Any ideas on the best set up for the trail boss.I like the grunt of the boss but a little more top end wouldn`t hurt.How does one tell when the chain is on it`s last legs, same for the rear sprocket.

Thanks for any help Trevor

 

Were you under a different name? Change the primary spring and then go with a K&N filter.

 

Depending on the year of your Boss, you may want to replace all three. As for the chain, look to see if all the o-rings are there and that they are in good shape. If you only replace the front sprocket, go up one tooth and that will give you a little more top end.

 

Sorry i guess i wasn`t clear enough.
I blew the small sprocket that run the chain-11 ring type
I did change my spring to white primary rejetted and cleaned out
the muffler.I run 23 inch mud bugs now and have gone around some 4 wheel drive atvs
struck in a mud hole.

Thanks Trevor
