Whitey's stroker
Posted: Fri Feb 27, 2015 5:45 pm
Here are some pics on of my 129cc stroker build. I bought this 01 Elite about a year ago. It is in very nice shape and is one of my favorite rides. I bolted a Malossi kit on it last summer matched with a PG long, 24 OKO clone, Keli var and springs. It was great, and was a favorite of some of my friends. I've been selling off those parts to fit the stroker parts.viewtopic.php?f=2&t=30665 I purchased most of my parts from Taida Motor part company. They have many other Dio/Elite performance parts including liquid cooled kits. I chose to go all in and buy the biggest kit and stroke available. From 50cc to 129cc, before I bought this Elite I didn't know that was possible. The cylinder is a 56mm cast bore and the crank is 52.6mm stroke. I have their 120-129cc pipe and the big black manifold from them also.
I strapped my bike down to my work bench to begin the work. Once I stripped the cases and bagged and tagged all the parts I put the cases in the blaster. My brother made this for our projects and it works great. It's so nice to do this in the heated garage instead of in the driveway.
I have a friend do my machining and help with technical stuff. He is extremely skilled and knowledgeable, and is very percise with his work. Here is his current project. http://www.mopedarmy.com/forums/read.php?7,3775171 I just got my cases back from him after he machined them for the bigger cylinder skirt and larger crank.
The crank is so much bigger that it causes you to machine into the holes for the case bolts. I will seal these bolt holes with copper washers and sealant. I have already ported the intake area and sand blasted the metal to give it a even finish.
I still need to match the massive boost port. I took one of the base gaskets and laid it down on the cylinder to match it more closely. Then I will take that gasket and use it to trace the boost port on the cases. I cleaned up the transfers a little and knife edged the dividers.
I did the case match and took the hump out of the intake. It still needs a little more work, then I will sand blast those areas to give it a nice finish.
Finished all the dremel work and blasted all the surfaces. I matched the cylinder slightly where the cases were bigger then the cylinder. You can see some pits in the cases from air pockets in the castings. I might put some JBweld in there to fill it.
Here is the port map of the cylinder.
