Will be interested to see your replies to this as im having similar problem. My throttle isn't heavy , its just developed cruise control. Checked cables , springs etc and all seem fine. Just seems when all connected up something along the way has gone tight. Ive ordered a new set of cables just incase something inside is catching when routed from throttle to carbs. Only thing I can think off.
Just seen vid and yep very similar to mine. Only thing I can see there is yours sit slightly higher than mine at throttle entry. And now not too sure if I should cancel new cables as by your pics you have fairly new cables on there. Will have to see if any ideas come up with solution.
Have you checked your routing against the diagrams in section 2 of the manual (downloadable here)?
Make sure your bar ends aren't touching and restricting the movement on the handle grips.
Wee question regarding routing of cables. I ve seen diagrams of routing throttle cables, but in pics of bikes I see that some are above brake lever and some below. So , what is the right way, above or below lever ? Mine are below just cause it seems neater , although above gives less of a curve to cables. This does not help with [font=] vladgluhovhere problem , but may help when he gets back to fitting them back on the bike.[/font]
Is it friction at the twistgrip itself?You may have the rubber grip rubbing against the body of the pulley housing, or the bar end weight pressing on the outer end of the grip.
You're saying you still have the problem with the carbs out and no tension on the cable? I'd try putting the old cable back in and see does the problem go away. If it does then the new cable is at fault. If it doesn't there must be something wrong in the carbs or you have two faulty cables which seems unlikely. Did you have this problem before you did your work? If not then you know the old cable is good so if there's still a problem when you put the old cable in there must be something wrong in the carbs
The butterflies aren’t lubricated by fuel, the float bowls being empty won’t have any effect.I put a drop of oil as near as possible to each bearing point on the pivot shaft, but if the bank of butterflies turn smoothly and snap back OK when the cables aren’t there that doesn’t sound like the cause.Silly suggestion: have you checked the right cables are on front and back of the carb pulley?Only asking because the old cable I have to hand has the chunky adjuster on the return side and your photo shows it mounted on the front.

Is the problem there when no cable is attached? Do the butterfly valves snap back normally when no throttle cable is attached?
