Re: 50x50 98cc stroker build
hi forum.
I'm going to install the motor on the spree for tuning purposes.
I don't use the panels and won't have to pull the seat

Hi forum.

Re: 50x50 98cc stroker build
If your plug is shiny black around the threaded area or at the ring it usually means you're too rich on the pilot, if it's shiny black everywhere, on the resistor tip, the arm, and the threads it means too rich all around and you will be building up hard carbon deposits. Being a tad rich is ok for break in, being too rich during break in and you can leave deposits on the piston, head, and ex port which can scratch up the bore and piston later.
Believe me I know it's a pain.
When you bored it to 50mm did you have to cut a lot like the 52.6 crank? Any fear of leaks out of the holes?
I'm thinking about doing a 50 x 50 or 50 x 51 and watching yours and taking notes!

Thank you sir!graphite9 wrote:You don't cut into the threads with the 50. That's the nice thing about that size. Unless you have a sloppy machinist who goes too large.

the 50 will not cut into the holes. there is very thin layer of metal left , more for sealing then support.

Re: 50x50 98cc stroker build
That's awesome! It likes to jump, if you're light it'll be scary.
Re: 50x50 98cc stroker build
Lol thanks 1man. it likes to jump. 7.5gears. it was a little hard to do this video and give it throttle at the same time. the second half I lock the rear break and it won't jump. the video https://www.youtube.com/watch?v=T8iRE50 ... e=youtu.be1man8scoots wrote:That's awesome!

The Yamaha dealer had this Tmax 530 I think they wanted 10.500 for it. it looks cool.
