there is a question guys,
my bikes idle rpms were 1300 from starting. I have observed that from some 1000 km or so, when i ride lets say 20 kms, the idle rpm is 1800.
Is this normal or i should get it retuned? Why would that happen?

It is normal bro. The idling is going higher because your engine has reached the optimum working temperature.


Cheers,

Hi guys,
I installed a 180cc big bore kit from Joel.
Had it installed at the Yamaha svc in TVM. It took them 5 days to install. Had to switch to 115 main jet to fuel the larger cc engine. I did not push them because I wanted the job to be done with special attention.
The engine is still within the 2K run in and I am keeping the rpm below 4.5K.
There is a knocking upon accelerating from a stand still or when going up a slope. However, now 300+ kms with the kit, the knocking has come down.
There is a noticeable increase in torque and pick up. I have not yet tested the top end speed because of the run in period. I am unsure of the mileage at this point. But I have observed that it drinks a lot of fuel during the city runs. Mileage is not a major issue for me as I usually use the bike for my weekend trips only. Hope all will fall into place upon completing the run in.
My next step is to fix the Cosworth air induction kit I had bought some time back. But this needs a bigger carb. The stock carb will not suffice.
I am now in search of a P180 29mm carb. And the search is not successful.
I have asked Joel to source a bigger carb. Awaiting his response.

Hope to get response from everyone and especially from guys who have installed 180cc kits.

Guys I serviced my bike on 15th march when I saw that the battery in my bike is of AMCO company. I had always heard that the stock battery is of MINDA. I service my bike at YFS Kestopur, Baguiati in Kolkata.
Also I want to know how the adjustment of the drive chain should be, I mean that should it be too tight without any slackness as done by the SC or should it be a little loose to make it move somewhat freely.

please reply guys

whenever I try to upshift before 4.5K rpm i find it to be very rough .. however things get smooth at 5K and above. Its been only 1K kms since my last oil change with a total running in 17K kms. I'm on SS. Is this normal or an issue with my clutch plate/setting?

i would highly recommend please get the mods done only from Joel. He is the best person to suggest you to take the necessary steps for the same. Please don't experiment with getting parts from somewhere else. Not because of the fact that he will make more money out of you but because he doesnot guarantee that his kits will work efficiently with other performance kits from other suppliers. You will most likely need 33/34mm CV carb Mikuni to get better response.

I remember speaking to RanjithMN on his experience, post headwork on his bike.. the mileage is not going below the range of 43-47kmpl on his souped up ride.

The knocking issue is most likely because of inefficient fuel supply to the chamber. I guess Abhimanyu31 is the best person to give us gyan of the century on this one

Cheers,

shell ax7 is my favorite in ss.. Though motul ss is superior

The P180 29mm carb was recommended by Joel.
I had bought the Cosworth induction kit long before I even thought of installing a BB kit.
Yes, the knocking is mostly because of the insufficient/inefficient fuel supply. And I stopped searching for a bigger carb locally; contacted Joel for the same. I am yet to receive a response from him.

Thanks Shv,
Idle rpms should be set at hot engine. Will it cost me some smoothness in cold engine if I reset it when its hot, back to 1300. Will cold engine rpm get low to 1000 or so then?

.... You will most likely need 33/34mm CV carb Mikuni to get better response....

I am sorry, shv18, but 33/34 mm. carbs. would be FAR too big for a 180cc. Even for my 200cc. (FZ 20!), a 29 CV Mikuni, or 28mm. "flat slide" are the correct dimensions, as also confirmed by other posters here-above.

About having parts and works done by Joel Joseph and none else unless you find a real equivalent: I must say that this is a wise advice! An other forumnite fo bxhp, from Vietnam like me, has also bought parts form Indonesia: not only did we wait three months (YES: three months!!!....when I think I was complaining about Joel's slowliness....) to finally have (most of: not all) our parts delivered (damaged!), but they were far from the "plug-and-play" this reseller advertises. So the advice is: go to a professional, proven, experimented engineer and bike tuner, and forget about those "glorified mechanics (Joel's words!) who just sell you parts of various origins, not tested, nor properly engineered, and who does not do the installation either.

Anyone?

What is the exact oil name? I mean, like 20w50 oil, what is the grade of it? Where would I get it in Kolkata? Any good SS in Castrol range? And price of Shell ax7 and others plz.
