midlifecrisis Posted April 23, 2010 Report Share Posted April 23, 2010 As some of you know, I have been building a new motor from the crank up since february. I have done a vitos crank, wiseco pistons, MS trail port, vitos hemi head with 20 cc domes and some other small stuff. Im at 270' above sea level. Yesterday I got her all done, mixed up 91 octane at 16:1 (blue marble premix) as per the clymer manual for initial break in. Once their was fuel in it and I kicked it over a few times, I came to realize that there was no fuel getting to the carbs. I checked the overflows at the botton of the bowls, and there was fuel there as well. I decided to see if it woulkd fire, so I took off the airbox and squirted about 10-20ml of fuel in each carb and tried again. It fired up first kick, and I was about as happy as I could have been. It idled for five to ten seconds, then sorta coughed and shut off. I thought it was out of gas, so I squirted a bit more in so that I could screw around with the idle a bit, thrn tried to turn it over. Thats when my worst fear became reality, as the kicker had locked up. I did everything by the manual, and I cant figure out what I might have done wrong? I didnt think taking the airbox off for 20 seconds would lean it out? I never touched the throttle, it only idled! Any help would be great, Im also considering offers! LOL!

baker Posted April 23, 2010 Report Share Posted April 23, 2010 i would never put any gas in the back of the carbs to get it running, if it aint getting gas fuck with it and figure out why instead of wrecking a new motor, carbs are easy and take alot less time to fiddle with than a whole new motor that took two months to build for some reason. i just rebuilt one of my shees in under 3 hours i was riding again, including pulling the motor put in new crank and top end and put it all back in, why 2 months? i could understand if ya had to save the cash for the parts.... i just had alot of extras layin around the shop,lol. sorry bout your luck bro all ya can do is do it again but dont throat feed the carbs oh with 20cc domes whats your compression? i would think you would need higher octane than 91, and 16:1 dont sound right either Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted April 23, 2010 Report Share Posted April 23, 2010 Start by pulling the clutch cover and looking for anything astray. Snap ring for kicker idler gear, etc. Also check stator cover area, loose flywheel, backed out screw on stator. Quote Link to comment Share on other sites More sharing options...
Coupelx Posted April 23, 2010 Report Share Posted April 23, 2010 was the gas you squirted in the carbs premixed? if not, heres your sign. time for another top end and maybe some bearings. Quote Link to comment Share on other sites More sharing options...
gman1320 Posted April 23, 2010 Report Share Posted April 23, 2010 Its just the kicker gear locked up. Pull the clutch cover and free it up. no worries Quote Link to comment Share on other sites More sharing options...
Cali Posted April 23, 2010 Report Share Posted April 23, 2010 Its just the kicker gear locked up. Pull the clutch cover and free it up. no worries Ya I agree.I cant see no reason for it to lock up from giving it a shot of fuel.Uless there was no premix like coupelx said.

locogato11283 Posted April 23, 2010 Report Share Posted April 23, 2010 we need more info. this story doesnt make sense. so you decided that since the carbs werent getting fuel to spray fuel in? how long did you think it was going to run like that? was that fuel premix? why didnt you figure out why the carbs werent getting gas? are you sure the top end is locked up? how do you know that the kicker is just not stuck?

TexasBansheeMan Posted April 23, 2010 Report Share Posted April 23, 2010 (edited) i would never put any gas in the back of the carbs to get it running, if it aint getting gas fuck with it and figure out why instead of wrecking a new motor, carbs are easy and take alot less time to fiddle with than a whole new motor that took two months to build for some reason. i just rebuilt one of my shees in under 3 hours i was riding again, including pulling the motor put in new crank and top end and put it all back in, why 2 months? i could understand if ya had to save the cash for the parts.... i just had alot of extras layin around the shop,lol. sorry bout your luck bro all ya can do is do it again but dont throat feed the carbs oh with 20cc domes whats your compression? i would think you would need higher octane than 91, and 16:1 dont sound right either Not to bust your balls BUT BULL SHIT!! The case mate has to sit for 24hrs to cure. So how were you riding in 3 hrs? to the OP, did you put everything back in right, pull the clutch cover and see if maybe your nut on the clutch basket came loose, or maybe the nut on the crank itself. Hope like piss its not internal, look external before you split it again. Also did you do a leak down test before you started?

midlifecrisis Posted April 23, 2010 Author Report Share Posted April 23, 2010 Just a quick answer here, I mixed the fuel at 16:1 like the manual said before I squirted it in the carbs. It said to do that in the Haynes manual for initial break in. I did it just to see if the bike was going to fire, as I bought it in February and hadnt even heard it run yet! It took me this long because it is my first tear down, and I was taking my time doing it. Also I had to wait for parts to come in, vitos crank bearings took over 3 weeks to get. Ijust wanted to herar it run, thats all. It only rabn for a few seconds, and thats when this happened. Im not sure that the kicker isnt just stuck, thats actually why I came on here to ask, because I covered everything in the manual. I removed the overflow screwat the bottom of the float bowls, and there was fuel there, so Im still not sure why its starving for fuel. Fuel lines are clean, new jets, crossover tube hooked up, and new petcock. Quote Link to comment Share on other sites More sharing options...

The parts are the issue for me. I have to wait longer than normal for them as they cross the border, and the govt takes their slice. I did have the kicker get stuck down as I kicked it over one of the times, but I thought nothing of it, as it released easily. Do you guys think that this has had something to do with it? Im taking it apart over the weekend. Quote Link to comment Share on other sites More sharing options...
