Hey guys, I am back with the same banshee, same setup, same riding conditions, the only diference is the ambient temperature, is getting seriously hot and the temperature when riding gets up to 100F, yes that is very hot. Based on what worked fine on the 70F setup (50 pilot, 195 main, DGH needle with clip on 2nd notch), What pilot, main, needle and clip position would you recomend for 100F? Snop I know you have the right answer for this, I hope you can help me again with the single carb set up. Thank you all

I know you can get a 200w stator from Ricky Stator, but I didn't know there were 250w stators avalible, how makes those?

If I decide to go with the agresive dune ported stock cylinders, 4mm cranck, 19-20cc domes and CPI inframes... what do you think of the 2 into 1 intake with 35 or 38 PWK airstriker? do you think it will pick up the bootom end?

I get your point and I agree. That's what I'll try to do, try to get a non-ported used banshee 02 - 05 with either CPIs or T5s (I am monitoring for the right deal localy) and start from there. I know the whole project will be expensive, so I'll try to save on the big things.

I'll take any ideas, even if they are over the budget. Like always, I'll have to make my choices of what to do now and what later. I really like the setup you sugested, just a couple of questions. why did you pick the 39mm PWK, why not 35s? how much compression are you planning for?

The starting point will be a stock banshee in good shape (no repair needed) and 4-5K

OK, I am getting the idea on the engine. Definetly a 4 mil either stoock cylinders with agresive dune port or a cleaned up cub. On the lights, where can I get nice HID or PIA headlights? how much lights can I use with the stock stator? I am thinking of adding one or two flood headlight under the bumper, just like a sand rail, what do you think?

What exactly did you do with the timming? cool head? For the rear tires I was thinking of the Skat Trak Edge, how are they compared with the SSII?

I thought the Cubs were intended for drags, and therefore for top end, and when dunning I think you are looking for for bottom/mid range power. I am surprised nobody has mentioned the 2 into 1 intake, I think it helps the bottom end and throtle response. Would you guys consider it as a must for a dunner?

Thank you for your advice and excuse my next dumb question, but, what's the most significant benefit out of a stroker? torque? bottom end?

stock bore?

Any one else?

There is nothing wrong with it, I love it. And I love its stock look. I know if I change suspension, headlights and cut the fenders it will loose the look. That's why I am thinking of building a new one. But as you should know, everything is on sale. If you are interesdet PM me.

Hey guys I need all your dunning experience here, I want to build a banshee exclusively for dunning at Glamis. 120% dunes. I you were to start with a fresh stock and well cared banshee, what your preferences would be in: - Engine (include porting shop) - carbs - intake - pipes - head / domes - clutch - sand tires - suspension - swing arm - headlights (I love nightdunning) - misc. mods Thank you guys

This is my dune ride, mods listed in signature. the pic is old and doesn't show the 2 into 1 carb setup.

Yes it does, increases the spark energy and I think the spark itself lasts longer I agree 100%, do you remember the feeling when you went from stock pipes to performance pipes? same feeling when you get your cylinders ported.

It is call "Air screw" because when you "open" (counter clockwise) lets more air go through making the mixture leaner. Thinking this way makes me remember when I'm adjusting it. I hope it helps you too.

What carb's are you using right now? smaller domes, 19cc or even 18cc will give you better throtle response by sacrifycing a litle top speed ($80) Dyna CDI box, you will need to rejet with a few sizes larger for this mod. ($300)

I love seeing banshees with street bike engines. Don't loose the initiative and if budget is not a problem get a nice engine and put it in your banshee frame. JUST DI IT ! ! :beer:

Hey guys here are the atmospheric pressure for differet altitudes Sea level - 14.7 psi 1000 ft - 14.2 psi 2000 ft - 13.7 psi 3000 ft - 13.2 psi 4000 ft - 12.7 psi 5000 ft - 12.2 psi From this list you can assume that Every 1000 ft atmospheric pressure drops 0.5 psi or .0005 psi/ft So if yo want to know your local atmospheric pressure to the decimal point you can use this formula: P_atm = 14.7 - (Alt * 0.0005) P_atm: Atmospheric pressure in psi Alt: Altitude in feet For 1490 ft your atmospheric pressure would be 13.95 psi As a disclaimer: This calcluations ar from from the book, actual atmospheric pressure can be differet, usually higher, due to weather conditions, temperature, humidity, etc. This calculations are conservative, that means you will always be on the safe side by assuming lower atmospheric pressure your CR will be higher

I know Trinity makes one.

Pessure tester and torque wrench are very useful tools, I did't have any of those tools when bulding my own engine, I used my friend's, and I have not needed them in two years. The guy who started the topic is not building a monster bahsee or running a dragster or a cuby. I'm trying to save te guy some bucks that he may need for latter mods. By looking at the pic in your sig I can tell you have spent a lot of time and effort into your shee, and looks like you have been on this bussines for a long time. And I have a looooot of respect for you guys how have a lot of experience cause you help us save money and have fun with our toys not only when riding but when fixing. All I want to do is follow that trend and save our friend some money.

It sounds like they are using different units than psi, maybe inHg (inches of mercury) google fo a pressure convertion table, atmosperic pressure around your altitude should be around 14.5 to 13.5 psi thats for sure

I am not saying is wrong to run 50/50, I am just saying that does not fix detonation problems. Fuel has the property of containing energy (cant remember the name), race fuel contains more energy than pump gas. if you mix them you will get more power than just pump gas. with 19cc domes at sea level will get you 183 psi (www.nossmachine.com) therefore 12.6:1 CR I would use not less than 110 octane, but no matter where you get your fuel, always ask if it is ok for your 12.6:1 CR Make sure the fuel is not oxigenated, that will require you to change the jetting

And don't get me wrong, i LOOOOOOOOOVE new tools and gadgets :beer:
