i only have stupid 3g and no long distance, can someone send me his web site? i searched google and its a bitch surfin on a phone. need to send my cyls out for bore and pistons asap!

2 stage boyeseen carbon fiber pro.

your "mechanic" is a retard.

im sure he means balljoint dilbert. i used a flywheel pulleer rig in between both ends and turn it open to press one out then find a way to make a spacer to press out the other one.

someone makes a stick on strip. i think rmatv sells em?

i wanna go...

I think powervalves arent going to do a whole lot for drag bikes, but if you have a decent mild drag bike used for some general riding, they would be worth it. any trail bike or tight turn quad is going to benifit alot from it, ecause you gain alot more power in lower rpms, because the valve is in the exaust port and cuts off alot of flow/energy to bounce back into the cylinder that normally would not be "on the pipe yet" where the motor makes its power from. since they open all the way wot there is no restriction. I have rockets on my PV cylinders and make better bottom end torque than std mx ported cyls with pt mids and all the other crap, but still have all the high end I need. I also dont have that hard pipe come on. the electronics are a bit of a pain in the ass, and can be a bit of money, but if you can get those cyls for next to nothing it might pay off. I see rz parts on ebay quite often. For aany hill, dune, drag quad its prob not worth the aggrivation, but Id recommend it for any other typical uses. think of it this way, a stock banshee motor makes what about 36hp give or take, Im pretty sure the stock rz motors where between 60-80hp depending on where they were made, stock stroke, unported, ect.

Ive only ever thrown one, and it was because I put my g-force together wrong and the sprocket shifted.

I have a million records I would like to put on my computer,. is there any way I can record them onto my computer and convert them to mp3 or just to save them on the PC. My sub responds to 18hz and I can listen to records very loud without the needle vibrating and then it sounds like a helicopter landing in my living room. I dont have any programs, but windows vista. It would be nie no not have to flip and change all the time too, esp with the ol 7" ers. I have the wire already that goes from the rca`s to the headphone on the back of the computer which Im sure can be reversed to output/microphone or something?

yes thats a correction to me on the speed per cylinder. Then again, why are we bringing up 2 stroke diesel, and v degrees? why not try and answer he oringinal question. Im trying to stick to the yfz motor in comparison to another same cc 2 stroke. Where all these other things are coming from I have no clue. Weed eaters work, a 2 stroke made to run without a pipe will work with no pipe at all. I could stop the crank of a weed eater with my hand with a glove on. Im tring to stick to the original question, and the yfz motor isnt any 80 90 degree v motor, its inline. a single is a single. Whats the compression of a typical weedeater? does a banshee have the same port timing as a weedeater? I didnt say 2 strokes wherent strong. They typically make more hp than a 4 stroke per cc, but at higher rpms. 2 stroke motors dont have a broad powerband and I mean 2 stroke gasoline not deisel. A motor that would go into an atv chassis. IS the firing order going to change between a single? or an inline twin? here the firing order 1,1,1,1,1,1,1,1,1. 1,2,1,2,1,2,1,2,1,2,1,2. what other variable is there? fuck it I dont even care anymore.

I tried duct tape around both, that didnt work, then I got mad and used red threadlocker, so it never came off, and almost impossible with 20" pipe wrenches and a torch, but blue worked well. you can tighten it all the way and drill through the outside nut into the axle about 3/8", then make the hole 1 size larger in the axle, thread the hole in the nut and have a set screw for it.

actually it isnt that good. Its a very big shortcut to what I was trying to explain. I just now re read it and if you dont already know what Im talking about, it prob wont make any sence. :shoothead: I skipped around not fully expaining anything lol. cant type as fast as the thought process.

if you have access to a small enough telescoping bore mic, you can prob measure it through the exaust port w/o pullin the head.

if you get a good one, the endoplasmic reticulum will positivly charge the ion gamma difibulator powering the flux capacitor sending your bike down the road so fast you will travel through time. so wear a helmet.

You cannot compare any 4 stroke vs 2 stroke twin or single. I think on a 2 stroke motor, it is going to run more efficient than a single because you have twice the amount of force going at the crank per revolution. The pistons are traveling at half the speed to turn the crank. Since the pistons are moving slower, there is more time for the exaust waves to force its way with some of the intake charge back into the cylinder on a compression stroke. We all know that a 2 stroke also runs better at higher rpms because at lower rpms there isnt alot of sound energy back preasuring back into the cylinders. For this reason it may make a little more bottom and mid end power on a single piston motor. No matter what, a 2 stroke motor doesnt make good bottom end power because it only gets its power off the pipe. Without these effects from the expansion chamber, a 2 stroke would be a weak engine. No 2 stroke really has a wide powerband range. Any dyno chart you look at is going to look like the side of a mountain. A pipe can be made to manipulate where the range of power will be greatest, but its always in a short band, because that pipe is only made for timing waves to "supercharge" the cylinder at a specific time. Sound doesnt travel at different rates of speed. On a 4 stroke motor, the valve timing events are always the same. Of course the timing can be altered for a movement in power in a specific range, but it will still be in a wider smoother band. when the intake charge comes into the chamber it gets trapped inside and nothing escapes, so on the bottom end its stll producing lots more torque due to no charge escaping. At higher rpms, a 4 stroke is still running at the same efficiency. A 2 stroke makes more power per cc because its actually sort of being supercharged by the pipe, making it more a powerful top end motor on top of having 2 more combustion strokes vs a 4. The compression of a 4 stroke motor is also higher, which can work against it i a way because its harder to pack more air as the piston is moving upward to compress, and to push exaust through a smaller valve hole,. but the power still over compinsates for it. Kind of the same way it takes HP to turn a supercharger, but the boost and the power makes over compinsates for it. If you made tandom 250cc banshee motor and put it up against a single 500cc 2 stroke motor, with the same rpm range pipe and port heights, which do you think would win? The 500 would have a larger bore, ports and stroke, but I bet the twin would win overall, and the bottom/mid gain would be so much greater. It also takes more power to turn a valvetrain,. which a 2 stroke doesnt use, making it less of a maintanance hassle and more efficient. Running powervalves on a 2 stroke motor will build up a broader powerband, but no 2 stroke can be compared to a 4 on torque. In fact I dont think Ive ever seen a dyno chart from a 2 stroke motor where torque exceeded horsepower. I have however on many 4 stroke motors. Thats my .002.

I was under the assumtion a big bore was 68mm+ doesnt a 4mm stroker and 66mm make 396cc? what he has it listed as? which is still in a stock bore tollerances? 68mm+4mm=421. Its says big bore kit. Does that mean my 391 has a big bore kit?

you may be able to do it through they key, though I think a tether is a normally open circuit. I cant remember off hand. in other words when the cable is pulled its supposed to ground and kill the motor, so if you closed the circuit through the tether this means the cable will have to be pulled off. Correct me if Im wrong though. I cant remember for sure and I dont have my tester here. thats how the kill switch can turn the bike off while the key is still in the on position. they key switch is a cut off of main power.

these are my rz pv cylinders.....

no this is a good deal for a newer 4 stroke,...... 04 Yamaha yfz450 For Sale - $1500 http://fortmyers.craigslist.org/mcy/999181456.html

you may be able to run it like a relay. there should be a ground wire from your main switch on the bars that has a separate ground plug on it that your tether with plug into. the other wire from the tether should ground on the chassis. thats how mine works.

this is nice and all, but Im not contributing for someone elses profits that have sold myself and others garbage, which Im certain this is actually about.

The way I see it, the crank turns more and the piston/rods travel less. The pistons and rods work less to spin a higher rpm. This slower piston travel vs crank rotation will affect timing at the ports differently. Longevity of cylinder/ring life. Id consider a banshee motor more twin inline ratehr than a "v" twin.

yes, of course.

Somebody willl prob wah about it, but I have no problems just using yamabond 4 case glue. Never leaked. Its cheaper than one gasket, and will last several changes.

Just because I have nothing to do for about 10 more minutes why tf did you come on a banshee site to ask if its a good idea to get a raptor? Im pretty sure though Ive been quite suprized before most of the responces that come from people in the same bored situation Im in will tell you go with the banshee, possibly for the reason that the banshee is their primary preference. I never thought I was one of the brightest lights on the christmas tree, but Im really starting to wonder...... that thing looks like a dork, its a dork bike.
