[QUOTE="mountain, post: 247239, member: 27629"] Well, I put the bigger 60/160 jets in my bike this Saturday.... WOW! I didn't think that the jetting would make that much of a performance difference relative to the other stuff that I've done lately (above). But I really think it made a difference in power!! More power, period. I think removing the snorkel and putting in the Uni made it more responsive, but I really feel like re-doing the jetting gave it more power.... Am I trippin'? More gas = more power....that I should be able to feel/ notice, right? The 60 pilot DEFINITELY helped w/ starting!! Where it used to take me sometimes 5-10 kicks to start my 400, it now started in with only ONE kick most of the time, and only 2 kicks the rest of the time. Even cold. NICE!!! Anyone else interested in doing this, it was EASY. Just print out Snaggle's directions above, and get to it. Took me bout an hour, and this was my first time doing carb work. One thing that I noticed that Snaggle didn't mention was to unscrew the throttle cable holder on the carb, THEN disconnect the throttle cables from the carb. This gives you the play you need to undo the cables from the carb. I'm sure this is a given, but this was the only thing that kinda stumped me... Bike is runnin SOOO good!! I'm gonna need a lot of rear tires now!! Thanks all for your input. Snaggle, since I mainly ride woods, trails, jeep roads, I really haven't noticed any big suspension limitations...DEFINITELY limitations on an MX track, but not really on the trails. I'm sure it's just ignorance. What would you recommend for upgrades? Just springs and valving? Will that make it rougher on the trails though? A guy that I saw that was racing an XR4 the other weekend said all he did was put heavier oil in the forks. Is this kinda "half-A**"? Recommended? Sounds like this is mainly for MX, and not really good for trail riding... Suggestions anyone for suspension mods good for trail riding, AND why you did these mods (limitations/ problems you were having before you did your mods)? Thanks again. [/QUOTE]
