 OK, I can't explain either why this image is sideways, or why it's showing in such lower resolution than makes sense to me. I'm going to lower my blood pressure by quitting trying. What excites us about this bike is this: This is the 2012 model of the Legend. These are the last of the BMS Legends, and there's no word about whether they're coming back. They appear to have come out of that era right before BMS decided that everything they did was going to get chrome. So, we looked at the black muffler guard and a couple of other things and said THIS is the bike we're going to beef up beyond all recognition. Here is the chance to get in now with suggestions. Some of them I've heard, MANY of them I've read. We're going to do this up as far as reason allows. Any suggestions on the best BBK for a 150cc that we can put in without major boring or overhaul? How would you jet? Tell us what YOU would do to make THIS bike the performance dream machine. I'm going to start ordering parts on Monday, and immediately put our new mechanic on working on it at least a little every day he's in... our hope is to have a beautifully customized dream-scoot ready for sale in a couple of weeks. Please help us get there! |

Please help us get there! If you really want to go performance, I would not rule out boring the case. It can be done with a drill and a $150 tool. If I did a big bore, and a big cam, I'd want to make sure my bearings and case, as well as the variator and belt, could handle the extra stress. How this information is found, I have no idea. Maybe there's a book on bearing and housing thickness vs horsepower somewhere? Short of that, everyone seems to like "free flow" intakes and exhausts, BBKs, stroker cranks, lopier cams, and "performance" coils and things, and with more horsepower comes variator tuning and possibly a drive gear change. You might put a picture of a hornet on it to warn people that it's got a powerful sting in spite of its classic scooter look. |

So, keeping in mind the bearing and case comment from above, but not yet giving that the full weight of consideration we're probably needing to, we're leaning toward a few items to start: Here are some links for your evaluation, comments, etc. I don't feel confident in my ability to bore, and I don't know my new mechanic well enough to trust him to do it yet, so here is the bbk we're considering. I've read several posts on the old board that discussed this, and I think it will meet with some approval. www.scooterworks.com/ncy-cylinder-kit--aluminum--61mm--171cc---genuine-gy6-products-1028.php#.Vdp21ZdZii8(This, and several other items, are contingent on our being able to set up a dealer's account with Scooter Works, but I understand they're easy to deal with). If you're going to do the bbk, might as well go ahead and put some additional air through the thing. Stock carb is a pretty nice Deni, so we're going to re-jet to 31mm... I'd appreciate advice on that, because I could be thinking about this wrong). We are planning on pairing the Uni UP-4182AST Angled Dual Layer Pod Air Filter ( www.partsforscooters.com/230-33-Uni-air-filter-for-full-size-scooters ) With this beast of an exhaust: www.partsforscooters.com/Performance_pipe_GY6?sc=34&category=132557 (though if anyone has used it and can give me a review, I'd love to hear it... it's really pricey, and if it's not all it's cracked up to be... still, SO... PRETTTTTTY...) To keep the whole thing cool, we're considering this: www.scooterworks.com/ncy-oil-cooler--gy6--genuine-products-495.php#.VdncN5dZii8 I'd love to hear that the 29 dollar ones from Monster Scooter Parts work just as well ( www.monsterscooterparts.com/oil-cooler.html), so if you've actually used one and it rocks far greater than it's budget price would suggest, then please let me know. Haven't spent any time on variator weights yet. We will be installing a Gates Premium or Bando Kevlar belt in the next few days. Have discussed cdi/ignition coil mods previously, but wouldn't mind opening up the floor to that if people have thoughts. Thanks again, all, Shanty |

Scrappy dogs has an oil cooler for less than 100 bucks that has the fittings that replace the oil screen bolt. Oil coolers alone (like the monster one I believe)are cheap but most youll have to rig up some sort of fittings or buy the modified case. Theres a 200 buck kit too but thats reaaally pricey I thinks. I dunk about the quality of the cheaper one but I like the price. Seems like unless you live where its really hot, get a gigantic cylinder kit, or ride constantly wot you probably wont need one though and the money could be spent on speed upgrades

ScrappyDog, please tell me, how is the quality of the "GY6 retrofit oil cooler kit" when compared to the NCY?

It sounds like a lot of fun. I would break-in that scooter by the book before doing the hop up.
