hey guys, I have a 2002 M2 and it won't start up. Heres the story: I went away on business for 4 months and in the mean time a friend was supposed to ride my bike a few times while i was gone. well...that i guess that didnt happen bc now it wont start up. I thought it was bad gas so I refilled the tank with some premium and gave it a crank...NO DICE  The bike is trying to start but it just won't fire to turn over. I just replaced the starter clutch ...so i know thats all good. i'm not much of a troubleshooter but the next step is changing spark plugs (i guess) to see if that helps. My pops says it may have gunked up the jets in the carbs but he knows very little about motorcycles (however dad's do tend to always be right) any suggestions? im itchin for that low vroom-vroom sound that you can only get from a buell PLEASE HELP. thanks, biggsammy13 austin | ||

Dad is most likely correct,gunk in the carb. | ||
| Biggsammy13 |
Is there a way to clean out the carb without a disassembling the carb from the bike? Thanks! | ||
| Jramsey |
Best to remove and disassemble and flush all the circuits with spray carb cleaner. | ||

Nope. Bite the bullet and pull it out, carefully take it apart on a clean bench (at least the bowl area), and clean every last crevice as if you were going to eat off it. Avoid metal for cleaning. My favorite tool is bamboo shishkabob sticks from the grocery store. Tough as can be, you can wear out the tip and sharpen them down to another tip, carve them into a point or cut them with a pair of wire cutters and get more of a scraper. That and carb cleaner. The cleaner is hard on rubber, so try and keep it on just the metal bits. Fine wire helps to clear out jets and narrow ports, but the Bamboo will do most of what you need without as much risk of hurting anything. It'll let you get the cap for the air fuel screw out of there as well, and adjust that for better running cold. Your main jet is probably right, but your pilot jet is probably too lean (unless somebody else has been in there). The "quick fixes" don't work... that gas turned to varnish. | ||

Also, since you already have the carb off, replace the intake seals, they are shot. Try a 190 main and a 45 pilot with the screw out 2 1/2 turns. Brad | ||

I hate to say it but my bikes sit thru the winter without many starts on them, and I haven't had that issue. Could be differences in the fuel from my area to yours. Have you pulled the plugs to look at them, I would do that before pulling the carb off. | ||
| Blks1l |
Actually I see we are almost neighbors, so our fuels would be mixed the same. | ||
| Biggsammy13 |
I'll check the plugs first. If not that then I'll be bamboo'n it with the carbs. Thanks for the tips Guys. I'll keep u posted on the results. | ||

I've had this happen to my 2001 M2 twice. The first time I try to start it in the spring there's no fuel. Both times it has turned out to be the float needle stuck on the seat. I was able to clean it w/o removing the carb. | ||

PROBLEM RESOLVED - Just took some carb cleaner and sprayed it directly into the intake (took the forcewinder filter off first) and BINGO!!! BIKE STARTED RIGHT UP. let it run for 20 mins and have been riding it nonstop. Thanks for the help guys ...much appreciated. | ||

Bigg, Make sure you run a bunch of Seafoam through your fuel system. This will help remove any gunk in the carb internals. Put a couple of oz in each tank full of gas for a while. It really helps. Still think you should check your intake seals... If they have not been changed I can guarantee they are bad. Brad | ||
| Blks1l |
I hear several people here regularly say the intake seals should be changed every year or so, but mine have been in my S1 since at least 2000 when I got it, and I don't have any issues with it. | ||

I'm pretty sure my seals are also original since 2000. Got almost 17K miles. No leaks whatsoever. Knock the wood... | ||

Sorry to be late!But I think your Idle was too slow.I always run Idle slow when warm and if you let bike stand for along time it won,t start even using choke.So when starting after long storage run idle way up and choke then set to normal after running.using idle extension on cab or thought-body.I learned this a long time ago on kick-start bikes.Butch  |
