50mm Big Bore Elite S Build

[Wheelman-111]

Greetings:

Thanks for giving me my props for the Band-Aid "solution". Be advised that Taiwanese Band-Aids are reportedly "rubbish". Go with Hello Kitty all the way.

[Trafficjamz]

Since I could not find a hello kitty band aid, I decided to replace the piston.

I got a different piston this time around.
The original was a rik piston.
The new one is not

I put the new 50mm piston in on monday......it did not fit.

The piston skirts are about 1/4 inch too long!

Time to get out the magic stick!

If the rings are good I have a 50mm RIK piston with nothing else. You can have it. PM me. I am suprised you did not PM me in the first place.

May I suggest you go a whole lot bigger on the Pilot? (58-60) The Lean-Is-Mean Main at 150 sounds small, too, but if you're just going 1/4 mile it should foster best performance. However when you close the throttle at the traps, that 50 may not keep the now red-hot cylinder cool enough.

[Trafficjamz]

You could remove them reed springs, that'll take a little tension off the reed petals.

Why do this?

bump that pilot to a 55 or 58 at lease.with the 9.8to1 gears run the 90/90 tire. for your drag setup up the compression and run race gas c12. your 60ft times will get way better.

I have switched to a 90/90 tire
My 60ft is about 2.4 sec
I will switch the jets as soon as they come in the mail.

Traffic, I am building up something similiar, and i am going to drag race by the end of July as a goal. By the looks of that GPS, you were rolling out!

How are you doing on tha goal?

[Trafficjamz]

Can anyone tell me which clutch is best for drag racing.

What belt is best for dragracing when running the ZX trans conversion?

[Trafficjamz]

I got a polini 2 puck adjustable clutch and I like it alot.

I also switched to the ZX trans





When bracket racing, it really help keep times very consistent.

Drag racing season is now over for the year.

So check out my new build Superman 2 (Now with full stroker) comming soon
