Hi revo1 and welcome to the best PB site on the planet. These guys are well informed on pocket rockets, and hey I'm kinda new myself. I have about 12 bikes, Giovanni's, Rossini's Zeimini's, and a brand new Star-X 50cc w/c C5 from Winnipeg in the Ducati style. All that mine was missing was a couple of windsheild screws. The gas tank was sitting on the pipe, so I put a few pieces of heavy fiberglass roving between them for insulation. Yeah the pegs are typical chinese wads so when the ends break just rip'm off and go with the stubs. Watch out for your boot on the chain, it'll rub. The rear spkt. is a 72 tooth and it goes good but likes to wheelie alot, so put a 64 on to get a higher speed and keep the front end down. There have been horror stories about the wrist pin brg. fouling, but I had no prob's with mine yet. Just break it in properly, take your time. Mix at 25:1 for the first tank of gas, let it smoke, it's a good thing, fire it up let it run to get hot(but don't rev the snot out of it, just rev below the clutch grab rpm) then shut down and let cool down to cold and do this 5-6 times before riding, and when riding don't push it all the way, just go 1/4 to 1/2 throttle for a few sessions then peg it, not too much though, and change the plug to a better grade in a while. It might over heat a bit in the begining but that's normal. Mine goes like hell now. These bikes are way more powerfull than the cag's so watch the throttle or you'll have some nasty road rash. PS for more info go to the "how to"s at the top of these pages good stuff in there.

Oh yeah, I was told that a Fiat Punto 1995 rad cap is a good replacement. And the reeds I don't know yet I just ride it and have a blast.

I checked out your pic's and I see your not new to this. Bless those super lucky kids of yours, geez.

Hey revo1, g'day, I'm just curious if Jason or Natalie has left you any feedback, It's been close to 3 weeks and they haven't left any feedback for me, dispite alot of asking and near begging. You got your bike on ebay, from outa Winnipeg, right, so did you get any. And hey do you like the bike or have any problems with it yet.

thanks for the welcome pegdrag!

about the feedback from jason ........pffffff promessed me part at low cost and never respond to my email
emailed him 3 times and no response back !!!
no feedback and no parts "%$/?&*)
i have noticed that all wheels have bump in it
i like those bike but want to know more about upgrads
been searching for 2 days now here in the forums but dont find nothing about bigger carb,porting and matchind and about black widow reed valve???

yes my kids are lucky one .........me younger one is 19 months old and did a small run on my new pit bike .........i dont believe it at all ,she just love it every minute of the ride
my older one (6 years old) is more affraid ,she has 2 quad and like it a lot
she also drive my traxxas revo 3.3 and she is really good at it
where do you live pegdrag and how old are you
i am from quebec and i am 35
i own a mecanic shop
see ya all

for the other help on modification of my c5 would be appreciated
thanks

sorry buddy, I must have skipped over this post some how...

blackwidow reeds, dont waste your money, get some simple fiberglass or carbon single stage reeds.

i'll start looking for that damn rebuild picture for the bottle cap but to be honest i would just get a real deal blata cap, blata.ca should be able to hook you up...

as for what can be upgraded / improved, that depends, first thing i would like to know is which carb did it come with? is it the 14mm dellorto sha with the flat slide and no needle? if so swich it for a 19mm dellorto phgb and you will see HUGH gains, next fix your squish, it comes set way too high you want it to be as close to .5mm as possible..

there is a free clutch mod that can be done which will keep the clutch cooler than stock, which will help it last longer and allow you to ride longer...

any other questions please feel free to ask and I'll do my best to answer them..

Hi revo1, I'm 52 going on 20,lol. No kids. Yeah about that twit jason in winnipeg,I just put a nasty complaint into ebay about him and his antics, I wish you would do the same, go to the "contact us" thing, or email them at support@ebay.ca, and tell them what happened or didn't happen, I'll get one more bike out of him. I might need spares.

We live in Kelowna, in the heart of the Okanagan Valley BC. And race at the local go-kart track(s). Our club (actually mine)is called the "Okanagan Pocket Rocket Racing Association"

Jeez yaknow I'll bet I was bidding against you for a bike(C5) at one time. My handle on ebay is dudrick55, what's yours guy.

As far as mods on the C5 go, haven't done any yet, still breaking it in, so maybe later when it's worn a bit. Do you think it really needs mods, my C5 goes like karazy man, coming out of a fast corner it want's to wheelie down the straight. Have to be carefull with the throttle not to go off & crash.

How's your C5 running? And I heard in here that a 1995 Fiat Punto rad cap will fit and work good. Just cut off the pegs and use the stubs.

nickj is good, he knows his stuff.

thanks nickj

the dellorto 19 mm replica ? is it ok
does it need ajustement after put it in
ajustable?? if how i tune it how do we do ..not familiar at all with 2 stoke

and what do you mean by SQUISH close to .5 mm ....not sure what it is

thanks again for all

is that ok 19MM DELLORTO STYLE CARBURETTOR CARB SET C1 C2 MTA4 - (eBay.ca item 330236894092 end time 13-Sep-08 15:10:06 EDT)

and while i am asking question i will add this one
how do i play with sproket SIZE
i know if i put a smaller size in front i will increase acceleration but what do i do with rear one
what seems to be the perfect set up dor mta4 50 cc ............ok ok 45 cc

thanks again

the replica 19mm phbg's seem to be ok, if you can afford the real thing this would be one of those times it would be worth it, some of the rep carbs are doomed from the start, but so far most people have had good luck with them..

if you buy the real one they let you pick all the inside parts (automizers jets needles) and one of the worlds best blata tuners has informed us on which pieces to pick to get amazing performance.. the replica carb will need to be setup after it has been bought which means more money..


squish is the space inbetween the piston at TDC (top as in as high as it can go) and the head, changing the (squish) adjusts your compression ratio, most of the china bikes come with +1mm or more on the squish which robs power from a motor that is already lacking compaired to the real blata...

the squish is adjusted by using a thinner or no base gasket, which brings the cylinder and head down but leaves the piston the same height thus lowering the "squish"..

and again you are very welcome...

stock gearing is 6-68 on c1's and i believe 6-70 or 6-72 on the c2's,
the front "pinion" will need to be bigger for more top speed, the reverse is true about the rear "sprocket" it will need to be smaller for more top speed..

they changed the gearing on the c2 because they wanted to be able to say it's faster, but I think 6-68 is pretty damn good gearing for a c1 or c2.

Hi guys, the stock gearing in my MT-A5A 50cc w/c better known as a C5, is 6-72 and it goes wild. But on a long track I'd need a 8-68 or a 8-64 for more top speed, I'm sure it has the power to handle it (8-64). It may bog in the tight corners but make it'll up on the staights. And I like it so much I'm getting another one, because it's alot easier to switch bikes than switch gearing, lol. Then I can mess around with one (performance parts) and ride the other.

Hey nickj, that 19 dellorto rep is the one I've put on my 53cc big bore cag (lil' Ninja) The one with the 20 ounce N2O bottle. tehee, and that is a very fast cag.(8-68) The carb is exceptional, and runs real smooth. I'd recommend it for the frugal PBer's. Not sure, but isn't the carb on the C5's a 19 mm? I haven't taken my C5 apart yet, just been riding it.

it's hard to say what is on it without a description, too many factory's making the "same" bike but with different parts..

pull the air filter off and look into the carb flat silver slide = 14mm sha rep, round black barrel + needle = 19mm phbg rep..

hi
hey nick about the carb 19 mm that i showed you on ebay:
what will i have to do if i buy it and put it on the bike .will it work
....sorry for all the question but around here no one seems to know anything about those carb neither pocket bike
they sells it and that is all


tommorrow i will take a brand new one in box and try a different gear and shave the head a little to begin


hey pegdrag i just e-mail jason for the third time since friday ......still no answer .....why he promise parts if he ignore buyers after receiving money

another thing about your bike pegdrag :
check you water pump pulley .i mount 3 bike out of 5 so far and 3 had the bolt loose ...very loose it could damaged something or strip and overheat


thanks


hey guys can you imagine that i bought a brand new m109r 1800cc orange 4 month ago and it sit in the garage since new(200km done ) and i am playing with 400$ bike instead of riding a 15 000$ bike

call me nutz !!!

yes, that one on ebay you showed is the right kit for the C1 style bike, main difference in the rep kits are the manifolds and that is the manifold for the blata style...

keep in mind the "Dellorto" jets dont quite fit perfect in all the rep carbs so changing the jetting can be a pain in the arse, also might want to ask about what jets / needles etc are in it and then compare it to the "trevor sellers" setup... then you will have an idea of what will need to be "added" to get the best performance out of it..

ps
Nice bike, I dont really like choppers but that one looks pretty cool!

Hi revo1, ok yer nutz, but hey me too, i just bought another bike from jason and payed the same price as the last one. Last 30 seconds bid won it.hahaha

I too have a 82 Kawasaki GPz 750 in my shed that i'm not riding because it won't start. two months now. I turn key and no lights or nothing. I was racing it in the 80's at Mosport, Shanonville, St. Pie and other tracks, but now it is retired in the Okanagan Valley BC. I've had it 26 yrs, also a 79 Kawi KZ1000 Mk II SBK not running, apart, old race bike too. Did you ever race?

Ok, I'll check my water pump belt and screws. It did get hot the last ride. Maybe something wrong.

You know what, we can here your accent in your writing. That's wild.

Did you get carb from jason or somewhere else? Is it a flat slide without needle?

Hey nickj, exactly, what is the "trevor sellers" setup?
