Topic: Is there a quicker throttle for the 550?

[anparkinson]

My only complaint with my 550K3 is the amount of twist the throttle needs from closed to fully open - more that I can manage in one movement so I almost have to let go and grab it again.

Is there any quick mod or kit out there that can give me a faster throttle. I would imagine a new slightly longer cable would be necessary if the diameter of the cable run is increased but I'm open to any ideas.

[strynboen]

can you make a shorter arm on kaburettors,,or drill a hole in that arm,,for a nev direktion..shorter vay,,,

[Gorms]

Or find a thottle tube with a larger diameter pulley wheel.  Might not be able to use the stock right hand control though (?).

 a larger pulley will not fit in the stock throttle housing IMHO

euro racing have the best solution, it has different pulley diameters so you can find what suits you best.

You'll have ot find another solution for the starter button anr lights control and its expensive too.

be warned, quicker throttle means also heavier effort to overcome spring tension.

Look in the FAQ under "Thoughts of Hondaman".  In his section for the 550 he describes how to modify the stock throttle sleeve for this exact purpose.

This is what I did on my project bike:

I had my Dad make up a little cam to slide over the throttle tube to quicken up the ratio of the twist a little bit.



I had to do just a little bit of clearance-ing out of the housing for the cam to fit.

I was going to measure the amount of the twist before I put it in, but I forgot. It does twist a lot less now, though. It has about the same amount of twist as my Ducati does.

 I got a shorter turn throttle housing/tube from somewhere...but yeah you can't use the factory right switch assembly. I'm just using a single starter button though on that side...no need for the whole switch assembly....

Motion Pro maybe is where I got it?!

nice trick, used it too on my guzzis too, but if you want a REAL quick throttle,i.e. in the 90-100 degree to WOT range, you really need a much bigger pulley AND housing.

Replace it with a super fast super trick japanese Takuro billet throttle from www.discovolantemoto.co.uk

http://www.discovolantemoto.co.uk/handlebars-controls/takuro-throttle-assembly/prod_610.html

I use these on both of my bikes now - they are the dogs danglies and being race throttles use aroudn only a quarter turn.

Ok this has GOT to stop...Mr. Lordmoonpie...if you post anymore links of expensive awesome things I want...my credit score is gonna hit rock bottom...again lol.

That will get your front tire in the air and make you think twice before calling the 750 "not a sportbike". 

When these types of 1/4 turn throttles appeared in the early 1970s for the 750 (with both cables, they are out there, somewhere...) we could not get enough of them. The local riders called them the "wheelie grip" throttles when they came in asking for them. We just drilled a new hole in the handlebars to accept the stock right switch about 3/4 inch further in, then added the new twistgrip on to the bar end. The front brake lever then seemed a bit of a reach, so we adjusted the levers back toward the bar. (The brake lever adjuster, BTW, disappeared on the K2 model, being replaced with a piece of bumper rubber, instead.  )

I'm really offended now!

At 200 euros, wasn't the one I posted expensive enough?

Just dont get it....

becasue its not a push-pull throttle, you dont want a pull only on a four pot bike for safety reasons.

That specific one is for a mini-bike. It will be undersized and not up to the job.  I have run single pull throttles on CB750 before. There is the school that cautions against for safety reasons, and they have their point. Then there are those....  

But if you were to do it, you'd want something for a big boys bike and that would cost closer to $50+ like these Tommaselli models: http://guzzino.stores.yahoo.net/collectibles.html

Or this magura dirt bike model looks interesting at $25 also. 2 speeds: http://www.huskyclub.com/magura.htm

Scroll down.
May be undersized however.

 At least,there is other option than the model at 200 euros

You know....

About a year ago, there was a thread on quick throttles in which I participated...

And I disclosed that i owned 3 of those Commado Rapidos...

And I was willing to sell at least 1 maybe 2 for $35US...

And for which i had no takers....

And now that the 200Euros has surfaced...

I won'r sell at all!

dont "worry", on my bike i use a cagiva-ducati throttle found in a swapmeet for 10$..... gave a very good rate with my 26 VM's but was too quick for the new 29 CR's, put back in there a stock 500 inner sleeve now.

[Ecosse]

anyone know if other bikes from the same era had a better throttle to use on the sohc? or are they all wrist killers?

did you have to glue the spacer on or is it just resting there? i'm going to try that on my k4, not so much for the fatser throttle but anything i can do to reduce the distance i have to turn the throttle to WFO is a good thing

well that's funny you say this.. i got questioned about doing this on the freeway last Thursday.  my buddy watched my creep all my fingers up the throttle slowly while accelerating. he said it was kinda creepy to see. and i do it so often i just don't notice it anymore.

  now I'm not one to race my 550, but man it almost kills my wrist not moving my hand up on the throttle on long rides

[Ecosse]

i hear ya. i bought what i call football grips (thicker in the middle) in part to save my nancy boy wrist from unspeakable pain. a quicker throttle would also be dandy.

[lordmoonpie]

Disco Volante have some cheaper throttles too with push pull - some bery nice gear on their site. I love that Takura throttle though - it's like silk, well worth raiding the wife's purse for some of those crinkly bits of paper for 

Hey Colin - didn't they invent credit cards just so we CAN buy this stuff? 

[westondc]

my bike came with touring style grips on it. they're wider than stock and the throttle grip has a large lip on it that the palm of my hand can rest on for leverage. it works great. i can push on the lip area with my thumb for full throttle without repositioning my hand. also helps with overcomming return from the throttle spring. this type of grip might help you and with little modification. cant seem to find a good example of this style grip on the internet.

I am so going to do this today! Great idea. I did the wire in the cam groove, but it didnt seem to do much.
thanks,jim

SNIP
crap! 

 

Nice thing about the Commando Rapido is it hooks into the original switch gear, It sounds like Hondaman was installing it or something similar by sliding the switchgear in a little, drilling a new locating hole, then install the throttle. it looks like stock.

[turboguzzi]

Oh yeah, Takuro, does it have changeable pulleys?

 take that!
