Yamaha blaster top speed

[Blasterzane]

yall keep saying the top speed is around 50-60. i have a full fmf exhaust kit, upgraded reeds, tors removal, and a new jetting set and mine will hit maybe 30 topped out and down hill. its not like im a large guy either, im 5'10 and 160 lbs. is there something im missing that will boost me up the other 20-30?

What size are your rear tires and what is your gearing ??
Also, are you shifting into 6th gear ?
Jetting good?

He's ask what the tire size is labeled on the tireand number of teeth on front and rear sprocket.that way he can see if its a gearing issue

Brand new air filter. Need to check compression runs great 1 thru 4. Need to take it out so I can run WOT.

Rear tires are 21x10x8

Are you jetted correctly for that pipe.maybe around a 280 main?someone here here will know the magic jet numbers on main.check plug color and main jet number before going wide open again.just to be safe.let us know on compression.exhuast sealed tight at cylinder?

Hey looking to buy new sprocket, chain and gear any name brand that that I can rely on such as volar, JT, renthal or OEM . Thinking of what size I need always want to go faster but don’t want to give up holeshot.
