    !978 185 what fits.

    I see a lot of posting about the 84/85 motors and what they fit and don't fit.. What years fit the 1980 and older 185 frames I know 2 valve xr 200's fit, do any of the xr250's fit. I have a flatracker w/stock frame for vintage class and was hoping to put a 250 in it. Has to have dual shocks to be in that class. Do any of the old sl 250 motors fit this frame.

    Thanks but what are you responding to the xr250 or the sl 250 install . I have looked at the 1979 xr 250 and it looks like a direct bolt in,just trying to find out before moving forward. A little more detail or a web site would be appreciated.

    YZ250F bog and high idle

    Turn the idle up the 45 or the 42 should work fine your high idle problem is probably not fixed and the idle is turn to low and causes the hard starting this happen to me while trying to fix the same problem still haven't found the solution. An earlier post makes sense about the oring .

    high idle problems

    The tps throttle position sensor will cause that problem as was stated earlier in this thread did you try unplugging it.
  9. Bottom line with methanol you must build the motor to run on it or you will never realize the full potential of the fuel same with nitro methane been riding nitro hill climbers for 28 plus year. both are sensitive to weather changes. Methanol is great for a play bike but you will use 2 to 3 times more fuel in a day . more compression more power on methanol .....
  10. Is there some where to buy an after market piston and what models have the same piston. I believe it is 101mm. would be nice to have a big bore kit in it.

    carb question

    float is sticking. clean it.
  16. martym8

    Carb question?????

    yes it does but you will feel it more so up to 1/4 throttle . your bike miight not idle and it might stutter off idle. You will feel it when you get on and off the throttle.

    96' Ktm 620sx

    Ecellent bike very powerful handles well only draw back is the left hand kick . You can start it with tennis shoes once you learn the tricks...
  18. I beleive the slow jet is the pilot jet ... On the old twin carb models the jetting is very touchy sounds like you put a pipe on it so your jetting is going need to be changed. You can move the clip on these but you have to take the whole top off of the carbs and dig in.
