When i put my bike on sixth gear(top gear)the speed only can perform 120 km/h...i just finosh top overhauled with changed 8 exht valves and 2 intake valve..during on sixth gear,my bike very difficult to speed..only max can go 120km/h..help me.....

their are 16 models for the anglia in 1966 using the higher hp /manual set up --Anglia 105E-123E Saloon model for Europe North America , 2-door sedan with manual 4-speed and 1198 cm3 / 35 40kW (47 54 hp / 48 54 PS);--------- Acceleration:0-30 km/h (s):2.20-40 km/h (s):3.50-50 km/h (s):4.60-60 km/h (s):6.60-70 km/h (s):8.50-80 km/h (s):10.90-90 km/h (s):140-100 km/h (s):18.50-110 km/h (s)24.40-120 km/h (s):34.7----------Drag times:0- 1/4mile (s):20.4speed at 1/4mile:103 km/h / 64 mph0- 1km (s):38.9------- Top speed: 132 km/h / 82 mph http://www.automobile-catalog.com/auta_perf1.php

Most likely a bad catalytic converter will trigger this symptom, especially if your find you have to push more on the gas pedal to maintain hiway speed. One other possible problem can be a bad/dirty fuel injector pouring an excessive amount of gas into the cylinder(s). Get your self a couple of bottles of chevron techron concentrate and put it into the gas tank fill it up and let the tank run to almost 1/8 full before you refill this will aid in cleaning the injectors.

A lot of the newer vehicles have speed sensors, do you get any codes.?

DTC P0736 - Reverse incorrect gear ratio

The clutch pressure control (PC) solenoid 2 flows fluid to the 3-5-R clutch when commanded OFF and exhausts fluid when commanded ON. The clutch PC solenoid 2 regulates the transmission fluid pressure to the 3-5-R clutch. The transmission fluid pressure (TFP) switch 1 Opens (High) under fluid pressure and closes (Low) when no pressure is present. The transmission control module (TCM) calculates gear ratio based on data from the automatic transmission input speed sensor (ISS) and the output speed sensor (OSS). The TCM compares the known transmission gear ratio to a calculated gear ratio for each commanded gear.

Circuit/System Verification:
Operate the vehicle to induce a shift from second to third gear while observing TFP Switch 1. Perform this action 2 times. The TFP Switch 1 should change states from Low to High. If the TFP Switch does not change states and no other DTCs set, replace the control solenoid (w/body and TCM) valve assembly. If any other DTCs set, diagnose that DTC first.
Operate the vehicle to obtain sixth gear 2 times and then check for DTCs other than DTC P0736.If any other DTCs set, diagnose that DTC first. If no other DTC sets, continue on with diagnostics.
Operate the vehicle by shifting from Park to Reverse, then while in reverse, operate the vehicle with the calculated throttle position greater than 8% for 5 seconds, perform this maneuver a minimum of 3 times. If the DTC P0736 resets, go to Component Testing.

Component Testing:
Perform the line test procedure.
Inspect the check ball 5 for possible sticking or damage. If you found a concern with this check ball, repair the concern.
Inspect the shift select valve 3 for sticking or damage. If you found a concern with the shift select valve 3, repair or replace the valve or valve body.
Inspect the R-1 (Low and Reverse clutch) assembly for wear or damage. If you found a R-1 assembly concern, repair or replace the R-1 assembly as necessary.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day and Happy New Year.

Thank you for using FixYa, have a nice day.

had exactly the same problem with mine, its in my mates garage as we speak. he had to take the engine out open the gear box and check the bearings. All the bearings were worn !!!! had to buy a wole bearing kit, £170 . plus labour, lot cheaper than getting it reconditioned by specialists!!! they wanted £1000 for doing exactly what my mate has done for me. Hope this helps you!!!!!!!!!!!!!!!

my honda cbr 125cc starts up ok, when put into gear stalls, can you help me please. the year off bike is 2006.

Sixth Gear is an additional ratio. The five speed bikes have a spacer on the shaft instead of the sixth gear, so the conversion is not so difficult for someone who knows what they are doing. The shifter drum also needs to be changed. I've not done the conversion, but I have one six speed bike and one five speed bike. Sixth gear is nice for highway use. In reality it only changes RPM at 70 mph by about 500 revs. But that is enough to make cruising at higher speeds a little more relaxed. Is it necessary? Hmmm, I guess that depends on how much time you spend cruising on the Interstates. Personally I avoid Interstates most of the time, so I find it not much of a problem. Good luck with your decision, and you are right now is the time to do it if you are going to.
