Looking for new parts for my bike

Hey guys, I currently have a 2007 hardrock disc, I had the rims rebuilt 2 years ago, with alpine III spokes, and they are sturdy enough to support my 360lb frame. I however have been unable to ride due to my "deraileur" kicking, and I believe the problem is that because I am a big clyde, I am putting to much down force on the derailurs and crank set.

Anyway to cut to the punch, I have a fairly large tax refund coming in, and as I know I already have the hardrock frame and wheels, I know I just need to make 5-600 dollars to make this thing rideable, My goal is to do them over the winter, so I can get back into riding, and drop some weight.

Anyway this bike is going to mainly be used for riding on backroads//around my college town over the summer, the parts I know I need to upgrade are: Crankset, Derailurs, Brakes, and the front fork. Any reccomendations for parts would be great.

I'm not sure what you mean by "derailleur kicking."

By kicking, I mean it feels like the gear changes (I.E. I feel tension build up, and then it releases, and it sounds/feels like I changed a gear, even though i didnt)

Also, I am thinking about using sram x7 components for the new crankset, has any one used this?

The other thing I have been looking into is getting a new bike, I was looking at 29ers, and was thinking of trying a Kona Kahuna, Kona Mahuna, a hardrock 29er, and a trek wahoo, I believe these bikes should be able to support me, but may need a little bit of upgrading, has any one ridden any of these?

Also, have somebody double check the dérailleur settings. I've had problems in the past with indexed systems. It would get a little out of adjustment so the chain wouldn't seat securely on the cogs and I got a kickback/lash like you described.

Be careful of Kona bikes. I bought a Kona Kula Deluxe 2-9 that has a scandium frame. I spoke to customer support and the didn't recommend it at my weight which is 250. I've been riding it lightly over the past 2 years and have had no problems other than with the wheels and the spokes loosening.

I would also recommend checking the chain. Make sure you do not have a frozen link or links and check the chain for "chain stretch."

+1 on checking the chain. Also, make sure the derailleur is set-up properly before you go pitching it for a new one.

Unless, of course, this is all just a thinly-veiled excuse to upgrade, in which case... yeah it's probably toast. Time for a new one!

+1 on checking the chain, also. Highest probability is that you've got a stiff link in the chain and as it goes around, it clicks.
Second thing is to check the RD settings. A click could mean that the derailleur is misaligned. Turn the adjuster barrel, either on the shifter, if you have one, or on the rear of the derailleur itself. If you dropped the bike on the drive-side recently, it could also be an indication of bent hanger. Lastly, if the bike is feeling mushy - it flexes a lot, check the chainstays just behind the BB. Step sideways on the crank to see if the right chainstay flexes and shows a crack along the inside. Stop riding the bike if you see a crack. It means the bike is indeed flexing a lot and shortening and lengthening the derailleur cable as you push hard.

Yup, this. My new bike was doing this until I properly adjusted the rear derailleur.

I have a Kona Mahuna and it's great. And it's one of the cheaper ones. Very sturdy. Quality parts on complete bike (avid brakes, sram shifters, maxxis tires.. fsa headset and crank). I'm sure there's something that makes the pricier ones better, but I've never ridden them, so I don't know. But on singletrack, Mahuna is great.

6'4'' and currently **cough** 360 pounds myself (I cough because I was down to 305 not so long ago ) and I have to agree that its very likely a stretched chain though a RD adjustment can also be the culprit (I have had both issues on my K2 mountain bike) I would try adjusting the RD and if that does not work then look into the chain.

You mentioned upgrading to X7, does the bike have SRAM components (shifters/RD) on it now? if its Shimano (and I am not 100% on this but am pretty sure) you may need to stick with a Shimano RD if you have Shimano shifters/RD now.

on the Wahoo, I rode one over the summer (ended up buying the Xcal) and it should be fine.. though don't hold me to that
