ok got this bike on trade it was about 65* yesterday and it started ran fine first gear was good second gear was good you hit third and it fell on its face and would not accel. and it bog and jerked.today it was 45* and we could not get it started. the fuel pump clicks every couple seconds when cranking, and i have a new filter on.im thinking carbs but what was the issue yesterday with the third gear situation. any ideas?

 

It's more appropriate here.

I'm thinking it could be a carburetion issue, but hard to say just based on what you've described so far. Can you provide a little more history on the bike ? Mileage, any mods or maintenance done recently ?

 

dash says 12,000 miles i dont know the history but the oil is clean, new plugs, the wireing is ok,and it has a short black muffler dont know who made it. has good compression, and it sounded good when we had it running.

 

OK, 12K miles is not that much. I'm thinking you're up North somewhere. The bike probably sits during the winter. Carbs could probably do with a good cleaning. Do you know what kind of Air Filter it has in it ? A fairly significant flat spot at around 6000 RPM is common with jet kits and K&N types of air filters. Take the air cleaner cover off and check it.

 

yea i live in wisconsin, i dont know what type of air filter is on it ill have to look when my buddy comes over to clean the carbs.there wasnt a real flat spot i mean when we had it running you could hit redline in first and second but hit third and go nowhere.

 

ok im getting the carbs cleaned for $150 is it a good price? hopefully it will help my issues. ill keep posted if it does help.

 

If you are not getting your hands dirty then yeah its a good price.
Sounds like it might just be the carbs being dirty. The new ethinol gas will cause all kinds of goofy **** on older carbs. A good cleaning should help out.
Good luck keep us posted.

 

Do you know what kind of air filter it had on?

 

it has the k&n filter and yes i have read on here it robs a couple hp. but it is clean so it will be reused.

 

ok the carbs are clean and back on the bike and got it running. but im still haveing the issue when you shift to third gear it bogs out and you have to put the clucth in and work the throttle to get it out of the bogging then when you finally get it to rev out its fine again until you hit third then it bogs out. what could it be?
