Hey guess, been a while since I've had a bike, but picked up a '78 Maxi in September. Did a complete rebuild (bottom and top end) but I feel like I should have some more top-end speed. Currently hitting 35mph gps'd. Here is my setup:

- 70cc treats kit

- 15mm bing clone with 75 jet

- Proma circuit pipe

- New bearings, seals, stuffed crank

- 3 shoe 6.4 jammer clutch

- 15x45 gearing

The proma circuit is supposed to be a low end pipe, and I bought the jammer clutch to improve low end, but acceleration isn't amazing for 15x45 gearing. I read a lot of you guys are hitting 45 on similar setups with 17x40 gearing, but I can't imagine my acceleration being slower. I ride in Boston so I do a ton of stop and go riding and need good low end, but would love to be in the mid 40s for top speed. I've seen tomohawk mopeds videos on youtube when he's testing customer clutches or a reeded 70cc kit bike and those things fly. Any tips/ suggestions? Thanks!
