Modern Buddy

Hi,
I live in Scotland U.K. and have owned a PGO G-Max 125 now for 3 years. They are great scoots and have never given me any problems. I changed the rollers shortly after buying it for Dr pulleys and also changed the variator to a GY6 teflon coated type. I get around 82 m.p.g. and a top speed on the flat of 56 m.p.h.
I wish we had the 150cc model here, but I could of went for the 250cc model, but at £1000 more I could't justify it. I prefer the G-max name as opposed to the Blur in the states, sorry guys.









Hope to add some input.

Welcome to ModernBuddy!

I love seeing G-maxes (I agree with you on the name) from other places around the world. Don't feel bad about the 125cc, though. If my suspicions about the Gmax 125cc are correct, you can get the Buddy125 NCY Big Bore kit and end up with a 161cc stroker engine (the 125cc engines have a longer crank with an abnormal wrist pin). Look into it, but don't take my word for it outright, it's more of an educated guess than a statement of fact. You'd have no regrets about getting the 125cc if that option is available. We miss out on the stock long stroke on the 150's, so for about the same price for our kit, we end up at 159cc.

That Ice Silver (I think that's what they call it) looks really awesome. I was never a fan of the Orange over here, but the black and grey looks pretty good.

Out of curiosity, who makes the variator you installed and what weight sliders did you use?

Cheers Bud, my Dr pulley weights were 13g and my variator kit was made by Prodigy sourced via Autotech on ebay about 2 years ago, also marked on the packaging is SR125 G3. The variator is teflon coated, can't say for sure if it made any noticeable difference, but the rollers did. Not many have this scoot in the U.K. and sourcing after market parts is a pain. I am a member on a singapore forum and they are very into tuning and modding the PGO, one of the guys has an uncle who sells them and gets all parts. I tried to get him to send me some service parts, but they wanted a substancial order to make it worth while, that's ok if you have a club with many members. The prices of parts in Asia are dirt cheap compared to our silly prices.
Your info regarding the big bore kit sounds interesting, I have heard of the GY6 big bore kit, but not PGO specific.
I also have the PGO manufactures workshop manual, must put it into pdf format sometime.

ps. just had a look on ebay and he still sells them.

Yep, they're all made over around there.

Here's a link to the kit again, double check that it's the same engine that's used in the Buddy 125 (BuBu 125 in Taiwan) first (I'm 99% sure, but we've not seen the 125 G-max around here).

We've got a few copies of the Blur owner's manual, parts and shop manual. I haven't gotten around to posting them yet but they'll be in the FAQ section, hopefully soon.

A lot of people put variators in at the same time as the sliders and notice huge improvements, but the biggest difference is in the weights. Don't feel bad about the parts situation, we're limited over here as well, lol.

looks good! i agree with the naming, i like gmax better. the blur just sounds cheesy. i guess it matches our Halloween orange lol

Great to have you here. Yes, love the G-Max name. PGO isn't bad, either. I was thinking the other day that a 161 kit on a 125 would be pretty sweet. I wish they made a kit for the 150. (Maybe somebody does). The G-Max/Blur is like nothing else out there. 125 or 150. The more I ride it the more I think I don't need anything else. I can not think of a better (and more fun) scooter for commuting.

It's a bit of a letdown compared to the Buddy 125 kit. Since the Blur has a 58.6mm stroke crankshaft (vs the 160mm on the Buddy 125) the kit gives you 157.51cc. So for $200 you get 8.01cc displacement increase. The Buddy 125cc gets 161.27ccs which comes out to 36.29cc displacement for $220. Talk about bang for the buck!

Keep in mind, this is all bolt in. I've been told that we can get away with 59mm without having to bore out the case, but I've not been able to find a 59mm kit that's ceramic coated (heat dissipation, longevity all around a good thing and worth more than .5mm in bore diameter).

Also, consider how much some people are willing to spend on an exhaust, CVT components, ignition, etc just for a little more quickness. One of our local Blackjack riders had this kit put in and he tells me there's a definite difference in the mid-range. Displacement does wonders for power. Most of the stuff that folks (myself included) do to their bikes revolves around how the power is delivered. A lot of that had to do with the absence of available (or at least trusted) engine components. We are, as Babblefish once put it, in the Scootering Stone Age here in the States.

Now we're starting to see some actual parts show up that can increase the power outright.

Vroom-vroom, man! Welcome to the Scootering Iron Age! Or should that be Ceramic... ?

Does your's have the digital cluster? It's hard to tell in that last pic.

No digital cluster, but from what I've read they aren't that accurate, that's why I have went with the trusty cycle computer. They do look the part though.

Which cycle computer are you using? I've been meaning to put one of those on for a long time now, but I keep forgetting.

Lostmycage, I'm using a Sigma Targa computer, very accurate as I test it when approaching the radar on entry to 30mph zones and it reads spot on, I get the same reading with my car and it has a digital display. Some areas around here are out by about 1-2mph.
On another topic, managed to jot down the number stamped on the transmission casing it reads: C1M H00874, hope it can be modded.

I'll chime in that the Buddy 150 kits will fit the 150 Blur too, they'll get you 176cc with a stock crank or 183cc with the stroker crank option. They're not on Scooterworks's site yet, but they're in the dealer catalog as part 1100-1270 for the jug, and 1100-1015 for the crank.

EDIT: I'll totally agree with the scooter stone age comment.... I STILL get nearly all my parts from Taiwan.

Just an FYI: that kit requires machining the case, . 59mm (or 58.5mm with ceramic coating) is the largest that goes in without having to cut the case, from all accounts that I've found. Also, if you're thinking of that kit, I'd get the crank as well. You have to split the case open anyway for machining

Thanks for the info on the bike computer, Irishrover. Kaos (via email - thanks man!) just found in the G-Max service manual that the 125cc Gmax is a 13mm wrist pin. So the Buddy 125 big bore kit should work for you. It'll get you to 161ccs. I think you'd enjoy the extra pep

Correct, they do need a bore, though I've heard that some of the older 150's can go bigger than 59mm without a bore. This may just be hearsay though.

Only one way to find out

Lostmycage, do you have any links or info on how to carry out this mod?
I noticed scooter assassins do a kit Link, but I had a nightmare experience with them before and am now banned from buying form them, they don't like you questioning their service.

Anything like a walk through would be second hand coming from me. There's a few folks who have installed this kit themselves, let's see if we can get them to chime in here.

Irishrover,

I've done the NCY/Scooterworks kit and have had great success with it. I also added the stock 150 head to get the benefits of the larger valves. On a Buddy 125 the kit can be done without removing the whole motor from the bike. Not sure about the G-Max though. It is in fact pretty much "bolt on". Not hard if you know what you're doing. The performance increase is awesome. More power across the board. It'll increase your top speed a bit, but REALLY increases how fast you get there.

I highly recommend doing this mod with the 150 head also. That big intake valve on the 150 head adds so much. Plus you have to use a different gasket between the cylinder and case with the 150 head, so if you put it off til later (like I did) you have to tear the whole thing back down if you want to upgrade to that head.

djelliot,
that sounds promising, how much more top speed will I get as on the flat at the moment it maxes at 56mph? I assume mpg will be slightly less.

ps. notice you have 11g sliders, I opted for 13g. Do you notice a distinct difference in performance?

I was getting stuck at 62 (actual) until I found out my stall spring was to long and wasn't allowing the drive plates on the clutch to open all the way. I put in a shorter stall and was able to peg the speedo. Haven't GPS'd it yet.

The 11g sliders I think are a good compensation for acceleration and top speed. I had 10g's for awhile and they were great off the line but a bit hindering on the top.

I can't say how much more top you'll get, but I can say you'll get there a lot quicker.
