Confused what to do with my Honda 70

[Automotorsport_Lover]

today got time and went to mechanic as bike had also started a little bit of white smoke so he opened the engine starting form head we found that valves had been worn out and engine had alot of work apart from head the things needed to change were

1. valve =Rs 450
2. valve seal =RS 180
3. timing chain sprockets =Rs 180
4. timing chain =Rs 220
5. oil pump sprocket =Rs 250
6. piston ring (Atlas Honda)=Rs 400
7. kick lever=Rs 150
8. oil seals=Rs 200
9. gas kits=Rs 150
10. Timing Chain spring=Rs 50
total= Rs 2230
+ did tuning oil change and kairad work on head with labor and every thing it costed 3300
will get the bike tomorrow as it was too late to assemble it so the mechanic said that will continue tomorrow will update the result of spending 3300

So as told, it was problem with ur valves..
Its normal, when head is opned these things are to be changed.

Oil pump, valve seals, gas kits etc are understood and piston rings is due deligence... ur mechanic did the right thing!
now as the rings are new drive softly for some while... do runing for 200-300Kms.. let the stuff adjust properly.

Now you need to complete the break in period cautiously..No hard accelerations and speed above 35km/he atleast for some 700 Kms

Yep! usually when the engine is dismantled you end up changing/repairing anything with little sign of wear and tear and thats Due diligence. The replacement of timing chain and timing sprocket indicates your engine was runing rough matlab engine timing wasnt right and that must have caused the Black smoke rather than white.

got timing chain replace around 10k km ago never adjusted the timing again had replaced it from some other mechanic but now when my mechanic open it he said it needs replacing waiting for it to be back on road

[makniazi]

@aximaxim yes i think engine was running rough because bike had a lot of vibration hope it will be fine now

Head is in very bad shape.. a lot of carbon deposit in it... the head is totally black! valves are bad too....
After cleaning the head and fitting new valves.. u will see a shiney clean engine!

Bike is running fine now and is back on road this is how it looks now

cmon man 35kmph ? seriously

[devilskreed]

cmon man 35kmph ? seriously

Sir gee all for the sake of better sealing of pistons in the combustion chamber..When they have sealed in then he cna do whatever he like

he can strech it upto 45 plus kmph if he give rest it after intervals on 10 to 15kmph . chaskay laga laga k running kre agar

[talhabinomar]

In the running process the speed can be reach till 50 km/h but you have to use all four gears

[makniazi]

rest after 10-15 km hmm that's nice cuz its almost 14 km to uni from home means 14 in the morning and then 3-7hrs rest and again 14 km back home matlab i can go upto 45-50

[talhabinomar]

yes but you have to use all four gears.

[user-xxx]

plz keep thiking , do google n utube , wait for an appropriate derision to come in ur mind make a budget. engrave ur statistics . than perhaps wait at least a year . then do what u want to do with ur honda 70cc uncle.

AOA all posting here after completing the running period and bike is running fine actually more than 1000 km done i guess around 2k bike is running awesome pick and power is good touches 100 gps speed not the speed on meter tuning done recently now the problem is that when the bike's engine is hot bike does not idle yesterday i opened the plug to check if its rich or lean but the plug was brown means it is running fine giving and average of 45 km/lt at an average speed of 75 to 80 i was thinking that is there something wrong with the carb ? if yes should i go for a new one or get it repaired

I guessing while you were breaking-in your newly built engine, the metal shavings from the engine could have clogged up the idle jet in your carb. I think a blast of compressed air will suffice. No need to change the carb.

aximaxim cleaned the jets yesterday one thing i forgot to mention is that crab needle was no straight the guy did some hammering to straighten it and then smoothed it with sandpaper could it be the problem or electrical problem ?
