Just pulled the carbs on my banshee

[350Xhilaration]

I got this banshee over the fourth. It has FMF gnarly pipes with turbine core II spark arrestors and a twin air filter with lid and snorkel. I pulled the seat off the other night and found some paperwork. There was a manual, some FMF stickers and two main jets in a plastic bag along with some FMF paperwork. The paperwork said to use the provided 260 main jets when installing the pipes to get close and then you can fine tune it. Well, since the 260s were in the bag, I wanted to know what were in the carbs. I havent had a chance to run this thing yet wide open to see if it breaks up, bogs, etc. I had about 30 minutes of free time tonight so I pulled the left carb off. took 9 minutes. (I thought you guys said these were a pain in the ass to remove) Anyway, it had a 200 main jet in it. I put the 260 in and pulled the right carb off and replaced the 200 with a 260 and reinstalled both carbs. That killed my 30 minutes and I havent started it yet.

 

Banshee is all stock except for the pipes and silencers. I'm thinking it was too lean the way it was. Especially after reading about how most people run 300 + mains in their modded banshees. Any experience with main jet recommendations to start at before doing a chop? Kinda like boresighting a new scope on a rifle. Get it close and then start tuning.

 

Thanks

you did exactly what you should have done.its a good thing you went rooting around,before you roasted your top end.with that 260,after a plug chop seams a lil rich pull your lid off.but i would put some new plugs in her before you go and chop them plugs.im over in jersey and with my old school fmf's i was running a 270 main with my lid off,with a uni filter and rad valves and cool head.so that 260 should do ya

I'd have been a lil torqued off. I'm taking it riding this weekend with some guys that are coming in from out of state for Quadfest and didnt want to roach my new banshee. I may run it with the 260s for now (since I dont have any other mains accumulated yet) even if I do have to run the lid and snorkel til I get some bigger mains.

 

Thanks for the quick response.
