Sprocket change for the track?

I was doing really good in my corners, and one session I got stuck behind someone that was taking them at a snails pace. You can't pass in the corners as a novice, but I couldn't pass him on the straights even though he was on a 600 like me (really me off and ruined that session). I talked to an advanced guy and he recommended I either go down a tooth in the front, or up three in the rear. Is this something advisable to do now, or should I wait until I have some more track days under my belt?

Another question I have is how this is going to effect my top speed. I was only able to get the bike to about 135 on the front straight at TWS (Texas World Speedway) before I ran into turn 1. Will the quicker acceleration help me go faster, or will the sprocket change make me top out at that speed?

I think now would be fine. It will give you some street time to get the feel for the change. Try -1 in front. If you want more go +2 in the rear. Most people recommend a new chain with the sprocket change. As long as you dont need to go faster than 145 ish you would be really happy with -1 and +2. You will run 9000 prm on the frwy at around 80 mph. Your speedo will also read 15 mph faster. This will clock more milage than actual. A speedohealer will correct it though.

You will get to the top faster. It will probably take about 15 off the top at -1+2.

I use to have -1/+2 on the r6, now I am at -1/stock and I like it much better. I think it really all depends on you, your bike, and your riding style though.

I didn't worry about any performance mods until I had several track days under my belt. My guess is that if you had a better line and better drive out of turn 15 (or any turn for that matter) you could have passed that guy.

But if you insist, -1 is a good place to start.

-1 in the front will give you more low end speed (torque) which will be plenty for now. I doubt youll notice you top end, unless your going 160 down the front staright at TWS (Texas World Speedway).


Next time just pull through pit lane if you can pass em

-1 in the front is equal to +2.6 on the rear. Starting at -1 is a great place to start. If you do this I would highly suggest a speado healer. This will make your MPH correct, and keep you from putting "ghost miles" on the bike for resale.

I was told to pass only on the straights and was trying to be careful. It really was all I could do to stay out of his tailpipe in the turns though.

And I am unsure which one was turn 15, but if it was the last turn, it was our last lap so we had to pull into the pits.

+100000 on SpeedoHealer. $100 and well worth it.

Spend the money on track time. When you're starting out, thats your best investment. I understand wanting everything to be right, having your bike set-up perfect, BUT...

Lets say you get the gearing spot-on for your CURRENT skill/speed and for TWS (Texas World Speedway). Next time you go out, YOU'RE GOING TO BE FASTER, WHICH THROWS YOUR WHOLE "PERFECT GEARING" OUT THE WINDOW. Or go to another track, and its sure to be off.

ALSO, mount a video camera if you have one. You can see where you're at on the tach... maybe you're at 9K RPM and you just need to go through that corner in 2nd instead of 3rd.

I agree. If the guys is moving at a snails pace then you should have no prob taking him using the correct line with the bike as-is. Taking the right line will give you a much better exit speed than someone freeways bombing the straights and parking it in the turns.

This helped me out when i was having the same prob with a guy on a gsxr750
Question: How much is the gearing gonna help you when the guy is on a bigger displacement bike?

Take a better line through 13, 14 and 15 then get enough drive to pass him on the front straight....then he will pass you back...then out brake him into turn 1.

Problem solved.

Or sell your zzr and put money into a different bike.

+1 no need in dumping any money in yet. Why not jump up to int. next time and see how that goes. There will be slow people in everygroup, but the pace is definately quicker. Also use the hot pit when you get stuck behind someone. If you were riding his , chances are you were starting to get frustrated and fall into his lines, and make his mistakes. Pit out for a minute then youll be good to go.

If this only happened once and it was on the last lap or even just occassionally, the best thing you can do is get more track track experience.

After ensuring the bike is solid from a safety perspective, upgrade the rider and then upgrade the bike.


You'd be shocked at what an intermediate rider could do on your bike in terms of speed, braking, and lap times.
