I have achived top speed of 120 kmph as per speedo but its around 110kmph which was good as i was able to get the Max out of my bike. But since last 2 to 3 months i am unable to even touch 100 on the speedo i have serviced the bike regularly and there is no problem with the bike and even the engine oil has been changed accordingly. I use castrol racing 4T Synthetic engine oil.

Hence request you to please tell me whats the problem or what should i check with the mechenic?Bcoz its really fustrating to ride that slow pulsar on long trips.
Thanks & regards,
Maher

Many reasons:
1) Clogged Air filter
2) Clutch plates
3) Wrong AFR tuning
4) Wrong tappet setting
These were some major reasons. Apart from them for a 50K bike, Drive chain and sprocket change, spark plugs change, .... should be done.

try checking the carb. Sometimes clogged carb will also affect the performance

Thanks a Lot guys will do the above mentioned checks and will look at the performance of the bike..... or else will have to go for a Newer and Bigger Machine like the P220's or the RTR 220(which i hope is coming shortly)

**shishirbn** · 06-08-2010, 04:06 PM

All the best for restoring the old one to its original performance and all the best for the future bike. BUt don't forget to tell us what had happened to your current bike.

**maher_mast** · 07-07-2010, 05:50 PM

Did all the above Improvements but but the bike still not feeling that gr8 as i was used to ride before.......

I jus think its the time to go for a Bigger Engine bike for as i am toooo tired with my P150 will need to go for some new bike

Any one as any idea of any new More than 200cc bike coming to India

Sometimes it feels great when you find someone who faces same issue as you do.

I also have a Pulsar 150 which does not go beyond 90 kmph. I have changed clutch plates, pressure plates, tires, timing chain, chain set and what not. It still doesnt go any more than 90 kmph. My bike also drinks oil, although the smoke is not noticable. I generally ride at 80 kmph, which it attains quick and effortlessly. After that it kind of hits a wall and does not go beyond 90 kmph.

Now, having changed almost everything, what it seems can resolve the issue is changing the valves and cylinder-piston kit. But I am not spending any more or taking a chance with it.

Haha I can imagine the agony. Recently I was doing a long trip and a Platina (100 cc?) overtook me. I was already riding at full throttle.

I felt very sad.

**raghu13raman** · 07-08-2010, 12:12 PM

I thought i am the only person with the problem. Of late my A150 has the same problem it touches a max of 95 KMPH but struggles to go beyond

. Previously used to touch 110. now the performance has gone down.
Changed valves apart from clutch plates and sproket kit, but no use. any ideas would help.

Regards,
Ram

if you have check these things and the problem is still persisting

check...

1) if brakes are tight.
2) wheel bearings are worn out.
3) rear wheel sprocket bearing worn out.
4) chain is too tight. make it loose.

i had the same problem and also one more guy, there was a thread here which you can search for the same problem. check the above 4 things, other than these only block piston remains.

**thapasundi** · 08-09-2010, 01:36 AM

guys,
I've 2005 p150, on which I enjoy riding on high speeds, I touched 123 kmph on it many times, but in 2008 its performance was gets low, even an RX100 guy overtook me with three guys on it!!!!!
I immediatelt consult BikeZone with it, they get my engine onerhaul done, and now its almost two years, I ride my babe 110 kmph+,

I think in my openion you shuld consult with an experienced mech.

Hope u'll be able to get speed, after these works...

when the bike gets old, the engine losses increase considerably..hence the drop in performance is due to :
1)worn out valves
2)worn out timing chain
3)carbon build up on the piston(decreasing the cc and increasing compression ratio which causes vibes) as well as exhaust and intake ports(the engine can't breathe freely) and the silencer(choked exhaust presents a resistance to out-flowing gases)
4)carbon build up in the spark plug wire thereby decreasing the spark intensity..
5)worn out clutch plates
6)worn out sprockets and chain
7)loss of lube in the bearings of wheels

so if you guys want to get the same kick as from a new bike,check for all of the above..but remember restoring is a tedious process and not for the faint-hearted.

goes effortlessly till 80-90.. but not above that..
I am thinking worn out clutch plates..

let's C.

one thing here.. last time this happened around 10K KMs back.. I got spark plugs changed.. and that instantly brought back the life .. please get that changed..
80Rs. each bajaj ones.
160 rs. each NGK G-Power ones
550 rs. each ngk iridium ones..

Try replacing the air filter. Costs just about Rs. 20 and it can can improve the top speed a little. It worked for me.
