During my ride around today, my saddlebags kept inching forward. To remedy this, I moved my Tour Master saddlebags under the rear seat. Getting it under there was easy, but to put the seat back on was a real pain. It took a lot of forward pressure to get all the holes aligned, but the result should work better.
Well, I got the rear turn signals moved today. It appears to be working well. I will have a more detailed description of how I did this, but wanted to put a quick couple of pics up. I made an extension cable (19.5 in) that uses the Suzuki OEM connector, so I can try it out and if I don’t like it the procedure can be reversed VERY easily.
I know that there are many how-to’s out there, but I wanted to document how I installed my new 16 tooth front sprocket for my 2009 Suzuki TU250. As I am very much not mechanically inclined, I wanted this to be as moron friendly as I could. Hopefully this will be a help for others out there, and will be a good refresher for me in the event that I have to do this again.
Tools needed:
Torque wrench
30mm socket
7mm socket
17mm wrench
19mm wrench
12mm wrench
Step 1: Remove the front sprocket cover using the 7mm socket. There are three bolts that hold in the cover, shown below.
This shows the location of the three 7mm bolts that hold the front sprocket cover in place.
The three 7mm Bolts; Top, Middle, and Bottom
Step 2: Flatten the lock washer tabs that holds the 30mm nut in place.
Step 3: Remove the 30mm nut, using the wrench and socket.
The brick next to the tire keeps the bike from moving. A wheel chock would be better.
Step 4: Move the rear wheel forward, using the chain adjustment.
Loosen the rear axle nut using the 17mm and 19 mm wrenches.
17mm on Left, 19mm on Right.
Once the rear axle is loose, the chain adjustment screws can be loosened to allow the rear wheel to move forward.
Step 5: Once the rear wheel is moved forward, the old front sprocket can then be removed and replaced with the new sprocket. Once the new sprocket is in, tighten the 30mm nut so it is secure. Reverse the above procedures to tighten the chain back to its recommended setting (10-20mm), then tighten the 30mm nut to 65ft/lb of torque, placing the wheel chock on the rear of the rear tire to keep the bike from getting away.
Make sure to re-bend the washer tab AFTER tightening the 30mm nut to the appropriate torque.
My mark for chain tightness moved inward slightly (which to be expected with a larger front sprocket).
Step 7: Re-install the front sprocket cover. Project completed!
I have ridden for about a week now with the new sprocket. These are my findings:
1) Performance in heavy head winds is similar to the original. I normally need to shift into third gear to keep at highway speed (20-30 knot wind). In no-wind conditions, there is a slight improvement, allowing me to stay at 65-68 mph in fourth gear, 60 – 62 mph in fifth gear.
2) The first three gears have a marked improvement in performance for city travel. The torque of the TU’s engine is very nice in these gears and makes for a very fun runabout.
3) Fuel mileage appears to be similar, but since I have ridden only 200 miles so far, I cannot state this as fact just yet.
If anyone has any questions or if there is something missing/erroneous in this post, please let me know so I can correct it.
