Hello,
I have an appointment to purchase a restored 1959 Allstate this Saturday from a private party. The scooter was restored by a local shop here in SF and the gentleman that did the restoration has been very helpful. The seller is not giving it away but considering I don't have to do anything to it, and looking at what I think the market value is, It seems a fair price or at least one I can live with.
I have been reading through many of the recent posts on this site and trying to find as much info on the internet as possible related to this particular scooter and am finding it pretty daunting. It's not real clear what motor came with this year or what type of induction. I am not sure even sure the motor in it is original or date correct. My concern is, I am purchasing it for the fun factor but also so (after COVID) my wife and I can get around the city without having to deal with traffic and parking issues that come with living in SF. I understand that this scooter was a dog 70 years ago, add my fat ass and my perfectly shaped wife to the mix and it might be a challenge to not get ran over. So, I have been trying to figure out what I can do to put a little pep in the old girls step. It seem that I can't do that without knowing exactly what motor I am dealing with and the reason for this post.
Once I have position, I can check the model on the engine easily enough and expect it to be a VNA type motor. It's my understanding that the VNA came in both piston ported and rotary ported. I think the difference is where the carburetor sits in relation to the motor but I don't actually understand the difference in the motor itself. I have seem posts that say the piston is better and I have also seen it said that the rotary is better. Then there is the issue of what can actually be done to it. My only experience with a two stroke scooter was when I was kid and had a Yamaha YSR 50. I rejetted it and put an aftermarket pipe on and it went from 30 to 65 MPH and would pull wheelies in the first three gears. I do know that whatever motor is in the scooter was completely gone thru. Would the rejet/pipe approach work?
If I could get some advice on how to determine the motor I have and what my options are for increasing low end acceleration, it would be very helpful.
Thank you in advance
