I used all oem carb screws for the first two years I had the bike, although they were soft and did round out a little they will hold up if you're careful. I suggest purchasing new, better hardware but I just wanted to share my belief that they will last more than one or two teardowns.

 

Yes, a small pair of needle nose vice grips and I got all the screws out and replaced them everytime with stainless steel allen heads. Work great and never again have that problem.

 

When you go to a dealership for maintenance their labor costs are based on some kind of chart that tells them how long it takes to tune the machine. It's not a matter of just taking off a couple screws, removing the jets and installing the new ones. They have to make sure the thing runs right before they give it back to you. Jetting is a trial and error procedure. If all you wanted them to do is take the screws out of the carberator and give you new screws that is what you should ask for.
Everyone knows the screws in the carberator are very soft and strip out easy, but would you rather strip out a screw for a few cents or strip out or cross thread the carberator and have to pay many dollars to fix it.
I'm not backing the dealerships, for the most part they are a bunch of crooks. It's best to find a good independant small engine mechanic that works on bikes. There are a lot of them out there and they need our business.

 

The first thing I do is get a screwdriver that fits the screw perfectly,then make sure it is in the screwhead and hit the screwdriver a few good sharp cracks with a hammer and very rarely does it fail.If you use stainless steel screws in alunimun you need neversease because they react with each other and corrode,now try to get them out, I didn't mean to bash you, sorry if I came across that way.

 

very true about stainless and vegtable erh i mean alumanin just becarful thats all

 

If I were you id just take it somewhere else and have them jet it. I can do most work on my bike but jetting to no avail is my weakpoint. when i did my exaust and intake on my wolverine I did the installs myself then rolled it on the truck and brought it over to a local garage and had them jet it. (the two brothers who own the shop have been racing cars and motorcycles since the 70s so they know what they are doing.) find a smaller non-dealer type shop that has some experience with smaller engines. anyplace that works on motorcycles. they jetted for me for 45 bucks and worked fine for the two years i had it like that until i had to rejet for my wiseco piston and white brother cam. I never go to the dealer anymore Dont know where you are from but I go to a guy who works out of his house and does good work for much cheaper. he builds grass drag sleds and motocross dirtbikes for people all over newengland. Sometimes a degree in mechanics is one thing but experience and knowledge does it in.
