Thanks for that tip Tony! I was wondering if Lauro's plates would work on a standard ish clutch. I'm guessing you would leave off the oil thrower thingy as well?

Yeah... I would usually get somewhere between 45 minutes or 2 hours of proper operation out of any given clutch. I know Dayn shared my woes as well... I ended the season w/ a mad scramble of mismatched stuff just to finish the day. Somehow it worked just long enough - gave up as I rolled into the hot pits @ the end of the race. The prior month's race day I rolled in w/ smoke literally coming out of the clutch side of my bike. Max - I started w/a Malossi intake in the beginning. As I'm sure you've guessed, I had to manufacture a spacer (packer?) 12mm thick (could've gone a little bit thinner in hindsight) to squeeze the reeds in w/out hitting anything. It did involve lots of cutting, cussing, & crying, but seems to work to a degree that I'm pretty happy with. It utilizes a spigot mount from a really old broken MB (I think) manifold for a P series which would have taken RD reeds. W/a new rubber boot, the phb bolted up no prob. If anyone needs a good chuckle, I'll take pics when it comes apart in a couple weeks... ;D All of that being said... I'm still toying w/ the idea of a bigger carb ;D

paddy , whats a chopped and ported gsf style piston?

Max - I really was pretty impressed w/ the output on the Malossi cylinder after opening up the porting & incorporating the better reeds. Better reed design really does mean more power. For a relatively inexpensive kit to be modified & have that much better output was pretty cool. Especially from an iron jug. Tony - " chopped and ported gsf style piston?"...Sorry - I should clarify. GS piston - the coated kind, mildly ported to match the transfer rates of the Malossi. Chopped = milled the top of the cylinder to get my squish down to 1.2mm. GSF style porting comes from our friends over in Germany who can never seem to leave well enough alone ;D The following is more extreme than what I did, but... For example: This one is using a more involved intake manifold than I am. Mine still utilizes the base from the Malossi intake currently. Okay... I found a crappy pic of mine in progress from the summer... Mind you, this was by no means the finished product or a quality pic, but I would like to suggest that you don't need to remove as much material as the above pic in the interests of stability/longevity of use...? Who am I kidding. It's the race track.

paddy, maybe you and some mates should jump on a big tin bird in the sky and come over the pond to watch some of these looons in action over here...... if the youtube clips are anything to go by i think it will be right up your street....... ;D

;D It's true about the youtube thing. My lady thinks I'm bonkers - sitting about at night watching all the time... Even now; I'm actually in Brisbane Australia (it's fekkin hot) - taking care of family stuff. A few pints down, far from home, and i can't pull myself away. Still stewing away about my bike and the months of track events to come back home. I'd love, love, love to make a BSSO event (or even a German one as I speak a bit of theirs). Probably not in my budget for this year, but not outside my realm of possibilities for the next one. We'll see. Cheers gents. Be well.

Ha #67 is my old Allstate frame. It was stolen wrecked and sprayed then recovered. I sold it to a club mate who passed it on to a guy in Vancouver. I heard it was tuned and racing. Sweet.

someone's been busy in there. have you raised this barrel mate? The transfer windows themselves look fairly standard? Are they? Also , whats the 4 m8 studs doing poking out? For some massive reed block I guess?

;D That one isn't my barrel Tony ;D. Mine is the second (less quality)pic. The one in the first pic is just one that I was using as a guideline when i was cutting mine. The German scooter forum guys have a whole thread on modifying Malossi barrels: www.germanscooterforum.de/Vespa_V50_Primavera_ET3_PK_f14/Malossi_136_wirklich_t185542.htmlAbout half way down the page, the pictures get real interesting. I didn't remove quite as much material as these guys as I got concerned about structural integrity. I did widen my own transfers a little bit, and raised them about 1 & 1/2mm. I employed a Mazzy 51 stroke crank, so spacing the barrel was not really necessary as of yet.

This kinda translates it to English. However its not that good as at some point it translates something to '4 slices of chicken feathers' rough translation

A 1mm packer will only give you approx 124 trans . Race stuff is up around 130 onwards on these barrels. Ex around 190 on at 70%. You then can shorten the barrel on its top or spigot the head to bring at all back into spec.

Had a look on the german forum. Doing some mad stuff there.. bit optimistic on the hp figures mind you as a Falc produces 25hp. Dunno why they are machining away the 'land' around the gudgeon pin. Also dont machine the back end off the piston as they have. That area is a 'loaded' area.

Those bikes are Honda NSR50Rs. We have them on power but they can easily take us on the corners. The riders are 12 year old kids that have been racing for half their lives and are absolutely fearless plus they have the old power to weight ratio working to their advantage...well that's what I tell the boys at work when they laugh at me for being beaten by a 12 year old girl... lol ... it's all good fun!
