Many years ago there was a Pacific Northerwest Moped Racing series. It ran from 2010 to around 2015 or so when it ended due to lack of participants. One of the locals built a bike to race one year but it never ended up on the track. That was the Gary Flyer. It passed handed …
I will start with an apology. I tried to craft a reader base and that requires frequent, preferably weekly new posts. I have not held up my end of the bargain. Been so busy actually doing the thing I haven’t had time to talk about me doing the thing. I still don’t, spoiler alert, but …
With about a month left before the races I’ve got quite a lot of work to do. I’ve been making progress but you know how these things go. I’m working on the hobbit engines first so the Tomos is in planning and parts ordering phase. Last time I talked about the rules as I read …
I really enjoy moped racing. I went to the last race of the first Polini Cup in 2009, started a moped racing circuit in the pacific northwest in 2010 that ran for a handful of years, attended Tomahawk Cup, the first 3 Moped GP West, and other various smaller events. Now that I’m back in …
For reasons of data gathering I was putting the stock 14mm carb back on the Tomos. My plan was to put the stock pipe back on and determine the jetting spread needed for fully stock bike with the Bazooka Mouth since I had never done that. I knew the jetting setup from before so I …
I had an idea to have a tool that I could attach to any bike and record acceleration times between any two speeds to aid in tuning. For the express purposes of determing if the bike was getting faster or slower while I was tuning. Smart people might say they already have this technology, in …
I think I am the only person who loves a stock Gurtner carb. Well, not the Peugeot carbs. Or the AR2-10 because you can’t remove the diffuser. But that AR2-12 and the AR1 carbs, that’s me all day. Years ago, when Handy Bikes was a wonderland of NOS parts and lore for those in the …
It’s one thing to do sweet dyno pulls and post graphs that look cool, and I was excited to do that. But ultimately I’d like to sell these as a functional part to the masses that crave them. For that I have to actually test these in the real world. By trade I’m a metal …
So far I’ve done only street testing with a butt dyno, which are notorious for weak accuracy. To be a bit more scientific I called up my friends at Scooter Swap Shop and set up a dyno session on their rolling dyno. They are super nice guys who know their tuning so if you are …
There were issues with the last test part. The rubber was still too soft with the 60A blend and the airbox would try to fall off when I rode. The plan was easy, just get the next harder rubber and make another. Well, thing is, that was the hardest rubber they made in that compound …
