Best Bang for the Buck, the results - De regulated

[alexfleury]

I posted this pic before of the top speed of my Elite SA50p on my street which has just a slight incline. I started at the same point and accelerated to exactly the same point when I took each pic.

This was my result with the stock bike running uphill



and after the de reg mods



now I also checked the speeds downhill

before the mods



and after



So you can make an elite go about 15 mph faster and accelerate MUCH harder by buying ONE jet for the carb and putting in a few hours work. (and I didn't even buy the jet, I drilled out the stock one)

Congrats. Glad you got everything worked out. Now just about $100 and you'll be going 45-50. Anything after that is bbk.

Just curious, what'd you end up using to take off the variator? Impact wrench or something else to keep the variator in place? Always like to see different methods that people use.

[alexfleury]

I work on Old School Suzukis too so I went and bought a clutch basket tool. I'll use it again.

OK so tell me about this $100 I need to spend. Variator? Be specific, I have a good project coming up over the next 2 months and I'll make a few bucks.

But this is still my looking for the "Bang for the Bucks" so I'm going the cheapest route that gives the most improvement

Kelli variator from daywot on ebay is $48 shipped.
SEF ramp plate and 9:1 gears should be about $65 shipped from VT cycles.
That'll get you to 45-50 mph easily. Especially with those new tires you have ordered.

OK another question

The final drive in my bike is - Final Reduction Ratio: 12.115:1

Am I correct in think that I will lose acceleration and hill climbing ability with the 9:1 gears?

IF I don't do the gears and just do the Kelli variator and SEF ramp plate, what performance difference will I see?

Thanks again for your help. I'm still deciding exactly where I want to go with the bike. I know I'll need the gears if I do the 68cc kit.

Just because of cost and availability I went with the 3.00 X 10 tire.

[bfowler]

Well you will lose a little bit of acceleration but you will gain top speed. And if you tune the roller weights and clutch springs accordingly, you shouldn't notice that much of a difference. If you do the 68cc kit you can stick with stock gears but it wont increase top speed as much as adding the gears would.

That's an impressive gain for drilling a jet and ripping some restrictions off love it

Thanks Pat, believe me if I hadn't found this site it wouldn't have been possible! I do know enough that when I did the exhaust I left as smooth a transition as I could. Porting is very important. I am still going to install the 85 jet when it comes in.

With my engine as it is now, what difference will I see with the Variator and ramp?

I put my first tank of gas in tonight and I'm only getting about 65 miles per gallon. But that is just one check and I was WOT thru almost the whole tank.

I like the bike A WHOLE LOT just as it is. But just a little more ability to run with the 45 mph traffic even if it is uphill would be nice. That's why I am thinking about the BBK and keeping stock gearing. But one thing at a time. I am leaving to go to a new project for a couple of months and I think I'll put the bike in van and take it with me. So I probably won't do much to it until November. Time to just ride it awhile for now.

I still want to keep this a "Best Bang for the Buck" project so that a broke a** college student or somebody who just wants some basic transportation can get by as cheap as possible.

Actually the bike is fine for running around town errands just as it is now. But I want to make it practical for most any kind of every day use.

you are at the top speed for the stock gears.

9.1:1 or 9.8:1 final drive gears work well with the stock 50cc setup.

top speed will improve down hills but uphills will be unchanged until you get more power from a bbk.

[LMH]

How does mine go this fast with stock gears? 99 elite sr with stock gearing and stock cylinder. Does his have a different stock ratio? Even before any mods I hit half way between the 35 and mph gauge.

[Trafficjamz]

39.9 mph on gps is all I have ever seen out of stock gearing.

Differences in tire size can show huge variations in the stock speedo.

Take a video of how long it takes to reach that speed. I have forgotten what 50cc is like.

[Jam-bro]

Are the carbs on the S and the SR the same? Service manual shows a different part number for each..

[Trafficjamz]

same carb different jets

[Jam-bro]

Traffic, are the jets the same type as in the Spree?

Same type , Yes.
