BigRed350x Posted December 21, 2006 Report Share Posted December 21, 2006 Alright, took it out to the dunes today to play around a little bit. First off, let me say... HOLY SHIT! That thing is retardedly fast. I love it! Not much at all down low but the upper mid-range and top end are ridiculous. This thing feels like it hits harder than ol blue did for sure. Ran great all day long. Played around with the jetting a little bit when I first got there and had it pretty well dialed in. Was running as good as I was going to get it with the needle and jets I had with me. I know I was still rich because it would sputter up on top. Other than that it felt great. Put a new clutch in it too! Second run up our big drag racing hill I realized I definitely need a lockup clutch setup for this thing. Took off hard in 2nd gear and when I grabbed 3rd and got back into the throttle you could feel it slipping a little. I definitely need WAY more than 9 paddles too! Thing doesn't hook up and go until 4th gear. I was running back and forth across a flat spot and was spinning around screwing off then took off in a straight line again. I missed a shift between 3rd and 4th gear and it revved up pretty high, then I got it into 4th and went to get back on the throttle and it fell flat on its face. Made a WONDERFUL little clank clank sound then died. I let it sit for a few min then kicked it over and it fired back up so I limped it back over to the truck about 400yds away. Pulled my plugs to see what they looked like... Left cylinder looked PERFECT, right cylinder not so much. Had aluminum deposits all over the plug, some nice gray shit all over the plug and the eletrode was smashed closed. Ha Ha Ha! Loaded it up into the truck and wen to the shop. Tore the top end apart to see what let loose... Looks like the skirt shattered and caused the mayhem. Trashed a dome, total loss on the piston and wristpin bearing. Cylinder however showed pretty much no damage. Had some aluminum on the walls and a few litlte scratches, other than that no damage. I'm so glad I work in a machine shop! Took the dome over to one of the small lathes we have and spun about .001" off of it and it cleaned up pretty good. I don't have a problem running the dome in the condition it was in after I turned it, so that was good. I ran our diamond hone through the cylinder and cleaned it all up. Just have to order an o-ring kit for the head, new piston for the right side and I'm good to go. Here's what I think happened... it was only 15 Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted December 21, 2006 Author Report Share Posted December 21, 2006 Cylinder Piston. Think I can just re-ring it and be ok? I think so. Here's after cleaning out the crank trench and stuff. Dome Before. Dome After. Cylinder after hone. All this happened today between 1pm and 6pm. I just got home from the shop after honing and turning the dome. All in all not a bad disaster. Easy to fix and cheap. Really wish I knew what actually happened. Bike ran great for over 3 hours before it just let loose. You can see by the other cylinder that it was running pretty good. I don't think it was an issue with jetting with the methanol I think it was something else that let loose. Who knows... guess I have to put it back together and go back out and try it again! Ha Ha!! I am putting together some video clips I got of me and rick riding it today and I will put it up in the video section when its done. Should be up later tonight. If anyone things my shit doesn't break just like anyone elses, here's the proof otherwise! ROFL! - Jared Quote Link to comment Share on other sites More sharing options...

Thanks! Ha Ha Ha Ha! Good one! I'm compiling video right now, check out the video section here in like a half hour and video of it will be up! - Jared Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted December 21, 2006 Report Share Posted December 21, 2006 damn that sucks...at least youre able to fix it all yourself..that would end up costing most people a lot more than that!! Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted December 21, 2006 Author Report Share Posted December 21, 2006 damn that sucks...at least youre able to fix it all yourself..that would end up costing most people a lot more than that!! Yeah... $25 for the o-ring kit for the head (which I don't reallyneed, but would like to have anyway) Figure $75-80 for the piston and junk. Ended up being around a $100 Ooops! I am really glad that I can do most of my own work on my stuff for sure. Working in a machine shop where I have access to the stuff I need is priceless. That dome would have sucked balls, as well as getting the cylinder honed if I didn't work here. Quote Link to comment Share on other sites More sharing options...

bansheeseat$$ Posted December 21, 2006 Report Share Posted December 21, 2006 Jared, Thats to bad but like you said atleast you work in a machine shop.I watched the vid of it and it sounded like it was lean seizing on the last one that you had mentioned it didn't qiute sound right.alky does some wierd shit when its that cold outside.I like it with the 06 plastic on it way better. :beer: Quote Link to comment Share on other sites More sharing options...

Not that big of a deal really. Simple fix, just put me out of commission on this bike for a couple days until I can get parts. Guess I will just try it again and see what happens. Might throw my .125 main in and richen up the needle a clip or two and see what happens. LOL - Jared Quote Link to comment Share on other sites More sharing options...
majicmike Posted December 21, 2006 Report Share Posted December 21, 2006 (edited) 2 things that i can see is that you said it stuttered on top that is lean IMO judging buy the good plug and it was lean. lean revs hard but falls off on top (Not enough fuel to keep reving) rich bogs on the low end and pulls like mad up top ( to much fuel to rev ) The guy that built that motor ports the windows of the pistons when it over reved it broke the skirt. So IMO the detonation weaked the piston and the over rev did it in. I would replace both pistons so you have 2 strong pistons IMO or port the new piston but Im not a big fan of that just incase of the accidental over rev. Also on cold days I would run race gas i would make life easyer IMO. Did you check the needle jet tube? what was it drilled at?

That's what's werid... it would bog real bad down low then got up on top and kept pulling and pulling... then when if felt like it was up above the pipe and the power was dropping off it would sputter. Probably lean like you said, but didn't feel lean. Maybe I'm just not used to methanol. I didn't know the windows were ported. If I knew that I would have pulled those pistons and replaced them with new ones. Never liked having ported windows, makes the skirts weak and the tend to break just like that one did. LOL Needle Jet Tube was at .118. I'm going to drill it out to .125 tomarrow at work. Maybe .120 Dunno yet. Have to look at it more and make a decision. I guess riding it in the temps I was in probably wasn't the best of ideas, but I couldn't have that thing sitting in the garage any more! Ha Ha! I'm not at all upset about it, I have to expect stuff like this with a new bike and a new fuel to me. Just replace parts and try again! Ha Ha! Suppose I better get both pistons then and just keep that good one for a spare. I bet if it had been warmer it probably would have been better to be playing with jetting. But I ride in this kinda stuff so I have to get used to jetting in it. Mike, what do you suggest for getting rid of the bog and still staying fat on top? Drop the pilot a size? Lean out the needle a clip? I'm thinking I will go up a size on the main, leave the needle where it is, maybe drop the pilots a size and start with the powerjets all the way out again. Oh yeah, I also need to get different needles from you too! - Jared Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted December 21, 2006 Author Report Share Posted December 21, 2006 It just didn't fee like a lean sputter to me. Just seat of the pants it felt like it was really rich. Does methanol feel different when its rich compared to race gas? Had a lot of people tell me I was going to be more than rich enough with what I had in there right now. LOL Guess no one was intending that I was going to go out and ride it in 15 Quote Link to comment Share on other sites More sharing options...
