    Oil

    Arnandal shell helix is a very good oil and what you had chosen is meant for the cars. The difference between car and bike oils is as follows.:
    1. The heat range....most cars have radiators and liquid cooling to maintain engine temperature within safe 80 to 90 C. Hence the oils used will not experience heat shear..Most of the Bikes are Air cooled, and hence while accelerating the engine oil will undergo severe heat stress.
    2. Car oils have Friction Modifiers to make the engine run smoother.In cars clutch is invariably dry and engine sump is wet,and they are Physically separate.In a bike the clutch sits inside the engine and is WET. So the oil SHOULD NOT HAVE FRICTION MODIFIERS.So if you use car's oil in bikes Clutch Slip will occur.

    Just didn't match the size of the head.

    >can the p220's clutch assembly be accomodated in mine. am looking for upgrading it.

    when i had a chat with the service advisor of bajaj i remember him saying that clutch can handle these loads when i was mentioning him about the way i ride. And he took it to be a normal ride, and this was supported by another friend of mine.
    and the SA also mentioned that longer high speed drives can burn the clutch easily.. even if the clutch ic untouched.... is this right?

    Am facing this clutch issue from 600km on the odo... can it be like some idiot might have installed 150's clutch assy in mine (as i have read in some post here, of this issue)

    [p180ug3] i was getting 59kmph at 5000 rpm without k&N and 68kmph with it, and 100 near 8000rpm (with and without k&N)
    afaik shell helix hx3 is designed to be used in cars if you use it in your bike it will lead to clutch slippage switch to castrol active extra 20w50 or valvoline 4t premium 20w50 or at least yamalube of the same specification

    Your service advisor is wrong long high speed drives WILL NOT harm the clutch as you dont use clutch during these drives ,you will burn clutches if you are in the habit of riding the clutch or riding for long at half clutch

    Very true indeed.
    No one owes to psr more than me, he was the only help i had at that time.

    i had used oodles 3 bond to make the 2 gaskets into 1.
    But still i had to face oil leak issues.

    I've machined off 0.5mm from the head.
    Couldn't go deeper as the valve seat was near.

    But I've got the sides grinded too (the one's where the valve seat area is absent), its nice and smooth slope all the way matching to the combustion chamber.
    Hence the overall decrease in the chamber is more than just 0.5mm dip.

    I've been running the stock head and 2 gaskets under the bore previously (with a 5.5mm increase in bore), there was an engine knocking issue which i had even after that, hence recently i got my head enlarged and also got valve seat grinned.

    The reason why i gave up the 2 gasket plan (which did settle me down with my engine stalling problem) was because i was not only having knocking issue, but these 2 gaskets were leaking oil from below the block.

    all thanks to psr to guide me into the 2 gasket funda.
    It helped me bring the bike back to life.

    psr... kb100...
    thanks a lot guys, once more....
    will update you with the mods...
    my first step would be changing the camshaft...
    so would know how much each one can have the effect.
    Take care
    (You both have a pm)

    If you are using local mechs then try and get it done within a day DO NOT let them delay it as it is one of the common tricks employed by the mechs to fleece you ,first get all the necessary parts like the bore kit, the packing kit ,new spark plugs (ngk cr9e) etc if you are adding an extra base gasket then a-pply a thin layer of anabond/ threebond paste b/w the gaskets . stay with the mech during the whole process ,if you need it done to any standards ,....
    and all the best for the mod

    really informative...

    u guys were very very much helpful... n psr's image.....

    thanks a lot...... a lot..
    Arnie if you have good knowledge of the basics ,anything is easy..it only needs an effort....so the bottom line is Go for the mods..ONLY if you had understood the basics...It is easy to tell you to do things..but ultimately,remember it is you who is going to make it happen.
    Best of LUCK..
