Hey guys hoping you can help, I have been researching and will continue to but I thought I would ask anyway.
sorry for the novel.


so I changed my stock muffler for a HD Dyna, took a few attempts before I got it air tight, didnt re jet just left it as is, I also did a oil and oil filter change too.
I rode it to work the next day which is about 140km round trip, the bike ran great, I thought there was a little more get up and go at around 80kph but also noticed i wasn't getting the top speed that I usually get on my ride to work, it wasn't major maybe 5 - 10 kmph loss. but all in all it was a pretty successful ride. It was loud as a mofo tho, had to wear earplugs on the way home because i almost got a headache. I also felt like the clutch was slipping so when I got home i checked and the clutch lever wasnt set right so i adjusted it to where I think it looked and felt right.

Anyways., the next day I rode to work and all hell broke loose lol.
I couldnt get over 80k at one stage without it smoking up and surging and losing power going up the first hill, this continued the whole trip but in stages i worked it up to 110 - 120km so from 80k surging smoking and losing power to being sweet the next time i got up to 80km, then pushing it up to 90km and it doing the same, but coming right again, then the same thing at 100km, etc.

I thought it was a fuel problem, and i was blowing out the cobwebs in a way, anyway I made it to work, then when I went to ride home i notice a little puddle of petrol under the bike which looked like it came from the carb air vent maybe? I just soldiered on and tried to make it home. it had the same issues on the way home, completely turning off on me twice while on the motorway, the 2nd time it did it I switched to prime and all was going good, untill it shut down on me again and I realised i was out of petrol, got the wife to bring me some fuel and made it home eventually.

from what i have researched so far i think i need to re jet but is there anything else sinister going on that yous can pick up from my novel?

thanks in advance im in New Zealand so any suggestions on jet size etc.

I hope that explains enough ask questions if you need to.

Cheers

Thank you, it is something i thought about and now its something i will look into.

I forgot to mention that I have a bit of power but when the revs get up the bike just doesnt want to go any faster. I have to gradually work my way up to a speed and cant get there by pushing it, it just seems almost like at a certain rev it just stops getting anymore power so I have to lower the revs to get the speed up. climbing hills i cant have the revs up too much or it starts losing power. thanks

Thats great to hear, I do have another HD Dyna that I can try. so if it is in fact acting as a straight pipe, would that explain all of the symptoms ie, petrol leak, surging, loss of power etc.

thank you

thank you, those suggestions seem to cover all the symptoms. i will work thru them and let you all know how i get on. thanks.

Update,

you can see right thru my dynas so it is like a straight pipe, so Im looking at a freeze plug, is 1 1/4 inch the right size?

clutch is working better, clutch arm is resting just above the the bottom line on the motor, but when clutch lever is fully engaged the arm is just above the top mark. is this ok?

havnt got to the petcock yet.

Thanks

and apparently the tip comes from the HD forum...

The marks on the clutch are for where the arm should be when you take the slack out.....that gives you reference of the travel available to releas the clutch.  There is no reference for where it should be when you pull in the clutch lever....the clutch is released when in that position and the position of the lever is meaningless.
