As far as you know, is the only advantage of the aluminum version the fact that it’s a little lighter? Lighter and helps cool better. More towards the performance side of things. Right on. That’s what I figured. Thanks. You can have your thread back now. |

Would a softer or firmer rear shock help with the wheelie prone scoot, well to get up easier. The front wheel that is...
Shims out of the variator, heavier weights 5.0gr now and a spacer on the TD spring. It’s ready to boogie. Really I think 4.8gr will be ideal. It’s at 11,200 now and I want to be at 11,500. The ignition has completely changed the exhaust tone, it sounds angry now. Time to go find a parking lot my neighbors are probably getting annoyed at the grown man on a scooter ripping up and down the street by now.

As far as you know, is the only advantage of the aluminum version the fact that it’s a little lighter? I've had the steel and aluminum Malossi TDs. I would actually put the main advantage as a more robust design. I had a steel OR pulley come apart while riding once. Not cool. The aluminum pulley is well built and seems to be more precision built. The steel pulleys always look like they're out of round or bent if I spin them. Generally nothing that has any real affect, but the aluminum pulley isn't like that and it really shouldn't be with CNC cut drive faces. That said, If I couldn't modify them, I'd choose the steel one all day. I had to actually work on my aluminum Malossi pulley to make it work like the steel versions that it is alleged to be superior too. I think the thick aluminum construction caused some compromise that altered the travel. Not that it would be bad out of the box, but it's a shame to see them design a next gen product that is worse in some aspects. A small amount more time in design and they could have had a performance equal with better construction and cooling. I weighed them I think, but I don't believe it was a really significant difference. I may be mistaken though. I can't recall for sure. |

Would a softer or firmer rear shock help with the wheelie prone scoot, well to get up easier. The front wheel that is... There seem to be different schools of thought on this. I kinda think you need to find out what works for you. Some say soft and some say stiff. Thinking about the stiff suspension side, I imagine it as stiff as it could be... solid. There's nothing to waste energy and all energy should be transferred. So that sounds kinda good for a wheelie. Then think about a soft rear suspension though. If the shock will compress a bit, it would let the bike begin to take on the upward angle and transfer weight toward the rear. I think rebound settings may be easier to grasp for this, at least for me. A strong/fast rebound up front would want to let the front extend or push up. A slower/lesser rebound for the rear should would make it not try as hard to get itself level again. I may be wrong about it all though. I don't claim to know much about suspensions. |

I would think a softer shock would make wheelies easier. More weight transfer to the rear would make the front lighter.

I was kind of thinking the softer shock theory also. I can test out both and makeup a solid strut or just firm up my shock. It’s currently a little on the firm side.
I’ll work on getting some video over the Holidays, I’m happy with it to say the least. It should make for some good “Zero to” clips.

It’s been awhile since you’ve seen the girl, also my stator cover plate.   |

If that's the case, why do you think the aluminum version of the Polini over range would be less expensive? I was going to go with the iron version because I figured the opposite would be true. Not sure what to think now.  |

Not sure what to think now. To be fair, I know nothing about the Polini pulleys. Could be totally different. From pics that I've seen, the Polini aluminum looks much closer to the standard design that we see with iron stuff. The Malossi aluminum on the other hand has big thick sections where things are riveted together and overall is very thick. |

ryan_ottDo you know the length of the brake hoses, front and rear, on your build?

ryan_ottDo you know the length of the brake hoses, front and rear, on your build? I’m not certain but I’ll try to measure them later. The rear is Aerox, and the front is from a prebug. |

tsimi the front is 44” and the rear is 78”, these are appropriate. I tried to follow the lines with wire and then measured that.

Ryan was kind enough to take some measurements for us from his EPROM ignition. I posted them in the link below, but I wanted to share them here as well. Thanks Ryan! 49ccscoot.proboards.com/thread/26257/dd06-ignition-info-timing-graphs  Odd how there's MVT 1, 3, 4 and 5. No MVT 2 setting. Made me wonder if they're too proud to say that any of their curves are #2. |
