Hi Josh, My kits came with both sets but I only use the standards in my multi stage clutch. I cut the coils to regulate primary pressure. Would you be interested in trading your std's for heavy duties? Mine aren't gold but are still in the sealed Barnett pakage with the part number on it. Thanks, Ted

I've got three brand new packs of Barnett MT-42 heavy duty clutch springs still in there bags that I'd like to trade for Barnett standards. These come in YPK-27D and YPK-27DCF kits.

For less $$ they still offer the stock cover mod. It's real nice also :thumbsup:.

We ran a dirt digger with a Wilburn Motorsports multi-stage clutch last summer. Here's what we found out. 1/4 mile Asphalt Banshee 7300 launch RPM The bad: 1 - Without WAY more primary spring pressure the dirt digger slips much easier than other fibers. 2 - The Dirt Digger "muddies" the tranny fluid very quick. Had to change it often. (Every track day) The good: 3 - The Kevlar clutch holds up to heat real well. Stay's fairly consistant when hot. 4 - For what we put it through it wore like iron. We ran one of Jeff's clutches (FAST Racing) in 2005 and will likely go back to it next season :thumbsup: .

If you find the cable is OK Jeff at F.A.S.T Racing can set you up with softer springs.

Off the subject a little (not boyesen) but here's some asphalt comparison #'s Our first 1/4 mile asphalt Banshee was a mild 50 HP setup Changed from FMF to V-Force II's - No other changes Cut 3/10 off the ET and picked up 2 MPH

Yep' I'd leave her there. If you have access to a dyno, EGT etc. you could play with it to see where the highest numbers come in but even that will vary day to day depending on temp, weather etc. and I doub't you'd feel it in the seat of your pants. WOT plug chops work well and I'd say your mains are :thumbsup:. How does it pull off idle and up through the gears?

The band is a wider than 2mm which indicates slightly rich but if it pulls hard up top I'd run it.. The grey color is usually from a leaded fuel. Unleaded shows brown. What are you running?

First off I want to say THANKS for your service...As to your question, Some of the other guy's on this site might be able to give you a better answer but IMO I'd talk to Jeff at FAST Racing about doing some porting instead of the 4 mil crank. Good luck :thumbsup:

Aah Jeff, Once again you come through ...You da man

Cool, an Ohio brother. Let us know how you like the pipes!

By the sound of your post I question as to if its really the crank seal your talking about. Usually a leaking crank seal causes a performance and/or overheating problem because your bikes lean. Is what your seeing an oil leak from around the tranny output shaft (behind the front sprocket)? If it's not the crank seal you would probably be OK running it if you keep the oil up and you stay out of the creeks :biggrin: but fix it as soon as you can and replace ALL the seals at that time.

Lots of penatrating oil and an air chisel to work the bolt back and forth has always got them out for me. They can be real tough sometimes.

I like the chart on www.sidewindersprockets.com. From the menu items on the left click "gearing"

Great giveaway...Put me in! Thanks

Anybody out there? PM me...? Thanks

Barnett gives you a pack of Std. and HD springs. Most guy's mix them three and three. Adding the HD's gives extra holding pressure. If you use all 6 HD's it's a lot of work on the forearms in a days ride. Just instal them in rotation 1 std then 1 HD. As for the cushions...Throw them out. Their only used on the factory clutch. Are you using Kevlar fibers?

Some of you might have seen this same post on PS website also. I've been REAL surprised at how large a jet I might need for my new 39mm carbs and now I'm gun shy about seizing it. Any of you guy's here give me your .02 worth. Thanks for the help.

Current setup on our stock stroke cub motor 1/4 mile asphalt Banshee. 35mm Air Strikers- 165 mains, 40 pilots, DEK needles in the middle. Going with 39 PWK's. Anybody help with a jetting recommendation? We're at 1300ft. Thanks

On our first 1/4 mile asphalt banshee we picked up 3/10 and 2 MPH changing from FMF to V-Force II's

Don't know about the stuff your looking for but for the BEST in customer service you gotta call Jeff at FAST Racing. He's been very fair to me on pricing and is a great guy . He's on this site often. Can post his phone number later.

Pretty cool thing to do Red ...Put me in - Thanks

BG, Did you ever get the REAL CDI stock curve numbers from Dyna?? I've got one of the new ignitions from Wilburn motorsports and was looking for a baseline..Thanks

We top out 90mph flat at our local asphalt strip with 19" hoosiers and 16-40

Hi Jeff, Already got a lock up. Always keep you in mind when I go "shoppin" as the wife says. locogato,we are running 1/4 mile so we went with stock stroke.Hey I lived in Lebanon Mo for a little over 3 years back in the early 80's.Nice area. Ted
