thousand dollar budget on your 10R
1. Yoshi slio-ons: (excellent build quality & not as loud as most others. LOUD gets old very fast !!)
Skip the power commander. You don't need it with slip-ons.
2. driven block off (smog) plates: This mod will take you a couple hours on your model 10R. You might consider changing the plugs at this time also since you have some of the bike apart. cost less than fifty bucks
Buy them at kneedraggers or many other websites.
3. Pazzo or ASV adjustable levers: Most riders get the shortie ones. I think if I bought another set, I would buy the the long version ASV from motomummy.com. $225.00 for the ASVs
4. do the sprocket change:
-1,+2 is too much for the 10r. Go with zero, +2 or zer0, +3. buy from sprocketcenter.com. Call them and talk to them.
Do not buy the silver aluminum Vortex rear sprocket. It will only last you 3,000 miles. It costs less because it's not hardened.
The rifleman't quick turn throttle mod is great if you spend a lot of time at full throttle. Otherwise it makes the bike too jumpy if you want to be smooth when cornering. Leave the secondary throttle plates in unless you are going drag racing with very low gears.
***get the suspension adjusted for you. you can prob find a private mechanic or x-racer on one of your local sortbike forums. This will help out your handling immensely. This service should cost you fifty bucks.
Put in some seat time before you challenge your gixxer buddy to any friendly contests. with literbikes it's all about the rider, not so much the bike. Welcome to the addiction.
If you are into riding the twisties heavily, I would forgo all the above mods and just buy a Pensky Shock. Have the suspension set for you. You will have the capability to outrun your gixxer buddy in the corners, but he will accelerate a little quicker. Suspension mods are usually the last mod a rider does, but they will make the most difference in brisk street riding and trackdays.
