Throttle twist grip

[mrTickle]

I've just done 250 miles on my new Adventure and decided to give it it's first real blast of full throttle for about 200 yards so the cylinders don't glaze up. I was surprised at how much the throttle needs twisting 'round for full acceleration - I am not used to having an accelerator that needs so much twisting.

Does anyone know how to reduce the amount of twist the throttle requires? Someone I met told me that an "enduro" version of the throttle is available for the GS series. Supposedly it halves the amount that you need to twist the throttle grip. Anybody know anything about it or how to shorten the length of the accelerator twist grip?

I do,but I'm not telling you Leave it with me for a day or two and I'll see if I can make you a do dah thingy like what you want. I'd do a lot more than 250miles before opening it up like that as well

I just knew you'd have the answer. I've been wondering about this for quite a while, together with decreasing the spring tension so that I don't need 3 shredded wheat before going on a longish ride.

Didn't realise how long winded the GS throttle is til I had a go of a mate's blackbird recently (fast but not really my cup of tea) a quicker twistgrip would be of interest to me,keep us posted Vern

I decided to give my bike a quick short blast, to deglaze the bores. Don't know if this is an urban myth but I do know that the only bike ( Guzzi 1100 sport ) I ran in exactly according to the manual, blew the its' engine -TWICE!

I've owned about 15 brand new bikes ( I think ), and most of them I have run in using this quick short blast method. They all seemed to go really well after the break in period. I must add, I have never kept a bike longer than 3 years so don't know how the long term effects of breaking in an engine like this goes.

I did find this site:

Makes for some interesting theory. When I had a brand new KDX a few years ago, it only needed a few miles to run it in according to the Kawasaki manual. The rings are changed more frequently on a 2 stroke like this, so maybe the run in period just beds the rings in? It's too late for me to follow this method now, as I have around 300 miles on my clocks.

Anyway, getting back to my original question about the twist grip, most of the other bikes I've owned - no make that all of them - all have a shorter twist on the grip. Most were also far more powerful. It's almost as though BMW have made this twist soooo long, to stop inexperienced riders getting into too much trouble by giving it a handful. Let us onto your secret Vern and we shall be forever in your debt

Good idea, but making the throttle action quicker would make it heavier as well wouldn't it? Or can you change the return spring on the throttle body?
