Resync carbs while he's into it. ask for old jets back, set A/f screws, take a test ride before you pay him to make sure you have no stumbles in midrange of power band.

Did you already drop them off? If not you can save yourself some cash by doing it yourself. It's not that difficult.

I took the bike to him...I have NO mechanical skills and don't want to eff anything up. He is into it as we speak and it appears that the boots that connect the carbs to the engine are shot to hell and need to be replaced. Anyone know the specifics on these boots? I looked at bikebandit.com and they look like they'll be sold in sets...20.33 for one set and 11.87 for the other. Anyone with better suggestions?
Thanks
Thanks
Why the rejet? New exhaust? Which kit?

It's got the Jardine exhaust cans....but I don't know anything about it. I was going to have him re-jet because the bike came from Missouri and the elevation and climate are way different here. I'm not a mechanic...re-jetting was suggested by the guy I bought the bike from.
My mechanic found 2 things when he got to looking at it:
1) There was a switch that I was told changed the V-Boost from 5800 RPM to 3000 RPM....but my mechanic said that he traced the wires to the coil and removed the switch and wires due to having a short somewhere. The bike runs way smoother already.
2) The boots that connect the bottom of the carbs to the top of the engine are way cracked. I believe they are all 4 the same and they are part number 1151797 and $20.33 at Bikebandit.com. The guy at Bikebandit told me that they are sold in sets of 2, so I would only need 2 for a total of $40.66. The local shop quoted me $20.33 a piece for 4 of them.
I want to order the parts, but I want to make sure they are the right ones. I am also getting really antsie to have my bike back already, and it's only been gone for 7 hours. :-( It sounds like it will be in the shop for the next 2 weeks.....VERY SAD :-(

+1 to all the above. Float levels should also have been checked before removal. Make sure they're in spec when you get it back. Ask what height he set the floats at. Plenty of threads here on checking float levels. Welcome to the forum. You can find anything you need right here.

Given that you have a mechanic who knows his way around VMax's. The wait will be well worth it... Once these bikes run right and you don't let them set for any length of time, they're Rock Solid...
If you have to use Ethanol Fuel. Get a good additive to counter the Alcohols bad effects and stabilize the fuel... Ethanol goes bad fast and it absorbs water to an extreme....
Good Luck,

Have him check the vboost boots while the carbs are off. They usually go bad quicker than the other boots.

Thanks Steve-o....I'm Steve also. The reason he has it right now is because it had some midrange powerband stumbles. I'll ask him about the float levels, but honestly, I'm pretty mechanically dumb....

Thanks Grumpy...I run non-ethanol premium and I'll have him check the v boost boots. Does anyone know exactly what boots to buy so that I can just buy them and have them installed?
Thanx Mark, I went to Bandits and had the part number, you verified that.. Their Drawing really leaves a bit to be desired... 1 to a pack or 2, does he need to order 2 or 4???
Yamaha parts house shows qty 4 required @ $14.84 each

Anytime Dave. Go here for fiche....very clear.

You can order individually. He'll need four of each of both vboost and carb boots.

I agree with the extra octane not being necessary.
Star shows 4 needed @ $20.33... Thanx again Mark...
His dilemma is that Bandit told him the part came in
quantities of 2 per pack at that price. Each sounds
more correct...
