sheerider11 Posted February 17, 2012 Report Share Posted February 17, 2012 It's coming from east coast atv. There pretty cool there. Some people doing like vitos tho. Its a 110 rod. So that's a short rod. I have the same crank. People say it puts more side load on the piston and wears faster. I have yet to see proof. I haven't had any problems with that crank yet so I'll approve of it as of now. Quote Link to comment Share on other sites More sharing options...
andrew3160 Posted February 17, 2012 Report Share Posted February 17, 2012 Ditch the spacer plate and get cut domes and porting. You will be a lot happier ! Quote Link to comment Share on other sites More sharing options...

andrew3160 Posted February 17, 2012 Report Share Posted February 17, 2012 I believe your porting will have to be changed still if you put a 4 mill in it. Your current porting is for a stock stroke. Call a site sponser and tell them what your looking for and how much you want to spend. I use Jeff at FAST and he is great! Quote Link to comment Share on other sites More sharing options...
Burt Reynolds Posted February 17, 2012 Report Share Posted February 17, 2012 (edited) Wait your at 64.5 and you want to jump to 66? Why would you throw away 1 and a half mm of bore. See if they can give you the kit with a smaller bore piston. I have ran 4mils with spacers and cut domes,cut domes are the preffered method,but spacer plates will work. If your cylinders are ported though,and you throw a spacer in there it could throw your durations way off and make it not run very well Edited February 17, 2012 by Burt Reynolds Quote Link to comment Share on other sites More sharing options...

You can piece together a kit for under 700. no it comes with whatever size piston kit you want Quote Link to comment Share on other sites More sharing options...

andrew3160 Posted February 17, 2012 Report Share Posted February 17, 2012 porting on jugs or case? Jugs, nothing needed on the cases with a 4 mill, Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted February 17, 2012 Report Share Posted February 17, 2012 Porting on the jugs. The plate kind of mimics getting your ports raised by doing real porting. I had my cases port matched to the jugs and the jugs ported for my 4 mil. Quote Link to comment Share on other sites More sharing options...
Burt Reynolds Posted February 17, 2012 Report Share Posted February 17, 2012 I mean when you had your cylinders ported,they raised the port roofs,if you use a spacer it will raise them even higher. If you throw the kit together with no additional porting,it will run,but it may not be optimal. Sometimes port jobs can be changed to work with 4mill cranks to make it right,sometimes they cant. Before i spent 700,have your cylinders looked at and find out exactly where your height and durations are,then someone who knows about porting can tell you exactly the right way Quote Link to comment Share on other sites More sharing options...

He is right about the porting. A lot of times the transfers end up way too high leaving you worse off. Quote Link to comment Share on other sites More sharing options...

A lot of times the transfers end up way too high leaving you worse off. among other things that make the low end response even worse... so take an already somewhat pipey motor and make it really pipey! ditch the plate.
