Recommended Posts

I plan on racing my banshee in a hare scrsmble series this summer.I dont know much about these bikes.So any help would be app.I have .020 over cyl. fmf fatty pipe,the carbs are not stock but the say mikuni and the are round slide.Boysen carbon fiber reeds and rad valve,and the carbs use the stock boots if that matters.The head has been milled,and a k&n.Went up two teeth on the rear sprocket,a barnett clutch,boost bottle.I dont mind the way the bike runs but was wondering if it could run better for what i am doing?I think the rear shock has been revalved it riders real nice and works front shocks.If anyone could give me any advice if I have something wrong.I plan on posting pics shortly.Thanks

If it runs good, run it. The best thing you could do, to set it up for XC, is get tires. 22" front and 20 or 22" rears. 6 PLY! I would go with either holeshots or maxxis RAZRs. Check the rules for the race you're going to be running, because they might require you to have a tether kill switch and/or nerf bars also. Skid plates would'nt be a bad idea, either.

Sounds like you should be running pretty good like that. The first few times I ran, I was dang near setup just like you.

 

Only other things I'd add are timing, tires, and suspension. Advancing your timing 5 or 6 degrees will help a little all over and just make it peppier, and the tires will really help out with traction in those conditions. I'd recommend the Maxxis I-Razr, not the typical Razr everybody knows, but the I-Razr. Rocky Mountain has them on their site and they hook up good. Bill Ballance runs them in XC Nationals if that means anything. The tires will run $150 for the rears and the timing is miniimal cost, and free if you feel adventurous.

 

The last one I mentioned, suspension, is by far the biggest. Right now, your motor will outperform your stock setup, no question. Some shocks up front will make a huge huge difference and how fast and how competitive you'll be. You can get some Works up front for pretty inexpensive and be twice as competitive. Have your rear rebuilt and you'll have a machine that handles and performs night and day difference.

 

You'll probably also need nerfs and a tether line.

 

On my bike, I had pipes, nerfs, and a coolhead then the rest of my dough went to suspension. Suspension is absolute key. If your totally in it for fun, go run it some and see, your machine is plenty capable as it sits. Most of all, have fun yo!!

when you advance the timing the sparks ignite sooner providing more time for the fuel mixture to burn completly,increases cylinder presure ,creating more power.However if it is advanced too much this will cause Detonation. this is when the mixture ignites before it is supposed to . to prevent this you have to run a higher octane fuel.

 

Anyway, I also race harescrambles and the best tip I can give you is PRACTICE!!!

Most races are 1-1/2to 2hours long,get some good practice and be consistant!!

depending on the cource there may be some obstacles logs,small trees,whatever practice jumping or riding over them. One of the best feelings is passing a guy that is stuck on a log!!!

I raced the mhss last year riding my girlfriends bone stock 250 ex after tearing up the banshee pretty good in the first race of the season.I missed two races and still finished 2nd point and missed first by one point to a guy that made all the races.But that bike put a hurtin on me.So hopefully I can stay on top the banshee this year.Not that it is easy but should be easier than riding the 250ex,After the first 20 mins it felt like the shocks quit working all together.So hopefully the banshee will make it easier for me to go faster.

the pipes you are running are gonna be a decent pipe for woods riding etc, but your gonna find in the tight stuff your gonna be clutching a lot to keep the rpm's up.

 

My one banshee has fatties on it and I cant stand to ride it with them on compared to my other shee with LRD's.

 

Its my first pipe for my other banshee and will be the last unless I go big bore adjustable (if they recommend it). They are very nice pipes, never have to clutch in the tight spots, have a nice smooth long powerband hit that allows you to ride in a sweet spot that gives you a lot of torque, and the best part about them is that you can adjust them to your riding style and to the rest of your quad. When you adjust them, it adjusts where the powerband comes on. I have mine turned 2 turns off the latest it would come on, and have a ton of power still off idle, and it puts me in that sweet spot that I'm not quite in powerband but with a little blip I have all the power I could want. The broadness of the powerband hit is real nice for in the woods, and kinda feels like a 4stroke in a way but that 2 stroke top end follows right behind it and pulls as long and hard as a set of top end pipes like T5.

 

 

I'd run the fatties, see how you like them, and if you find yourself clutching a lot and arent liking the more of a lightswitch powerband hit, and want more power out of the powerband range, LRD's might be something you might want to look into.

 

I love them and wouldnt trade them for any other pipe.

A steering stabilizer is also a good idea. Just put a new Denton rebuildable on the 450 and it is awesome.

 

Handguards also a good idea. Keeps the crap out of the controls, and helps with flying debris to keep your hands roost free and safe.

 

Good tires and good skids are always a safe bet. Good rims also nice, dont want a blown bead to end your day of racing. I've been running 21" fronts and 20" rears forever and have yet to have clearance issues when riding. The places I have had trouble well it would have taken some 33" super swampers to have done much good, live and learn the good path and not so good path through the woods I guess.

 

If you are still running the stock pegs I used to dremel mine and put a little bit of a point on them for better footing when the going gets wet and muddy.

 

Some good suspension is key like SREDISH said, can make the difference at the end of the race from making you feel like the the banshee rode you instead of you riding it.

 

The banshee is definitely fun in the woods but can be tiring when you're running all out for 2 hours. Dont foget about all the things to make your ride more comfortable when it comes to you also not just the bike. There are always things you can do personally to help prepare you physically. If you've already done a few races then Im sure you already know this though.

Definitely and definitely. I wouldnt be in the woods w/out handguards, because ive hit my hands on branches and stuff and that isnt fuN!!! Sharpening the pegs helps a lot too!! You seem to have a good set up.

 

Spray WD40 all over it or crisco or something will help the mud stay off better. You can get a lot of weight added from mud.
