superbad7 Posted May 21, 2010 Report Share Posted May 21, 2010 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 Quote Link to comment Share on other sites More sharing options...
springer Posted May 21, 2010 Report Share Posted May 21, 2010 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.

T_Shee Posted May 22, 2010 Report Share Posted May 22, 2010 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 Quote Link to comment Share on other sites More sharing options...
