DreamShee03 Posted June 6, 2006 Report Posted June 6, 2006 Heres the deal I have a banshee with a lot of mods and need some help. It is bored 80 over with a pro design cool head and 22cc domes, a pro design impeller, v-force reeds, billet intakes without the boost bottle, 10mm reed spacer, cpi infame drag pipes, 34 mm pj keihin carb with clamp on k&n filters with out prefilters, and advanced timing plate. I dont have any port and polishing work and the crank is stock, stock stator as well. I am located at around 2350 ft and want to run 91 octane fuel because I live in the boonies and that is the only fuel I can find. What should I set the timing plate to and what jets should I start with and what clip position. Any help would be soo nice and if there is any thing you think I should know just tell me. Thanks Quote
dajogejr Posted June 6, 2006 Report Posted June 6, 2006 With stock cc domes and that elevation, you should be able to run +4 to +5 no issues. If I had to guess...you're probably around 120 PSI or so...way below the need for high octane gas. Just make sure your jetting is correct... Quote
DreamShee03 Posted June 6, 2006 Author Report Posted June 6, 2006 Hey thanks a lot i really appreciate it. If any one else has some jetting specs that they are using please tell. Thanks a bunch guys. Quote
dajogejr Posted June 6, 2006 Report Posted June 6, 2006 Hey...sorry I can't help with jetting on those carbs. Getting some PWKs next week...can't wait. However, in reading your mods again...you're missing out on some power, as you already know. When it's time for a top end...you might want to think about getting that crank welded...as well as a good port job. With all those mods, porting would be icing on the cake and really wake that bike up. Since you already have a great list of parts...I'd just tell your builder what you have...and they can port into that! Quote
DreamShee03 Posted June 6, 2006 Author Report Posted June 6, 2006 The crank was trued and welded by trinity but once it is time for new sleeves I am going with a 4mil stroker 5 mil long rod and a mx port job cause i kinda still like to ride at the track. What does trueing a crank and welding it acutally do. I had it done but I have no idea what it did. I didnt notice any difference or anything. Oh and good luck with the pwk's i hope you enjoy them.

dajogejr Posted June 6, 2006 Report Posted June 6, 2006 You won't notice any performance difference from truing and welding. They are strictly reliability measures. Welding prevents the crank from seperating at the journals, and truing it makes sure it is straight...within a very small tolerance, like .002 or so. Not sure on that exact measurement. Stock banshee cranks have problems once you start pushing some ponies...I'd say you're already there! Some aftermarket cranks claim to be welded...but, as many have found out...it's a good idea to have a skilled builder re-weld them... My builder said he's seen a few come undone...and I've read the same here...as well as other forums. Quote
DreamShee03 Posted June 6, 2006 Author Report Posted June 6, 2006 Do you think that my crank done by trinity will be good to go. I dont the thing blowning into pieces and braking my cases and then chattering the jugs. I was looking at a hot rods long rod stroker crank. You can see where they have been welded, but i have read many horror stroies of them coming apart. Are there any other brands that are a lot better Quote
dajogejr Posted June 6, 2006 Report Posted June 6, 2006 The hot rods (wiseco) cranks are just fine. Just have a reputable builder re-weld 'em. Jeff from FAST racing sold me the crank and welded that baby good! He's my first call for just about every banshee need (he won't loan me parts or extend me credit...however.... ) There are plenty of other good builders here, as well. Hard to answer your question about trinity...as someone else posted here a bit back. They are a large company. If you got some slacker/part timer/rookie...welding your crank, it could be an issue. If one of their senior guys did it...you should be fine. I've read more bad about them than good here, and on Planet Sand. However....it's not fair for me to bad mouth them or give them a bad name because I personally have never dealt with any of their products or engines. So...sorry I'm no help, but...just trying to be honest. Quote
DreamShee03 Posted June 6, 2006 Author Report Posted June 6, 2006 Thanks for all the help. I will do some more looking and see what I can come up with. Once again thanks Quote
