2000 SA50P variatior derestrict
Hi. I just found this site. I am loving all the info here. I just got my 2000 sa50p made in mexico, and before I found the post on here about how to derestrict the variator by removing the restrictor plate, I took the front geared piece that is in front of the variator and ground about a 16th of and inch off of the inside face... you know making it closer to the other cone. Then I took the variartor out and dropped the pipe that is in the center of the variator and I ground about an 8th of and inch off of that.
So this took me from 18 on flat ground to 20 mph. My question is if I remove the restrictor plate now with it cause the 2 cones to be too close to each other? wish I hadn't ground on it now that I found this site and all this cool info.
Thanks in advance.

it was my impression that the sa50P was only designed for 20mph. She has good compression(new rings and gaskets)
I guess it could be running to rich or lean... I have the ring on the needle set at the lowest position and I have replaced the air cleaner box(I wasn't given one) with a piece of sock stretched over the carb opening and then a stiff 8 inchish section of pipe clamped on that. I haven't derestricted the exhaust either... figured I would get one thing at a time figured out.

Number 6
Greetings:
In my case, DayWOT's Keli came with only part number 3 in the diagram, along with six 9-gram rollers. You re-use your stock ramp plate (#7) and the cylincrical bushing (#2). Discard the grease cover (#6), the O-ring (#19) and the three (#15) screws.
Make sure you clean all the grease off everything with solvent or your belt will get too slippery to work. Rollers can be run dry, despite Honda-san's prescription for a bucket o' grease back there. I suspect the rollers need to be replaced more often without the grease bath, but hey - just another excuse to tinker.

I am not a mechanic, nor do I play one on TV. Actually my advice is probably worth slightly less than what you pay to view it.

Re: Number 6
wow. So if I buy the kelli will my shortened "drive face boss" be cool or will I need a new one from honda? The part is only 6 bucks that is why I just ground it...Wheelman-111 wrote:Greetings:

well until I decide to get the kelli variator I will go ahead and take the restrictor plate out and see what happens.qaz wrote:The restrictor plate is number 6 in the diagram. Take the plate off and put the whole thing back together and try it, the variator will only close till the rear plate hits the front plate.
RE: Kenny
thanks... if I want to deresrict the exhaust I am going to have to get a different main jet. will I have to adjust the needle taper also? how does one do that?
Thanks for your help so far everyone! I am glad to have found such a great forum.

Deristricted Jetting
Greetings:
You will need to pull the carb off and remove the float bowl. The main jet is a slotted brass fitting threaded into the center of the carb. I strongly suspect the stock jet is way small knowing Honda-san. The size may be stamped on the side of the jet.
If you know your model/year you can find the stock size of jet at MrCycles.com.
You can order a bigger stock one. The jets all start with the same 5-digit part number, (99101-) then a "0", then the next two digits indicate the jet size in .mm.with another "0" tacked on.
If you have, say, a 55, get a 60 and a couple bigger ones. Order 99101-0**0 where the stars indicate the jet size. Install and watch your plug for a brown color. White means too lean, black is too rich.
Oh yeah, order a new Vario bushing. Your Vario won't be able to shift up to the top with a shortened one. Then again, it might shift up and OVER the top, which would chew up the belt and/or derail it.

Thanks for the info! I removed the restrictor plate and I can clearly tell that I need a bigger jet... It will do 30 with a slight tail wind but I can hear it "running out" of fuel. It would appear from servicehonda.com that it comes stock with a #68 main jet. where would you recommend I start after I derestrict the exhaust? should I start with an 90 you think? It would appear that the stock sa50 comes with a 78 might this be a good starting point instead?

Greetings:
I believe 90 will be much too rich. 78, 82, and 85 will be closer. The 85 is recommended for the stock muffler and carb with the Polini 65.
As a reference, with a K&N filter, ported intake, HMCF reeds, 65cc Polini bore and LeoVinci pipe I settled on a 94 in the stock carb until I got the Arreche.
Stock intake, bore and pipe almost certainly can't use bigger than 88.
Good de-restricting job!
