Spark Plug Removal & Air/Fuel Mixture Screw Adjustment
So............I havebeen unable to ride my Black Cat since taking it out of winter storage. I can't get it to the dealer b/c I have no way of getting there since it doesn't run (and my roadside assistance has expired). I did call and talk to the dealer and he suggested that I take out the spark plug and have a look at it. I can't figure out HOW to get it out - any help would be greatly appreciated.
I'm thinknig the air/fuel mixture screw needs to be adjusted but I don't know HOW to get to that either!!!! When I posted this problem a while ago, someone suggested drilling a hole in the pet carrier for access to it but didn't elaborate or respond to my follow-up questions. So, once again, I ask for help in resolving this problem.
Anyone????

You get to the plug by pulling the cap off, you have to lay down and reach up under the scooter, behind the plastic that is the bottom of the foot area. It's almost below the oil tank. You won't really be able to see it. You do it by feel.
Pull the seat out before you go drilling any holes and look for the little screw for the air/ fuel adjustment.

just a bit of advice if this is anything like the Rattler. I accessed the plug from the bottom of the bike and did not have to remove anything. Most spark plug sockets and ratchets will not fit between bottom cowl and spark plug. Rather than removing the cowl, pulled the rubber plug out, put the socket on the plug and used a open end wrench to turn the socket. The spark plug socket I used had turn-able surfaces(shaped like a bolt) on the top end.
Good luck

...as for removing the seat, I don't have a BC, but the Rattler should be the same. Two brass colored bolts (10 mm) at the top front, two at the bottom rear, two on the top rear and a phillips head screw right in the bottom. Remove those and lift the seat and seat bucket out.

Like Ray & DMW said, it isn't necessary to remove the seat to replace the plug.
It also isn't necessary to remove the seat to set the low speed air screw either, but you do need to know which it is (brass colored slotted screw to the left of the large black idle speed adjustment screw), which way to turn it (out = leaner & in = richer, all other things equal) & use a short flat blade driver to reach it. Supplemental lighting may help you to see it more clearly. You WILL need a correctly sized screwdriver.
If you don't know what it is currently set at, GENTLY screw it all the way in & then back it out 2.5 turns for a baseline, & then adjust as needed from there...

It's the little gold screw right next to the idle adjust(the black knob). It doesn't have a head on it like a normal screw, just a slot for a flat head.

Didn't you get a wrench with your bike that's made to fit up in there? i diddmwarren wrote:just a bit of advice if this is anything like the Rattler.

Yes I did, I just needed to verify the location of the spark plug.Ray Knobs wrote:Didn't you get a wrench with your bike that's made to fit up in there? i diddmwarren wrote:just a bit of advice if this is anything like the Rattler.
