I'm just planning on dropping about $150 on a beefy crank(and hopefully forget about it for a long, long time), and probably a new oil pump/seals. I haven't explored the strokers yet, but I do read what gets posted about them. I've considered doing a top end on mine... I have 7k on it.... but if it's not broke, why fix it? Were you considering, whenever that may be, on just a stock rebuild or a BBK? |

Those 3 V-shaped variator plate guides scare me. Those things are such junk.

Were you considering, whenever that may be, on just a stock rebuild or a BBK? Most likely stock. It's a 150, so to really benefit it would have to bored, and stroked.... I'd be better off putting the money into a motorcycle. I think, by far, on a 150, tuning the variator is the most bang for the buck. The other challenge on my bike, is finding an aftermarket exhaust that would fit under the plastic correctly and if you are going to stroke it, and bore it, you don't want to use the stock exhaust... it's just not going to ever realize it's full potential. Add to that, the bike is currently for sale... again to add to the motorcycle fund, and the rate of return on a BBK, just isn't worth it to me. |

My scoot is an in town driver only I take the car if I have to hit the highway 70 zones so my 150 is more than enough for what I do with it.I like to work on it is why I will upgrade it every 5000 miles just preventive maintenance.

Mine doesn't run in town too much.... I take main roads kinda like expressways. I run with traffic that runs 50-55 mph, and I run those speeds for miles and miles at a time. The biggest reason I switched to a 115mm variator was for a higher cruise speed. |

The biggest reason I switched to a 115mm variator was for a higher cruise speed. Same here but I traded in the 150 on a 250 after the last time I got it running right and get much better fuel economy at those speeds with the 250. A co-worker just upgraded to a 300 and was pleasantly surprised to see a drastic improvement in fuel economy riding the 300 to work each day over pushing his 150 along at 50+ mph. |

Wow!!! Thanks for all the positive replies,
I!'m glad that I 'm not the only one to have a relationship with my scooter.
I could buy myself a new scooter anytime but to learn how these machines work is a wonder. Still learning about the gy6 for now.

I've changed them out several times over time. They definitely need changed out once a year, and probably closer to twice a year with or without BBK, or just lot's of riding. I buy 2 sets just to have a spare set on hand. Nothing like a $3 or so fix to keep you off the road, and possibly a new variator if you go too long without replacing/checking, before catching the culprit. I've had that happen. |

Whats a little variator rattle amongst friends? When the plastic/delrin/teflon guides wear out the metal parts then wear out pretty quickly don't they. Getting a good quality set does help. Sometimes on items like these we shoot ourselves in the foot to basically save a few pennies buying for example 75 cent each guides instead of the $1.05 ones. |

I also think there may either be:
A) 2 different back-plates, with different sized grooves where the v-guides fit into, or B) 2 different sized v-guides. Both being black, and not being sold as better quality---as stock replacement for the 139qmb variator.
I could barely get the back plate on last time, after installing new v-guides. They just would not fit all the way into the grooves like they have in the past.

Dr. Pully may have some of the better guides out there. If they are too tight a little dressing of the nylon guides with a fine file or hone may be all that is required. |
