From Mild TO Wild! Posted January 8, 2012 Report Posted January 8, 2012 The long rods hit because i didnt clearance enough and the squish is .019. So it has to come all the way back apart again. Also thick base gaskets. This is just awesome. Any input would be nice guys. As in any short cuts. Thanks and I hope this made you laugh. Quote
werner Posted January 8, 2012 Report Posted January 8, 2012 what base thickness are you running. what domes...custom cut or ProDesigns? Stock cyl or cub Quote
From Mild TO Wild! Posted January 8, 2012 Author Report Posted January 8, 2012 Stock cyls stock base gaskets and milled and decked stock head. Quote
Surfrjag Posted January 8, 2012 Report Posted January 8, 2012 Did you have the cylinders ported? I would consider checking port timing to see if its a base gasket or head issue. Check with whoever did the head and cylinder work as well.. Quote
From Mild TO Wild! Posted January 8, 2012 Author Report Posted January 8, 2012 (edited) See the shaved stock head i bought off a member who said it was setup for a 4 mill. I bought the 4 mill ported cyls second hand so i had no idea on what gaskets to use. I went on assumption. I was wrong. So knowing my squish is .019 ill get .030 base gaskets. Its the crank with bronze rods, I guess its a rather popular thing to have to do for these cranks. Does anyone have any ideas to clearancing the top of the case to allow the crank to rotate freely but not separate the halves or do you guys think its not possible? I know metal shavings are bad but if i can flush them out or whatever id rather do that instead of having to fully take it apart again. Any ideas are appreciated.

J.J. Posted January 9, 2012 Report Posted January 9, 2012 Split the cases. I haven't heard of too many 58mm stroke (4mm) x 115mm cranks that needed clearancing at the upper case, mine certainly did not. Quote
mikechief Posted January 9, 2012 Report Posted January 9, 2012 if your jugs a ported and you start stackin up base gaskeests you'll end up with crazy exhaust timing . It would be best to get your head set up right . You can get thicker head gaskets which wouldn't mess with your port timings . Quote
From Mild TO Wild! Posted January 9, 2012 Author Report Posted January 9, 2012 .060 base gasket is on its way. Fixes squish. The pistons are wiseco prlites 65mm. Yes they are 795 series pistons. Quote
badassbanshee479 Posted January 9, 2012 Report Posted January 9, 2012 you shouldn't have to clearance anything for a 4mill long rod crank unless it has 120 rods on it for some silly reason..... also stacking up base gaskets is not a really good idea.... like mentioned above have the head cut by a reputable builder and do it right.

From Mild TO Wild! Posted January 9, 2012 Author Report Posted January 9, 2012 What's the crank to buy then? Quote
papa_smurf49319 Posted January 9, 2012 Report Posted January 9, 2012 Hot rods, or one from Andy at m&m. Built 2 4 mill long rods, and no clearancing for crank!!!!!!! Quote
mike0chek Posted January 10, 2012 Report Posted January 10, 2012 my 4 mill was catching in a similar way when i put it together, it only caught when the rods were at an certain angle tho, an angle that would never happen when the cylinders are on. hope that makes sense lol Quote
