What were you wondering about magee?

kvakkkvakkkarl: No, I belive it is around 800.

Not a very good picture from Sverre, but you see the 40 Lectrons with 44 bore. Unfortunalety, I don't have any more pictures or graphs right now.

This is an almost similar engine, exept for the pipes (Tomcats) and head (I belive this is a short plug head)

This is very much streetable.

What rwhp is a standard bike showing on the dyno that gives this one 128?

Here is a picture of a article in the norwegian triples club mag, this purple bike have about the same porting/mods to the engine as the green bike.

You are a sneaky one Hal........

Dyno's are not all callibrated or set up the same. It can be misleading to make comparisons between bikes measured on different dyno's as some are a bit more generous and some are a bit pessimistic. Their best purpose is for making comparisons between bikes or making adjustments to a single bike to see what improvements are made, but all measured on the same dyno. The same bike might make 80 on one dyno and 90 on another one for instance, roughly speaking. The reading of a standard H2 on that same dyno will help put the 128 in context.
128 from a street motor is very impressive. My old school stage 111 FBG drag bike is making around about 133 on the dyno we use.

Hi Hal.

I have a dyno myself, a Dynojet model 150. Old type, but it is calibrated from factory. The drum has a , 4 digit unique calibration number. Don't know how accurate though.....

We are running around in Norway with our mobile dyno, and the greatest differences in hp and torque measurements comes from weather conditions.

I feel that air pressure is the factor which count the most. We had a 12 zx-14 on the dyno in foggy low weather pressure conditions in "high" altitude also. 189 rwhp. VERY impressing. Some days later we had the exacy same bike on our dyne, at sea level and there was sunny high pressure weather conditions. 201! Something is wrong we tought, and did a new run. 202. Another run: 202.

That should not be possible with a crank hp 210 incl. ram air zx-14!!!!!!!!

Anyway: The difference on same dyno, same bike 13 hp.......

EBOS has tuned several streetable H2's, and he is not considered nothing else than THE tuner! I have another friend with the 4.th EBOS -H2 in this thread, and taht bike gives 112.

Maybe he does something others don't, I really don't know. But what I DO know, is that there are many EBOS H2's around with that numbers I gave. And that does not mean it's false just because very, very few manage to do so.

The 127rwhp pictured above has also been on my dyno..............The numbers were high.

The purple H2 shown in the magazine above was on the dyno (your dyno) right after me on Saturday at the Norwegian Triple Rally.
Mr. Paulsen told me that they had a couple of stock 500s doing 50-51 RWHP on Friday which sounds just about right.
I did 66 RWHP with my H1E on Saturday and the purple H2 did 113 RWHP. He only got one run before he probably ended up friction
welding he's clutch release rods (if I remember correctly).
