stroker

[racer]

Just thinking? I know dont do that.

 

If you put a long rod crank in and a spacer. What are you really doing?

I thought you got better performance by reduceing crank case area. now its getting bigger. And your not moving anything up top. If you run reg pistons there produceing the same compression just higher up.

 

Now what makes sense is no plate and a milled head for piston clearence.

 

Someone help me understand this plate moving cylinder up and longer rod at the same time and actually makeing your bike faster.

 

Thanks

the plate or cutting head is not for the longer rod, it is for the added stroke length. pistons with a higher wrist pin location are used for the longer rod a plate or cut head is used for the longer stroke

well, actually a plate can be used with a LR setup when you use stock style pistons. the plate is 5mm thick to nullify the effect of the rod length. i run one because i couldnt find the pistons i wanted in the size i needed for a long rod crank.

but does this mean that if i want to get a 4mm stroker i can keep the pistons i got if i get one with a spacer plate. i don't want a long rod thou, just stroker. and i don't want to ruin my motor, so i need to find out

if youre going to get a stroker your probably going to port it. to adjust the durations and timing and just so you dont waste some of that power. so if youre gonna have it ported why not just do it when you have it all apart. however when you port it you need bore it as well, this clean up rough edges and nasty little things that can tear that motor to pieces. and since youre gonna get new pistons anyways with the bore job you can just order long rod pistons. so if you really think about, it'd be a mistake not to get a longrod crank.

 

that all make sense?

i get what you are saying, it makes sense, but the thing is, i don't need new pistons and bored out because the ones i have aren't that oldso really all i need is a stroker cuz i don't wanna buy new pistons. not to say it wouldn't be worth it but, sadly, s#*! costs money , plus i think it will have plenty of power with just that., but no one answered my ? on a diff post. will a stroker hurt bottom end a lot too, cuz it ain't great at all to start with. i guess i just want to know what kinda power to expect. Thanks...

yah don't get the part where they said if you stroke it yah got to port it. seeing that you ported it yah got to bore it because of spers off the ports.Now that you bored it you need new pistions.... . The reason for the LR is more power less friction and last longer..... Plus it's hard to find a non-Long rod stroker crank. I would call and contact a builder personaly and see what he says about it all. Im mean whats 1.2bones to have jim do it?

Not that a stroker crank automatically gives you tons of torque, but if set up and ported for it, it will give you tons of everything including bottom end...you CAN have your cake and it it too....Jim
