Hey guys...tommorow my lc is going on the dyno and iwas just wondering what kind of hp a stock lc makes a t the rear wheel for comparison..my bike has small can microns...doubled base gaskets raised port timing and halfed head gasket...air box mod as well....the dyno is a dyno pro unit as opposed to a dyno jet and apparently the pro reads 10-15 % lower than the dyno jet..any and all advice comments welcome...

im guessing 45bhp at the rear wheel for a ypvs,tbh it depends on a few factors like is jetting spot on,is compression good,are the pipes free from carbon,what the air is like on the day of the dyno as i can imagine the same engine will perform better on a cold damp day over a hot dry day.
from new ypvs f1's were 59bhp,f2's were 62bhp and brazilian R's were 59bhp
4lo was 45bhp and 4l1 was 35bhp i expect these figures are at the crank not rear wheel,hope this helps simon.

..so the mechanic mounted the microns and set it up..took it for a quick ride(really wet out so never hit 100km/h) called me and said it felt really strong...thats when he suggested dynoing it...so end result is 40.19 rwhp! I am really stoked as this is very healthy considering whats done to the bike..once again this is a factorypro ec997 so add the 15% its 46 rwhp on a dynojet....however the dyno tech has not shown the mechanic the graph yet only spoken to him on the phone as hes sick and he did mention that their was a bit of a flat spot between 5000-7000...so mechanics gonna take it for a hard ride when its dry..(hopefully today) and get back to me....once i get the graph i will post right away...anyway..any thoughts, comments or advice welcome.

 Well heres the dyno chart...flat spot was resolved by leaning out...1 clip size up...pulls like a freight train now and sounds unreal through the microns....all the issues i was having are gone and i now understand what power band crazy means. .....hey,does it ever become possible to hit 7000rpm and not whack it open? Now to start making it pretty! |

Depend on the dyno too, they all read diffrent by a good few bhp, also depends how good the operator is and if they set the ambient temperature right. Fact is i could make a Honda CB100 make 100bhp at the wheel for a printout. Just forget the top bhp figures and get the bike running spot on, thats the best thing a dyno is for to be honest.

If I remember it was a little better in the midrange Thanks, that's what i was guessing. Very similar looks to both pipes. Nice power from an LC motor BTW.  |
