FireHead Posted December 2, 2004 Author Report Posted December 2, 2004 I'm still not sure. My Calgas showed up yesterday, but it turns out that the damn Sun machine has a bad oxygen sensor. So now I have to wait on Equiserv to come out and fool with the thing. I did have time to get finshed putting the pipes on last night. Maybe this weekend I can take a shot at jetting the bike like everyone else has to. Quote
FireHead Posted December 8, 2004 Author Report Posted December 8, 2004 Ok, so I got it to start with a 27.5 pilot and 360 mains. Once the bike is running, on the transition from 1/8 to full throttle there seems to be a slight bog in bewtween. Is this a needle clip adjustment? Man I feel like a retard with out my exhaust gas analyzer. Quote

I never ran higher than 25s on mine, but I don't have nearly as much done as you. If that doesn't help, it has to be your needles. Just try going one clip richer, see if helps. If not, go one clip leaner. Quote
Banchetta Posted December 10, 2004 Report Posted December 10, 2004 Hesitation is caused by leaness, Raise the needle by lowering the clip. Move the clip towards the point of the needle. You should see decent gains. You have to disconncect the slides off the cable by pulling back the spring and shaking the gold clip out, then unscrew the two philip screws and the needle will come out. Pain in the ass at first, but you can get prettyfast at it after a while. Quote
FireHead Posted December 10, 2004 Author Report Posted December 10, 2004 Ok, I moved one clip down and that fixed that problem. I am still having the cold start issue. I cannot get the bike to start at all with 30 pilots. The 27.5 pilots I can get the bike to start with, but I can't seem to nail down a position of the air screws to make it start consistantly. In fact no matter what I do I have to kick the crap out of it. My exhaust analyzer is now up and running and I know I need to be in the three turn and under ball park according to my A/F ratio at idle. Is there anything else that I am missing here or do I have to keep fooling with it? Quote
FireHead Posted December 11, 2004 Author Report Posted December 11, 2004 It has been suggested over on Planet Sand that I move up to a 32 pilot jet. Is this a good idea? Does anyone have any other ideas? Quote
FIRST BANSHEE Posted December 11, 2004 Report Posted December 11, 2004 It has been suggested over on Planet Sand that I move up to a 32 pilot jet. Is this a good idea? Does anyone have any other ideas? 291902[/snapback] if it starts on a 27.5 but not on the 30 a 32 will be worse...have you check the condition of your reeds? chip, cracked,or open reeds will moke it hard to start cold.

Banchetta Posted December 11, 2004 Report Posted December 11, 2004 Did you check to see if the bowls of the carbs have been switched yet? Also make sure the slides are in the right carbs. Cutaway should face the air box. Quote
batoutofshell Posted December 12, 2004 Report Posted December 12, 2004 I picked up a new Banshee a couple days ago and it will not cold start without starting fluid. Everything is mechanically sound on the bike, but I'm not sure about the carbs. I normally would use my exhasut gas analyzer to jet them, but I'm out of CalGas at the moment and it may be a few days out. I'm thinking I might need bigger pilot jets, but this bike shouldn't have enough done for it to need larger than stock pilots. It has 310 mains. Someone please tell me what I need to do or what I am doing wrong. 282515[/snapback] Just wanted to let ypu know I had the same problem and have been trying to figure it out for a while now and found my carb bowls were switched i fixed it and it starts on the first kick again!!!! :headbang:LET US RIDE FREE!!!!

FireHead Posted December 12, 2004 Author Report Posted December 12, 2004 (edited) Did you check to see if the bowls of the carbs have been switched yet? Also make sure the slides are in the right carbs. Cutaway should face the air box. 291962[/snapback] The bowls are on the correct sides and the reeds are in relatively perfect condition. The starting on the 27.5's and not the 30's was probably related to not reconnecting the choke cross-over tube after checking the bowls. Currently the 30's are much better,but it still will not cold start. I am leary of installing the 32.5 pilots, it has also been suggested that my choke may not be working correctly. Has anyone had any experience with this? The choke seems to have some effect when the motor is actually running. I am about ready to build another motor for this thing if I can't get this one running. Edited December 12, 2004 by FireHead Quote

FireHead Posted December 17, 2004 Author Report Posted December 17, 2004 Did you check the cutaway in the slides to see if they face the right direction? 294138[/snapback] The slides are in properly. You have to remember that this thing runs properly if you use starting fluid. According yo my exhaust gas analyzer, I have everything set about right (13.5 A/F), except it doesn't want to read accurately at idle. My guess is that I need 32.5 or 35 pilot jets (the jet sizes that aren't available locally). I honestly do not think that there is enough done to the motor to require it. The other thing that I can think of is that I may need to drill out the choke jet a tiny bit. Quote
FireHead Posted December 27, 2004 Author Report Posted December 27, 2004 The damn thing still does not cold start even with the 35 pilots in it, but once its warm it starts on the first kick every time. I changed the domes in the head out so now I have about 190 psi across both cylinders. Would getting a larger jet to replace the jet in the choke circuit be a good idea? I am basically out of ideas.

Banchetta Posted December 28, 2004 Report Posted December 28, 2004 Starts great when warm indicates that its the choke. did you blow compressed air into the carb bowl jets? Tube? something must be clogged.............................................................................................................still thinking..................................................................................................................................................................................................................................................I'd look into the choke circuit area. Do you know someone w/ another set of carbs? Or at least the choke carb... Quote

I will have to find somebody who has an extra set of carbs. I may just buy another set. If I were to buy another set what would you recommend? Quote
