How would i get the most out of my brand new bike?

[DHZminiriderz]

So my Dhz dpro 140 is here and i was wondering how to get the most power out of it. I have noticed that when im fairly flat in fourth that it does not go as fast as i would expect it too and it has ALOT of vibrations. My gearbox is sometimes a bit skippy and i go from 2nd to 3rd it sometimes hits neutral. So i was just wondering if any of you MR Guru's would share some secrets on how to fix and improve some things. Remember im not the most technical person yet haha

well to be honest if you want more power now is a good time to upgrade the engine to a 160ho, it will have heaps more pull than your 140cc and when you get bored of the power of the 160 there are numerous mods that you can do it

the best mod is the V2 head as it has roller rockers, a high lift cam, bigger valves, and no this head is not available for the 140

Pbk is right the 160 would be the best mod for your bike, although...by the looks of it you have just bought it so while it maybe the best mod it may not be the most viable for you at this stage.

Without reading through your threads/post's what carby are you running? best bang for your buck would be a carb upgrade and decent tune and maybe a big bore exhaust also.

yeah i'd love to upgrade my engine but i dont have any cash at the moment, im only 15 so im not raking in the money. I am running a 30mm Mikuni carby

 

[MiniFighter]

Yeah i would love to upgrade my engine to a 160 but im a bit dry on funds haha, thats why i didnt just get the 160 from the start.

Yeah ditch the carb you have now and jump on the oko bandwagon!

OKO 26mm FlateSlide Race Carby Kit - DHZ Mini Moto

Its even on special atm..

 

[DHZminiriderz]

Would I be better off getting this carb? OKO 26MM FlatSlide Carby Kit, 1/8 Throttle, UniFilter, 140cc 150cc 160cc - DHZ Mini Moto just for the few extra things. Will i need to adjust the jets or anything?

 

[MiniFighter]

yeah you could, but as you mentioned funds were low..

Most riders arent fussed on the 1/8th turn throttle either, but the uni filter is a bonus for sure..

You will most likely need to change the jetting, not 100% sure on the best for the 140 but im sure someone here will know.

 

[sean01]

only the main jet...

they come with a 100 main you will need a 96

 

[DHZminiriderz]

yeah ill see how much i save up in the next 2 weeks or so. And i have no idea how to change the jetting, is it hard?

 

[sean01]

not hard at all.. look thru the carby thread and you'll see

 

[DHZminiriderz]

also, could this be used for some more power instead of buying a new engine? China Pit Bikes/China Performance/TB 160 Bore Kit - 124-140-146cc Engines - DHZ Mini Moto

 

[sean01]

can be but you lose a lot of reliability as the head gasket is really thin near 1 of the barrel studs/dowels..

 

[MiniFighter]

Not to mention the cost is nearly half what a 160 is anyways..better off just saving your $$

 

[DHZminiriderz]

yeah fair enough, i would probably screw it over anyway haha
