700xx question

6923 Views 37 Replies 7 Participants Last post by  Billy250X
I have been looking at a 09 or 08 trx 700xx at my local honda dealer and they have dropped the price from 7899 down to 5899 now and I have been thinking about buying it. but i have some questions. First would this be a good sport quad to go trail riding on? and how does it do in tight trails? the trails I would be riding on would be forest service trails, would the big 700 do good for that? or should I stay will my 250ex until it's paid off and then go for something else? thanks in advance.

yeah I'm going to play hardball with them for sure cause I would really like to get this quad. but im just not willing to pay a 9% interest rate to get it. i'll build the damn thing myself piece by piece before i will pay the 9% interest rate. cause my 250 was a 10% rate and i got screwed on that one I think anyway what size jet will i have to got to if I take the airbox lid off?
What main are you using now with the hmf?
right now i'm running a fmf DJ106 main jet with the hmf exhaust system.
HUH?It should have a number like 125 or 122.It must not be a Keihn jet.Go to the honda dealer and buy real Keihn jets or go here.Jets R Us
no it's not the honda brand of jets they are from a fmf jet kit that I bought. could I use the jets out of the fmf kit that I have? cause the number on the fmf jet that would be in the carb now would be 106
Well 106 is way to low if the numbers are the same as the Keihn.A stock 300ex runs a 118 and the 250x runs a 122.
well the jet that I took out of my 250 when I done the exhaust has k90 on it.
Wait wait wait.What kind of quad do you have?I'm sorry I forgot you have a 250ex.Sorry.You should probably have a 100 or 105.Did your fmf kit have a variety of jets?
yes it has a variety of jets I have the 106 jet in my 250ex now and then my kit has a 110 jet in it and then a 096,088,092,102,096 that's all the jets that are in my jet kit.
Try the 96 and the 102.I'm really sorry I thought for some reason you had a 300ex.I'm stupid sometimes.
billy, which jet would give me the best power with my hmf sport exhaust that I have and then taking the lid off the airbox. also my elevation is 5980 or something like that it's almost 6000'. and can you explain how the numbers on the jets work is it the smaller the number the bigger the hole in the jet or how does that work? and thanks for your help.
Yeah the bigger the number the bigger the hole through the jet.I can't tell you exactly what jet but being your 6000 feet you'll be running out of air.So deffinetly remove the box lid and you'll have to try each jet.You said your stock was a 96 right.Just start right above that and work your way up.Once you think you have it find a long stretch and wind it out in 5th gear and I mean wound out.Then shut it off.Don't let off the gas or pull the clutch in.Once it shut off pull the clutch in and stop.Pull your spark plug.And see what color it is.It should be of a light tan or brown.If it's black it's rich and if it's white it's lean.Good luck.
All quads are jetted for sea level from the factory. For every 1000 feet you go up in elevation, you go down 1 jet size. So being at 6,000 ft you need to go down 6 sizes from stock. From that point go up one until you have smooth acceleration through the whole RPM range.
ok thanks for the help guys, will I have to have a new spark plug in my quad to be able to tune it or can i use the plug that's in it? I will try it this weekend, so I need to get some smaller jets also right? thanks so much for your help.
No your jets should be fine man.And the plug might help but it's not manditory.
ok thanks again guys i will try it this weekend. thanks again.
Yep no problem.Thats what we are all here for.
