Is this jetting right?


Recommended Posts

Well i gotta 87 banshee with 91 motor in it.

 

Has Bills pipes exhaust, Cool head, uncertain on the size of domes in it, and if the motor has any differnt bore, or polish work done.

 

Just put a pro design timing plate on, an running it +4

 

Running 34mm mikuni flatsides with K&N pods

 

Pilot jet is 25

 

Main jet is 340

 

Bought this bike for 500 bucks. cleaned it up an its running. Havent done any compression test on motor, but after cleaning carbs it fires right up first kick. I just did a plug chop and was wondering what ya'll thought if this was good or bad. Did the plug chop procedure step by step. The plugs to me look a lil on the rich side. Bike runs fine. has a lil bog on 1/4 throttle but once wound up its smooth through all the gears? So if anyone has any suggestions i'm all ears. Kinda new to this two stroke, but definitally addicted. thanks

i'm runnin those carbs with a dune port from HJR and t-5s. i run a 320/330 main and 30 pilot. dyno confimed it to be pretty spot on last weekend, bout 70F and about 1500 ft above sea level. think i might jump to 40 pilots just for starting issues. 25 seems way low. i know most guys run the stock 50 pilot.

I would drop to a 330 and do another plug chop,looks pretty close though.I usually had best luck with a 27.5 pilot.

welcome aboard. sounds like you got a good deal on your bike. good to see you are taking the right steps to keep it running also. i agree with firebanshee, bump up a size on the pilot. plugs look pretty good. if it runs strong you may leave it alone. maybe just lean the needle one clip to liven it up a little more
