9 out of 10 times, when I blip the throttle I get the expected rev increase. However, 1 out of 10 times, when I blip the throttle, I get a ''fart''. Like a ''poof'' sound and then nothing happens, no rev increase.
Anybody have a clue as to what this can be. The bike is new (to me) and I barley put 1000 km on it. The bike is a '98 and had 35K on the clock.

Thanks

Search for 'fart' ;-)

Haha...my transition from inline four to v twin has not been a great one unfortunately. Difficulties with blipping the throttle and handlebar / foot peg vibration are making me question if a twin is really for me.

Carb farts fo sho. Lol!


Nice ava!!!

If you did a search it's quite common for the carbs on the VTR to fart occasionally - you can lessen the occurance by balancing carbs, setting the TPS and making sure idle is set at around 1200 so it doesn't readilly stall during low speed corners. Considering these are the largest carbs on a production bike they do a very good job of converting fuel into big grins.

Stick with it and ride the torque while playing tunes on the musical throbbing pipes!

Why blip? Plugs loading up? I don't blip and never fart

That is how I learned to ride and have always done it when downshifting. Matching the revs for a smooth transition to the lower gear.

jscobey

that is correct! its good for the gear box as well as making for a smoother let out of the clutch


like has been said, its just something that comes with BIG carbs. but shouldnt be the "norm"

tps, idle, and balancing will help a lot. also if they are dirty, a good cleaning will help. also make sure your jetting is correct.

Blip to match revs with the next lower gear so you have a smoother transition when you let out the clutch. More important when riding at higher revs. Brake, match revs with downshift and enter the corner smoothly. I'm sure there are better explanations on the Sport Rider website and elsewhere on the web.

I get that and bring R's up when running hard and down shifting, of course. Thought you were talking about sitting/stopping and blipping, not a fan of that.

Better check that bike with a torque qrench. Motor mounts etc. Especially if the bike is basically stock. Thick rubber covered pegs, really shouldn't feel a thing. I don't get vibes at the grips either, maybe pulse would describe it, nothing unpleasant and nothing like a gsxr thats for sure.
