McFear,

Your pilot jet is clogged and by putting in a richer main jet has over come part of this problem.

I bet it is hard to start and has some hesitation off idle and the idle is inconsistant.
And my guess is you have set the idle high to get it to idle.

If you turn down the idle till it near stalles then turn in the mixture screw and if the engine keeps running
and the mixture screw does not make much difference that shows the pilot jet is clogged.

Just go by a new pilot jet ( 68S ).

Do you know the proper way to adjust the mixture screw ?

cheers mate,

will buy a new pilot jet,

i think i do, i read about it on the pig pen.

if i take the baffle outta the pipe, will the 180 jet be more suitable or would i be better suited putting the 175 back in?

Yeh i would go back to the 175 main jet, the engine will be more responsive.

Have you downloaded the genuine Honda manual for the bike ?

A tip is too to set the float height at 16mm not 18mm as the manual states.

In regards to the stock carby, it has to be tuned richer than a pumper carby,
easy way is to keep turning out the mixture screw until the flat spot dissapears.

dropped the bowl again today and checked the pilot jet, its not blocked. but it is a 65, not a 68s. i asked at honda for a 68s and they said the only thing they could order was a 68, which i reckon would be better then a 65 but they knew nothing about a 68s.


so if i go back to a 175 and replace the 65 with a 68 then adjust my pilot screw that "should" make it all good?

if i take the baffle outta the pipe would the 180 be better then the 175?

The 68 pilot jet is similar to the 68s. They both share the same main orifice size for the discharge nozzle, but the 68s has smaller emulsion holes on the sides of its tube. The smaller holes on the 68s pilot jet reduces the amount of air that mixes with the fuel before the emulsified mixture is discharged through the jet's nozzle.
I took my 68s out once and lost it dont ask
Nick Doyle helped me set mine up when I put the T4 exhaust on and said a 65 is better than a 68 not a 68s (he should know he built all of Ballards and GHRs) He also set mine up with a 175 main took a 185 out and it has a HRC kit and more engine work than most.

Most Honda shops dont know about the 68s unless you have the part number And here is the Honda P/N: 99105-MBN-0680

well that means that my carby should have been running properly.

only thing i can think of now is the timing must be out still.

it was put back together by a mechanic, but will check it myself this weekend. if thats wrong then i can either assume that the the mechanic put it back together wrong, or when i got it reground, they didnt index it properly and the lobes have been reground wrong.

It's possible that the cam timing is out..

But if you can ride it with the choke on and it runs fine above 2000rpm say, then it's probably either an air leak or a problem with the carby maybe even a crack in the slide.

Does the carby have a drain plug? If it does, drain it into a clear glass and see what's in there. If there's water in your fuel, it'll stuff up your idle. It is also the first thing to come out of your tank should you have the tap on reserve as it's heavier than petrol.

Other than that, I got nothing

checking the timing is pretty easy, are you doing this yourself?

yeh i will be checking the timing myself, its easy enough to do.

i have done basic mechanicing at tafe, so can do engine work without issue, but gearbox and carby issues scare me haha as i have done nothing before in that area.

next to the inlet boot on the head on the earlier models there is a little bolt. is that bolt installed. what did you do to check for a vacuum leak?
