stoker crank I think?

[dsimo]

So here the deal I traded my 91 xr250r for a 99 banshee this banshee came with a box of parts! In this box of parts was a brand new crank! The banshee needed a top end rebuild when I ripped it apart I found it also needed a crank rebuild so I put the brand new crank in it and found that the piston pops out of the jug so it must be a stroker right? So the problem is how much of a stroker is it? And also I already have some new piston just plain old 65-mm pistons. So if it is a stroker can I get by with just a spacer plate or do I need different pistons or both. Also I think it's a hot rods crank simply because it has those rubber O-rings on the mid bearings instead of those little taps hanging off the bearings. And lastly I was hoping to keep this thing stock (lack of money) so if it is a stroker can I keep the stock pipes and carbs????

My son's shee has a 4mm long rod and stock pipes. It runs good. Pipes are the best bang for your buck tho. Do a search. His has a 2mm head gasket. Or you can go 2mm jug spacer or have head rechambered for stroker domes. Also has stock carbs.

if your broke and you just wanna get it running, you can get a spacer plate and let it go. if its a long rod setup, your gonna need 795 series pistons though.

Is there a reason you cant use a spacer for a long rod? I see they sell long rod spacers and stroker spacers? I guess my question is stoker or long rod if you but a spacer in between the jugs and all the ports line up the piston is not hitting the head or crank it should work right?

If it is a hotrods crank it should say hot rods on the crank. Hotrods makes a 58 (4mm) with a 110mm rod or a 115mm rod if you have a 58mm stroke with a 110mm rod you will need a spacer or cut domes and 513 series pistons. If you have a 58mm stroke and 115mm rods you will need a spacer or cut domes and 795 series pistons. Either way the bike will not run as good as it should without doing the porting necessary to get the port timings correct.

if you are real tight, and wanna make power, i can do a deal with you. i have my stock crank, running real strong, no vibrations, noise, or any other issues that i know of. I also have some fmf god series pipes paired with toomy stingers, that rip your arms of in the mid-top range, that i will send with some jets, and possibly something else you need. trade strait for the 4 mill if it is so. I'm not trying to rip anyone off, so someone step up if it seems like a bad deal. if your interested, try to carefully clamp the crank bearing, or set it in the case, and measure the stroke, and let me know

 

I'm planning on starting a 4 mill build soon, and probably pv cyls
