Have you guys had or have this esp kit?
I bought that and boy i have had so many broplems with it.
Or i wont say the kit is the broplem, but everythin are doing this mix..
I had first normal zenoah crankcase and i used cy +2mm crankshaft in that, and this kit..
So i thought that it should rock like a star, but boy i was wrong.
First test film for my esp kit and it was 30,5cc on this film and i had fluid-rc pipe..
Like you can see, there are now low end power at all...
So i thought that it was because this kit was not mented to be used with this +2mm cranshaft i bought normal lenght crank.
But i had still low end power.
I also think that maybe that pipe wont work well with this porting, and i used jetpro v2 pipe..
No change at all.
So i bought dominator v2 pipe what is famous for it´s low end grunt...
Well i had much more low end power, but it still not run like it should.
One of my friend told me that i should check the clearance of my engine by using tin wire.
You do it like this.
Take off the plug, use 1,5mm or 2mm tin wire and make a L to the wire.
Put it in to the cylinder, so tha the end of that wire reach to the cylinder wall.
Gently pull the pull starter so that the wire will flatten between the piston and top of the cylinder.
Now measure that tin wire with a digital caliper.
I had 1.2mm clearance in my engine with stock 28mm crankshaft and this ported kit, so there is no way that there is
right compression ratio in my engine.
So what i did, i took off the gasket and i put hylomar seal between the block and cylinder.
This how i managed lower my compression ratio, and there was no only 0,7mm clearance between the cylinder top and piston.
This is how it took off after that modification....
In tarmac it was like a old turbo charged volvo, when the turbo took the spinn, rear tires was burning rubber...
But, there was still lack off low end..
So what im going to do next is..
Im going to buy 29mm (+1mm)crankshaft, ans play that clearance, or also called squish to be 0,45-0,5mm with this.
But boy it has took me a lot of time and made me even balder than i am now...
So even those cylinders are came from factory, what these different factorys are doing and porting, can be a huge different´s how they work in different car and engine...
For now on, i will always do a check with a tin wire how big the squish is...
So every one who is going to buy a new ported kit or even stock and want to get all the power out of it, you should measure clearance of that kit and block...
