    P80X Cylinders

    Post by 2ToneJake on Tue Sep 11, 2012 11:19 am

    i've just been looking in the sip catalogue at different cylinders for the P80X, but i've found out that the opening is slightly smaller than on the 125 casings

    they do sell certain kits for the P80X that are for the 125/150 but they have altered the bit of the cylinder that goes into the casings so its narrower, but i dunno if it'll be any good - does anyone have any experience using one of these altered kits???

    they do sell 135's for the P80X but i dunno if it'll be any good, i was wanting this scoot to be a bit quicker than my current one

    how about measuring the case spigot diameter on the 80 case and comparing with a 125 case to see if its the same.

    If it is smaller you could probs get it machined out

    i dont know exactly how much smaller it is but i've just tried a 125 standard cylinder and it wouldnt fit

    do you think the altered kits they sell will be no good then? in the catalogue its like an extra 30 euros which isnt too bad tbh, just didnt know if they were any good

    no im not saying that pal. The spigots being machined down on the barrels wont make a difference to performance.
    If you get the casing machined out it will be like any other 125 casing then

    If you dont your purely restricted to the 135 kits or whatever else there is

    A lad I met the other week has got a p80x import with a malossi 135, he says its good for 60 cruising which aint to bad

    60 cruising off a 135?

    thats pretty descent, my 166 only cruises 55 - 60, did he have all the trimings done aswell though? crank, gears, flywheel etc

    how does the DR compare to the malossi?

    would i not be better off just getting one of the adapted larger kits and just installing the longer crank?

    Might aswell just get it machined, for the cost it will open up a lot more doors for you in the long run.

    Plus you could probs buy the same kit as what you have now on the px then with a bit of work you could easily get more out of it.

    i can get the 166 on it, sip just machine it down abit for the p80x - i can get polini 177, malossi 166, DR 180 and one of the quatrini kits

    theres plenty of choice there, just need to choose the kit that's best for touring seeing as i cant get the pinasco

    Aye, I guess it does all depend. I sure using the polini 177 would be fairly alright for a touring setup. But then again, if you speak to Ian he can probs help you out with port timings etc to get the best of what you need.

    aye, i dunno where to start tbh - it needs a longer crank for the kit cos its different length on the 125's, so i have to decide what type of crank n all that shite so it goes well with the kit

    think it'll get the uprated primaries too and just stick to the 24 dellorto si to keep it simple

    It's not to hard to make a half decent quality motor. Try not to think too much into it, I personally think theres too man options nowadays.

    Tbf there's only 2 things people want. Either a low revs tourer or a fast as fuck rev monster. It's budget and knowledge that is the biggest comprise.

    My personal thoughts would be to leave the 80 engine as standard and either bang a std p2 in or have a play about with a 177 polini barrel on a 125 casing. If you spend some time with the porting and get the cases matched then it should do do well.

    Polini's aren't bad IMO.
    Malossi's tend to rev higher (in the smallie world they do anyway)
    I know a fella with a t5 with a polini 152 but it's had a few rebores so obvs aint a 152 anymore.
    That goes pretty well, but has nipped the odd time.(which the 152 are prone to seizing)

    i've only seized the malossi once, but that was my fault for getting me oils mixed up
    is the 177 as prone to seizing as the 152 is on the t5's?
    i do like the sounds of a torquier scooter more suited to touring

    The biggest problem on the polinis is the casting are shite. Piston clearance from standard is too tight (needs to be 4-5 thou) and the port edges are rough as a badgers arse. But this is easy to rectify with a hone and tidy up. Likewise a bit of work to increase the exhaust port will add a bit more low down power for not a lot of ££. With it being a low revving kit there shouldn't be an issue with overheating from it being iron like there is on the T5 (it seems illogical to replace a standard ally top end for an iron one), though that said I know plenty of lads running 152s for miles with no issues, but this is largely down to them putting a bit of work in before they fitted the kits.

    And you should be checking things like piston bore clearance before changing either barrel or piston or both, so this isnt extra work. If you dont, you run the risk of either piston slap or nipping up.

    I dont see why..so far the idea of machining the case spigot out is out the window. It will just be like any 125 case then. No fucking about with sourcing machined barrels then.

    Or is it the fact you cba to take it to a competent machinist ?
