Re: Elite 50 YMS V8 muffler - best set up???

I have tried that pipe with a stock bore, even my ported stock bore that does 52 mph. I had the same reults as you and had terrible low end. The only way I was able to get a some what decent result was to put on 3000 rpm clutch springs. So in theory the clutch kicked in at 4000 rpm. Even with this, ...

Re: SYM DD50 Build...

I'm still on the fence about which cylinder kit to run first. Either way, I'm planning on keeping the other to run at a latter date. I was very interested to know the differences between the two. I was very sup prized to find out there not as different as I had thought. I put my wonderful girlfriend...

Re: SYM DD50 Build...

I picked up a few goodies from Red Eft Performance. I'm not going to lie, we did run in to some issues with incorrect part numbers and I did end up getting the wrong part. What makes a good company or person for that matter is how things are handled when things go wrong. And I can happily say that o...

Re: SYM DD50 Build...

I think what Red is saying about the CT leaking is very likely. I personally smoothed out the casting flaws on the mating surfaces of the mani, which should reduce the tendency of it leaking. Here's a pic of the flange surface out of the box. http://i1211.photobucket.com/albums/cc431/donmoped/DSC062...

Re: SYM DD50 Build...

As far as I know, you want the inside surface texture to be a little rough. Supposedly its going to help keep the fuel suspended in the air and help keep as low of a surface tension for better flow. If its smooth the fuel will tend to stick to the walls and not atomize. The exhaust you want smooth t...

Re: SYM DD50 Build...

Ok, I'm pretty much finished with the intake manifold. Does anyone know if I can remove the reed stop. The reed setup consists of the reed block followed by the reeds followed by the reed stiffener, followed by the reed stop plate. Can I remove the plate? Or the stiffeners? Here's the competed manif...

Re: SYM DD50 Build...

Emailed treatland they said its for a 70cc. They actually said they don't know much about the pipe. They just stock it for there friends in Hawaii. I guess someone from here has been ordering it from them. Basically looking for a street race setup. Something that will pull nice and hard from stop to...

Re: SYM DD50 Build...

Anyone got info or has tried the somini pipe that treatland carries?

We can get the Sef, scorpion, and pg stuff here locally, but does anyone have a good source for arrow and the other types of pipes. There getting harder and harder to track down.

Re: SYM DD50 Build...

Oh, and yes I've seen that "dental" porting tool you speak of, but at $1000 it's pretty steep, especially for someone that may only be porting one cylinder. I was actually thinking of picking it up to try, if we weren't slow at work I might have bought it. Oh well, maybe some other time.

Re: SYM DD50 Build...

Ok, that's some sound advise. No since making the cylinder to a more aggressive spec if you can't find an exhaust to match. Talking about exhaust... what exhaust out there would you recommend that would match up well with the corsa. Pg long (loud barking sound) as BAKA stated, he also had recommende...

Re: SYM DD50 Build...

Here's a little entertainment. It's a video of my buddy and me playing on a mountain road. The camera is on his bike and he's chasing me up the hill. He's on a R6 and I'm on a 636. ENJOY! http://i334.photobucket.com/albums/m438/DONAUDI/th_CraterRun.jpg Here's the same run, but the camera is on my 63...

Re: SYM DD50 Build...

That't the funny thing. All this "extra" work may not this motor any faster than someone who just bolts on the parts and go. If there is any diffrence, it will be small. My thought process behind doing this stuff is: If you purchase the parts why not spend a little more time and get the pa...

Re: SYM DD50 Build...

I'm by no means an expert in any way shape or form. I'm doing this to show that with a dremel, sand paper, spray paint, and some patience anybody and do this type of stuff. And more so, I encourage to do better than me. This is all that I can think of doing, but I know a lot of you guys are way more...

Re: SYM DD50 Build...

I have another question.. I'm going to "knife edge" the bottoms of the transfer ports and possibly open and smooth them out a little. Is there any advise before I proceed? Beside matching the cylinder to the base gaskets? Also I wanted to widen the exhaust and transfer ports a little as we...

Re: SYM DD50 Build...

Two questions.... 1. I was contemplating painting the intake manifold black like the carb. What do you guys think? Too much black? Still on the fence. 2. Here is a pic of the reed block. I have read you need at least two millimeters to have a good seal for the reeds. I was thinking of opening up the...
