PATRICKJEWEL Posted May 10, 2018 Report Share Posted May 10, 2018 i got this barn find (1994 GasGas JT25 Contact) and had a lot of questions. what is the stock size in and out of the carburetor. Is there a aftermarket or other brand that will fit? Don't want to invest a lot, only bought for 100 bucks. Anyone know where i can find cheap part for the below list? Missing parts: Carberator Throttle and tube exhaust silencer Quote Link to comment Share on other sites More sharing options...
peterb Posted May 12, 2018 Report Share Posted May 12, 2018 Hi Patrick, the standard carb would be a DellOrto PHBL 26. You should be able to pick up a throttle assy and exhaust pipe and silencer from a long time GG dealer in the states. Bye, Peter B. Quote Link to comment Share on other sites More sharing options...
mcman56 Posted May 12, 2018 Report Share Posted May 12, 2018 If an original carb is not easy to find an OKO from Mid Atlantic Trials would be an option. I assume they could supply a throttle and tube also. Quote Link to comment Share on other sites More sharing options...
PATRICKJEWEL Posted May 29, 2018 Author Report Share Posted May 29, 2018 Do any of you guys know what bikes or years the engine was similar to another engine or bike. Quote Link to comment Share on other sites More sharing options...
thats_a_five Posted July 12, 2018 Report Share Posted July 12, 2018 The engine was basically the same from 1994 to 1998. There were different capacities 125, 250, 270, 321 over the years. Quote Link to comment Share on other sites More sharing options...
PATRICKJEWEL Posted July 13, 2018 Author Report Share Posted July 13, 2018 It says it was a 260cc ? Do you mean that the bottom end was the same but different top or just brakes, suspension, ect. Just got the head welded and machined back, had a pebble size hole blow out in head furthest from the flow tube. The reservoir for the coolant cracked and leaked out as the original problem. I am taking apart the bottom end now having to order a special fly wheel puller than what I have. Do you know how to get a service manual for this bike? Not just the regular purchase manual or do they have one. Quote Link to comment Share on other sites More sharing options...
lineaway Posted July 13, 2018 Report Share Posted July 13, 2018 Do a you tube search of Jim Snell gas gas video`s. The bike is pretty much basic two stroke, except the clutch pressure plate only goes back on one way. It is marked with a notch if my memory is right.
