I got ya Nelly Nell I can see what your saying taking just amount of material off might cause catoshrophic failure with contact to clutch nut, I need to look at the bell again

That is why Lucas milled off some part of the inner side of the clutch to avoid contact to the nut. If you just mill down the center piece that has the splines it won't work because as you mentioned it would make contact.

To be honest, big job for probably not much gain. I use the HIT clutch as is with my stock clutch bell and the clutch pads come out like 1-2mm not a big deal if you ask me. The clutch still bites very hard and performs very good that way.
Unless you have someone that can mill down the clutch for you just leave it as is, just my 2 cents.

If you are trying to get the bell to fit closer to the clutch you may run into a problem. There is a "nub" that has the splines inside of it and that is likely why it wont fit closer. If you go too close your bell will make contact with the big clutch nut and its not good. No more slipper clutch, ask me how i know or am i misunderstanding what you are trying to do?

Thats what I ran into yeah. The bell ran into the outer rim of of the clutch base plate. It didn't hit the nut though I think (?)
I had to trim the rim down only slighly and in a way it didn't affect strenght or rigidity.

When it is quiet I start to get bored and start to think about improvements and here is where I need some help from you guys again.

I want to replace my current variator front face with a Polini Air Speed or the Polini Evo face with those white, plastic fins. I use the Polini Evo R02 variator and I think the Evo front face would be the correct choice but I worry a bit about those plastic fins.
I use the strap tool to hold the front face while open and close the variator nut and I'm not sure if that tool would damage those plastic fins.
Anyone with experience out there?

Second question is regarding pipes. I was thinking to replace the pipe on the blue Jog which currently uses the V8 pipe. Was thinking about a Yasuni again but this time ond that has a lower rpm powerband for better bottom punch for daily traffic driving.
Would a Yasuni Z be a good, cheap choice for a Polini Sport setup? Or maybe a Polini pipe?

[spaz12]

I had one of those Polini Air fixed pulley halves but don't remember anything special, or negative about it. But I tend to remember things more when they irritate me, so it was more than likely a good part. lol sorry not much help.

I have a feeling that some day you might get a bit better cylinder and so if you can afford the Yasuni R, it would probably be a better choice...

[tsimi]

Thanks spaz12

Nah, the blue Jog has to stay low grade 70cc sport for easy driving. The Yasuni R has probably a higher powerband and therefore I will have to get those rpms up like I needed to do with the City16 which is what I want to avoid. Low rpms with bottom punch is my goal for the blue one. And it has to be better than the V8 which I think is a bit restricting my top speed.

[spaz12]

Hmm, no clue then.

[niz76]

Non-expansion pipes are the best bet for real good low down torque, but of course you miss out on top speed due to the limited RPM's.
The other pipe that comes to mind besides the C16 for good torque and better top speed than a non-expansion pipe would be the ol' faithful Leo Vince ZX/ZXR. Of course they're not made anymore so it's getting a bit harder to find one. I think I read in an exhaust shootout somewhere that the Yasuni Z was extremely disappointing power-wise and especially for the price...

[Lucass2T]

If you want something between stock and torquey like Niz is saying and the Yasuni R i'd go with something like a Tecnigas next. I dunno any well designed pipes that focus on low end power...The Yasuni Z is probably the nicest of the low end pipes...but they have baffles inside which i totally hate.
ANyway, if you want torque it's either a stock pipe or some low budget low rpm tecnigas pipe.

[tsimi]

Thanks for the replies.

So we narrowed it down to

Leo Vince ZX or ZX-R
Tecnigas Next-R
Yasuni Z
Polini for Team...

The Next-R is really, really cheap and probably worth to try once for that price.
The Polini pipe was on SALE 2 month ago, too bad I missed that opportunity.
I have no access to Leo Vince pipes. The Yasuni Z looks nice of course but is expensive compare to the others.

Need to think a bit more about it....

What about the drive face? Anyone ever used the Polini Evo front face with the white plastic fins?

[Lucass2T]

The shot v2 is on or beyond Yasuni R level...thats more or less a 70cc pipe for low-mid rpm 70's.

[tsimi]

Ok, Gianelli removed from the list.

[tsimi]

Looking at all those Tecnigas pipes wondering what the difference between them is. They all seem to be entry level except for one, I think.

Next-R
Q-Tre
Trek
Triops (not entry level? ) looks very nice!

Anyone has driven those pipes?

[tsimi]

Interesting read,

www.pedparts.co.uk/blog/tecnigas-exhaust

Especially the part with the Yasuni R having a cone with holes welded inside it.

[190mech]

Lots of the lower end pipes have screens,baffles,perforated secondary cones..I feel they are all there to quiet the PING-PING of a tuned expansion chamber(I love that sound!) more than a 'special' tuning aid..All of these devices cancel the true workings of an expansion chamber,BUT they are all a heck of a lot better than a catalytic converter style stock muffler!!
