What is your compression? Did you change your rings and piston with the bore? Did you put a new plug in? Are you reeds burnt or chipped? Do your reeds sit flush on the cage or are they lifted? Just a few questions that need to be answered before we can be of much help.

 

i put a new plug in and new piston and ring it has alot of compression i put all new gaskit on it were the reeds are i might have mess some thing up in the ill check it out tomorrow do you think thats what would cause it to run like that
they are the stock reeds they are 22 years old
thanks for the help

 

I highly recommend changing your reeds. Possibily the cage also. I put in the VForce 3 and have been very happy with the performance. Is the gap on your plug set right? You may need to mess with your carb. Try cleaning it real good internally. Make sure none of the ports are clogged. Check the needle and slide for excessive wear. When you make changes to your engine, boring, pipes, reeds and etc... It is always a good idea to check your jetting. Sometimes the smallest mods came make a big difference in the jet sizes. Also check your needle clip position. You made need to readjust that. Does it bog down when giving it full throttle? Or just not seem to have any top end. Oh crap I almost forgot. Recheck the head and jug bolts and make sure they are still tight and you did not blow a gasket. Keep us updated

 

it dose not bog down the bolts are tight not sure on plug gap and i cleaned the carb before i put it all back to gather so its probly the reeds do they make the VForce 3 reed for and 84 thanks for the help

 

I'm not sure if they do. I know boyesen makes them for the 84. Those are very good also. Find them online you will save yourself some $$$$.
