Trenton Tigney Posted September 2, 2013 Author Report Share Posted September 2, 2013 So I have a stock 110 Vito crankshaft? Quote Link to comment Share on other sites More sharing options...
fappy'97 Posted September 2, 2013 Report Share Posted September 2, 2013 NO. Rod size has nothing to do with figuring out if its a 4mil or stock stroke. Quote Link to comment Share on other sites More sharing options...
Trenton Tigney Posted September 2, 2013 Author Report Share Posted September 2, 2013 Okay when I split the cases , will it tell me on the crankshaft what it is? I have the motor tore apart just waiting on a flywheel puller Quote Link to comment Share on other sites More sharing options...
Pastrykiller Posted September 2, 2013 Report Share Posted September 2, 2013 NO. Rod size has nothing to do with figuring out if its a 4mil or stock stroke. Y29 is the stock rod on a stock crank. It should measure 110. What you have is a possible stock length crank or a 4 mil short rod. Both use the 110 length rod. You will need to look and measure the pin placement in the webs.

Trenton Tigney Posted September 2, 2013 Author Report Share Posted September 2, 2013 So y29 is the same as 110?? What you just said confused me Quote Link to comment Share on other sites More sharing options...
Pastrykiller Posted September 2, 2013 Report Share Posted September 2, 2013 Well I think you need to use the search function. Stock length rod is 110mm. Yamaha does not use the Same verbiage. They use y29 as the marking for the 110mm rod. The stroker question comes up alot in these forums and you should have no problem finding info about pin location. Not sure how else to explain it other than contact a builder and send them some money. Quote Link to comment Share on other sites More sharing options...

camatv Posted September 5, 2013 Report Share Posted September 5, 2013 is your motor a stock cylinder? if it has a spacer plate, or cut up domes its a 4 mill ( unless its a 110 rod). if its a CUB most cubs and cp cylinders have the stroke. bore they were cast for in the intake area. that can be a indication also the easy way to measure stroke is to drop the cyl back on use a pencil or something that wil fit in the plug hole. mark all the way down. the rotate it all the way up. mark there. measure length in mm and blamo there ya go Quote Link to comment Share on other sites More sharing options...

My cylinder are the athena cylinders. An the rods are 110 Edited September 27, 2013 by Trenton Tigney Quote Link to comment Share on other sites More sharing options...
Trenton Tigney Posted September 29, 2013 Author Report Share Posted September 29, 2013 Jesus Christ dude.....all these posts and still seems like your clueless to research.....your best bet at this point is to sell everything and invest in a hot wheels collection ! Your post was pointless. I already got everything straighten out an got it together Quote Link to comment Share on other sites More sharing options...
Pasi S. Posted September 29, 2013 Report Share Posted September 29, 2013 You can have a 110mm rod, stock 54mm stroke. Or you can have stock 54mm stroke with 115mm long rod. 4mm stroker, 58mm stroke you can have 110mm stock lenght rod or a long rod 115mm. Do what camatv told you and measure the stroke from a plug hole. Measure squish also. Quote Link to comment Share on other sites More sharing options...
KaN Powersports Posted November 6, 2013 Report Share Posted November 6, 2013 I realized you said you had it figured out, but for the others as well (I see this question a lot); 1-your best bet is to analyze everything before just tearing it down. Buy a degree wheel and check a few things with it (related to the crank). Set it to TDC for one cyl, then compare against the other. (using the piston stop method) you can easily check the phasing of the crank (making sure they are 180 deg. from each other). Endless resources out there on this procedure-I'll leave it up to you to research out how to set-up/use one.. 2-Measure your stroke (many different methods used) but, for common sakes, the strokes are different enough that even if not super accurate measuring is used, you'll still know. With these two quick checks, you'll know the exact condition (timing/phasing) and stroke of your crank... 3-Proceed to remove the crank, and measure the rod the best you can (center to center) The stocker is 110 and the first common long rod is 115-again 5mm is a pretty big difference, so even if you are a bit inaccurate-you should still be able to tell. 4-All of the standard inspections to bearings/parts at this point Now, if you crank is laying on the bench (or your seeing a used one at a swap meet or something like that) You can eyeball a few things; 1-Look at the big end pin on the side of the web- A stocker will have this pin ABOUT an 1/8 of an inch in from the machined ring that's on the side of the web, A 4mm stroker will have the pin just touching this machined ring. This is crude, but you can quickly determine if it is, in fact, stroked. The most common crank variations between stock and the 4mil are as follows; Of course stock "Long rod" Stock stroke but with a 115mm rod "4mil" 4mm stoke but with a 110 (stock) rod "4mil long rod" The most common "4mil" .... 4mm stroke with a 115 (long rod) Quote Link to comment Share on other sites More sharing options...
dozer Posted November 9, 2013 Report Share Posted November 9, 2013 you can get a printable degree wheel from www.tavia.com. glue it to a old cd and you have a cheap degree wheel. Quote Link to comment Share on other sites More sharing options...
