MOPED ARMY

wait. you are saying your hitting 49.5 mph on the flats on a stock cylinder? what kind of bike?

better yet how big was the hill

im on a garelli ssxl

stock piston stock cylinder

11/25 gearing

techno estroli

21mm phgb with a 20mm intake

but i did no porting or anything .. no hill at all.. i just ran out of road and couldnt keep going .

wow u must have no torque what so ever but have fun :P

I am interested in this phenomenon. It seems that when engine cases are matched for kits with large transfers, and then the stock cylinder is put back on, these engines tend to perform feats normally out of the realm of possibility for stock cylinders. To me, this meshes well with what Jennings says about transfer ports, which is that you basically can't make it too big where the transfers begin in the case. The bigger you get, the faster it goes. You're only limited by how much case you have. I think further improvement could be seen if these stock cylinders had their transfer openings matched to the engine cases (which were already modified to make them match a large kit).

I predict, here and now, that if you put a stock cylinder on cases matched to an 80cc metra, and then matched the transfers on the stock cylinder to the case, we will see the highest speeds every seen on a stock cylinder. This assumes, of course, that the transfers on the case don't extend beyond the outer edge of the cylinder block on the stock cylinder (where the cylinder block stops and the cooling fins begin).

Wow, was any of that readable? It's getting too late at night to be writing.

I'd say its possible, but I dunno, I'm skeptical, especially with a 21 and 20mm intake just thrown on there. No matching at all? Those gasses don't like running into walls.

My korado cylinder has done 45 with a 19 phbg and simonini. Yea its not really ported yet, but the intake matches and the exhaust is aligned. It could probably do faster with more gearing, but then its not practical to ride under 25.

Does 50/50 count if you bike hits 50 when alll the stockers are already several blocks down? I don't think that should be the case. Mine does 45 and beats pretty much all of my friends bikes off the line. I know I would be destroyed by any of the good kitted bikes on here though.

If I recall correctly, Harold's 50/5o magnum ended up blowing at latebird rally. By the time he was up to speed he was already dusted. I'm pretty sure shaw's 50/60 bike is up there with the best almost the entire time. Correct me if I'm wrong.

i believe you drew, i mean your probably not even real?!

I think 50/50 is an awesome feat. Anyone who has done it shouldn't be poo-poo'd. Who cares if it has bad low end. If it does have good low end then more bragging rights for that person

Harold's bike was fine off the line btw. He had some other problems but all and all that bike was pretty sick.
