tire question

this is my first season on a 02 RC. I put 3000 miles on a new set of Dunlop Q2and I have cords showing in the center of the rear tire. Seems early to me.Im not a burnout guy. I do like to ride in a safe swift fasion. What are your thoughts on tire selections. Two other issues a miss about 5700 rpm Its got R1 cans and K&N air filters. Is there a way around a PC. Issue # 2 the engine turns over fine when the kill switch is in the no start mode. but when put in the run mode the engine turnes over hard, and always starts. New starter and new battery didnt help. I spent 7 hours in the saddle on the twisties in NE MO. on Sunday, still trying to get the grin off my face.

Big torque soft tire = low mileage usage. I got 5,000 out of m BT-0016 and was happy...

Is it a "miss" or a hesitation? With the frankenparts of an exhaust I would understand a hesitation (flapper mode done yet??) as there is a dead spot in the midrange on these bikes.

Proper exhaust fitment, custom map and a new rear tire, you should have no issues.

Get the free mods done too if not already (Flapper removal and PAIR removal)

www.rc51.org has instructions.

As for the starter, if the bike starts, no worries. This bike requires a lot of amps to get those monster twins turning.

The miss may be a lean condition at that RPM range.

Mine did it real bad when I first picked it up.
It was so lean that I felt it lose power up to 5800 RPM when it started misfiring.
If I pushed on to 6000 RPM, the misfire went away and full power returned.

It was all caused by the previous owner not mapping it properly or possibly not at all.
After I put it on the dyno and remapped, it ran just perfect.
Even at 16K miles, the plugs looked beautiful when I changed them out.

I got nearly 5000 out of my last Q2 rear tire. I didn't realize it was that much till I thought about here.
I'm pretty quick to leave the intersection too. Getting ready to install my 4th rear Q2. I really like the grip they have for me.

Couple things that help me squeeze that kind of milage; I'm totally nuts about checking air pressure. Before just about every ride. I've found for my weight, +/- 35psi cold works great. I run 15/42 sprockets, so I safely jam out ahead of traffic at a signal, and get the bike moving really quick without having to be hamfisted and apply massive torque to the rear tire.

Checking the tire that often and glancing at the treadwear, also tells me a lot about how I ride.
I tend to be more agressive thru left turns than right ones. I didn't know that. My tire told me.

I got about 1900 miles out of my BT-016's. Have Dunlops ready to go. This is very similar to the mileage I got out of the rear tires (NOT AVONS) on my VFR. Avons Storms could go 4-5K on VFR. Ran 40 rear/ 34front psi, now I'm going to run 42 rear/36 front per manufacturer specs, I just read on Sportrider.com for RC51.

Not necessarily.
Tires wear more on the left in the US and countries where riders travel on the right side of the road.
Tires wear more on the right in the UK and countries where rider ride on the left.
The degree of crowning of the roads determines the amount of wear.
