Thank you for this nice week end ! Lulu, Romain "Baguette" and I, had a lot of fun with you guys. Keep rocking !

Thinking to the way to shorten the inlet of my W-force I found a YZ 250 inlet on google with the fixing holes very similar to the original one. + It has a small curve to get closer to the side panel. Has anyone tried it or something similar ?

TOP !

I have exactly the same problem, when I'm at low rpm and throttle at full gaz, the scooter has "Stottern" and it seems that I have also this behavious in curves. My setup: Polini 177, Si24 55/160 160/BE3/132, si24 original smmimerdeckel/ 2,2mm hole in the vergaser , Sip road Maybe the 2,2mm hole is too much, the DRT has 1,8 accoding to sip.. ?

Hello, I wonder what Magura model is this ? Any feedback ? http://www.scooter-center.com/product/7676540/Brake+master+cylinder+MAGURA+Radial+piston+11mm+rhs?meta=7676540*scd_ALL_en*s934393145952*magura*1*1*1*16

Ok, and what diameter should I do ?

Thank you for the answer ! Are thoses holes the 1,8mm holes they are talking about on sip ?

Hello, I would like to use a cosa Schwimmerkammerdeckel on my PX177 because I have problems on voll gaz on the highway. My actual setup is Polini 177 ajusted / Si24-24E 160/BE3/138 and 50/160 with a sip road. How come the cosa model sell by DRT and Pinasco are so expansive, are they necessary or can I use a standard cosa model ? Thank you.

Hello, What is the minimum clearance I need to have a correct running ? Right know I have between 1,8 and 2,2mm between the last disc and the bell. I have a 0,5mm spacer behind the christmas tree and I have one more that I can add if necessary. Greetings.

I would like to use the Runner tree on the left on my engine but there is a misalignment in the 4th gear. Is there a way to correct this ?

Hello even with another primary it doesn't work, the springs don't stay in place when I remove the 2 screws.. Anyone has a tip ? With a bit of dremel in the casing would it fit all together ?

Dammit ! The answer is in front of me, I have machined the primary for the DRT repair kit, so the housing in the primary is bigger than is the Hartz plate and bell... so it is a pain in the ass to mount it, I'll try to find another primary gear to check.

Hello, I need to mount the primary and the repair kit alone in the engine casing ( the bell doesn't pass), but it's very touchy to make the springs fit, so I can't imagine in the casing. It's very hard to keep the spring in place when I remove the two screws. Do you have a trick ? I use DRT spings.

Wow ! Geil! Any pictures of the exhaust ?

Well...nice job ! The transfert in the casings are not even matched with the cylinder ? And you kept the flange inside the transfert ports ?

Then WOOAWWW Great !!

51 stroke ! ?

What does that mean ?

Hello, for a race use, I would like to use a longer 1st and 2nd, is it smart or not to combine it with a DRT runner christmas three with its shorter 3th and 4th ? I'm afraid that the gap between 2 and 3 would be too short ?

I'm going to add a piece to block the rotation like on the following picture, right now it's just fixed with the upper bolt of the U clamp.

Problem solved temporarily

Original VS SIP... WTF ???!! Not really P'N'Play

Allright but do you guys change because of the carburetor size limitation of the Polini or also because of the position of the carburetor ? I mean, does the carburetor fit correctly in the frame with the Polini ?

Hello, is it obligatory to use the falc intake to mount le carburetor correctly in a PV frame ? Are there pictures of the assembly ? Thanx !

Still on development , all the advises are of course welcome, right now it's just an original casing whith the standard thickness, crankshaft room, bearing. The transferts are bigger, and of course, as you can see there is an access to the gearbox.
