did someone know something more about this anomaly

did someone know something more about this anomaly?-vfr 1998 110 ks 781ccm vfr 1999 98-106 ks 781ccm,vfr 2000 110 ks 782ccm ,vfr 2001 108 ks 782ccm.or 47.66 cubic inches ,2000,2001 47.72 cubic inches 2002 781 ccm or 47.66 ci

is is true that vfr 2000. and 2001. had more ccm or cubic inch than other models vfr 800???

 

I'm almost sure that all VFR 800s have the same displacement (cubic centimeters). The 6th generation bikes got v-tec and cam chains, but I dont remember reading about any displacement changes since they went from 750 to 800 cc.

 

I know everything about VFR but I find this informations on www.bikez.com and when I look in my papers I see 782 ccm.

 

I doubt if Honda would change its bore size ,crankshaft stroke,or connecting rod length from year to year. I believe all 5th gen. bikes have the same displacement. Guys think about it, Honda isn't going to retool from year to year. Car and bike manufactures like to keep the same pieces from year to year to save money, now every once in a while bike manufacturers will do a redesign of a motor, then anything goes. eddie

 

I know that, I'm mechanich. But maybe they something change in head or place of valves or something in expansion chamber???

Maybe is some change because is 2000. was 50th anniversity of honda??

 

Just look at the Honda part numbers for the block, pistons, connecting rods, crankshaft, etc. If they are the same then there was no change for sure.

 

I think it was just a round up thing and a type-O

 

I studing a litlle bit model 2000 and 2001, they had a lot of little changes...

I doubt that is changed bore size but knowing honda everything is possible ;D

 

will the 2002 crankshaft match my 1999 Anniv model engine?

This is really important. I have the 1999 Anniversary model with the Red, yellow, silver theme. It is supposed to have 8bhp extra and all I can find on ebay is the crankshaft for the 2002 model.
So, two questions, anyone know where I can get the exact crankshaft for my model?
Will the other model crankshafts match my engine? I will prefer not to try the VTEC's though...might have been changes in alloy components.

 

Yes. Honda rounds up. Their " 800" is actually a 781 or so

 

Bike show here in Sydney, Australia last month: the VFR 800 was listed as having a 762cc engine.

 

here ya go. 2007 manual. sorry for the poor quality. (bought in the good ol' US of A)





middle right... 782 cm3


they are cheating i know... lol i guess our 800s were really just big boned 750s all along!

 

All 5th & 6th Gen's have the same Bore & Stroke, the head (nor any other parts) are NOT taken in to consideration when sizing an engine, the official designation is "Swept Volume" so all ot these engines have the same Displacement or Capacity. The discrepency almost certainly comes from the conversion from CC to CuIn rounding up or down error.
