Take a mic or calipers and you want the total of the two washers not to exceed 0.05. EZ | ||
| Gearheaderiko |
You can go with more than 0.05 (or less) if you're actually tuning your carb. 0.05 is a general recommendation. | ||
| Ezblast |
Actually with the twins - .01 is closer to where you want to be, with the single .05 is better. EZ | ||

Hi folks, we're new to this forum but glad we found it, seems like lots of cool people here. We are located in Santa Clarita Ca. and have been following the recent SLO ride. It looks like you all had a great adventure, maybe we can tag along next time. Here's the issue, my son's 2001 Blast runs pretty well except for the motor cuts out when ridden at freeway speeds. He says that any modulation of the throttle will cause it to backfire, then it stumbles until he down shifts, then it will catch and run again. It sounds to me like fuel starvation, or maybe the coil is shorting. I also suspect that the fuel/air mixture screw is not adjusted correctly as it smokes a bit at lower RPM's. We need to get a factory manual so that we can properly maintain the bike, but in the meantime, any advice you might offer would be appreciated. Best regards, Grant. | ||

G PMed you EZ | ||

LOL, now I know I'm not the only one who put in #6 washers as shims. Now I just don't know if I wanna risk putting in the correct #4 washers and screw things up again. (Erik knows what I mean) | ||
| Garlic_sauce |
Yeah I did that too, Had 2 #6's in there. Funny thing is I didn't noticed how bad the hesitation was until I put in the K&N filter and Denso iridium racing plug in. I went to "the nutty company" got two brass #4's(small OD) and now the bike screams through every gear without that hesitation.  | ||

Welcome Grant! I dont know what EZ pm'd you but, first question: Is the California EPA Charcoal canister still hooked up? If it is then disconnect it. Otherwise any future help is pointless. The canister is the #1 cause of problems on CA Blasts. After that, it sounds like ignition module problems,but.... | ||

I used #6 washers and had to cut down the O.D. a bit to get them to seat properly...if you are not careful with the O.D. the needle will ride high.. | ||
| Ezblast |
Mine where hobbies't machined #6 Brass washers(says it on the package) - a totally specified piece you can find at those stores that sell mechanically working train sets, etc. - It was fun finding the store, but I went in and asked, and he pointed me to this wrack of miniature nuts and bolts, I was checking out the brass section and the 6 and 4 where both there - bought both - chose the six because it was closer to .05 and because it fit - other folks using regular stamped washers are to be warned to check and modify your washers as necessary.

I have been noticing a leak around the seal of the cover of my airbox, especially when i give it a lot of throttle while riding or i am on the highway for long periods of time. It smells like fuel and i was wondering what causes this and what would get rid of this or help to alleviate the situation. | ||
| Ezblast |
EPA - the leaking is oil from the spigot, the smell of gas is a reversion that happens on stockers - no worry there. EZ | ||
| Thumper62 |
So, what do i need to do to correct, or stop this from happening, and why is it happening? Thanks EZ | ||

Hey guys, I purchased my 01 Blast about 3 weeks ago. When i got it, there was already a White Brothers Exhaust on the bike. How do i know if the carb has been rejetted and can someone give me directions as to how to do this without screwing anything up?? Also, is it acceptable to keep the exhaust on it, or should i get a different one? Is there any other quick modifications that I could do to get quick performance gains. The bike has a little over 7k miles on it, any maintenance issues i should be concerned with. Sorry its so many questions but i know i am in the right place for the answers. Thanks all. | ||
| Ezblast |
Its probably jetted ok if it isn't popcorning at the exhaust. 24 discs would maximize the performance, shim the needle .05, if its not leaking oil, then the rockercover gasket has already been done. EZ | ||
| Johnnymac |
EZ, I have popcorning on mine when decelerating with a closed throttle. No backfiring, just a nice burbling popcorning. I have the Ram-Flo intake and modified stock exhaust and the carb is jetted 45/175 and shimmed. Is this a sign of too lean a mixture? From everything I've read it shouldn't be with the very mild mods I've done. Should I take the slow jet to a 48? Johnny (Message edited by JohnnyMac on June 01, 2009) | ||

You should be able to tune that out with the air screw. EZ | ||
| Thumper62 |
EZ, I am actually a young and new rider with very little knowledge of my bike, however, the gasket has been redone, but i have no clue how to shim the needle or what 24 disks are. Also, it is a little more than a burbling i would say, but not necessarily popcorning with no throttle. Thanks for the help | ||
| Ezblast |
If it is a WB exhaust - there will be discs at the end, if tuned right it, and no seriously modified intake, will be jetted at 45/175 and shimmed needle at .05. You get any, just adjust the air screw out a quarter turn. EZ | ||
| Thumper62 |
Also, I have been noticing that leakage of oil problem around the airbox, how and where should i relocate the pcv tubes with a breather on it, and which end, if any, should i do away with, the whole issue is just a little blurry to me, however, i was told that i should get the dern thing out of the airbox to reduce the leakage. | ||
| Johnnymac |
EZ, by "air screw" you mean the idle mixture screw, right? I already have it adjusted at 2.5 turns. If I back it out 1/4 turn at a time until the popping goes away I should be good? But if it take 3 full turns or more then I should up the slow jet to a 48? TIA, Johnny | ||

Anyone see the Custom Intake on fleebay kinda nice but I really like his dasbootenator | ||
| Kenster32 |
actually its real nice i bought the first one he sold the carbon fiber cap looks pretty slick and it seems well made | ||
| Xgecko |
I like my intake more but the boot collar appeals to me I could remove my carb support and it would look a lot better | ||
| Ezblast |
 This one he sells flows the most air, so would be a better choice, The Super das boot rocks! The reason I looked at it is because that intake houses a alum. torque stack that would be more durable, and allow a complete filtration when riding in the dirty city - lol - and switch back to just a filtered stack when jamming down the back roads.

I have issues with my blast! Its a 2000 with 3600 miles.I cannot get it to go above idle. I have replaced auto enrichner, both jets, The deal under the float with a pointed rubber end,das boot,And the plug. I only use premium fuel But, it seems to want to flood out when I give it gas.Any sugestions? | ||
| Ezblast |
Disable the safeties - flip the center diode and cut and twist together the kickstand wires. EZ | ||
| Donaldj |
Where is the center diode located And what does it look like. | ||
| Ezblast |
in your fuse box - the center fuse is a diode - flip it. Has your pulley recall been done - have it done ASAP if the answer is no, it is a free service and important safety wise to do so. See recall section for that. EZ | ||
| Donaldj |
Flipping meaning just pull it Or, turn it around. No I have not had the pully recall done But, I was just reading about it. |
