Pulse Adrenaline 125cc The Project Begins

[pac1982]

Any of you guys familiar with the Chinese dirt bikes also known as the GY series that use the 157FMI Suzuki engine?

I’m currently riding a Pulse Adrenaline and they come as a 125cc but some places have similar bikes that use the same engine available in 200 and 250cc and I’m trying to find some one who can supply me with a 200cc barrel piston and head.

My plans are as follows…..

200cc bore kit with matching piston and head

30mm Flat slide carb

Playing around with various sprocket sizes

Other non performance related mods planned are some gold Renthal bars and a gold Renthal chain, custom paint work in Jazz Blue, Projector style twin front lights and LED indicators

That looks like a Qingqi bike... Where are you located?

[AZ200cc]

Yup, Don't look like any GY I have ever seen...Nice bike.

[pac1982]

I'm based in the UK but dont have any problems with buying parts from over seas.

It is a GY the model number is XF125GY-2B

heres a few more pics

Is there a tag on it that says who manufactured it?

[pac1982]

Its made by Pioneer

[katoranger]

Possible to use a dr200 head and cylinder.

Allen

[pac1982]

Is that a "It may be possible" or it is possible??

[AZ200cc]

The motors do look similer, Small differances...Not sure if it could work or not.

[katoranger]

That would be a maybe on the dr200 parts. It would take some comparing to be sure.

These bikes are related to the Qingqi, but Pioneer might be an assembler of bikes using Qingqi parts. Or it might be a Qingqi. However, a good source of the Qingqi knowledge is member 'Forchetto' who knows alot of "stuff" about these bikes.

[forchetto]

It's made by Shandong Pioneer who are part of the Jinan Qingqi Group since 1995.

It's very close to the bikes made by the main factory with some differences such as rear disc brake, slightly different side panels, and the rear wheel hub and sprocket assembly is compatible with Honda CG and CB125's, rather that the Qingqi's Suzuki DR200 rear wheel components.

200 cc parts might be available in the UK from the people that supplied bikes under the names of Sinnis Apache QM200GY and Superbyke RMR200.

The bottom has dropped out of the 200 cc market in the UK, but those importers should have the parts you require even though they might not market the 200 cc versions anymore.

Sinnis UK, for example, still market the Blade 200 with that engine:

http://www.sinnis.co.uk/wp_products_tech_blade_200.php

Superbyke UK still has the RMR 200 in its site:

http://www.superbyke.co.uk/

You might find it difficult to put a flat slide carb in it, unless you can find an adapter with a flange bolt-to-bolt distance of 65 mm. In any case the bore of the inlet port in the head is only 28mm (200cc head). This is to suit the 28 mm Mikuni BST28 the 200 cc models come with.

The Suzuki DR200 head does have a 31 mm inlet port bore to suit its Mikuni BST31 carburettor.

I notice your plans don't include a different exhaust and yet this is what makes a considerable difference to these bikes. A cheap and effective mod is to fit this can from Xian Racing in Newport, Wales, UK.
Apart from the weight saving and increase in durability (it's stainless steel), it eliminates the restrictive catalyser built into the factory silencer, and gives a very worthwhile increase in power and throttle response. Sounds great as well...

See it here:

http://xian.west-wire.co.uk/index.php?act=viewProd&productId=58

A quick mental calculation tells me that the overall cost of all these mods will come to something like 50% of the cost of the bike, excluding labour charges. We know how much Chinese bikes depreciate...is it a wise move?.

Thanks for all that info forchetto that was a big help, so far all I’ve done is change the oil and fit a free flow filter.

I’m surprised how much different the filter has made it feel seeing as the standard air box didn’t look that restrictive, but with the new filter acceleration had greatly improved and hill climbing is much better as well.

I will be contacting Superbike or Sinnis in the near future to get prices on a 200cc cylinder, piston, head & cam although I’m not sure if a 200cc head will be any different from my 125cc version?

As far as carbs go I’m fairly sure I will be able to get a nice flat side to mate up and if i cant it wont be that hard to fabricate something. I’m a big fan of flat slides ever since I fitted one to my race tuned GY6 engine.

The sprocket set up is a strange one it would appear that the rear sprocket is indeed a Honda CG type set up but the front sprocket looks more like a Suzuki DR jobby

Anyways until i get some pics up of my progress on the Pulse Adrenaline heres a few pics of my last project which started off life as a Lambretta Pato AKA Znen Firenze AKA Lance Milan 125.

The Project included the following

Custom Paint Work
Custom Exhaust
170cc Bore Kit
High Compression Piston
Head Ported & Polished with larger valves
Up rated Cam
Prodigy Tourqe Driver
Prodigy Race Clutch
Prodigy Race Clutch Bell
Prodigy Teflon Variator
Various Tourqe Springs
Dr. Pully Sliders
Bando ECU & Coil
Gear Up Kit
Basic Nitrous Kit
30mm OKO Flatslide Carb with pumper jet
Performance intake Manifold

That Lammy looks the business... :P

The dealer should have the spares list and he can check up wether the two heads have the same number. They might be different in the arrangement of the Air injection gubbins. The 125 has the air port for the emissions gear on the head itself, but mine has it on the downpipe. Both can be blanked off.

The front sprocket might be a problem. I tried to adapt a DR200 Suzuki one but found the splines and method of fixing different. Aparently mine uses sprockets from a Suzuki TS125ERN /ERT /ERZ and even so they have to be machined to remove the centre part for it to fit on my Qingqi. In the end I just changed the rear one.

There's a post explaining my DR200 520 chain conversion cock-up here:

http://www.mychinamoto.com/forums/showthread.php?t=534

[pac1982]

What size rear did you go for and where did you get it from? also what MPH you getting?

I take it your bike is already 200cc?

[forchetto]

Mine came with 428 chain and sprocket combination of 15/48. Even before doing a few mods to exhaust and carburation this gearing was too low for road use. First gear was useless. I now have 15/44 and it's a lot more relaxed on the road and hasn't lost any noticeable acceleration. First gear can now be used and the top speed is about 115 kmh or if you don't mind looking a twat, 125 kmh getting the head down to the bars... :D

[pac1982]

Right well i spoke to Sinnis and Superbyke today and i got a bit of a mixed responce.

I spoke to Superbyke first who told me they could supply the 200cc cylinder for £140 a piston for £59.99 and a head for £120 but the person i spoke to seemed to think they wouldnt fit for some reason?

I then spoke to Sinnis to see if i could get the parts any cheaper but for some reason the refused to sell me the parts saying they would only supply them to dealers??

I'm also wondering if i will need the head and cam from the 200cc version as some people seem to think the 125cc version has the same head and cam as the 200cc

[frostbite]

Whitewalls on a scoot!. Pure awesomeness.

[forchetto]

Typical shortsighted attitude. They believe they're protecting their dealers, but all they're doing is alienating potential customers.

Here in Northern Spain we don't have a Qingqi dealer and I came to an agreement with the importer on the other side of the country, that he would supply me directly as if I were a dealer. He even sent me a price list and the prices inc. VAT at 16% over here are as follows:

Cylinder head 110 euros
Cylinder 78 euros
Piston, rings, pin and pin clips 41 euros

These prices are about a year old, but even then Sinnis seem to want far too much. I doubt he'll supply anyone abroad though.

[pac1982]

Thing is i am a dealer but just not a Sinnis dealer but i reckon if i told him that i would have even less chance of getting parts from them

I work for Llexeter Ltd which is Sinnis and Superbykes biggest rival, only problem is Llexeter dont sell the 200cc versions so cant help me out with the parts.

I have two goals i want to improve my own bike in the short term and in the long term put together a stage 1 2 & 3 performance pack for the Pulse Adrenaline as follows...........

Stage 1 = Pod Filter, Upjet, CDI

Stage 2 = Sprocket Set & Exhaust

Stage 3 = bore Kit

The pulse adrenaline sells really well here in the UK and there is a high demand for performance parts, prehaps you could get me some prices for a bulk order of cylinder kits and pistons?

[forchetto]

I'll ask them about big bore kits.

I wish I could get a CDI but there are none that I know of, and I've been looking all over the place, Chinese forums, Suzuki DR200 forums, ebay, etc. Nothing.
It's not the usual 5 and 6 pin job either, it's a larger unit with 8 pins.

There are are several exhausts about, but the Xian racer one fits without any pain, looks neat, it's light and sounds like Pavarotti when you open it up, yet it's reasonable in town:

There's a thread here dedicated to it:

http://www.mychinamoto.com/forums/showthread.php?t=499

Xian racer also do various sprockets for Chinese bikes and I believe have the CG125 dimensions.

JT sprockets have loads of them if you look under the Brazil CG125 and CB125 listings:

I’m currently riding a Pulse Adrenaline and they come as a 125cc but some places have similar bikes that use the same engine available in 200 and 250cc and I’m trying to find some one who can supply me with a 200cc barrel piston and head.

I'm not sure what prices are like in the UK, but a complete engine is more cost-effective where I live. As well, even if the cylinder and piston bolt up to the 125 bottom end, that doesn't guarantee 200cc. If the stroke is dissimilar, you'll end up with a hybrid. I presume that you're familiar with the math, but for those who aren't, the formula is:

(bore x bore) x stroke x number of cylinders x 0.7854

Obviously you have only one cylinder, but this formula applies to any piston engine to calculate displacement. I'm guessing that if you arrived at 155cc after all of that work (and cost), you'd be sad. Add to all of this that there is likely corresponding engineering in the 200cc bottom end (including the clutch) to handle an additional 75cc. What you're proposing is well beyond the typical big bore kit.

I'm enthusiastic about this project like you are, I'm just not convinced that you'd be as happy with the end result compared with a bolt-in 200cc engine.

Cheers!

[forchetto]

As well, even if the cylinder and piston bolt up to the 125 bottom end, that doesn't guarantee 200cc. If the stroke is dissimilar, you'll end up with a hybrid.

YOU'RE RIGHT...! :oops:

The 125 engine has a bore x stroke of 57 x 48.8 = 124.52 cm3

the 200 engine has a bore x stroke of 66 x 58.2 = 199.11 cm3

This means that the 125 crankshaft/conrod are different as well.

Thanks for the timely advice (and that formula!), probably saved us from costly mistakes.

[pac1982]

Even if i dont get the full 200cc i would still be intrested in doing it, when i did my GY6 engine i went from 125cc to 170cc which made a whole world of difference.

I see what your saying about just buying a new engine but over here a new engine will set you back over £500 but just doing the piston, cylinder and head wont be any where near as much.

I would consider an engine swap if i could get a 250cc+ engine that would fit.

[Weldangrind]

Even if i dont get the full 200cc i would still be intrested in doing it, when i did my GY6 engine i went from 125cc to 170cc which made a whole world of difference. You'll end up at around 166cc.

I would consider an engine swap if i could get a 250cc+ engine that would fit. I'd consider a Honda clone. The 250 dirt bike engines are cheap in North America, likely because of the volume. I haven't seen more than a few Suzuki clones, but I've seen hundreds of Honda clones in dirt bikes, quads, buggies, etc. It depends on how much fabrication you wish to do, and what it is worth to you.

no some 1 who had 1 of these bikes lasted 20 miles b4 engine packd in no bs
clamed they wernt ringing its neck
for spares try www.china-parts.co.uk
for upgrades try xain racings ebay shop or website
no xpert but it looks different to most gy engines (mines and lots of others) are old honda xl125 derived units i have heard from a dealer that these are suzuki ''style'' engines so dont no bout compatability of bits
