They do sell 11.5 dr pulley rollers or sliders. I just don't understand why 1 gram would make my rpm climb by 1k? Do 11 gram slider vs 11 gram roller yield same rpm? Or slider cause higher rpm? I was just researching this! I havent used sliders in a few years and can't remember. I found a few people said they had higher cruising rpms. Pretty sure Alleyoop, and a few others, recommended to go up in weight when switching to sliders-- don't hold me to it though, lol. Edit: here's one of the many threads itistheride.boards.net/thread/6816/rollers-slidersEDIT#2: I've read to where people said it didn't make a difference either way, too. Not sure I'm convinced either way. |

If you don't get sliders, why not just get 11.5g rollers? With 12g you are already pushing 8,000 downhill and not quite 7500 on flats. From what you've stated, 11.5g will push you over 8,000 downhill and should easily reach 7500 on flats. You could then try mixing the 11.5g and 12g weights, if you ever feel you need to "back off" the throttle without literally doing that. Unless you want to go over 8,000rpm.
Remember the rpms will slowly rise over time as the belt wears-- if your belt is brand new those 12g might not be so bad after putting some decent miles on it.

geh3333 lain It seems sliders do increase RPMS. It does make sense. At least from what I am reading from other posts online, people using same wight sliders were getting higher RPMS. If I am hitting 8K rpm on flats on 11g sliders, should I use 12 grams to lower my rpms to about 7500 on flats? does that make sense or should i go even heavier? Man this is another $20... lol Thank you

Man this is another $20... lol Thank you That is true , usually you will go a size heavier when switching to sliders. Or if you are running slightly low rpms with 12 gram rollers , you may want to use 12 gram sliders . this is going to be a tuning process and you may need to purchase a couple sets. You can get koso rollers on eBay for under $10 shipped to your house. The one thing I do not like about sliders is the possibility of one or more flipping out of place. I've had it happen a number of times . that's why I don't use them . some like them and some don't . |

I decided to follow your advice and mix my 12 grams rollers with the sliders. I'll let you know how I make out. |

FYI- even though there is only one combustion event every 2 revolutions, the plug does fire every revolution on a 4 stroke.

Id mix 12 gram rollers with 11 gram rollers . I know u don't have the 11 gram rollers yet . I have a set of 11 gram rollers if you need some " free of charge " I'm actually dead broke till Monday so if you send me your address I can send them out Monday. I'll have to check to make sure I have a good set of 11's just to be sure. |

However I did read in some older forums where this was done with very good success so I will give it a try. scootdawg.proboards.com/thread/50353?page=1#shineAnyway hopefully in a month or so I will be fully upgraded to the 61mm and will be changing weights again  |

Just installed the 3 11g sliders with 3 12grams rollers. Put it all back together, but could not take her out for a ride as it is raining. It supposed to rain tomorrow as well, hopefully I can post an update on RPMS Sunday. I was happy that my sliders did not move after 150 miles.

Wait a minute. On every down stroke the intake valve is open and on every upstroke the intake is close and the exhaust valve is open . so if the plug sparks every revolution then how does it not combust on every revolution ? Am I missing something ? I mean , the intake valve must be open on each down stroke . if not , the piston would not be able to make the downstroke " because of suction " . just as the exhaust valve must be open on every upstroke. If it wasn't , the piston would have a heck of a time making that upstroke. So every time the intake valve open , the piston sucks in air and fuel . so if the plug fires every revolution , then there must be combustion on every revolution. The piston has an up and down stroke on every revolution, so there has to be combustion on every revolution , right ?
