Dear everyone im making one reply to everything i got the carbs in good condition, battery is good, i have already gone through and got that in order, my bike is an 81 and it does need a solid battery, which i do have, i used silicone on the boots, i definetly fixed them, i dont need new ones now i will add the clamps on them, but i just tested the bike and the bog is almost gone, a little more tuning, maybe a brand new 20$ battery, and those clamps, should fix the rest of it I thank everyone for all the help and knowledge i am finally on the right track with it and its running pretty good right now and i hope i can get it up to the full potential once again thank you all

If you are talking about the ones that connect them to the engine, no they are cracked....i noticed that when i took the carbs off again today, i will definatly silicone them up. They had some tape on them and at first i thought it was just because they didnt have clamps on them took the tape off and well they are cracked up havent checked the bike yet after once again recleaning the carbs but i will fix the boots and such before hand I didnt think that would cause an issue with the running.....but i suppose it could pull in more air and throw everything off.....thanks for the post and the new idea hopefully its a mix of the both of these issues

Alright thank you, I will give all that another try on the next nice day we have and I will post back up with the results

Well it is definatly a carb issue slides and jets should be good now but the floats may be off? runs great on half choke but dies out without it so......now i have to figure out how to fine tune them....by any chance do you know how to go through these particular carbs and fine tune them? I have not worked on carbs like these so I am pretty unfamiliar where exactly everything is on them and I have not found much info on them on the net so any info you could provide would be much appreciated By the way, the jets did get some more stuff in them, and they were partially clogged

Brakes are all in check, i actually had to adjust them to get them working properly....so im pretty sure its not that...also the symptom isnt a general slow down of the bike, its an engine issue and once again im leaning towards the carbs....i will at least give it a double check to make sure.....its just odd because of the fact it revs fine in neutral, and with the clutch pulled in....just not while youre riding it.... i think i may pull off the chain and put it in gear and rev it then too.....maybe that will narrow down some more options..... thank you and everyone else for the ideas and if more come in i would like to hear them, i will post again after these two more things are done to it

there is good compression and spark, them two things are in check, and i have pulled the carbs off and cleaned them already...that was my initial thought on it, but maybe i will take them off again and give it another go....just to double check

it does happen in every gear, its not too bad in 1st but becomes very noticeable in 2nd gear and up, the chain and wheel alignment is good...

I recently got this bike running, I have rewired it, changed the battery, plugs, cleaned the carbs and air filters, just to get it to this stage, now I am having another issue.... While I am in gear if I snap on the throttle a little bit (more than 1/4 of the throttle) the bike bogs down...but while in neutral or with the clutch pulled in I can snap the throttle all the way through and the bike responds with the roar it should have, i have ONLY had this problem in gear while riding it, I'm not sure where to look to diagnose this issue....plugs are good, wiring is good, charging system is in check, filters are in check, and the battery is good... Anyone have any ideas or suggestions?

i found a wiring diagram this morning, rewired most of the stuff on it and it does run just had to search for the diagram for quite a while but thanks for the reply

I just got a 1981 Special II 400cc the wiring came in a mess, from what i heard it runs but the wiring is basically ripped out of it. I was just wondering if anyone knew if its possible to and or how to hook up the wiring straight off the engine to get it to fire up and run to see if its decent before more work or had a wiring diagram available for it so i could attempt to rewire the system to get it to run any information is helpful and thanks Don
