I have a few questions on these gears. Correct me if I am wrong, the straight cut gears vs the helical stock cut is to not side load the crank with the helical pattern? And they stock ones are helical likely for noise reduction? What is the benefit of the ratio change from 2.68 to 2.86 to 1 on the gear sets? It seems to me you could do the same with sprockets and chain.

I have a stock banshee transmission that I bought assembled used. After I put the engine all together and started and ran it. The transmission pops out and back into first gear. All other gears seem to work fine, it's just first. I am splitting the cases now. Anything I should look for besides the obvious shift forks and gear dogs?

The Shearer pipe stingers are a bigger diameter. I checked it out.

What did you guys have to do to put them on?

Has anyone tried putting Toomey silencers on Shearer pipes. I like those silencers best out of all the pipe brands.

I bought one of these for my daughter. I don't want to over paddle it. Any ideas on what works good on the little 250.

Has anyone had any problems with their Shearer inframe silencers. I have a set of these pipes/silencers that I bought new 2 years ago and the left silencer is falling apart at the tip. Rivets loose end cap loose etc. Has not been wrecked or hit, just ridden sand only.

They are defininitely ground different. Point shape is longer and they have a extra clip position from what i remember. They ran good for me. Never tried them on a dyno or anything, just put them in and ran em. I let them go with the t5's that i sold.

How do they run? Any good, make more hp? A friend is doing a top end and ordered the kit. What do they do to your jetting as far as changes? The pistons are defininitely cut different.

I gots me a #7

I ended up doing a compression test before I left, at my elevation in Utah I had 170 psi on an un-broken in motor. It has been my experience that they usually gain 5- psi when they break in. I ended up buying straight race gas out of the pump, 110 Sunnoco in Yuma, and backed my timing down to 0 degrees on the plate. I never did do another compression test down there to see what it was but it had to be close to 190 psi I would guess. Everything worked out o.k., the engine ran good but I took it easy on it for the most part. Got after it a handfull of times on the sand highway where they race on the last day. I was going to change my domes but the air freight never made it before we left. Thanks for the info.

If I buy 110 or 112 race gas, how high roughly can my compression be on it safely. This is stupid because I have not done a compression test on my motor yet to see what I got but am running out of time. I have a good comp tester and will take it with me when I go. I have a Serval 4 mill, 35mm carbs. I have 22cc domes in my head. I have not run this combo before. Any Ideas on what it should be compession wise at California. Glamis is 335 feet. I am at 4600 or so.

Thanks for the replies. I bought the Shearers. They are a tight fit on there with my carbs/filters and intake I got. Look pretty sweet and seems to run good but only had it in the neighborhood so far.

It is all built, Serval 4 mil.....now I need to buy pipes. Which ones. I have 35mm carbs. Sand dune riding only. I thnk the CPI pipes look kind of cobbled and the Shearers dont fit good from what I have read. Or are they close enough it won't matter anyway? I am a heavier rider i.e. 250#s

As a side note, the final hill climb for the Rocky Mountain Hill Climb circuit is in Billings Montana on a hill called the Bentonite Nightmare. I have not been to that event but the footage of it is insane if you have not seen it. There is a approx. 20 foot vertical cliff at the top and the bike catchers hang down on harnesses and ropes like rock climbing equipment to hook the bikes (sometimes) as they fall down it. Not sure if they do any ATV stuff at that one. I am going to go check it out one of these years.

Heres a little Widowmaker history of what I know. The original Widowmaker hillclimb started back in the 60's some time and the original hill was on the South end of Salt Lake City. If you have ever seen the old movie "On Any Sunday" there is some footage of it on the movie. Pretty cool. They quit running the original hill in the 80's sometime, I don't remmember when, but when I was a wee pup I went a few times to see it with my pops. There was slim to none security and safety. It was a sanctioned climb but with a very rowdy crowd. I remmember hiking up the hill right next to the sideline stringer and watching the bikes go by and getting hit with dirt and sagebrush. Seeing the catchers try to catch the bikes on the hill from 10 feet away on the sideline. Only a thin plastic ribbon keeping anyone off the course. Very cool, very dangerous. It got shut down, I heard because of the rowdy crowd having fights, I think there may have been a rape one of the last years, drunkeness etc. The cops and city got sick of it and it was almost in a neigborhood at this piont due to city growth. There are now big houses there. The original hill was 1500 feet. They would move it some yards every year to the side of last year to keep it on original untouched ground. There was a span of 10 to 15 years when there was no Widowmaker anymore. To make a long story longer, fast forward to now. The new hill is in Croyden, Utah. A smalll town above Ogden. It is on private property owned by a family that owns a gravel/concrete plant. I believe the champion hill is 1000 feet now or maybe 1200, so a bit shorter but as original it is on fresh untouched ground every year. No Banshee or any Atv would ever climb either hill new or old. The sagebrush is 2 to 4 feet tall, It is VERY steep, and there is no grading or trail of any kind at the beginning of the event. If you have ever tried riding through sagebrush, it picks up your wheeler off the ground and you spin out or flip over backwards. Not to mention the various rocks ledges and holes you cant see.Eventually a groove gets cut into it at the beginning but the higher you go the less trail there is. Usually only a few of the unlimited bikes even top it at all. It is a well run family frendly event now with vendors etc. There is a ATV hill that they run at the same event. It is pretty impressive also but nothing like big hill. It is on the left side of the main hill, not near as long. Last time I watched it it had a turn in it midway up also. It is ungroomed mostly, with no sagebrush and no steps in it like your hill videos you guys are are posting. The dirt is virgin and pretty hard. I watched it and decided that I valued my Banshee to much to risk climbing this hill. Some were climbing it fairly easy but with lots of wheel spin and it is a do or die deal. If they stopped or missed a shift, powered out, wheelied up etc they were done. There was no stopping on it, you would begin sliding backward and HOPEFULLY the hill help would grab your machine. If not, down they went. I watched on poor guy get right to the top, wheelie up on his L/E Banshee (the black one with the flames) slid off the back and down it went. Have you ever seen how high Atv's bounce when the are tumbling down a mountain? We call it a YARD SALE when it happens to our sleds in the mountains, same thing. Speaking of which, they also run the big hill in the winter and put on a snowmobile Widowmaker event every year which is cool also. There you go, hopefully someone reads this even though this thread is so old, it took a long time to type it.

I have always worn work boots also but 2 years ago in glamis I caught a witcheye kind of crooked and by surprise, I saw it last second and did not crash but it folded my left foot under the peg with my heel still on the peg.It caught my toe when suspension bottomed. I have a plate and 8 screws in it now. I consider myself an excellent skilled rider and very familiar with sand riding. It only took a second of looking back and I did not see it in the noon sun till I was on it. Tennis shoes and even work boots are not enough in my opinion, I was wearing work boots. My ankle will never be the same. I have not bought riding boots still, all the ones I have tried on fit like shit, and wouldn't flex with all the plastic bullshit all over them, I was hoping that someone had a great brand to buy. I used to never wear a helmet either, I always took it though. Then one ride I put it on, just for the hell of it and have worn it every time ever since. Just my .02

I dont have a picture. If you look at a bottom case half, on the outside, in the center where the crank sits, there are 4 epoxied holes from the factory. The holes are about 1/4" or smaller. Over time that can be a potential air leak, sometimes they start to weep a little.

I have a couple of questions about a engine build i am doing. There are 4 epoxied holes in the bottom of the case under the crank. Most guys I think just grind around the area on the bottom and add more epoxy. Has anyone tried drilling and tapping the holes from the bottom and Loc-Tite some set screws in there? Those holes look to have plenty of meat to thread, they go all the way to the crank bearing, I was thinking I would only thread them in flush with the bottom of the case.

Thanks for the info. I bought it new and it is a 2000. I didn't throw all of the bolt on parts at it at once, they came here and there over the years. I have always been on top of the jetting on it, jetting it for the different parts and up and down for when I have gone to California to ride. This machine has been extremely reliable and ran hard right up until it let go. I don't know that it was all that worn out. I am going to get into the crank, and might as well replace it, I am going to replace it with a 4 mil. What is the matter with the spacer plates under the cylinders other than the extra gasket? I don't want any porting. I may just clean the ports up myself. I like where the power spread is stock. I was looking at a Vito's crank, I like it because it is already welded. Is this one pretty good and last a long time? Has anyone done a 4mil on here without going all wild with the porting and carbs etc ? I was curious as to what the difference just the crank would make to power and how it would run ? Thanks

To make a long story short, 2000 banshee, I bought it new and the engine has never been apart. It has chariot head - 18cc, T-5's, K-N with no lid, and the timing is bumped up 4.5 to 5 deg. I jetted it and it has been good for 10 years. I did put a piston in the right side last year after it almost burned a hole through it from running out of gas while pulling our drag hill about two years ago. I put a stock piston and rings back in and rode it till now. Our elevation is approx. 4600' and I am sure I am on the ragged edge for pump gas. My plugs have always been a touch rich chocolate color. Running a bowl last weekend it melted down on me good this time. I read the post on how to build/use a leak down tester and plan to do so and have not torn the engine down. I rode 15 GPS hard dune miles before it went down. Pulled the plug on the right side, the electrode is gone, melted away and the plug is full of melted aluminum.The other plug was still brown colored. After a few minutes the engine unseized and I was able to get it started again on one cylinder but could not get the bad plug back in because it galled all the threads in the dome from being melted. I got pissed off and worried, was getting dark and cold. It made it maybe 1/4 mile back and that was the end of it. My friend was on a yz 250, there was no way he could pull me out of there. It still turns over but there is nothing there. I was curious on if you guys had any thoughts on what happened, if I lost a crank seal, or what I should be looking for on the pistons. I am planning on going all the way to the crank on this rebuild, I'm sure it was due anyway.

Well we made it out there, we put 78 miles on the bikes, My buddy rides a KTM dirt bike and it has some kind of trip meter thing on the bars. We ended up leaving at 12:00 or so on Sat after his bike crapped out, way in the hell out there to the west towards the edge of the dunes. Friday we were the only ones out there till Sat. morning. Kind of funny we rode all the way due North as far as you can go on sand Fri evening and on our way back it got dark on us, we were the only ones there so there was no lights, campfires, or anything so it was a bit dicey getting back to the truck.

Thanks for the info, we are just going to run up there for one night, come home Sat. afternoon sometime. We'll be in a purple ford dually.

Some friends and I are going to make a run up to Killpecker on Aug 28th from SLC and check it out. Is there any water,toilets etc or is it totally primative camping? Do you have to pay anything? From what I have heard the road in there is rough. Where are the neat bowls or hills we need to go find? Thanks
