Value proposition

Comments On Jul 23, 2014:Does everything the other standard screws do for a better price.
Tip was exactly the same shape/diameter of the factory item, and it comes with the spring/washer/o-ring.
Seems like Tusk products are a great bang for the buck as I keep gravitating toward them again and again.

Great Product But...

Comments On Jul 07, 2014:The only problem with the mixture screw is the spring needs to be longer,i installed it and had only 2-3 rides and it came out,somehow i found the screw a few feet from where i parked,i put it back in carb and screwed it in until it bottomed out and came back out three turns,it feels like it will stay but it seems the vibration turns it loose,the very next ride i lost it again and had to ride it back home without it and this time there was no finding it,if the spring was longer and would have stayed in i would have gave 5 stars but the spring is something that is obviously not strong enough to hold it in,other than that it looks nice and is easy to use but maybe it will be fixed with a better spring....still love ROCKYMOUNTAINATVMC and all there products

Great Product

Comments On May 31, 2014:Have used this on my 2004 Honda CRF250X for about 2 years and it works great. I don't often have to adjust the air/fuel screw, but this one makes it a snap since it is easily accessible. Works as well as the more expensive ones I've used on other bikes in the past.

Must have!

Comments On Apr 30, 2014:I have been having issues with the bike running right ever since I put in a new jetting kit. I did as the kit told me to but still didn't run right. The stock fuel mixture screw is a bugger to get to. But after having put this on, I was able to tune my bike much quick and easier. My bike was backfiring bad. I did some research and found that it might have to do with the fuel/air mixture. I got this and was able to adjust the screw while still riding up and down the street until I fixed my backfiring problem. Was awesome to do that on the fly. Love it!

Well worth the $

Comments On Feb 08, 2014:I have always bought these screws for my 4 stroke bikes if they didn't have them on when I got the bike. Saves so much time and makes tuning for the morning/afternoon so much easier.
