main disapointment with GTR
« on: May 14, 2018, 01:59:02 PM »

My main disappointment with my GTR is the low down torque or lack of it I should say .
I have noticed that unless I am spot on with gear selection going around corners and I have to slow down for some reason , it shakes like a good un if I am in 2nd and it feels like I should be in 1st for instance .
If it had more torque I have a feeling it would just pick and accelerate through the corner even in 2nd .
Maybe it's just me and my lack of riding ability .
I have read the GSXR 6 is the same where as the GSXR 750 is more forgiving with gear selection .
Anybody else have any views on this because I think this should be a serious discussion rather than just slagging me off for being a shite rider  :o .
I am the first to admit I am no Valentino Rossi and I am far , far from it in fact .
Another thing , are all 600 or 700 bikes as gutless in 1st as these are ? When I hit 2nd it accelerates like a rocket but 1st seems like a waste of time  8) .

Is the kinda jitter at say 2k rpm 2nd gear going around a roundabout slowly type thing ???

I've noticed at least on my bike at the moment, low rpm/low speed is very twitchy with the throttle.

It seems like a lack of torque low down .
Get the revs right up and it's fine but let the revs drop just a bit , say in second around a 90 corner and hang because it will try to shake you off the bike .
It's not always a good idea to change down to first either risk of locking up the back wheel  :o
It's probably just me being a shit rider but there go .
Can't remember having problems like this with other bikes .

To spite being a v-twin, it's not a high torque output engine.

It is originally designed to be:
A commuter bike, as in the GT.
Able to use low octane fuel.
Cheap.

It's the ignition timing that hurts it the most. If you advance the timing, you will get loads more grunt, however when using low octane fuel, it might ping.

If you don't mind using E10, or premium fuel (E10 is good enough), then you can get an ignition advance "kit" which is just an offset woodruff key from Factory Pro. Beware, they know how to charge! It's about $140 + p/h to Australia.

http://www.factorypro.com/Install_pages/Install,RTR,Suz,SV650,DL,TL,ignition_advance.htm

It's designed for the SV650, but fits.

Gives an extra 4 degrees of ignition advance.

Ohh and make sure the throttle body sync is correct.

Try going down 1 tooth on the front sprocket.

I agree with this bit of info. I've never had a problem with lack of torque.

It'll give you a bit more "Jump" out of the corners.  You'll lose top end though.  Down by about 5mph.

Go here ... I was the first one to try the 14 tooth sprocket and I put the data into Gear Commander

https://www.gearingcommander.com/

Going down one tooth increases the revs for a given speed for a given gear. This puts the motor further into the power band keeps the motor "On Cam". 

BTW ...Best way to get more speed... Lose weight and do a track day.  The Hyosung will keep up (and better) the other 650/750 V twins on the track and will put up a good fight with most 600/4's.  I got accused of have a 1000cc motor by a guy on an SP2 once.  He was told "It's not the bike mate ...it's the rider"

That sounds like a very good idea, thanks
So I need a 14 tooth front sprocket?
