new engine

[mealygrub84]

so was looking at getting a new engine for my xtm110 was looking at the gpx125 supposedly its one of the quickest 125 engines on the market but there is a zong 140 for the same price which would be the better option

 

[zwebx]

for price gpx all the way
if you wish to add on later on and get wild power go for a zongshen 155/160
if you want wild power now daytona 190
would not waist my time buying a 140 yx,lifan etc ever again there a dead end motor in terms of power in balance with reliability.

Daytona 190

gpx 125 for the win

 

[mealygrub84]

well if i had the 1400 dollars i would get the daytona but yeah 500 dollars max

 

[Blender]

yea, i understand dude, the gpx is probably the best value for money. stickj an oko and be done with it

 

[mealygrub84]

24mm or 26mm

 

[Blender]

probably a 26 for more top end performsance. go the 24 if you want bottom end.

if you want more power later there is a 4valve head coming out for them soon according to firepower minis

 

[Blender]

For the gpx's? that would be pretty sick! and also, have they only just started putting 4v heads on the yx160's? cos i saw one on ebay, i'll try and find it again.

thats the stock head, and a price of a stock yx 4valve heads are all over yx's and have been for a while.. looking at some disassembled pics of the head there not high quality and is not a uncommon thing for them to snap rocker arms, cause problems so i hear (or have perceived)
i would go a takey head every day of the week but the cheaper 4valve heads cost too much and need work out of the box to make the same power as a v2head of cheaper cost makes..

 

[Blender]

i see. so all the money spent on a cheap 4 v head, would be better put towards the v2.

well for 573.65 (aud from 00racing +arounf 100 shipping) for a 4valve with a 63mm bore you could get wayy more power and torque from a tb head with a 67mm bore and that should be enough power for almost anyone

i was running the gpx in my bike currently swapping it into my sons bike it is an absolute ripper mate couldnt recommend it more there quite simply is not a better bang for your buck engine out there.
