Yes. And yes, I would like to see your tits.

Thank you all for the kind words. I can assure you all I'm almost as surprised and impressed as you. This thing came together fast and it's a real looker.

I've spent the last two evenings after work doing jetting and plug chops. She's close enough to dial in at Haspin now, so jetting is good. I'm sure my neighbors are relieved that jetting is completed. Over the last two days I've literally seen two separate neighbors wrangle their kids and dogs and herd them into the house before their ear drums shattered. This thing is really, really loud. Our long awaited clutch hub is slated to arrive today so I know what I'm doing after work today. Also, if anyone knows who sells Loctite by the gallon I'd appreciate that.

So how did it go?

[fabiodriven]

Hey! Thanks for asking!

At this time the bike is complete and it runs really well! It has exceded all of my expectations having been built in such a short time.

When I first started jetting, the round slide 40mm Keihin had a 188 main in it. After the rebuild and with the pipe we'd put on I figured it would want more fuel, not only that but you always start fat with jetting, so I bumped it to a 205 first. By the way, there's a generous amount of room to work on this bike. You can swap a jet most likely easier than a factory 250R.

So the 205 was way too fat. I worked my way down in .005 increments until I got it running good here in Massachusetts and I believe that was at 175. I wanted to step the pilot down but didn't have the correct jet available to do so. I got it good enough to load up and was going to continue jetting at Trikefest in Indiana.

I also had my 20" tires on the rear to be a bit more forgiving so I could ride and jet and get used to the bike without it shooting right out from under me. I worked my way down to 172 then 170 and with both of those jets it was burning the rear tires right through fourth gear and across the finish line on the strip. Also with those two jet sizes it sounded like it was running fine to me, however the peanut gallery was insisting it was still breaking up on top. As I swapped in the 165 (I skipped the 168) I also swapped on my drag wheels with the Four-Snows. At first I ran them in the less aggressive direction. I was amazed that it spun those tires right through fourth gear and across the finish line as well. I brought it back to the trailer to go down from a 13T to a 12T on the front sprocket, rear is 42 I think. This sprocket change was not going to help with traction, but I was aiming to be winding out 4th at the big end. I figured spinning the Four-Snows around to the aggressive side would handle the traction issue, I was betting on it. Also at this time I used a rachet strap to lower the rear and sucked the forks up in the triples to drop the front.

On race day they groomed and watered the track and traction was no longer an issue, but then came the wheelies! I'll take wheelies any day. In my first race it wheelied really big but pulled hard, and we barely lost to Cori Shively on her ATC500R. She's very seasoned as well so that was by no means a bad race. It was really close.

In my second race, I was lined up next to race and the two going before us were at the line waiting to go. They were having technical difficulties with the Christmas tree and attempting to fix it, all the while you have finicky open class bikes lined up, running, and getting hot and grumpy. Finally after what seemed like forever they launched the two in front of me. Myself and an XR600 conversion lined up and staged. This race should have been in the bag for me. Just then, a good willed and excited friend approached me from the rear yelling and screaming. I could feel his presence and after the problems they were just having with the tree I figured it was messed up again. I looked over my shoulder and as I did the lights went green. The race was lost right then. Upon my return to the launch pad I asked if I could run again, I wasn't really happy with how that had all transpired, but I was told no I couldn't. At that time I had been outside in the hot sun all day and watched every single race of every single competitor prior to mine. All I wanted to do was plop my arse in the river, so I left the track and that's what I did. I didn't find out until after that I still could have competed for third place. They are very clear on the rules and how the whole thing works ahead of time, but when I get in that situation on the bike I forget everything they just said. It's all clear as a bell ahead of time, but the excitement and the suspense get the better of me once we get going. I'd have loved to have run again but it just didn't happen.

Overall I'm in love with the bike. It runs absolutely fantastic and I'm able to start it quite well now. I'd never be able to start this engine in a bike frame, the trike is the only reason I can get this engine to kick over. It's worth having an in-frame pipe made for it so I can ride it like a regular bike and that's something I'd really like to do when I get the money. So all in all, it's a great bike!!

Awesome! I love it when a plan comes together! Nice work guys!

[cr480r]

Thanks for the update and videos. Very nice for those of us that coundnt be there. Very nice bike!!

[El Camexican]

Having heard that thing firsthand and up close I can tell you it sounds awesome! The events that led to the drag race loss were regrettable I wish they would've let them run again as the 480 was much faster and even came close to winning after starting the run two seconds after the other trike had a launched.

[RIDE-RED 250r]

man that thing honks!!

Hammer down!

They said it was double elimination so I don't think you could have raced for 3rd.
