Went crazy with the grinder and now it sits just perfect. Belly was touching down in lefthanders but thats ok now. Silencer still hitting the panel but I got one of them spacers on the way. Ja valmis

Yeah, its going on a dyno, but not before June. Thought it would be interesting to see what its like with a huge rotary inlet. If Im not happy its pretty straight forward to grind away the sealingpad and fit a big reedinlet.

:) Dont worry, time for the sandals is on its way. Need to correct myself on the timings, its 135/191.

Here´s a handy clip of the first test run. Carb not jetted and ignition just bolted on. Mhr 1, koso34, rotary 130/70, 60mm, 131/195

I put in a 50mm shock extension an dit go ta bit better but still hits the panel when I (95kg) bounce on it. I´ll order the angled piece from mr.Fox. As a sidenote I got it all together and took it for a spin. Holy shit, its really powerful. And the ignition and carb is just bolted there. Had a issue with mrp bolts beeing too short causing an airleak, but thats a different story. Lara is top quality and the exhaust sound is really nice. Sounds mean.

Lara on SS Fits good, only issue is its hitting the left panel when putting weight on it. Though its sitting lower than std now because of Malossi shocker. Should be sorted with longer shock extension.

Hi guys, Which speedo cable for pk xl2 front end and SS/Sprint speedo? Thanks, -n

Thanks, I´would be very happy to make anything around 30 with the rotary Mhr I built. Well see in June when I get to the dyno. Its a Mhr1 std 60 stroke 130/70 rotary mrp 36 inlet koso 34 131/195 Lara, very nice quality btw.

Good result. Rest of setup? Port times? Thanks, -n

Hi, I replaced my Polini from my Polossi with the MHR. Timings with 60hub ohne fudi 186/129. Thought I´d give it a go with the ovalised SI24 and Silentbox220 2. Cant compare with the Polossi. As timings suggest its weak in low revs and when it would like to take of it feels like it would need a bigger carb and better pipe. Planning on a 30mm carb. Do you think the silentbox will work at high times as these or do I need a pure racing pipe? Thanks, -n

Hi guys, Just upgraded carb from koso pwk34 to a genuine Keihin pwk33. My 133 09M1LR is running on 127/188 with a Franz. Any tips on whereabout to start with the jetting? Thanks, -n

Good evening gentlemen, I bought this ratty primmy earlier today and gave it a wipe with aceton. Out comes this babyblue that looks identical with the blue ´67 V90 I have. The PV is a ´80. Havent seen a PV this colour before. The late ones we get in Finland are usually red. Anyone seen a late PV in this colour before? Cheers, Nicklas

Hi guys, My Polossi is working well and has about 6000kms on it since last summer. Im happy with it but I think there is more power waiting with small adjustments. I´d really appreciate any tips in what direction to look next. The setup is following at the moment 124/176 65% x width 186 inlet timing 120/66 ovalised si24 sip road 1.2mm squish Came out 18.3hp on the dyno, unfortunately I dont have the graph available now but I ll post it when I go by the garage. Unfortunately no revs on the graph though. On the same dyno a bolt on GGPolini 221with Sip road was making 18.1, so I feel that mine should be pumping out a few horses more..? I would like to keep the original look -->Sip road, but would be ready to loose the SI if thats what needed. Appreciate any advice. Thanks , NIcklas

Thanks guys. I was in contact with Olli before I ordered the piston. Unfortunately the demand for oversize pistons is so small that a batch wouldn't have been possible. That's why I went the px piston route. I was thinking in the same lines as Mathias. What I am really after is tips for the actual welding. Do you need any special rods or will the conventional Ali weld gear do the job on piston material ? Things like that. Cheers -n

Hi guys, Im working on a SS-208 conversion. Now I´m at the point where I need to get the hole in the PX piston filled. Its a std size GrandSport piston for the px200. The guy who is welding it is an ali welding professional, so not worried in any way but if anyone has got any pointers they are all appreciated and taken in consideration. Vielen Dank! Nicklas, Finnland.

So everybody agrees on the 0.215 piston-bore clearance? Rebore on friday.

If 0.215 is for px 200. shouldnt the SS have bigger clearance? Atleast the hundreds of SS´s in Finland are know to be very prone to seize. -n

Thats nice. I´ve sen those pics before. Here is something similar. http://www.curareracing.com/71501/51601.html After the rebore the cylinder lining will be 2.3mm thick. So no room for any boostports, I´ll open up the transfers in the base and match to the cases. How wide did you make your x port? Is your motor reliable? How many km´s have you got on it so far? Thanks, -n

The hole is welded on the piston. Of course the transfer exits will be smaller. I´ll clean them up after the rebore. I was thinking about extra boost port but the wall thickness will be so small so I dont think there is metal enough.

Hi guys, Im building a 208 conversion at the moment. I am using a GS 66.5 piston(PX). What clearance should I have it bored to? Thanks, Nicklas

What would be an good starting point for spark advance on a polossi with sip road? The engine is running now and holy shit what kind of torque! Very nice. What would be a good gearing for fast highway driving? I would like to cruise at 100km/h. Im at 85kgs. Thanks, -n

Genietet. Hier meine ´65.

I see. I think I´ll have a go with the the ball shaped bit and go at it from the base up. Whats the quality of the nicasil like in the quattrinins? Does it chip easy?

Thank you sir. I have the papergaskets under it now (.3 and .4mm), so should be able to the transfers down. The 1.2 squish will also allow this. Whats the best way to reach the aux xports with the dremel? Everyone cant have 90deg angle pieces..

Guten Abend, Im looking to get a bit more from the M1L 09 cylinder I have. Its now running a 54/105 crank 34mm koso franz 127/188 The gasket face is milled down and the barrel transfers are opened up. The motor was dynoed in Norway on wvd and made 22hp. There was a M1L 07 with 28mm, Bullet150, 127/189 making 25 hp. I have seen graphs here of 27hp motors. Heres a couple of pics of the xport now, what should be done to it to get the last horses? I was thinking of something in these lines, what do you think? appreciate any comments , Nicklas
