  • p180 to p200 conversion

    I am bored of the P180UG3 that I have. I wanna bore it to 200CC. So I want suggestions regarding oversized pistons.

    1.Is it recommended to over bore the current 180cc to 200cc or just get a P200 bore piston kit?
    2.Also do the exhaust and the head need to be changed? And the carb jets?
    3.What about the crank and the clutch plates?
    I have heard the clutch plates wear off soon due to the extra torque.
    4.Cost?
    strict non cosmetic mods

      What you need to do is get your hands on the parts catalogs of both the 180 and the 200s. compare the two, and see what components are different.

      As a general, it would be better to go for the 200 bore. though im not sure of the stroke specs. You would need to change the con-rod, the piston, rings, head, cams etc.

      ALso the clutch would have to be compared, and checked.

      Mate, just get a new bike.. why go for the hassle!

          A bit OT but Sorry mate your signature's just too big. For someone who's seeing it for the first time, it almost dominates your post completely. However, I do appreciate those links, but the sig needs to be cut short. Please don't treat this as an affront because it is not.

              Hey, how about selling off your P180, + add a few grands (almost the same amount that you'd spend on the mod) and then purchase a used P200 for yourself? If you too, –much like myself– believe that a P200 IS the only better option in the (used-bikes') market once you lose the P180 –of course not counting the P220DTSi, coz its in a league of its own... and you won't find a used one so easily– then this should be a good idea.

              Also, (not starting a war between the two bikes, but) IMHO each bike (the P180UG3 and the P200) has its own unique identity and plus points over the other. For instance the P200 is more of a 'thumper' (if you know what I mean) while the P180's more of a rev-machine.

              Besides there's just a 1.5Bhp difference in power between the two, so how bout a K&N+upjetting to help bridge some of that gap? You could also get a 120-70/17 rear tyre to go with that, get rid of the rear mudguard –maintain the number plate though– and you'll start loving that P180 once again. And oh yes, the split-seat mod isn't too expensive as well. You could do all this in roughly about 5K.
              You really think I wanted a P200? And I hate used vehicles. You don't how the previous owner f**ked it. And a used pulsar is a strict no no.

              Why not stick to the topic than give your valuable comments like get a new bike and all. PS my 180 is just an year old.
              @abdelazeez i didn't ask for what poser mods I can do on my bike. K&N and upjetting for 1.5BHp? please..... K&N is lame

                Woah, Your response could have been better. And no one knows if you liked used bikes or not right? It not their problem, its yours that you are bored of your 180.

                as Suggested by jd666, that could be possible soultion. Usually, improper reboring leads to many problems (this was just a fact, not a comment).

                  1)Dont overbore the current, go for a new bore piston kit.
                  2)exhaust no changes, just some desi jugad for free flow will do.
                  head - no changes,
                  carb jets - stock
                  no k&n
                  3)no problems about crank, that "extra torque" will not be that much
                  clutch plates will wear a just little fast(under normal riding).
                  cost, anywhere between 1700-2200.(mech charges extra)
                  Have fun..

                  ps.the 200 kit is direct fit, no changes. may be little tweaking to timing chain tensioner.

                    If you ask me, the mod is just not worth the effort and the money spent!

                        what exactly are bored of?? the acceleration? top speed? ???

                        and what is the performance increase that you're expecting once you've done this mod?

                        i have a 3 year old 180UGIII... considered doing this.

                        didn't do it because i rode a bike that had the mods that i was intending to have done...
                        about 8 months after the mods were done...
                        hardly made any difference when compared to my "stock" properly maintained 180UGIII.

                        you'd prolly get what i mean once you've ridden a P180UGIII with these mods... it's disappointing!!!

                        not worth the effort.

                        tho... sprocketing is an option... and it falls under the non-poser category of mods.

                          WTF? just 2200? Man thats good news. I don't even have to save up.hehe
                          hey u sure no mods to the inlet and exhaust port size are needed for a 200? and the jet size?

                              kit is direct fit, use two base gaskets instead of one(to reduce engine pressure).
                              inlet, exhaust can be modified later(if you wish to).
                              stock jet. i tried karizma's 125 main jet(again direct fit) but bike was hesitating at 8k rpm,
                              buying parts is easy, modding is not. make sure that your mech is good enough.
                              and i m sure about pricing, 1700 was what i paid.local agency was adding +12% vat.
                              got it from a spare part dealer.
