joeytvr Posted January 27, 2015 Report Share Posted January 27, 2015 I just finished a total rebuild for my sons 99 banshee. .080 bore fmf pipes for now uni filter +8 timing etc, basic build He has lots of his friends calling him out with raptors, dirt bikes etc. Sooo I am running a 20x10-9 rear tire and a 13/40 sprocket setup Theres a local banshee guy with full drag bike. He says a 16/38. Sounds like alot of gear to pull? Any suggestions? liz450 and raptor i doubt will give us much trouble. But theres a ktm 250 i gotta get things right. lol Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted January 27, 2015 Report Share Posted January 27, 2015 wow. +8 on the timing? that's excessive. Quote Link to comment Share on other sites More sharing options...
Pasi S. Posted January 27, 2015 Report Share Posted January 27, 2015 Are you going to race on sand, dirt or asphal? 300ft, 500ft or longer? People would like to hear more info to help you. I´d say +8 timing is quite alot. And stock 14-41 gearing is pretty good starting point. How much your son weights? Quote Link to comment Share on other sites More sharing options...

joeytvr Posted January 30, 2015 Author Report Share Posted January 30, 2015 Its bored .080 over prox pistons fmf fatty pipes and silencers carbon and fiberglass dual stage reeds stock ports timing is at +6 right now running the br8es plugs Gearing now is 13/40 320 mains need to jet a little leaner yes ltr450 stock. Gonna find out year. its alittle older of a bike 500ft on dirt 1/8th mile on street. with a 13/40 gear what type of mph will it run. Do not want them pulling and his banshee maxed out. Thats gearing concern. Quote Link to comment Share on other sites More sharing options...
joeytvr Posted January 30, 2015 Author Report Share Posted January 30, 2015 +8 seemed a lot to me also. One of the bigger all out banshee drag guys here also has a atv repair shop and builds bikes for others of course. Says he sets them all at +8. Mine is actually bit less than +6 cause I was nervous. lol I appreciate every ones opinion and do not seem to trust him whole lot. Bought the bike from him that needed rings and bearings. Bike was total trash. case and trans was all I could use on engine. paid $900 and now 3k later I have a new bike and a extremely excited kid. so alls good now.

BANSHEEBEEFM2M Posted January 30, 2015 Report Share Posted January 30, 2015 If your not running race gas turn timing down to +4. Is the kid light? Quote Link to comment Share on other sites More sharing options...
BANSHEEBEEFM2M Posted January 30, 2015 Report Share Posted January 30, 2015 500 ft or 8th mile if the kid ain't too heavy I'd go 15 up front and 40 or 41 in back. Higher gearing will help him keep the front down off the start too Quote Link to comment Share on other sites More sharing options...
joeytvr Posted January 30, 2015 Author Report Share Posted January 30, 2015 hes 130# im only 155 myself. lol My chain cannot to a larger front. I may go to a 39 rear so I can go up on front some? What kind of top speed range with this setup curious? Quote Link to comment Share on other sites More sharing options...
BANSHEEBEEFM2M Posted January 30, 2015 Report Share Posted January 30, 2015 Idk maybe 75-85 mph Quote Link to comment Share on other sites More sharing options...
joeytvr Posted January 30, 2015 Author Report Share Posted January 30, 2015 Gonna order a 38 rear. brand new chain and no more reach. Plus with my case saver i am not sure how big of front sprocket I can fit. 75mph is basically stock. would we not be able to gear for more top end. Wanna make sure we do not run out of gear before 1/8th mile. Quote Link to comment Share on other sites More sharing options...
SlowerThanYou Posted January 30, 2015 Report Share Posted January 30, 2015 I wouldn't stray from a 14/41 sprocket combo. We have played with the gearing a couple times on our play quad. The best times & mph have come with the 14/41 combo & a 20.5 dia. tire. My son weighs 210-220. Our best mph in the 1/8 was 80 mph & 1/4 mile 92 mph. I think most of the information is in the thread below. http://bansheehq.com/forums/index.php?showtopic=173690&page=3 Quote Link to comment Share on other sites More sharing options...
