nwitthus Posted May 4, 2007 Report Share Posted May 4, 2007 I just got a timing plate and a 200w stator I plan on going +4 I have 18cc domes and run 110 will I need to rejet the bike or will every thing be the same just more low end power?

No you dont need to re-jet. Quote Link to comment Share on other sites More sharing options...
nwitthus Posted May 4, 2007 Author Report Share Posted May 4, 2007 thanks for the info if I go more will that give it more power on the low end and less on the top end Quote Link to comment Share on other sites More sharing options...
Screaming Yellow Zonker Posted May 4, 2007 Report Share Posted May 4, 2007 the more timing you add the less low end you get. Quote Link to comment Share on other sites More sharing options...
blowit Posted May 4, 2007 Report Share Posted May 4, 2007 the more timing you add the less low end you get. The Banshee will gain both in top and bottom end with the correct ignition advancement. Top end will start to decline when max advance is approached. brandon Quote Link to comment Share on other sites More sharing options...
nwitthus Posted May 4, 2007 Author Report Share Posted May 4, 2007 so should I go +/- to gain low end I am not sure to the different answers Quote Link to comment Share on other sites More sharing options...
ClimbAnyHill Posted May 4, 2007 Report Share Posted May 4, 2007 The Banshee will gain both in top and bottom end with the correct ignition advancement. Top end will start to decline when max advance is approached. brandon You're saying when it hits top end, you mean when it hits a certain gear? If I go +4 on my stock t5 with 300 jets & K&N pods, what kind of top end will I loose?? Thanks. Quote Link to comment Share on other sites More sharing options...

Top end will start to decline when max advance is approached. brandon this is new to me... please expalin... when you advance your gaining bottom end at the sacrifice of top... so how would it gain both? your times might be faster yes but gain power in both? i dont think so...

Wrong, simply stated, the Banshee has a lazy ignition curve (retarded). Yes, if OEM ignition is dead on from the factory, you boost bottom end and lose some top but the Banshee needs advanced ignition just to get power back where it needs to be. On the dyno, we see boost across the board until around 4-5 degrees advanced and then top end we start to fall off. This is assuming stock ports and 21cc heads. OEMs hardly ever put timing right at the edge because of assumed liability. Most OEM products will benefit by simply moving up the ignition slightly. Please look at Factory Pro timing goods. They have made a business by simply bumping ignitions a couple degrees and it works! This is always true for all machines but in the case of the Banshee, it is.

Brandon http://www.factorypro.com/images/dynochart...%20adv_comp.gif Here ya go! Please note that the power NEVER falls below the stock power curve anywhere in the RPM range. The reasons for the power increase are sited above. Brandon Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted May 4, 2007 Report Share Posted May 4, 2007 do they ahve one related to a banshee? i have never seen anything that suggest both top and bottom end power gains from advancing timing on one... Quote Link to comment Share on other sites More sharing options...

I will see if I can find one of our dyno sheet with just the timing work. We lost some data a while back and not sure if that file was one of them.

dajogejr Posted May 4, 2007 Report Share Posted May 4, 2007 the more timing you add the less low end you get. Exact opposite.... Ignition programmers add timing at lower to mid RPMs to gain HP...but retard the timing at higher RPMs for better overrev... Quote Link to comment Share on other sites More sharing options...
