank down, put on the longer rods and replace your bearings with top quality new ones. You'll never be the victim of a Wang crank.

[sheerider11]

I know of 2 people that speak highly of the 370 long rod. 1 of them is in this thread, the other built my motor. I don't have the 370 motor. But he said a well set up one will be able to be pretty damn close to my 4 mil. And a few people have seen/rode my 4 mil or know of my builder.

[Surfrjag]

So for about the same price someone can be close to your 4mil?

Why not just go to a 4mil or better yet just stay with a 350 stock rod "well built" and still be close.

[WINDYCITYJOHN400]

LOL.......In that case, why not just keep your motor the same till it's so wore out that a tow strap is needed to start it?
