Thats why I spent the extra $$$$ on OEM, My old OEM crank lasted 22 years:D

I put several of the Wiseco cranks in peoples 250R's with no problems at all. The aftermarket ones don't pressure test very well because the end of the crank is machined a little looser. I think the material they use may expand a little more becuase they never had any symptoms of an air leak while running. The OEM ones are the best.

Yup, I'll be going back to a stock crank!

[riderssb250x]

can't buy the oem cranks anynore! should I get a hotrod conecting rod rebuild and just revuild my oem crank?

or where can I buy a new oem crank what do you guys usually do in this situation rebuild your stock cranks?

[86 Quad R]

i have each en every one of mine rebuilt using pro-X rods. i am currently 4 years on my last build. last i checked its still to spec.

[riderssb250x]

where can I get the prox conecting rod kits? how much roughly does a machine shop charge to do the pressing and assembling and how much is the prox kit?

[86 Quad R]

not just anyone can/should rebuild the crank. i use a local guy that specializes in two strokes but there is mrcrankshaft and crankworks. both are good builders and can get the rod kits cheaper.

[riderssb250x]

alright thanks,

where can I purchase the prox kit my self?

if I have somewhere rebuild it will they make sure its also in true or if its out of true does that mean I need a whole new crankshaft

ever have luck with a hotrodcrank?

they are a crap shoot.

I guess I'll chime in here.

Far as cranks, I've had some bad luck with the Hot Rods cranks & then I've had some good results. Some of the Hot Rods cranks have lasted a right good while & then the not so good luck ones only one or two races.
I'm not dissing the product though.

The Wiseco's, they have not been out on the market to long, so you'll only get short term type test results on them.

The Wiseco crank I installed, in my engine, lasted 4 race events.
What happened to it, the tin cracked close by the rod & just so happened at that same time, the piston seized.

Any one that knows me, knows I will run a 2 stroke fat in a heart beat. I'll take that small loss in top power output over spending money rebuilding any day, so its anyones guess as to why the piston just happened to seize at the same time.

What most dont realize, those cranks are mass produced overseas & not closely checked by the producer.
That part is left to the buyer or so it seems.
It was explained to me that, when a shipment comes in, one or two are pulled from the batch & checked real close to see if they are within spec & the others left to by chance be.

I think we can get a quality crank from Hot Rods or Wiseco, but we need to be sure its gone through the quality check before paying the money for one. In the long run, if we all request that before paying, things should get better.

Before any of you jump on your high horse about OEM Honda, been some horror storys about those as well, so altogether, do some checking first to get what your paying for.

I got bit myself trying one out, but if man made it, it can & will break soon or later, some just last longer than others.

[riderssb250x]

so you think i should just try it out?

[C-LEIGH RACING]

If you asking me, I'll leave that up to you, but if you do, be sure to tell them you want one thats been completely checked out.

The one I had that messed up back in Oct, Wiseco replaced it, just came in the other day.
Guess I'll try it out again.
Neil

[riderssb250x]

i see them on ebay cheap im not sure if i should just rebuild my oem , my local dealer ssaid theyve never had anything bad with the hotrods and have used alot of them idk what to do i

[C-LEIGH RACING]

I would say, just as a suggestion, if the OEM one you got not damaged anywhere, like if the tins are scraped up or bent places on them, probably be safe to rebuild it.

Those tin shields on the crank halfs are not real thick & it dont take much of a scrape or bend somewhere on them to cause them to come apart.
Ol crank goes through a bunch of vibs as it rotating in that bottom end & a scrape can turn in to a crack real quick because of that.

Out of the replacement rod kits offered on the market today, the Pro-x is the best.

OUCH,
but, thats a good price cause I checked OEM a month or so ago & it was around 360 something.
I dont know how Eddie get OEM parts so cheap.

Is that retail price.
Neil

[86 Quad R]

neil, the long rod cranks from service honda are now 272.24 retail. :cool:

[riderssb250x]

but you can't buy an oem 86 crank? should I switch over to the 87 rod kit so I can go back to oem or rebuild mine if its rebuildabel?

[86 Quad R]

that choice is yours. i run both and and comination of the two in my R's and like em both. if you now have the 86 setup and you go with the 87 up. you'll need to get a spacer plate.

[riderssb250x]

but you can't buy an oem 86 crank? should I switch over to the 87 rod kit so I can go back to oem or rebuild mine if its rebuildabel?

[86 Quad R]

again that choice is yours and yours only. whether you have your OEM 86 rebuilt or opt to buy the new 87-up crank. either setup will be fine.

[riderssb250x]

well what's the diference in power from the 86 rod to the 87 rod?

would I ned to use an 87 piston?

[86 Quad R]

either rod length can make great power. if going with the long rod you'll want to use the 86 piston with the spacer plate since you currently have an 86 style cylinder. it's not reccomended to use an 87 style piston on a 86 style cylinder due to the port configuration.

[riderssb250x]

im building it as a trail quad would that make a diference will I get more botom end out of one crank vs the other? im really thinkin about doin this since I can get a nice oem crank whick is definatley the best kind of crank and more reliable then a rebuild or aftermarket

how big of a spacer do I need and is that all I need? any crankcase mods?

btw thanks for all the help man I really appreciate it:macho

ya have a pm
