I have just put a 44 tooth sprocket on (now running 16/44) and although pleased with the gearing there are quite a lot of vibes coming through the pegs.

I think it is because the wheel alignment marks on the s/a are inaccurate and now that the wheelbase is shorter the inaccuracy is more pronounced. Does anyome have any tips on aligning the wheels to find out if this is the problem?

thanks in advance

paul,

there is a thread in the mille section about string-lining the bike which gives a link to a couple of sightes about wheel alignment.

hope it helps.

the motor is turning higher rpms now due to the lower gearing!

also, the swingarm's adjustment marks are casted into the form so everyone has the same reference points.

I thought it was the higher rpm to start with but is all the way through the rev range. Maybe the new sprocket isn't true?

the lower gearing will affect all gears through the total revrange. as before, you were running some 200-400rpm less so you will have more vibs migrating into your body now from the bars and pegs.

you will have to live with the change until a taller gearing change is made.

the tuono had the same gearing as the mille, so tall that mille can do some 165+. the tuono feels like its leaving the planet at 160, and feels more at home around 150 and lower.

they mount both ways, but work only on way. any sticker on it?

that faces out 99% of the time.

the flange fits towards the engine with the spring washer on the outside.

one way to check it is to look at your rear sprocket and see if it is wearing on the outside a lot.

Excuse me for butting in as a lurker.But if none of the above works it may be worth checking the rear wheel balance in case it's changed for some reason.
all the best to all.

no problem scary, anything is posible, definitely check the real wheel balance, sometimes its the simplest things.

Thanks guys, checked the sprocket and the 44 stamp is on the inside. Doh!

If the chain is too tight it will also cause some weird vibe's..
