i have a shimano deore mega 9 crankset. can i use an xt 8 speed rear mech or does it have to be a 9 speed?

You probably need to repost and clarify a few things-  do you mean crankset (which is the front three gears) or cassette (which is the gearing on the rear wheel, usually 7 - 9 speeds)? Also, by rear mech, do you mean derailleur, or rear cassette?\n\nI can tell you this - when Shimano moved from 8 to 9 speeds they changed the chain, so a 9 speed crankset and an 8 speed cassette might be problematic.\n\nIf you are only worried about your rear derailleur, then you should not have much of a problem - just set your adjustment screws correctly and go.

your best bet is to get in touch with the guys who built the motor and know it the best. these guys will tell you the right answer and they wont just be guessing. D.S.S.  Phone: 630.587.1169 or e-mail ecom2000@dssracing.com and here is their website http://www.dssracing.com/

The timing specifications would depend on whether it is a V6 or an 8 banger\n\nDo you know which?

Pretty much all cassettes, deraileurs, and chains are compatible.  However, you need to make sure to get these items also compatible with your shifters.  You can't use 8-speed shifters with 9-speed cassettes, etc.

Not really...\nThe 3.8 is a 6 cylinder, 4.6 is an 8 cylinder motor.\nThe 3.8 supercharger would be the wrong choice for the 4.6

dude, XTR is up to 9 speeds on the rear cassette. 7 speed was like 10 years ago, litterally.  \n\nsure, you can use 9 sp cranks with 6 speed cassette, just use the 6 speed chain (6,7,8 speed chains are the same width) it just when you go 9 and 10 speed, the chains get narrower.  there will be some side play on the front chain rings, but it shouldnt effect performance too much, especially since old 6 speed stuff is pretty choppy anyways.

as far as am concern we also heard something that bajaj will introduce new pulsar dtf-i  220 cc but still not confirmed . but i thnk that yes there is a bike coming frm bajaj that will compete with ongoing hero honda karizma. so till then wait for that mean machine

If you find out, tell me. I have the exact same bike and my chain just broke. I went to the local bike shop and they want $25 for the chain. They also said they probably woud recomment changing the front gears too, since both parts usually wear out at the same time. That's going to be another $50 with labor. Go to the Mongoose bike website, they might have the info on size there.

Yes the strait cable is the best choice on a racing bike.  A gyro will actually make the brakes much weaker especially if you have a v-brake.  Strait cables are the best choice for racing because they allow direct pull giving you the most powerful stop possible.  Unless you have disc brakes which are pointless and hendering on a bmx bike.

You need to expand your question.  What type(s) of engines?  Exactly what cutoff time are you taling about?

Technically your bike has 21 gears--the number of rings on the front times the number of rings on your cassette in the back.  However, you don't really have 21 usable different gears.  This is because:\n\n1) Depending on how many teeth are on your chainrings (front rings, you have 3) and your cassette (7 rings on back), you may have some gears that repeat.  It is all about the ratio between the front ring and the back ring the chain is on.  For example, let's say your middle front ring has 38 teeth and one of the rings on your cassette in the back has 19 teeth, you have a ratio of 2 to 1 when your chain is on these two rings.  If your smallest ring in the front is 28 teeth and your smallest ring in the back is 14, you again have a ratio of 2 to 1, so these gears are actually the same.  \n\n2) There are also certain gears you should not use.  You should avoid cross-chaining--being in smallest ring in front (closest to the bike, on the inside) and the smallest ring in back (farthest away from the bike) or largest in front (farthest away from bike) and largest in back (closest to the bike).  Either of these gears, or close to them, puts a lot of stress on your chain because it torques it sideways.  This will cause additional wear on the chain and shorten the life of it.  Most bikes will allow you to do this because the chain is put at a length to allow for it, but it will also likely cause your chain to rub somewhere and also possibly make your bike not stay in gear very well.  \n\nHowever, these days, rather than multiplying the number of front and back rings to get speeds, bikes are now often referred to by the number of rings on the chain ring and cassette separately.  You ride a 3 by 7 (3x7).  A double road bike with a 10 speed cassette (typical of today's high end road bike) is a 2x10.  A more touring oriented road bike often has a triple chainring and is likely to be a 3x9 or 3x10.  A fairly typical mountain bike is a 3x9, but there are a lot of 2x9 or 3x8s out there too.

There are an incredible variety of gearhub powered bikes.  \n\nSee www.harriscyclery.com for your 3 speed parts and repair directions.  \n\nThere are 3 speed cruisers, 7 speed crusiers, 8 speed crusiers, these all come in a modern look or a retro look with both steel and aluminum available.  \n\nThere are 7 speed mountain bikes, 8 speed mountain bikes, 14 speed mountain bikes, and coming soon, a 9 speed.  \n\nThere are also 8 speed road bikes.  \n\nNone of these have derailleurs at all, and they all have gearhubs like your 3-speed.  ;)

The main advantage is that the compact crankset gearing is much closer to the high cadence riding that is the current trend in modern cycling.  With a standard triple crank you have 30/42/52 chainrings, from which most people use the 42 and 30 rings.  The 30 is a little too short for most hilly rides, and basically you're spinning super fast to get up a hill.  The 42 is   a bit too small for barrelling down a hill, and the 52 is so steep that it's rarely being used.\n\nThe compact crankset has 50 and 34 tooth gears which are theoretically better for the way most cyclists ride today.  The 34 gives you short enough gearing to get up big hills but is not quite as short as the granny gear on the triple, and the 50 gives you the speed in a manageable dose.\n\nA couple things to consider, though.  In order to switch to a double compact, you need to replace a fair number of components, including the bottom bracket, cranks, rear derailleur (optional but highly recommended), front derailleur and possibly your left shifter.  You might be able to get what you want from switching out the cassette on your bike, which is of course a lot cheaper.

uh its hard to explain depending on the bike race bike or a trail bike? ive got a four stroke an XR450/get the speed that feels comforable to you in 2nd or 3rd gear rev it slightly/shift/pop the clutch/and lean back/while ridin it you'll have to keep ur balance and keep the throttle right, when ur ridin it its all in ur right hand w/ the gas thats the part thats hard to explain>>>

you'll need to make the adjustment at the rear derailler.\n\nHowever, best advice, take it to a bike shop and ask them to show you. once you learn you will save big $$$$$.\n\n(Basic rule is, when standing directly behind the bike, looking at the derailer adjustment knob. a right turn will adjust the derailer down, a left turn will adjust it up......figure out which way your gear changes are missing, ie up shift or downshift. adjust incrementally until the gear 'just' changes....that should see you right)...good luck!

You should shift based on your cadence- your pedalling rpm.\n\nKeep your pedals moving at the same speed, and shift to maintain the pedal speed.\n\nThe larger chainrings (on the crank) give you giant leaps in torque while the cassette (in the rear) fine tunes your efforts.\n\nIt really doesn't matter how you shift the bike, as long as you avoid using the two largest sprockets and two smallest sprockets whenever possible. In fact, I would recommend that you NEVER use the large/large combination, and use the small/small only as a starting point if necessary. \n\nMake sure you are pedalling when you shift, and that you only shift the front or the rear at a time...don't shift front AND rear derailleur at the same time.
