In the general section you will see |I have a question on paintshops as I lost the front end at the weekend and down she went.

The cause was me cathing the throttle on the way for the front brake, which I then grabbed too much off. Ham fisted I know. But hey!

Anyway, I find the throttle to be really light, is there anyway of tightening up the resistance as I have caught the throttle a few times and ended up rolling on when I am trying to just use the brake. Does anyone else find this or am I just a bit too clumsy. Any tips appreciated. Bike is a 749s

cheers

Hi Mike. First up, sorry to hear about you dropping your baby - hopefully there isn't too much damage.

Secondly, welcome to the club. I'm sure you'll get plenty of help and amusement out of this place.

I'm not quite sure I understand how you're rolling the throttle on when reaching for the brake? When I reach forward the movement is a natural roll off. What are you actually doing? I don't have one of the later machines and haven't heard of people trying to do this so can't help on that front. Most people want to speed the action up!

I know what you mean Mike. I have a 999 and i found that changing the angle of the brake level helped - also with the comfort factor too.

It seemd to me tha if you have your hand on the throttle grip and especially if you use 4 rather than 2 fingers, as the lever is angled higher than line of your forearm, wrist & outstrectched fingers the tendancy is to have to sink your wrist to get your finers up over the lever, and the heel of your hand will wind the throttle on.

Does that help?

Mike,

You can get a throttle mod, which basically uses the 916/996/998 throttle assembly, the advantages of this are two fold, one the action is a lot quicker, less angle to open the throttle fully, secondly the assembly is heavier, so requires more force to turn the throttle, not as light.

I rode my 999 for 30 miles before I decided I didn't like the throttle, impulse maybe? I had come from several 996/998 bikes. The downside is this mod isn't cheap as it's only using one cable rather than two, and requires quite a bit of work by someone in the know. JHP did mine and never had any issues since.

Bret at Pro Twins was talking to me about something similar. He reckoned it was about 3 hours work for them so it sounds like the same solution. He also said it makes it less jumpy/jerky.

Hi TP
What I think is happening is that my wrists are low, and that I have dragged my fingers up the way before reaching out for the lever. As I have done this I have rolled on. It has happened a couple of times. Bad habit really, in not closing the throttle first by trying just move for the brake in one movement.

Will have a look at these mods

thanks for your help all.

Any one know a good body shop in south London?

Hi Kerry
So did you lower your brake lever, to make you reach over more? Must admit I only ever normally use 2 fingers at the fulcrum, but I think I may have used a few more on the weekend

I have gone a different route - I bought a quick-action throttle kit (see previous thread "quick action throttle #2") and it makes a hell of a difference.

The throttle is a bit heavier - which is great - and obviously its quicker!!!

The Pro-Twins route is one way to go - but @ £200 - I think you can get better for less - mine cost me £150 + 2 hours of my time.

I bought my bike from Pro-Twins and I think they are really helpful - but sometimes (like most Ducati dealers) a little opinionated.

They modify the standard throttle as follows -

install single-cable 916/748 etc throttle
modify the throttle end cams + springs

You loose the safety features of the standard 2 cable setup
It just sounds too complicated to me

They told me that if I didnt modify the throttle end cams and springs it would be too too heavy and that they had spent hours and hours of development on their mod - which is probably OK but I think its flawed - safety wise anyway!

I didnt bother and I think its perfect!!!

and £50 cheaper - if anyone wants the mod done - I will do it - less than 2 hours start to finish - no worries.

Hi Kushy
How do you mean "flawed safetywise" what is the downside?

cheers

Hi Mike,

No changing the angle of the brake lever lined it up with my wrist and outstretched fingers so it negates dragging your fingers up and over the lever. Hence the tendancy pull back on the throttle while reachingover the lever goes.

Having said that I am also going to look at the quick action throttle kit khushy was talking about.
