Robocop1051 Posted April 28, 2014 Report Share Posted April 28, 2014 I believe I saw some unicycle action there. We're you in full pucker mode? Quote Link to comment Share on other sites More sharing options...
98Z5V Posted April 28, 2014 Author Report Share Posted April 28, 2014 I was up on the tank most of the time - had no idea how these tires were gonna be, no clue. Didn't know if they'd grip and send me on my back, or be so old and hard that they'd just burn out and get no traction. The hazards of used tires. I really want 17" wheels for this bastard, and real sportbike tires. I'd like to get them out more and get more time on it, but I don't know if the local PD will be listening for the magic sound of 2-stroke now... <lmao> Quote Link to comment Share on other sites More sharing options...
texas30cal Posted April 28, 2014 Report Share Posted April 28, 2014 17" wheels, sticky tires and a big ass front brake conversion! Quote Link to comment Share on other sites More sharing options...
Toolndie7 Posted April 28, 2014 Report Share Posted April 28, 2014 That looks like fun. That thing must stick like velcro. This made me spill a lil coffee though <lmao> I think I tried this... I think my gut got in the way though. All I got was a horrible kink in my neck. Then I fell off the couch and hit my head on the coffee table, knocking myself out cold. Really hard to explain to the screaming maid when she finds you buck naked, covered in vegetable oil, with your belt wrapped around your neck...

shibiwan Posted April 28, 2014 Report Share Posted April 28, 2014 (edited) I was honestly waiting for you to go splat! If anything for the entertainment factor. <thumbsup> <thumbsup> Edited April 28, 2014 by shibiwan Quote Link to comment Share on other sites More sharing options...
seasprite Posted April 28, 2014 Report Share Posted April 28, 2014 Looks like a you had good time. How fast do you think that bike will go on pavement? Quote Link to comment Share on other sites More sharing options...
98Z5V Posted April 29, 2014 Author Report Share Posted April 29, 2014 High 80s easily, if I can find a stretch just a little bit longer than what I was on. And it gets there right now. One way I can find out is to take it to the old shop I worked at and strap it down on the dyno. The bonus is getting a Hp and Tq graph on it.

seasprite Posted April 29, 2014 Report Share Posted April 29, 2014 Do it, it would be interesting to see the how much torque that 2 cycle puts out <thumbsup> looked like you had some fun trying to manage it. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted April 29, 2014 Author Report Share Posted April 29, 2014 Should be more than a stock bike, which was right around 60hp. I need to see what it does, anyway. I need more jets, before I start, so I can run the jetting up and see how it does. Screwy thing about a dyno, and tuning a 2-stroke - you don't tune based on A/fr. The smoke in a 2-stroke will screw up and air/fuel ratio monitor pretty bad. You just have to tune to the jetting changes. Run it, check numbers, change a jet and run it again against the numbers. You'll only be able to change one jet at a time and watch progress, until it starts coming back down again. Then you know where the power mark was and what jet that was. I always tune a 2-stroke with 15% brake on the drum, to simulate the load on the engine in sand. Here's what I did on my first-overbore (66.25mm piston) on the 250 2-stroke quad: Here was the tuning I did on the M109, after pulling the secondary throttle plates - Initially, with the secondaries out, when you'd mash it, it would shoot to over 18:1 A/fr. Not good. Tuned it in to pull a consistant 12.75:1 A/fr, just going a little lean at redline... I really like that bike - over 100 lb/ft of torque from 2,250 RPM all the way to redline... >:D :hethan: Quote Link to comment Share on other sites More sharing options...
shepp Posted April 29, 2014 Report Share Posted April 29, 2014 You can get gps apps that will show speed on your smart phone my buddy uses that in his pro streets car on cruises Quote Link to comment Share on other sites More sharing options...
