Whyzedtwofiveoh Posted September 9, 2009 Report Posted September 9, 2009 Hi guys, im new to the forums and have a few questions. This coming saturday im going to be picking up a 1989 Banshee. It has a new topend with under an hour on them, the prievous owner went down 1 tooth in the front gear but also has the stock gearing. It has intake and exhaust porting and its bored out a bit from when he rebuilt it. Anyways i was wondering what mods i should purchase first? Also is there going to be much of a powergain over stock because of the porting or is it insignificant? Thanks Quote

alf44 Posted September 10, 2009 Report Posted September 10, 2009 find out if the timing has been advanced and what type of port job and bore where done too it. Quote
Whyzedtwofiveoh Posted September 10, 2009 Author Report Posted September 10, 2009 It just stock pipes. Its only bored out maybe 10CCs or something. Its got OEM yamaha cynlinders and i dont think the timing has been advanced. The port job was nothing big either, he did not widen them just raised them up a bit. Im thinking of getting some Toomy T5s for it. Quote
sheeBnasty Posted September 10, 2009 Report Posted September 10, 2009 I would say pipes and bump the timing up..just don't really know how it is going to run with a "do it yourself" port job..but I had a 99 Shee .20 over dune ported with T5, plus 4 timing, and stock carbs...and it ran damn good for a play bike...

alf44 Posted September 11, 2009 Report Posted September 11, 2009 Yup. Plus 4 timing and t5s is a great starting point. after that decide what type of riding you do the most and have it ported to you type and riding style. Quote
