1. try service ur bajaj to shops such as tong aik/ah joo's which specialise in vespa. tink the mechanic just increase/decrease ur rpm.

2. mebbe autosol/wd-40 can do the trick? bike cover transparent?? i nvr see before in my whole life. only saw, blue, black, silver..

3. u can hang on the neck if u buy those iu with external battery. (e one dat has a cylinder on the side). or buy iu cover to cover the ugly iu lor.

[vigano]

decrease in power ... many reasons but sometimes due to contact point(since urs is an indian made bajaj),exhaust plug,carb dirty,plug prob etc etc ....

place to do ? recomend Ah Kau ( leong kah heng ) behind singapore post at payar lebar mrt ....

rust ? best u go to hardware shop ... look for "rust converter" ... but be aware it'll make the place black as it convert rust to metal ...

 

cheers mate

[Sharpey]

The best thing you can do is to spend some time getting to know your scoot. Do lots of research on the internet, and ask more questions on forums like this.

 

The ammount of stuff that I have learned during the past 2 years owning a vespa is huge... Now I feel I understand enough to make me dangerous....

 

Taking the flywheel off over the weekend to check the timing.... wish me luck

[edge-t]

Hey Sharpey, you haven't fixed the pinging problem yet?

I thought (Ah Kau) Leong Kah Heng have been forgotten. kekeke...

Address: Blk 1060 Eunos Industrial Estate. (Behind Singapore Post Centre)

#01-202.

 

He is 1 of the pioneer for vespas. Welding of body panels, spraying painting, welding of broken exhuast pipe etc.....

 

He is a person I respect him most.

 

Rusting part also can ask him for advice...

 

My 2 cents....

Hey Edge-T

 

I've not yet fixed the problem.... suspect its a timing issue there... When I finally get a 19mm socket that will fit inside the flywheel to get the locking nut off, I'll extract the damn thing and see where it's set at....

 

With a stock crank (cut or not doesn't matter apparently) factory timing marks can be relied on. The stator plate has two marks on PX's "A" and "IT"..... A is 23BTDC and IT is 18BTDC .... if its inbetween the two marks then it should be around 20BTDC.... I suspect mine might be at 20, but want to check... if it is I'll retard the timing to 18BTDC to see if that solves the pinking problem... if not, its either modify the stator plate so I can retard the timing further (pain in the arse) or get Mr Wee to put a spacer gasket between the piston jug and the top end to help reduce the compression....

 

Lots of fun eh!

 

 

Will keep you updated.

 

Ps... Vespatnt.com is a new site set up by some Aussie scooterists (with a similar climate to ours) where you might find some good info... including a forum (though it isn't v.popular at the moment....)

 

Cheers.

hey guys, thanks for the info !!!

yeah, visited VespaTnT.com a while back, it's a cool thing to do; road trip on a vespa. Wish I could do it...

 

Stock timing for PX200 should be at the "A" mark, yeah, 23 BTDC plus minus one degree, according to the haynes manual. So, if your's at 20, it's pretty retarded(pun intended, heh) right?

 

Correct me if I'm wrong, retardation causes the plug to spark later, letting the piston travel further up to TDC before igniting right? If I'm right, you should be advancing 'stead of retarding. Don't take my word for it, I hate timing the lil' bugger, and I can't remember. Hell, it's a load of fun! Fixing it is part of the joy of owning a vespa!

 

Better still, try stock timing first. Keep me posted! And loadsa luck.

[Sharpey]

Hey there....

 

Acording to the research that I've done... Advanced timing is what causes pinking...

 

Got the right tools together at last today, and sure enough, timing was set at 23BTDC.... too advanced given that I'm not riding a stock px...

 

Have set it to the IT mark, or 18BTDC and am waiting for the weather to clear up so can see if the probelm has gone away...

 

Cheers.

[edge-t]

Why do we love the vespa? Probably just some good marketing by piaggio. Here's a short clip on vespa, produced by discovery. Enjoy.

[hippo0]

haha,nice video sia..

 

anyway the ah kau oso do rusting for yr exhaust?

wht the price?

[un-sith]

good clip!

[ducatitan]

edge-t, thanks for the clip.

 

Anyone did this before?

[vigano]

good job Sharpey ... u know ur machine well ... for me, i learn from mechanics and books on vespas... looks like i can learn from u

[hansray]

Hi...i wanna restore my vespa like repainting, rewiring and add in some accessories....heard abt ah kau shop...is the shop gd?? ...

Yeah, saw that one before. A dangerous thing to do when you're riding in a group. Can't do a wheelie, need balls the size of durians to do something like that on a vespa.

[rae07]

hey guys...i think it's more appropriate for me to post question here than the other vespa thread.

i'm new to vespas and i'm riding a px150. feel that my bike losing quite a bit of top end. (can hardly catch up with vans on 4th gear.) was informed by previous owner that pipe's 'tong'. will it be possible to suffer compression loss due to a 'tong' pipe? if so.. how to rectify the prob?

haha, i scare i wheelie le den my bike fall and i cry cos have to pay and redo the things again..

ex u noe..

lols

[vigano]

ah kau ... do drop by the shop and judge it urself .... selling some stuffs other vespa shop dun sell ....

haha, i think the best time to "practice or try" is when u hav decided to repaint ur scoot, then one week b4 just keep practicing.

i haven wanna repaint..

but hor practice later oso will get hurt

hahhaa

abit crazy

[Sharpey]

Hey Vigano... I'm no expert man... just spend far to much time surfing the web and asking questions on forums like this... (The haynes manual is good too)

 

I figured the pinking problem at long last.... it was a combo of two things...

 

1) timing too far advanced at 23BTDC

2) scoot running to lean at idle... meaning that when coming off throttle on expressway a clicking/pinking noise is heard from the engine... this is because when you come off the throttle, you come off the main jet, and then the only fuel that is getting to the engine is via the carbs idle cricuit (controlled by fuel screw at the back of the carb)... This was too lean...

 

So I richened it up... and now the prob seems to have gone away... Will try running 95octane in a while and see if it comes back...., if not I'll advance the timing to 20BTDC (now at IT mark... 18BTDC).

 

The trouble with retarded timing is that you loose the 'zippy' acceleration... BUT bike can rev out further in each gear, meaning top speed will accutally be higher.... Personally not too bothered about top speed (100kmh is plenty fast) so will try and get the 'zip' back....

[Sharpey]

Rae07.... never heard of a Tong pipe... sounds like a fairytale to me....

 

If you've got a loss in compression you'll notice that the bike is much easier to kick start than normal....

 

You could get the compression tested just to be sure....

 

Perhaps though, you just need to get your pipe 'de-carbonised' to get rid of all the carbon that builds up over time and affects the flow of gases....'cos if you don't know when this was last done... its probably time to do it
