SOURCE: The rear sprocket has noticable side to side play.

It should be not too tight but it sounds, as your chain is more than the required three loops check the chain and see how much you have extra links?

More power from tc 250 2010

Top end engine rebuild. Sprocket size depends on the type of riding. Standard should be OK for motocross. If you need more top speed install a larger front sprocket and a smaller rear sprocket. Divide the rear sprocket teeth by the number of teeth on front sprocket e.g 48/14 = 3.43 a lower number means higher top speed 45/15 = 3.0 but compromised performance at lower speed. For tight forest riding and steep hills Rear 48 front 13 = 3.69 etc is preferable.

Can you change tranny gears to decrease rpm's on highway? Or maybe change sprockets.

You can add teeth to the front sprocket or take teeth off of the rear sprocket. In the case of your bike , I do not think there is a 17 tooth front available so your best option would be to shorten your chain and drop from the 44 tooth rear sprocket to 40 tooth or a 36 tooth rear sprocket. That would be like adding one or two teeth to the front sprocket. Your stock is 16/44 so decrease from there. Be sure to ID your chain, get a chain breaker, and a new master link.

07 YZ450F First gear is to tall but then it peaks out to soon along the long trail,wil changing the rear sprocket down a tooth help ?

Find out what the tooth count on the rear sprocket was from the factory and see if you have a smaller sprocket than stock. THIS WILL BE FOR A FASTER TOP END.
a larger sprocket will give more power /rpm less speed.

Chain tension

Usually you want about 1 -1.6 inches (35-40 mm) from the bottom of the chain to the bottom of the chain when you grab the bottom chain about halfway between the rear sprocket and the front sprocket and move up and down.You should also left the rear wheel off the ground and rotate the chain around both sprockets checking the slack at all points of the chain. If while rotating wheel the chain gets tighter or looser this is a sign that your chain has stretched in one short section and should be replaced. If left on the bike it will either wear out the sprockets a lot faster than normal rate or the chain could break possibly damaging the engine case (very expensive).

How to increase top end speed - 2007 Kawasaki Ninja EX250R

you can change the sprockets.If you go to a 16 tooth front sprocket. two teeth on a front sprocket is like droping 4 teeth on the rear. You could drop 2 teeth on the rear sprocket but a 43 tooth is probably harder to find. the usual choices for front are 14,15,16 tooth.
For the rear they are 44,45,46 tooth

The way to remeber gearing changes is on REAR sprocket is smaller=faster and larger=slower top end.
the FRONT is OPPOSITE to the rear smaller=slower and bigger=faster.
You may have to lengthen or shorten the chain depending whjch way you go.

Sir, I own a Passion plus Bike 1996 make. 1.What would be the reason If I experience chain sounds-Usually while changing gears? 2.some sort of Shaking Rings noise from Engine , was it really mean that the...

The transmission consists chain sprocket assembly, with the smaller sprocket on the engine & a larger one at the rear wheel. The chain stretches and the sprocket teeh keeps getting worn whenever you accellerate or use the engine as a brake to slow down. This play can increase up to 2 inch,. thus on lower gear, higher mechanical advantage, looses since the sprocket of the engine transfers power after that play/gap/time required to tranfer the same power to the rear sprocket result of metal on metal hammer.
Tighten chain at regular intervals and change the chain sprocket if its still the original one. If the bike runs 50+ km in a day and/or at high speed, change the engine oil every 500 to 750 km running i.e. once a month. Whichever comes first. The oil becomes darker & looses it's viscocity(thin). Also after covering so many kms, if the engine oil had been low for that period & running at a good speed you might require a change of piston rings( 1 oversize) and then filed to fit without jamming the piston.........sodeep
