Is there any lighter tension springs that make them easier to push?

 

Is it harder than the oem throttle carbs? I didnt feel any difference on mine. Call Sparks racing and ask them about it. Thats where I got mine from and they are like stock.

 

They are significantly stiffer than stock. It's about like a Banshee with PWK 35's.[img]i/expressions/face-icon-small-shocked.gif[/img]

 

It aint nothing like the Lectron, I need a spot to ride..But hey i got the buffest thumb on the block..[img]i/expressions/face-icon-small-disgusted.gif[/img]

 

1Bad doesn't a lectron have a spring above the slide like a stock carb? If it does you could take a coil or two off until it was where you liked it. The FCR's have a spring on the throttle shaft.[img]i/expressions/face-icon-small-frown.gif[/img]

 

lowbowtie,
I got my carbs from Sparks, when they just started to offer the 690 kit to the public, I contacted them about the throttle spring and Scott sent me a lighter spring than what was on my carbs., Give Sparks a call and ask him about the spring. If they dont offer it anymore, I have the lighter spring that I could ship to you. I went to a twist throttle, so I did not have to use the lighter spring.

herbdon.....

 

herbdon, I am waiting for a call back from Scott as I type this. I'll let ya know how it goes.

 

LOWBOWTIE - YOU WILL WAIT FOREVER!! Just call him back in an hour and an hour after that. I have not met a single soul where Scott has called anyone. Believe me if he does please post it because this will be the first!!![img]i/expressions/face-icon-small-wink.gif[/img]

 

You may be right. I have not heard from him yet. And Scott said it would be about 30 mins when he called back. I know its just a spring but If that's the case then they Suck!

 

LOL!!! very true!!!

yeah the 39 fcr's have an extrememly stiff spring!!! i use a twist throttle so it doesn't bother me at all but when i had the thumb throttle it was unbearable especially duning!
