Once you get a good seat properly mounted in place , which I am 5 9 250 , you will be a lot better comfort wise with a good seat . Check your clearance with the engine when mounting your seat , and see if you can shorten up the chain a few links . Make sure your chain guard and clutch doesn't get up against your seat when mounting it , make sure there is plenty of room between them to work . Get the seat mounts from Ultra Max that fit your kart , there should be 2 small square tubes down below the steering tower on the frame for them to slide into , and has 2 set bolts to hold those in place once you get your seat placement where you want it ( Make sure to tighten them ! Trust me , LoL ), then 2 rear seat struts . If there isn't a Wolf Plate on it now , get 1 before you race again , like previously mentioned , you don't need a trip to the ER . Get it all cleaned and lubed real good , get the front end set better , and have fun ! Having fun with friends on the track , beats having fights with enemies in the pits ! Good Luck , and keep us posted ..
