I always loved my Pulsar 180 UG3. Right from the first day (April 3, 2007) to the present. I roamed around, saw places, did stunts, did 570 kms/day long tours, did commutes, everything on this one bike.
While I did get bored with the 16.7 PS max power soon enough, I really didn't want to change her with something. As Noor bro says, how loyal are you towards your bike?
I did think about it when Joel told me that Karizma, P220, R15/ FZ, RTR, etc have better engines overall for modification. But I decided against it finally. This was a year or two back, but Joel finally got a kit for P150/180 ready too.
So? Finally, my Pulsar 180 UG3 gets tuned for more power. And I'm sharing my experience here as it happened:
I received the Big bore and Exhaust Kit from Joel Joseph on 13 June, 2012. That was a full 13 days after I joined my first job as a lecturer in a college I once studied in. So, I wasn't too free to get the modification work done.
And I started collecting other things to fit in, so that the exhaust can be installed too:


The piston below:

That would make it 208cc? Yeah...
I removed the tapes only to find out that the paint is easily removed due to it. I was in no mood to get it repainted anyways:

I took my bike to the service centre to have a talk with the Bajaj Mechanic so that we can find an outside location to do the work.
The modifications were not allowed in Bajaj SVC...
Finally, the big bore work was started on 13th July, 2012.
1. A jet of Size 118 from Achiever was fit into my bike.
2. Next, we tried to fit the bore and that's where problems started showing up...

The head was removed one by one:

Older 180cc block was removed:


Now, a big problem came by.
The crankcases of left and right side were a mismatch from Bajaj company itself. Due to this, the new block couldn't be fitted into it... I was dead scared.

I called up Joel, informed him, and he was sure the block should fit. Then I requested the mechanic to find a solution.
He proposed that he will scrape the smaller right crankcase opening so that the new block fits in. This took one full day but I wanted it to be done somehow, because I took a half day for it... The mechanic thought otherwise and he said it would take one more day. Damn! And the bike was to be left there only...
Plus, the mechanic was saying that this block has "JC" written on it, which means its a P200 block which is rebored. I was like, what??

And he also said the exhaust is nothing but a chamber in a hollow pipe.
I tried explaining that Joel does his research and that does take up money and time. And that even I know that manufacturing wise, its not that costly, but its the R&D that takes the price up. He didn't seem convinced. I was in no mood to explain it either due to the physical and mental fatigue.
I was so depressed that day. Well, I won't forget this "Friday the 13th" for quite a time. Anyways,
14 July: A new day has come. The crankcase was scraped and it was fitting in the new block now, without much force.
But now a new problem came up: Joel did not supply a Chain tensioner for the block, and the old one was not fitting into it. I had to search the city's lengths and breadths to get it.
Went to the main city place 2 times just to get it the right size. And people were giving me local products too.

Was so fed up, that I fought with a close friend of mine who came by. He was having fun, saying rubbish like: oh the exhaust has a dent see... hahaha, you could have got a new bike instead of spending... haha, the strange footpegs, one front other back...


And somehow the work was completed on 14th.


The above stock head was decarbonised and re-installed.

The rear set footpegs and the exhaust were installed without much trouble, but something funny happened. Not funny for me though.

The left side's footrest holder and gear lever were there but apparently some bolt was missing, the one which connects the gear lever to the footrest holder.
This meant that my right footrest holder was REARSET, and left was the same old FRONTSET. So, I ride the bike as if riding a cycle, with foot on differently placed pedals.

Here are some other pics and the summary of the results:



^^ Track use only? I have no idea what sense it makes in my situation, where I'll probably never take this bike to racetrack ever... Maybe that's Joel's sense of humor and I like it!








Its right now in running in process so I didn't cross 50 kmph or load it with a pillion.
I have fit in a 118 size instead of 117.5 from the Pulsar. Just 0.5 more? Yes, due to lack of choices.
Currently, the bike is heating a lot, even with 5 turns of the carb screw. I'm afraid more turns will just screw it loose. Will get a 125 sized jet or something soon...
Plus:
+ Performance seems to be distinctly better,
+ Sound note is attention grabbing, and I love it,
+ I expect mileage to be better than before,
+ At low revs like 2000 or so, it sounds quite close to stock, so usable for the street,
Minus:
- Packaging is very wrongly done. The tape consumed the paint color of the big bore block. The exhaust has a dent on it, don't know if it affects performance or not, will replace if Joel says so.
- Inadequate package. I had to get a lot of parts many times from the market. With due respect, this can't be called Plug and Play. Its more like arrange and assemble...
- Low rev response is so-so, have to twist the throttle to get the performance at low revs,
- Dogs are very unforgiving to the exhaust note, they should take peace lessons.
- The footpeg disorientation sometimes makes people laugh, specially when they see me from the front.
Summary: Modifications/ Tuning, is not for the fainthearted, easily depressed or the common posers. Its for real guys who can take the pain and tension. And it will always be so, until complete kits are supplied.
My message to Joel is: Thanks bro. The bike is really good now, but the 2 day headache was too much for me.
Please take the feedback from this article and try improving upon the services, packaging and kit level.Do supply a chain tensioner, gear lever bolt setup and brake lever bolt setup, etc. to anyone who buys it for P150/ 180.
These parts may not cost more than Rs. 200, but they're so rare that I couldn't get them anywhere, at Bajaj, outside Bajaj, anywhere. Thank you so much again bro...

Will I recommend it?
Yes, if you can pay the price and handle the headache involved... But you can handle anything, right? You're a biker, isn't it?
The guys who'll put this in 150cc Pulsar should get a huge performance gain.My setup is good, upto 4000 rpm its clearly more punchy than P220, but not the Karizma though. And the low weight helps a bit. So, I'm happy. Let's hope nothing goes wrong...
