Dyno chart - MEGA rich!!!

[VFR400+]

What size are 115 & 118 jets in terms of millimeter. Gonna order some new ones from wemoto, as they're pretty cheap so will rule them out. Im guessing its not as simple as 115 - 1.15mm?

aye, it is a measurement. get some from any local bike shop - they are all the same animal.

Dunno if its wishful thinking but it does seem a tiny bit less smokey but still seems to smoke

what colour is the smoke ??? , if its got a blue colour its burning oil , white is normal on start up but should clear unless head gasket problem , black smoke is down to major over fueling .

if its burning oil or over fueling it could be fouling the plugs hence the power loss .

Have you had a look at the dyno-graph on page one?

Goes off the charts rich from 4k onwards...

What needles are in it? Are they seated properly and not raised?

Cheers so I take it that these would fit http://www.ebay.co.uk/itm/BRASS-MAIN-JE ... 336a69f2ff

Ill get 2 x 115 and 2x 117.5 and Ill get some ditigal verniers and have another look at the floats.

Just out of intrest would the power figure from the dyno be at the wheels or crank? I assumed crank it would be a crank figure. Also anyone know the rough % lost through chain/sprocket?

At the wheels...seeing as it was on a rolling road and not an engine dyno bench.

bad luck on the wrist..

Well been riding for the last few days after fitting so R. Oliver jets 115 and 118s it seemed fine to begin with and ran well although today it was defiantly running rich again. When I fitted the jets I checks all the floats and they were spot on when I finished.

Have standard needles and I think they are still have the extra needle, Although I've got a feeling I took them out to put them back to standard.

Are you measuring the 2.25 turns on the A/F screws from fully screwed in ? And have the carbs balanced properly ? What size are the pilots ?
