When you say use daily...have a think about the roads its gonna be used on..do you get the chance too thrash it for any length of time? or mostly 2nd/3rd gear racing between lights?..could be a factor in the kit you go for...and as for anyone saying waste of money/bad idea too change/tinker/hopefully improve and personalise your ride too what you like...id tell em nicely too funk right off....works for me...go for it LOON-E Thank you Loon! I ride my P2 daily to work and back and the odd weekend out. Normally doing 50-60ish on the roads I go down.

Hi,
im thinking of buying a 125 PX from a local Vespa/Piaggio dealer. I'm wanting to learn more about the mechanics of a Vespa so therefore I'm thinking of adding a kit to the Vespa. Only problem is, the only mechanical thing I've done on a Vespa is a carb rebuild. I don't really want a rusty project. I'd use the 125 daily until I gathered money for a kit and add over the winter.
Some people may say it's a bad idea or waste of money but, that's what I'm interested in doing. Have to start somewhere.
what are your ideas?

Which pilot jet did you have in there if not a 55/160? Did the old pilot jet have a hole in the top, like the 55/160 has? If it's a slot head screw it may have the 55/100 as H pointed out. Meaning it has not had the air feed hole for the idle jet filled with lead shot and then use a different idle jet, such as the 55/160. So you're saying the tap , when in the Off position, has no problems shutting off fuel. That should rule out the tap And if the body rocked a little that's not too good. Ideally you should sort that out with a sheet of glass, some wet n dry and some elbow grease. Check the fuel line for any signs of leaks from the tap or cracks Upjet to 120 Replace air filter (with drilled holed), or upjet some more Wear some earplugs! hahaha None of that will solve your dodgy float but will get you running better later on. A quick check to see if the float needle is sealing sufficiently is to take the float assembly, hold it upsidedown and blow through the fuel inlet hole in the centre of the chamber. You'll need to seal where the banjo/fuel pipe fits. The needle should still seal the hole and the float should not move despite you going blue in the face. Which tap do you have fitted? or is it still stock? I should have the 55/160 tomorrow or Wednesday so will be putting that in soon. The tap to my knowledge has no problem turning off fuel. I've left the tap off when the scooter had started and it seems to cut it off. The body rocked a tiny bit.. Is that still bad? I hear people use the glass for the cylinder heads too? What's the wet n dry? Will order a new air filter. Do you recommend buying the filter pre drilled or drilling yourself? Will give the check a look tomorrow.. If I can get a better understanding on what to do with it.. Yes the the tap is stock. Everything's stock accept the SIP Road 2. I was unfortunately stupid enough to leave the petrol cap open and tried kicking the scooter off and petrol went everywhere on the scoot.. I moved the scooter this afternoon to see a line of petrol coming from the exhaust. Kicked it off this morning and it started, bogged down unless revved.. Looked underneath to see a small puddle of petrol Sigh...

Have you taken carb off scoot? - Yes 2. Did tap hold fuel when you did that? - Petrol was in the off position 3. Did you strip carb as those videos? - I followed the advice on the video 4. Inspect for wear and free movement of moving parts? - All parts looked fine? 5. Replace needle valve? (with red tipped one?) - Replaced with brand new red tipped needle 6. Check float for leaks? Free-movement? - Brand new float replaced 7. Replace internal carb gaskets? - Replaced all gaskets with carb kit from Bees speed 8. Blow-through jets (all three?) - I blew the main jet and am replacing the pilot jet with a 55/160 9. Blow through all channels? - Not sure what that is.. 10. Check carb body for flat underside? - Body was fine, rocked a tiny bit 11. Bolt all bits back exactly as they were? Alldone 12. Check fillet screw still holding carb box securely? 13. Use a new Carb to carb box gasket? - Yes 14. Bolt carb bolts down evenly to correct torque? - Yes 15. Use two new fibre washers on Banjo? - 16. Check fuel line and banjo clip? - Didn't check fuel line or clip.. (Unsure what to look for)
18. Reconnect throttle cable and make sure it was moving freely? - Moves freely 19. Replace filter and screw down? - Air filter? I don't run one atm 20. Put your Idle and Mix screws back, either as they were before, or to standard start-point turns out? - Done, to standard 21. Make sure all carb rubber grommets were in place (including main lid one) before screwing lid back on? - Done

Thanks for the links Sime.
I think there may be a problem with the carb. I think the needle is stuck? There seems to be fuel coming from the exhaust? Now it won't start

stick with the bh7 es , for a p200 , unless planning on sustained high revs motorway work . H Do you recommended the long thread or short? Mines a long. Trying to find a 55/100 pilot, can't seem to find one.

stuck choke , hard to start warm,if not impossible ,clouds of white smoke from over-fuelling .or a scoot thats starts from cold easily without using choke an runs til hot then dies at tickover an wont re-start . stock on a p2's a 55/100 , an ive only ever changed a main jet when switching to a sip road ,left the rest as stock. H I'll try a 55/100, the main jet I'm using now is a 118, stock 116. I'll also try a new plug as I'm running a 7, I was told to use an 8.

hard starting when warms often a too large a pilot jet/rich mixture ,or sticking choke . when ya bump it does it pop n fart then "clear its throat" an rev . H I wouldn't say it would Henri, no. What would be symptoms of a sticking choke? (Accept hard starting when warm) I'm not sure on how I'd figure that out.. Could you give a small introduction too it please? Also what pilot jet would you recommend for a P2? (All stock apart from SIP Road II)

Finished the rebuild and went out on the scooter, all runs fine. Same problem as before still, scooter won't start after it's been ridden. Rode it maybe two minutes down road, switched off and tried starting and nothing. Will bump start though. Any ideas? Stator? CDI dying? Starts fine when cold..

My mixture screw is just a flathead?

Post by jellerby on Aug 4, 2016 16:22:11 GMT
How many turns out is the mixture screw in the back of the carb? Just checked, I'd say half a turn out maybe a little less than half. Isn't it supposed to be two and a half?

Can you do a short description of what happens when starting it? And a short list what you have already tried? It starts 3-4 kicks but doesn't idle unless throttle is turned. The idle screw doesn't seem to do anything. Tried it with petrol on and reserve. Im thinking of taking the main jet and blowing it out along with idle screw

When you say tightend 1 nut..if its 1 holding the carb on..they both need too be on and tight or your gonna be sucking air as soon as she strikes up...and will die LOON-E I only untightened one of the nuts holding the carb down and as I couldn't get the other one. I tightened it back up and put it choke and fuel line back?

Attempted rebuild, missing tool has stopped progress. Attached fuel hose again and tightened one nut down and attached choke. Attempted to start and now dies every time.. I don't know what to do now unfortunately

Thanks for the vids Johnny, planning my rebuild either tonight or Wednesday night. I've been out running on it today, I've ran in on reserve as it doesn't cut out. Any ideas? It's also idling very high, even when I turn the idle screw down a little, it idles high at stops..

I was riding my scoot and all of a sudden it cut out, started again and cut out, it's hard to start at times.. Am I right thinking it's the carb? I'm planning on doing a full carb rebuild. My first time rebuilding it

Planning on removing the filter and sticking a 120 main jet back in along with the SIP Road 2, see how it goes. It won't be running without any filter though. Should I buy one and drill holes above jets?

Post by jellerby on Jun 29, 2016 17:22:47 GMT
I have the 140 main recommended, just haven't fitted as of yet.
Not sure on how to check the circuits, never done anything like it and I'd rather not mess something up..
It's about 2 hours from where we are leaving from.

Apologies for all the questions about my scoot. Recently added a SIP Road all running fine, upjetted. Got 70mph out of it, slowly dropping to 55ish.. I've also added a Polini air filter on. Haven't upjetted to the recommended 140 main though, as of yet. Changed my spark plug from a 9 to a 7 a couple of days ago, now getting 60mph out of it.. One problem is, I can't rev out of the 3rd gear.. 4th doesn't have much pull. New spark plug made some difference, less kicks to start (I hope) and slight improvement on power. My thinking is the carb isn't set up properly or..? Also recently changed fuel filter in the bowl.. Maybe an air leak somewhere? Worn piston rings? Everything running fine accept the 3rd gear not revving out fully? Only a week or so till Cleethorpes, hoping for an easy, understandable fix..

Standard P2 with a SIP Road 2 exhaust, 65mph, one day 70mph again 60 and now my max speed is 50mph?? I haven't messed around with anything. 120 main jet, I ran a rubber ring around the carb box and now taken it off. I haven't had an air filter since I've owned it. I have a Polini air filter waiting to be put on..

P200 starts first or second kick runs fine, switch it off after running and it won't start until it cools down?

Post by jellerby on May 31, 2016 20:50:09 GMT
So what's the difference? I own a P200 MotoVespa MK1, I know it's a Spanish. Is there any difference in parts? I'm thinking of buying a new horn cover for mine. I'm looking at a PX/PE series 1 model. I don't want to buy parts that aren't going to fit. Any other differences in them?
thanks

Thanks Henri. If I drill the filter why would I need to upjet? I'm not sure what the main jet is actually used for really, I know it needs upjetting if the exhaust is changed. Is it so the engine is getting more fuel? My carb rubber was split so it wasn't connected and sealing the carb properly, what are your thoughts on that? I've put a new one now but does it make a difference?

Recently put a SIP Road 2 on my P2, running a 120 main jet. I'm thinking of putting a polini air filter kit on it soon. What do you think? I'm not looking for another 30mph.. Maybe just another 10 if I can. I don't want to kit it as its all stock accept the exhaust. Is there any cheapish mods out there? I'll say a budget around £150 or less.

Hello,
I just bought a SIP Road 2 exhaust along with two main jets, 118 and 120. It will be ran on a P2 all original and stock. My question is, is it hard to change the main jets? I've never done any engine work on my Vespa. Do I have to remove the whole carb to get to it? Unscrew or pull out? Any steps on how to change it is appreciated. Also, how do I know I'm running the correct size main jet? Plug colour?
thanks a lot

Thanks for the advice Henri, appreciate it.
I bought it for £1500 Loon so around £1400.

Thanks Henri, I heard they're a good engine. I really like the look of them too. My stock P2 only does 60mph so I wanted something a little faster, I'm saving for a SIP Road 2 exhaust for it at the moment.

I'm thinking of selling my stock P200 Mk1 and buying a stock T5 MK1. Are they hard to come buy? How much do you think it'll cost? Cons and pros?
