Can't pull 6th gear


The Noob

Recommended Posts

First post.

Was at Glamis and couldn't pull 6th gear on flat ground. Talked to other banshee owners in my group with similar mods and they report same problem.

Question is; is this normal or abnormal for lightly modded banshee ?

 

13/ 41, Sand skate, Fatties, K&N, no lid, Boyesen reeds, Yamalube 32:1 50/50 110,

290-25 Toomey needle 4th position

126 compression , not performed leak down.

Had bike dyno tuned at Alba when purchased from friend With 330main 30 pilot ...146hp. Been dicking with jetting ever since because still cant get crisp response at takeoff or pull 6th gear.

Any response or input much appreciated. .

Ditch the 110, you dont have enuff compression to even go 50/50 on that. thats probably 90% of your problem, fill it up with some fresh 91 or 93 32 or 40;1........do a plug chop. Most likely need a needle clip change.

 

Ps if you get to messin with it.....remember a bog is lean and a pop or popping is rich. small adjustments.

You have lean and rich bogs. A lot of times you will hear a lean pop.

The jetting I have in their now is Toomey specs even though I have FMF pipes, I talked to Toomey customer service and this was there recommendation- 290 main 25pilot Toomey needle 4th clip. It ran a bit better with 330, 30, stock needle in 4th clip @ 40:1. Gonna change to 300main 30pilot Pro design foam with lid on..My friends Banshee with T6 and foam filter with lid on ( unsure of jetting) and Tors on, is the only bike in our group that's crisp from takeoff and can pull all gears no problem. The guy he bought it from ( another friend)  swears its stock besides the Toomey's and pro design foam filter.

The question is still out there; why cant I pull 6th gear on sand highway ? is it strictly jetting (fat or lean) or is a relatively stock banshee not capable of pulling sixth gear.

Thanks so much.

Yeah I saw that and tried the 260 when trying to get it crisper, didn't help. I used the jetting spec sheet on this site and came up with 30-300.

Had the K&N w/no lid and the worksheet said 340 main ? But I've seen EVERY jetting recommendation on EVERY forum and most everybody says 290-310.. 27.5 or 30 with my setup and sea level.

Pilot jet is on the low end of the circuit, how would going up to 30 help with 6th gear bog ?

Go to a 300 main with a 30 pilot and a STOCK needle. I'm not a fan of toomey needles. Leave the lid of. Try this. This should get you real close. Probably end up with a 280 or 290 main. Back the 30 pilot out 1.5 turns.

 

Also move stock needle back to middle clip

Went with the setting 300 main, 27.5 pilot, Toomey needle 4th clip, Proline Foam-no lid, and back to 14-41 gearing. Still not responsive off idle and trouble pulling sixth, but better !

Switched to stock needle & bammo.

I tried every conceivable setup to get those Toomey needles right ( I paid $50 for them & really wanted them to work) but just couldn't get them to work with my relatively stock setup.

This is the SECOND time I've tried aftermarket needles with poor results.

Stick with stock needles if you run stock carbs !!

What needle settings, and elevation are you at?
