These are re-branded high speed pistons. Good stuff. Not recommended for road use as they're single ring items.

Mr Pang Yao Yew's pipes are still made by Ah Hong. :D Specs a little difference (according to himself). Cheers

Nice collection of stuff.

Actually to be honest, I don't think one had to go to the degree of engineering work I did to achieve similar results. I'm confident of utilising primarily stock T135 parts modified to achieving somewhat in the region of -20% or so in performance. Doing what Im doing as an interest; as a pet...

Haha its oversimplification. As I've said, there's a huge science and debacle over this very topic for ages. Tons of info are floating around. Lotsa yadayada. But main thing is how to apply this into your engine design. A fuller explaination for those interested which I had (quickly) nicked...

Its a lengthy topic. Too boring for most readers I'm sure. I've briefly talked about this I think. Ha.

4sthead is good if you know how to make full use of it. Very powerful. Again, they're merely tools. At the end of the day, its the timing on the LED that appears at the end of 1/4mile that counts (or for that matter, circuit results slip). I'm sure you guys wouldn't believe me if I say that...

On a mildly tuned racebike I worked on (64mm piston), I'm revving it in surplus of 12Krpm. Peak power at 11,000rpm. Fierce? hehe Could've gone higher. Rider can't ride it properly in the track cos the power only kicked in at 8,500rpm (and goes rocket till 12krpm). I really don't suggest using...

Hi, I don't do the feet/min way. But there might be something wrong with your maths. • The stock stroke LC/Sniper/T135 has a MPV of 25.5m/s at 12,900rpm. • If the crank is stroked with a 3mm pin, it'll have a MPV of 25.5m/s at 11,750rpm These figures are considered the safe peak rpms for...

Kwang is the BEST!!! Support HiSpeed!!! :twisted: :twisted:

What's a low cam? :shock: :shock: Why would you prefer a low cam to a high cam?

Hey bro You rock too! Yeah, those were the dayz.. You take care. Catch up soon. :twisted:

This is an Aprilia RS125 item. Not Aprilia RS250. Cheers

Oh lord. Many things have happened while I was away. I miss rebuking Mr Rockies claims. haha. Goodluck to all that had bad relationships with him.

WOW! Titanium block of this same size (not to mention the steering tube!), CNC machined and only cost US$450??? Grab it guys! ITS A STEAL! Buy it and resell it as scrap titanium, you might even get a profit out of it! :lol: Anyway, as far as I know, no one in the market makes billet cnc...
