Yup.....got some coming for testing. High silcone content wire, similar to that used in NASCAR spring windings. No, not Titanium, but NOT an OEM spring that has been Titanium anodized(just to part a fool and his money) either.
Besides.....looking like an AFFORDABLE price range IF they work out..... somewhere in the $20-24.00 price range for a pair of inner and outers.
Keep your fingers crossed, good springs, no coil binding, and affordable.....this will be sweet if it works out!

im still in the market for some ..........of course with those on one of my scoot engines if they dont give then i guess ill end up snaping a valve or rocker arm when i over rev lol cuz boys and girls........its what i do lolyea ith the new longcase and 13'' rear wheel , i got caught in the slipstream of about 7 cars running down a flat stretch of road they kept accelrating and i kept following suite, i hit an indicated 77mph (62-67 real mph ) and was still climbing but had to back off to avoid getting intimate with the truck in front of me .......tells me one thing scooters with me on them are about as aerodynamic as a toaster!

maybe I am wrong but I believe on these small engines the head is the most important single item as far as extracting all of the power possible. I will be looking at those springs real close. John

So how do you go about testing these springs. Just check the tensile strength or are you going to set up some kind of equipment that compresses it a high number of times and frequency?

As long as the springs come from a reliable source and were designed for the application, you don't need to do any fancy testing. like Kliff alluded to at the start, this isn't rocket science, just doing the job right. You might want to check for springload with the valve seated, spring rate and coil bind, but that's about it. The Japanese were making motorcycle engines that would turn faster than our scooter engines all day long 40 years ago using well designed non-exotic springs and they were reliable.

Just food for thought. be carefull about to much spring pressure because it can pull the head right off the valve. It seems to me the stock valve is built from using 2 pieces. 1 the stem and 2 the valve head. they are machined welded together. This is very common with stock valves. They break right ware they are welded. Been there done that.

The Japanese were making motorcycle engines that would turn faster than our scooter engines all day long 40 years ago using well designed non-exotic springs and they were reliable. Exactly, like XS says. testing is going to be more a matter of geometry on my end. Will the final product fit, maintain coil clearance at max lift, inner and outer, install at an acceptable height for idle seat pressure. Sverral hours of R&R....test springs with cam & dialindicator, cam & new inner springs, cam & new outer springs, rotational tests, check for "rubs," any pre-install polishing needed between springs. Like I've said before, "plug & play," is nice, quick, & easy, I'm 99% sure these will work rat now. But if even an extra 3-5% increase in power or longevity is there, with another few minutes work, another shim....whatever. Would YOU want to know about it? Would you want me to set them up, polish, relieve, or resize, or would you like the info so you can do it? Or would you prefer someone to hold out there hand for money, give you the springs, then tell you to have a nice day? I trust the spring man. to have sold me a spring that will provide 40-50lbs seat pressure, and 80-100lbs, over the top, BUT, it is a Hi-Perf part. Bad tings can happen with stuff like this. I'm going to try to make them available SHIPPED, in the lower USA for $32.00. Not as cheap as I'd hoped, and yes, I'm gonna make a couple of bux. But I ain't raping no-one for 65.00!!! That I will guarantee! More info next week.

Yup.....got some coming for testing. That is what I was curious about, so the testing is putting them in and seeing how they go. Having read a lot of your posts, I kind of thought you had a more extravagant method.

Keep your fingers crossed, good springs, no coil binding, and affordable.....this will be sweet if it works out! Yes, but face it. If they come from here they'll be more consistent in quality and have a little more ability to stand up to abuse than the "Angel Hair" springs that come stock in many China scoots. Even if you don't use them for high performance purposes. The springs that kliff put in my head look a darn sight better than the stockers so I expect those to last longer than the rest of the engine. I've dropped my rpm in daily use to be on the safe side but at least I know I'm safe from sudden spring breakage. If these turn out to be good then a few bucks for springs will seem like small potatoes in comparison to pulling the engine to replace valve springs every year, or worse.

Hey!
What are you guys doin here? I feel like all my friends went outside to talk, and no one told me. Was it something I said?
Great to see a new forum!
Kliff, got your PM. Sign me up for a set of these springs!
Nothing else needed to add in a new cam?
