Missing teeth

[PharmerKyle]

How bad is it to be missing 17 out of 41 teeth (non-consecutive) on a rear sprocket?

Follow up: How lucky should I feel to still have a chain and my left leg intact?

If it never fell off, you're golden. Having your chain fall off on the freeway is inconvienient. :D

I'd say you're almost due for a replacement, though.

[PharmerKyle]

Check!

I'll see to it before springtime:)

lol I had 13 missing and was good to go :)

Thanks again rybo!!!!

If you already have almost half gone, the rest will be gone before long. You might want to replace the sprockets before spring if you are going to be doing much riding at all this winter.

[Fly boy]

I was told that you want to replace BOTH sprockets at the same time, and its a really good idea to do both chain and sprocket together.

[swademaster]

It is best to do all three at the same time.

I thought this was going to be a redneck thread :down:

I didn't shave off any teeth on my rear sprocket but they were so worn that it felt like my tranny was mis-shifting! I normally don't worry about the front sprocket as it is steel. The chain and rear sprocket is what I normally change out. But definitely if you are missing teeth already, get a new sprocket at least!

Replacing all 3 at once isn't always necessary. There are all sorts of measurements that can be taken to determine exactly what needs to be replaced. FSM's will give you exact specs. Depending on riding style/care and feeding of the machine you might just need a rear sprocket.

But if you aren't strapped for cash and are doing the work anyway. Spend the money on a nice lightweight chain/sprocket setup and be done with it (assuming you already haven't).

if it is so worn that you are missing that many teeth on one sprocket, replace all 3 and save yourself the chance to do your motor later. If you only replace the rear, you run the risk of your chain not meshing with the new (complete) sprocket and skipping a tooth or something. All those parts together should be less than $200, and I would hit up Joe Logalbo (jplracing) and have him get your prices on the stuff (will save you $$ over a dealership fo sho).

[PharmerKyle]

I plan on all 3 at once. No orders have been placed just yet.

I'm still weighing some completely absurd options with regards to the 750's future. Selling it outright or converting it to an ADV-tourer are at the top of the list. The future of the PMI track and the cost of other parts will be the "decider".

Now THAT'S funny - ur killin me doood.

Just keep in mind that when you replace it don't go nutty right away with the bike. Take it easy on it till the chain and sprocket(s) set in...not sure how many miles you gotta go before that happens though.

Pretty sure Pharm won't be seeing 170 mph anytime soon, after all he is a family man. I sure would be interested in your recommendations for tire and brake pad run in though.:bow:

The only way I'd get to 170 is with gravity's assistance. Even then it would have to be a pretty tall cliff.

FSM's will give you exact specs.

I've been praying to the FSM (Flying Spaghetti Monster) all week and still have no exact data. I think I need to cave in and just buy the stuff.

Pharm,

I'm going to disagree with the post above about going with the lightweight setup, get steel sprockets front and rear, they will last much longer, especially if you are thinking of doing any kind of distance riding on it.

The future of PMI is looking pretty bright, the city council in Pueblo has all but confirmed that it's not going anywhere soon and that they wish to make improvements to the facility, just not all at once :)

In the "other good news" category, there are two tracks that are well into their proposal process. One has a land deal, money and no permit. The other has a land deal and a permit, but not enough money. Both proposed sites are within a couple hours of Denver.

[PharmerKyle]

Good!

Now I don't feel like my prayers to the FSM have been in vain.

I dunno RYBO...going with the lightweight sprockets will save like 2-3 pounds...take off your mirrors and license plate to reduce drag. Remove rear brake set up (we have determined those as dangerous now days) and gauges to save more weight, maybe the plastics too....you could probably hit like 172 :D
