geh3333 urbanmadness dmartin95Rhode the scoot to work today and I am not sure if I can go a bit lighter on the rollers. I really wanted to. To me it does not sound like the scooter is screaming but the tachometer seems to indicate otherwise. I do notice that my idle goes up after 30 minutes of riding it seems to idle around 2200 rpm, if I lower the idle it would be fine but then on start up it give me problems. On straights I am not really going over 7400 RPM, occasionally I was hitting 7700 RPM on some down hills. I am on 12 Grams rollers now, wanted to put on 11 Grams DR pulley sliders is that advisable? If it is 500 RPM increase per gram, that would put me at about 7200 RPM on take off and hill climbing and 7700 RPM on flats and 8200 RPM on slight down hills. Does that sound dangerous for my engine? My scoot is a Znen so supposedly should have better internals then a tatao.... Thank you

That's not a bad price actually. it was a bit cheaper when i got it @ 24.99... The big chrome ones look nice but they look a bit difficult to hook up and you need additional cable. This one only needed one wire to be wrapped around the coil. I was able to pass the wire underneath the front fender using a metal coat hanger. Metal coat hanger first and then wrapped the signal wire around wire metal and taped it and pulled it trough... it worked... wish the signal cable was 6 inches longer and I could have mounted on top of the starring wheel... currently it does not reach. The signal wire is about 3 feet if I had to guess. Hope this helps.

Do you think my reading correct now with the way I have it set up? You never said how you hooked it up, but if your numbers are around 1500~2000 rpm idle and 7~8000 RPM at WOT I'd say yes... Those are the numbers you should be at. I wrapped the signal wire to the ignition coil next to the spark plug. Tx

No joke. I read online our temperatures are around 350F or 180C about. I also had found some info on that gauge and they stated it would go all the way around... I can tell you for sure it is much higher then 90C That is the reason I would love to find a reasonably priced 400 F or 200 C gauge. Well, if you read it online, then it must be true. haha, you stand correct. All I know my car which has an oil cooler runs @ 240 F

lol... that was + whatever a full revolution is... so > 190C Hehe not sure if I missed a joke there. It's 90C so that's about 194F. I read one one website that it should be between 180F and 200F. No joke. I read online our temperatures are around 350F or 180C about. I also had found some info on that gauge and they stated it would go all the way around...

I think the GY6 sparks every revolution, even though the actual combustion only happens every other revolution. Yes, you're correct.... You have a pickup coil that goes over top of your flywheel, that flywheel has a big magnet on the top, everytime that passes the pickup, it fires,,,... However, It fires to the CDI... From there, the CDI only produces 1 pules per RPM... That's why if you hook up a tachometer, you have to connect to your pulse signal coming out from your CDI and not the pickup coming in..... Do you think my reading correct now with the way I have it set up?

Ohh sorry to hear. Hope no one got hurt. I am thinking about buying one, but I would like one that goes up too 200C or 350F. Having a hard time finding one reasonably priced... Thank you No. No one got hurt. Just me. :)I see ones like mine on ebay for under $10. My oil temps were around I think. lol... that was + whatever a full revolution is... so > 190C

No sorry. I was in a wreck a month later and the thermometer went with the bike to the insurance company. Ohh sorry to hear. Hope no one got hurt. I am thinking about buying one, but I would like one that goes up too 200C or 350F. Having a hard time finding one reasonably priced... Thank you

You have enough room to go with 11.5 grams rollers. That should get you up around 7500 7700 RpmS . you have to stagger 12 and 11 grams weights. I only went for a 1/2 mil drive. I will take it to work on Thursday and see what are top RPM on long stretch and report back. Ideally I do not want to go over 7500 RPM on flats? is that the rule? Thank you

Can I use sliders instead of rollers? I am really tempted to try 11G sliders... would that cause me to over Rev?

geh3333, I took a video but I am not on wifi right now and I cannot upload it, but I will as soon as I can. Anyway Played with the settings and the best one was 1 spark per Revolution even though according to the instruction for 4 cycle one cylinder it should be 1 spark 2 revs but my scoot did not like that setting as it stated it was idling @ 4k rpm.. :-) went for a quick spin to check RPM and I am a bit disappointed that RPM seemed to be perfect... I was hoping to be able to lower roller weights a bit but I am not sure it is possible.... On take off I was just @7k RPM and then RPM would stay at around 6500 RPM all the way up to 55MPH and then peak about 7200 RPM at 60 MPH. I am on 12 Grams Rollers, wanted to try perhaps 11 Grams DR pulley sliders but I think I would reving to high... Opinions? those are not GPS speeds... so take that with a grain on salt.. MPH are a bit off. Thank you
