i noticed that the motor seems to bog out in real low rpm's when just starting out. if i punch it right off the line, it bogs for a sacond, and then pulls. i heard about disabling the air duct over the radiator and gave it a try. if anything, i would say that it lagged more. i just put the hose back on yesterday and really cant tell a difference. is there some kind of problem, or is it just because it is a liter bike and it wants to go, not put?

 

You still running stock exhaust? I can't see disabling the flapper helping much with the stocker. Completely removed mine (pain in the a$$) and it's a noticeable difference. Launching hard on these bikes requires some feathering of the clutch.

 

i have a jardine rt-1 street exhaust slip on. i disabled the hose by simply disconnecting it and putting a plug on the hose, i didnt totally remove it.

 

I guess every bike is a little different. Just plugging the hose helped mine out in the low rpms. Total removal seems to be a little more responsive in the mid-range also. If air happened to get by the plug in the hose then that could cause it to run bad. In the end ya gotta go with what runs best for your bike.

 

i figured it out. i just rode my friends bike with stock exhaust and realized that my jardine was what was causing the problem. i just ordered a power commander today and will report back when i put it on.

 

The power commander should clean up your fuel delivery

 

My 1k did the same thing but then I got the full yosh exhaust and I went down 1 tooth in the front sprocket and now it launches like a champ I love it. I sacrificed 11 on the top end but fugg it I never go 180. I thought it was just my bike.

 

You should recalibrate the throttle position after installing the PCIII. It made a difference with my bike.

 

How do you recalibrate the TPS?

 

You can go on the Powercommander web site and go to the animated tutorials to get a detail explaination. All you have to do is plug into your PCIII, establish connection with the unit (Key on and Switch to run), go to Powercommander tools, select throttle position and click the < Key. Your display will show 0% at idle. Now your throttle is recalibrated. You can do this with the bike on or off. I wanted a true setting so I did it with the bike running.
