Hi Im wanting to up power my electric start, disc, PX 200e for "touring" purposes. Thinking Malossi 210 (or bigger), Malossi pipe, and "Malossi" 30mm carb. Will this increase the power "much"? Thanx  |

Just for "touring" eh? Depending on your ability with the spanners you may have a lot of options. A Malossi 210 is not the best choice for touring, as they can do it but are more suited to higher rpm. A Polini 208 or 221 (even better) gets my vote. Exhaust SIP road 2.0 Whatever you decide you won't need a 30mm carb for touring, the 24/24 and autolube will be fine for that  |

For touring, i dont think the new polini 221 for 60mm long stroke crank + bgm bigbox can be beaten for low rev torque (and goid cruising speed! and power! and ease of fitting)!! at not so high revs as the Malossi too. (It doesnt look so bad as a street racer either)!!!!
You dont necessarily need a massive carb or expansion pipe either. You can keep it looking pretty stock too.
If i had the $$$ that would be my next choice without a doubt.
Id certainly think long stroke for touring anyway.
Pinasco also works well for touring (long stroke only) but will require a little more tweaking.
The Malossi sport still seems a bit rev hungry.

You'll not get places any faster with a kit. The standard bike will pass you as you fill up more regularly - A mate with a 207 and I put this to the test about 15 years back - Lancashire to Great Yarmouth, my P2 v his Polini 207.
We both thrashed the arse off them, he had a good 10 mph more than me, and I passed him about every third petrol stop. We got into Yarmouth within five minutes of each other. Fuel cans were carried too, and used.
Unless you fit a bike tank of course....

I'm satisfied as I have Sip Road 2.0 exhaust pipe. That's good enough and I'm not about to purchase any tuning cylinder at the moment. I could afford propably, but stock cylinder's low end torque is what I like the most. And the reliability. I quess it works forever.

with the stock cylinder an sip road2 youve got 1 of the better set-ups for mile-munching , an not having the shortened service/repair intervals of a kitted cylinder ,for a tourer scoot the 6000mile ring changes on some kits will mean every year or 2 , instead of every 5-6 on stock. have you considered sticking with your set up but experimenting with gearing ,primary/clutch or just 4th, getting a scoot that will still cruise at a respectable speed but at less revs=less stress on engine an more mpg,but probably a drop in acceleration ,swings n roundabouts , h

Every five or six years?
Really?

Hi all Thanx for the info. Might try the SIP road pipe as a start. Will rebuild the engine over winter. Replacing bearings, seal etc. So will have a think about kits for a while. Thinking a "bigger" 4th gear is a good idea. Any ideas on a good size? Moi Partanen. Missä sä olet suomessa? Mä asun espoossa. |

yes nik .5-6 years is the max tho,were not all "rally hounds" like you, for some,me included, a touring set-up is for daily/weekend use with occasional longer journeys/holidays ,in my case all on a roads ,not as i suspect you put "1 careful? owner" to, a daily hack that then gets pushed along motorways after work on a friday evening to get to the party/rally as soon as possible.i'm too old n cautious an achy to do that sort of miles on a scoot.an will confess that as soon as the journeys over 15-20 miles or includes motorways i reach for my bike keys by instinct.there's something to be said for a vehicle that will hold 80mph for 160-170 mile stretches between fuel/fag stops (not at same time,thats frowned upon)without a numb bum or aching back .an will do it all back again the next day without worrys about breakdowns.an the harder servicing is set off against longer intervals.anyway i'll stop talking "heresy" before the "villagers" gather with pitchforks an burning torches.
hangarb, a "bigger" 4th ,i guess ya mean a "longer" ratio to up ya cruising speed ,this will give ya scoot "longer" legs but at expense of acceleration an "holding" on inclines.on a stock motor they can struggle to hold enuff speed/revs at the change from 3rd to 4th, to pull cleanly going up,especially on say a motorway incline .the engine needs a kit with loads of low down torque to not bog down below the power band .on the "vespa smallframe forum" in there stickys they have a gear/ratio tables/calculater, its set up with smallies in mind but am guessing the maths should still work on large frame ratios .hours of fun researching your optimum 4th gear,but large frames are less well catered for in gear changes an your choices are limited ,unless ya a lottery winner an can have gears made to spec.
most stick with the t5 4th gear ,but ive been thinking of a cosa box recently ,having heard that even people who slag all other aspects of this model (mostly without riding 1) will grudgingly say its the best "geared/ratioed" vespa piaggio came out with .the problem is finding a gear set without having to buy a whole scoot an breaking it .dont forget though by changing your clutch/primary you change the ratios on all gears an might be able to find a sweetspot for the kit you plan,an its easyer done than gear changes.

IIRC the gears in a Cosa are the same as a P2, it's the clutch that's one tooth smaller. I'm running one out of mine in the P2 at the moment, and TBH it's great at holding speed etc, but it revs too high for me.
I was just thinking of the actual length of time in the piston, I'd be concerned about the rings building up with gum due to not getting hammered very often.. Obviously not!

yes ,you might have to pull the barrel an de-gum an check the gap ,but you'd only notice the drop-off in performance when touring not in daily use really .an i'd of done that as normal check/prep for a longer holiday/tour/journey anyway.but unlike some kits with care the rings can be re-used rather than replaced . less running in= more fun/speed =less worry.
