Remember, the bike picks its speedo reading from the front wheel. So ways that will affect the speedo without getting into the actual assembly, will have to do with the front tire.
If your front wheel gets bigger, your speedo will slow down... Or rather than saying your doing 110, it will now say you're doing 105 at that same exact speed.
If you go with a combination with a smaller than stock diameter, your speedo will say your going even faster than you actually are... Or make the problem with most bike speedo's worse.

With GPS running on my 07 with FMF powerbomb/Q4 muffler, 128 jet, no lid, 13t front sprocket - on level ground top speed is about 75.

I'm going to put the stock sprocket back on and see what that does.

And the speedo reads about 87 so it's way off.

Agreed 210lbs here...Bike runs solid at 73-74...After that its just waiting to go in wobble mod....I also found the tuck works great...I use it going up big hills...Works out good...

Cheapest way will be to buy a 46 or 47 tooth rear sprocket. (You'll need to shorten your chain.)

Speeds...

50-60mph handling's great and all is well.

60-67mph Handling's good but the bike has my serious and undivided attention.

At 70mph I'm 'white knuckling'.

70mph would be fine but it all depends on what road you are riding on. These bikes are terribley succepitble to turbulence from other vehicles on the road. Trucks, SUV's, and tractor trailors are the worst vehicles to be behind. Being behind a tractor trailor is fine until it's about 8 car lengths ahead of you. That's when the turbulence from the vehicle really starts kicking your ****. I'm shocked that any of you can handle this bike at 80-90mph.

The 09 doesn't have a problem w/ the speed wobbles for us. At least my wife all 118 lbs. of her hasn 't complained of any yet. Ask about the time on the xl250r tho...

Hasn't stopped me from looking for a scotts stabilizer for the klx, you never know when some gnarly cross grain is going to hit.
