Ned Posted April 27, 2012 Author Share Posted April 27, 2012 I was thinking that, but for the 10 motor version they have to be started via that output shaft so i may as well solve that problem now... Quote Link to comment Share on other sites More sharing options...
sentra Posted April 27, 2012 Share Posted April 27, 2012 yo i was thinking, with the way it used to be setup, could you remove all but two sparkplugs, start it, then slowly bring all the other motors online? Quote Link to comment Share on other sites More sharing options...
Ned Posted April 27, 2012 Author Share Posted April 27, 2012 That was also the plan once i fix the broken shaft, which means i need to do a dump shop run for more motors as i have no more shafts... though i'm not sure how much magnetos like to be spun up without having something to fire into but i don't really care at this point. Was even thinking about tapping some sort of pressure release valve into the head that i could easily enable/disable instead of having to take plugs out and that way they can keep sparking or something Also, the shafts are stupid weak... it just snapped off like it was made of glass when i put the roll pin through Am thinking i may have to just go all out and hope it works....

Brock-Lee Posted April 27, 2012 Share Posted April 27, 2012 Fucklol that roll pin is huge. You drilled away most of the shaft. Cut you roll pin back a bunch of sizes and try it on an already fucked one. Quote Link to comment Share on other sites More sharing options...
Ned Posted April 28, 2012 Author Share Posted April 28, 2012 That was my only spare one. I drilled it out to 3mm from 1.5mm as the bolt i happened to have last night was 3mm and wanted to try that so i got a 3mm roll pin as well this morning.

KIRK Posted April 28, 2012 Share Posted April 28, 2012 genuine anti clockwise engines get around this problem by having left hand threads for stuff that bolts onto the crank. what if you have all the engines facing the normal way and running clockwise with two banks of 5 and use some sort of lay shaft/s to bring all the power into line? or just have all 10 engines inline lol Quote Link to comment Share on other sites More sharing options...
Ned Posted April 28, 2012 Author Share Posted April 28, 2012 The problem is that they will either try to undo when you try to start them, OR they will undo when you try and accelerate. it'll never work I have a pretty great idea though that i'll try and implement this week.... in the mean time i'll just play around with a few other ideas i have for the motor... Still have to sort out fuel and throttle... which isn't hard, but when you're doing 10? p.s. a LOT of people use these Ryobi motors and there is actually a bit of info on them online. They use them as RC plane and boat motors of all things. One dude even claims they have 3.5HP with a little porting and a bigger carb! From what i've read, they are 1.1HP in factory form... so that's 11HP for me Quote Link to comment Share on other sites More sharing options...
KIRK Posted April 28, 2012 Share Posted April 28, 2012 would be easier if you got full crank engines with proper ptos and centrifugal clutches. If they all had clutches you could start them individualy which would make things easy. However if would be quite expensive to find 10 non chinese engines in good cond. why will they undo if they are running clockwise? my panda bikes shaft thing would undo when i applyed the coaster brake until i put some red loctite on the threads. hasn't come off since Quote Link to comment Share on other sites More sharing options...
Ned Posted April 28, 2012 Author Share Posted April 28, 2012 Oh, i agree! I really wish i did have motors with clutches etc. I even looked at getting some from China for cheap and they are only US$21 each but then it's US$200 shipping because it weighs so much haha so quickly put a stop to that idea. So whatever way the motor runs, and whatever way the thread goes, you will put force on it one way trying to start it and the other way when it's running so regardless of what way i run it, if i use a thread, it'll try and undo at some pioint. I put loctite on the shafts of the 10 motor thing and i doubt they are ever going to come off again THB but i still need a better solution that hopes and dreams because if one does decide to come off, it'ss throw the chain and i'll be left ball-less. Theres 3 or 4' of chain on this thing and those motors rev out to 12 000 rpm... Better safe that sorry ets haha Quote Link to comment Share on other sites More sharing options...
xsspeed Posted April 29, 2012 Share Posted April 29, 2012 decide on a scale of 1-10 how much you like your balls and build that into a safety factor of chain strength, lol. 1 Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted April 29, 2012 Share Posted April 29, 2012 yeah i vote lay shaft(s). I think thats the only way this is ever going to work. Quote Link to comment Share on other sites More sharing options...

EURON8 Posted May 6, 2012 Share Posted May 6, 2012 but a no go. Too costly This WILL be finished before bike summit. I don't care how much time/money it takes, but i will finish it! lulz Quote Link to comment Share on other sites More sharing options...
felixx Posted May 6, 2012 Share Posted May 6, 2012 decide on a scale of 1-10 how much you like your balls and build that into a safety factor of chain strength, lol. Then hire it out.. call it "THE VASECTOMIZER Quote Link to comment Share on other sites More sharing options...
