101 carb questions
-
Can anyone tell me what year the 28mm was introduced? Did the 26mm get used up till 96?
Has anyone else ever fitted a 28mm flatslide to an early 26mm roundslide bike?I apologise in advance cause I have probably more like 1001 questions.
My bike has never run properly. I have a 28mm flatslide that came with a 180 main jet. I recently changed it to a 210 and the bike wouldn’t run above 1/2 throttle! I was ‘read’ to believe that the main jet only affected the last 1/8 of throttle? That the bike should still run fine even without a main jet, up to 3/4 throttle?...
Also, when I let the throttle off at certain revs/speeds/throttle position, the engine actually picks up and accelerates! I’m guessing I’m gonna have to go back to square one with this. The head gasket is fixed with an Athena gasket, the bore and piston are sweet. I’m gonna check again for inlet air leaks. But if anyone has had these problems before, or has insight? Help!! 🤪

@declan
I only ask cause the Haynes says the TZR uses a 180 main jet. I’m wondering if a previous owner thought a ‘TZR’ main jet would be a good thing...I know the engine is good. I’m gonna put the 210 main and .225 pilot in all according to specs. Q2 needle valve and 5j25 needle. Make it standard for a TM28SS carb...
If I still have problems with anything above 1/2 throttle I’ll adjust the needle height. I don’t know what else to do. I’ve swapped out the reeds and cage to no improvement...
Wish me luck
Any opinions or advice is welcome...

@spookdog check your ignition circuit the whole thing from killswitcg to spark plug look for any corrosion or breaks in wires

The centre is usually a good colour, but it is only the very centre, electrode, ect. The ‘outer ring’ is always black and wet. No matter how it’s ridden. I removed the bottle top plug I have on the carb to filter rubber, to let more air in and the engine ran a lot better. Not proper but better...
