Approved and merged!

None of the things that happened to you happen out of the blue. They start leaving tell tale signs earlier. Maybe you never could notice.

Re: Bajaj Pulsar 150-UG4 over heating and changed of bike engine sound


Better you directly go for a fresh bore piston kit instead of a re-bore. The spares are very cheap and it is much more reliable too.

Re: Bajaj Pulsar 150-UG4 over heating and changed of bike engine sound

Hi Krishna,

Thanks you so much for your advice.

Could you please let me know apparox how much cost is required for fresh bore. and let me know if you are aware any thrusted mechanices in bangalore.


Thanks,
Devakar

Re: Bajaj Pulsar 150-UG4 over heating and changed of bike engine sound

Oops. I am not aware of the 150cc bore price, for the 220 it was less than 2.5k about a year back and still is somewhere between that range.

So for the 150, it should be only cheaper.

And about mechanic i think i can suggest Khivraj bajaj as i have heard they are best here. As I am not a native Bangalore-ian, I am not aware of local shops. I'm sure other Bangalore members can help you out on that.

Cheers

Re: Bajaj Pulsar 150-UG4 over heating and changed of bike engine sound


Hi Devakar,

I have recently gone for Bore piston replacement for my bike. P150 2005 Model Alloy wheels. Go through Pages 152-154 for the process and spare parts prices. Exact prices were in page 153. The prices were after discount. The prices for your model are more or less the same.

so try to buy in Big genuine authorised Bajaj spares shops which offer discount. AVOID BAJAJ SPARES attached with showrooms. They simply add VAT and other taxes.

Run-in process, oil changes and oil filter cleaning were discussed thoroughly in the above mentioned pages. Go through them and try to follow for best results.

Re: Bajaj Pulsar 150-UG4 over heating and changed of bike engine sound

Hello Guys,

I am planning to change my bikes UG2 handle bar for a relaxed position. I have read in "Unicorn Dazzler" thread that Discover handle bar will be suited for pulsar upto UG3.

Any specific model Discover Handle(with end weights) should i have ask at spares shop..?? Any idea guys..?? i.e; Discover 125 1st model..?? D135..?? or any other..??

I want to know that, will the length of disc brake fluid pipe is ok or will fall short because of big handle height..??

I am asking about this. What will be the price of it..??




Also i want to change the handle bar grips to smoother ones. I liked the P200NS grips. Has anyone tried them.?? Do they exactly fit for the Discover handle..???
AFAIK the diameter of handle bar hole for Discover Pulsar 150-220 and 200NS will be same..
Are the spares (especially smaller spares like grips) of P200NS easily available..??



The accelerator cable and clutch cable lengths will be ok i think so. I will make grooves/holes to handle bar for switch sets at lathe, as i did earlier for fitting P135 switch sets for my bike..

As far as P150 handle bar position is not bad but somewhat relaxed position is better. As i am residing in a city, it is getting somewhat stressful to ride in traffic in sporty stance for LONG hours and that too frequently. so i decided for this mod.
God knows how the guys on an Apache are managing.

As i am thinking to go for that handle this week, guys Please answer my queries. Thanks in advance...

Pulser 150 ug3 headlight not turning off,cant selfstart,and idling issues

Friends,
Recently i purchased a pulser150 ug3 2007 model bike,bike was in pathetic condition from engine to body major works done
.piston cylinder kit change
.crank bearing change
.new valves seals,camshaft,cam sprocket timing chain
.new clutch plates
.new seals and packing
.wheel bearings sprocket bearings changed
.new chain sprocket
.new uno minda wiring kit
.second hand BCU
.All nuts bolts sinked
.fairings also changed
friends engine is working fine,no pick up issues no starting problems in kick start,but the problem is that headlight is always on i cleaned the rhs switch then too no change,headligt and pilot light just doesnt go off,also light intensity is also very low,another issue is regarding selfstart starter motor is turning the engine but there is no spark at plugs,but in kick start there is no issues,also engine is not idling im not able to tune the carburettor,idling rises at a point of time and comes down at regular intervals,afr screw turning is not making any change,friends i dont understand what is the problem,when enquired with bajaj they are directly telling to change everything from BCU coils switches which i cannot afford now,please give me your valuable suggestions friends

Re: Pulser 150 ug3 headlight not turning off,cant selfstart,and idling issues

Hi bro,

i will give you an advice, if you wish to keep the bike for more than two years.

take the bike to a good(best) bike electrician. Inquire in your city thoroughly.

Now buy Pulsar 135 /Latest Pulsar 150/180 switch sets (both are same, even same for Duke), cost around 1000 Rs. Thats it...!!!!

Take your bike to electrician. Ask him to remove BCU and present non contact switch sets.

Ask him to make mod for connectors to hold or for connecting P135 switch sets. IT CAN BE DONE.

First do this thing.

Now all complete electricals issues including starter, headlight, indicator, and whatever you say will be rectified.

Even if the self start problem persists, ask the electrician to test your bike with a CDI he is having. The electricians will have a spare for testing. If he is not having, take it to Bajaj ASS and ask to test CDI. They will definitely have it.!!!!!! I think for your model it is DH 11 1061 (I think)

why i have said to check for CDI is... if CDI is gone.. it will create idling problems, starting problems. Raising of RPM and coming down at regular intervals is a problem of CDI. I have faced it once. Its problem of CDI.

If its not CDI then its carburettor, but you have said that engine is working fine without pickup problems. If carb is also ok then it is valves problem. but as your bike engine is new. it will not be an issue i think.

If all are ok then its nothing but stator or high tension coils. But these will not be problem mostly.

Hope my points will help

Srinivas

Re: Pulser 150 ug3 headlight not turning off,cant selfstart,and idling issues

dear brother sreenivas,i have a doubt if rhs switch is complaint does headlight always go on,i mean is headlight a through connection and the switch is used just to short it and turn it off,and again rhs headlight switch is a non contact one and it is conected to bcu,so is there any possibility for bcu being the culprit,as u said im definetly going to change the stator coil because headlight intensity is also low.
brother secondly as i told in kick start just with one start engine is coming to life but when applying self there is crank rotation but no spark in spark plug,so is it because stator coil is weak it cant produce spark in self start rpm??anyways brother as you said as the earliest will change the switches,coil and see any change,bro one more doubt if cdi is fault there will be no spark at all right?

Re: Pulser 150 ug3 headlight not turning off,cant selfstart,and idling issues


Bro.. As you said that you have gone for a second hand BCU and as the Bajaj ASS is asking to change all BCU, Switches and other stuff, i ahve given the advice to go for P135 switches. Let me explain this...

BCU... around 1100RS+... will your problem go away...???? Ans: Maybe
Will they be permanent without any problem in future..?? Ans: Maybe

Non contact switches.. around 1000rs+ for both.. will your problem go away...???? Ans: Maybe
Will they be permanent without any problem in future..?? Ans: Maybe

The cost here itself crosses 2500Rs+..

I am asking you to go for P135 switches.. Cost 1000RS+.. will your problem go away...???? Ans: Definitely. the connections problems will go away.
Will they be permanent without any problem in future..?? Ans: YES.. i am using them...!!!!

I will explain you about the electricals of Pulsar UG3.

BCU is a relay type thing that gathers the signals from non contact type switches and other sensors then processes them and delivers the output. Water and other harsh environment may spoil it..!!! Also troubleshooting is much difficult. this is the reason why Bajaj has removed BCU in 2014 UG5 models of Pulsar150 and 180 and also P135, P200NS have regular contact type ones...!!!

In your headlight case may be RHS or BCU are culprits. One thing bro it is 2007 model bike and the parts are aged. why to take risk in replacing one or other of those parts..?? Just throw them off...!!!

Please dont change the STATOR COIL first..!! It cost around 500RS+ Check condition of headlight bulb after rectifying above problem.

Now check REGULATOR. (The below process is after changing switches/rectifying switches .The headlight is in off position normally but when it is on the glow is dim.)

I will give you process for checking regulator (for lighting) if you have a good spare bulb with you. Take 2 wires a metre length each. Dont remove the regulator from its socket.

Identify the YELLOW wire (not yellow red) of regulator, try to connect a wire(1st wire) to it or touch at that yellow wire connection and connect the end of wire to a pole of bulb.
Connect another wire(2nd wire) to chasis or body of bike and connect the end of this wire to another pole of bulb.

Start the bike and let it idle. dont switch on any switches. Now you see the bulb is glowing is it ok..?? Just twist the throttle... Getting good/Full intensity...??? then your Regulator is Good...!!

If the intenstity is not good then REGULATOR is culprit. If it is problem. Please DONOT CHANGE regulator immediately. Reply me...!! I will tell what to do..!!! (AVY stator+AVY RR swap+ one special mod done by me. I will tell you)

Now i will explain how the engine ignites upto UG3 model..

You ahve kicked the kicker. Magent (you can see it in glass of stator cover) rotates on dedicated pole (yellow covered) of stator, then current generated comes to CDI and then from CDI the volatge is increased and CDI sends it to spark plug.
In your case kick starts the bike.If at all stator is weak, whatever you do your bike will not start.
In selfstart case.. it does the same thing the self starter motor rotates crank there by rotates magnet then above process... (Check how magnet is rotating through glass.. is it roatating very slowly..??) That why it takes long time for selfstart tan compared to UG4 models.
(In UG4 etc models. Press selfswitch, current goes from battery to CDI,.. bang... immediate start in fraction of second.)

Coming to CDI..
Problems related to CDI.
1.Misfiring-- Giving jerks... Same problem can be related to Carburettor (Diaphragm problem/slide problem)
2.Sudden Stop/Complete ceasing of bike. Whatever you do Bike will not start
3.Bikes RPM slowly raises from a RPM and stucks at a RPM and may not come to idle (1*1000RPM) even if throttle is released. (In my case the rpm raised slowly from 1 to 2 and from 2 gave a sudden jerk and it remains there after riding for some distance.) Same problem can be related to Carburettor (Diaphragm problem/slide problem) and also Valves

As you said that "idling rises at a point of time and comes down at regular intervals" i asked you to check CDI (But not to buy it)

So after changing (if you wish) switches Go for checking CDI. Dont buy it. Ask them to check with a spare.

Bro.. Please check whether the REED switch (Black switch) is present on carburettor. (You will see a small black magnet type thing which moves up and down on throtlling.) It controls the RPM by sending signals to CDI. I think its called Throttle positioning sensor. Google it you are unable to understand what iam saying. It costs very less, may be less than 10Rs i think.

I am assuming that your spark plugs are new.

2 and 3 Problems of CDI happened for me.

IMPORTANT NOTE: if you are going for P135 switches, you stand while he is doing the work. Ask him to modify the connectors by removing them carefully but dont allow him to slice any wire. Ask him to use from his old wiring(gone) sockets if needed. Be strict to him. Tell him that i will pay you good if he does good work. Demand him to not to cut any wire.!!

I am here to help you out max.. Reply me if any help needed.

I feel very bad about UG3 to UG4.5. Suckers loot a lot from the sufferers beacuse of their lack of knowledge on these electricals. If there is a problem Just they will say to change BCU and switches. oohhhh Mannn... serious...???? Is it a Joke...?? 2500RS simply like that..??? Even the borepiston and clutch plates wont cost that much....

I am also a victim. So i want to help a lot. whenever possible.!! So bro already you have spent a lot. Even before buying any thing reply me. i will advice you the best.

Srinivas

Re: Bajaj Pulsar 150 All Versions

What can i do ..now i am only top it up and using it.....if i go for a engine overhaul.is it good or how many km can it cover after engine work and what parts are required to change.thanks...
