I have had my 01 Raptor for over a year now, and ran the absolute **** out of it. Never had a single major problem. Went riding on Sat. and only in 2nd gear it feels like a chain jumping teeth on a sprocket. It will pop a few time through 2nd gear. It does it pretty consistently in 2nd gear only. The other gears are fine, and the bike ran fine other than that. Did I lose teeth off the 2nd gear? Anyone have an idea what happened? I planned on tearing it down for a cam, piston, ported head install anyways this winter. If it is the tranny then should I go with the Fortin gears, or the 02 gears? Whos the best to get the parts from? Help!

 

It sounds like you rounded off the 2nd gear dogs[img]i/expressions/face-icon-small-frown.gif[/img][img]i/expressions/face-icon-small-disgusted.gif[/img]

Go with the 02 gear set. It's cheaper than a fortin 2nd gear & the ratios are better.

 

Yep, what MOOSE said! I did the same thing on a 400ex, just rounded the dogs on second gear. Had to replace the mating gear as well.

 

yep that what happ 2nd gaer dogs are rounded

 

I did miss 2nd gear many many times with the stock shifter while getting after it real hard in the sand drag racing. After I put the ProDesign on I've maybe missed it 2 times. So go with the 02 gears huh? I do like how the 02s gears are setup. Anything else to replace while in there? One way starter bearing, or oil pump gear? Sounds like those can fail pretty often also. I will be doing a piston, cam, bored, ported head while it's apart. Any other tips guys? I'm in KC and there's no local shops that I know of other than the dealers(and they are not touching my bike). I will probably do all the labor myself except porting the head, valve job, and boring cylinder.

 

If it was me, I would probably update the one-way starter parts too; good idea. Mine went while I was riding, kind of sucks. If you replace them, you would have a spare (old one) for when it goes out on the trail![img]i/expressions/face-icon-small-wink.gif[/img]

 

Have any of you tried moddifying the shift star? I did this on my banshee and haven't missed a shift since.

 

i rounded the 2nd gear on a mojave and a warrior is it that that is the gear i am in alot

 

hey--- if you have never seen the "dogs", what we are all talking about--go to www.bikebandit.com and look up the factory gearson an 01 and then an 02. 4 dogs on the 02 and only 3 on the 01. yep, you'll have to replace the mating gear and quite possibly- check out the reverse gear too. id only stick to replacing those gears cause if you did the whole 02 setup, it'd be around $1500[img]i/expressions/face-icon-small-frown.gif[/img]

forget the 01's before tranny update, its like driving a porsche with a rock bouncing around inside the tranny!

 

Are you sure it's the tranny? Mine skipped the other day in 2nd gear, and I noticed the front sprocket teeth were worn down pretty badly. I am waiting for my new 12 tooth sprocket to arrive any day now. Hopefully it's the sprocket.
