I'm riding a r106.my trottle seems to have problem.when I'm traveling at constant speed.out of a sudden there seems to be no acceleration when I throttle and suddenly it come back again after awhile,sometimes when it happens and I pull in my clutch,the engine dies off.what's wrong with it?I just did a valve clearance and clearing of throttle body.

You may have a fuel restriction. If it has a fuel filter remove it and blow through it. If there is any more than slight resistance, replace the filter and try again.

Does it down shift appropriately when accelerating? Normally when you stomp on the gas while in a high gear (travelling at 40mph), the transmission will downshift to a lower gear giving the car much more torque. This can cause the car to jolt or jerk forward and accelerate suddenly.



If this is way off base and you\'re experiencing something else, please let me know

Acceleration is defined as a change in speed, either a negative acceleration (slowing down) or a positive acceleration (speeding up). If you have constant speed, you are not accelerating.---------------------------------------------------------------------------------------

Hi,

Sounds like you need to tune your carburetor and check the spark plug.
Try checking the CDi, replace it with an aftermarket racing CDi and compare the ignition and combustion, if it still doing that problem.

Tell us afterwards to guide you more of these problems.

it sounds exactly like a cv (constant velocity) joint. it transfers power from the transmission to the wheels. Should not be a steering part. have this fixed soon - it will get worse.

First part: start from rest, this means V0=0, d0=0
The motion equation
d=(1/2)*a*t^2+V0*t+d0
simplifies to
d=(1/2)*a*t^2

With d=0.25 mile or 0.25x1600m or 400m (because 1 mile=1600m) and t=19.9s
d=(1/2)*a*t^2
or
a=2*d/t^2
a=2*400/19.9^2
a=2 m/s2

Second part: Come to a stop.
For constant acceleration from start or decelaration to stop, use this formula
v^2=2*a*d
or
a=v^2/(2*d)
a>0 for acceleration and a
Substituting v=60 mi/h or 60*1600/3600 m/s or 26.67 m/s (because 1 mile=1600m and 1hour=3600 sec)
and d=146 ft or 146/3.3 m or 44.24m (because 1 foot = 1/3.3 m),
we have
a=-26.67^2/(2*44.24)
a=-8 m/s2 (deceleration, a

Because v=at, the time it will take to stop is
t=v/a
t=44.24/8
t=5.5 s.

heve utried adjusting the trottle , just put your foot on the accelerater and hold at just under 1000 revs if shaking goes then thats your problem should idle at just under 1000rpm
