We had an awesome turnout at ACP today in support of buddy and the entire wentworth family. Here's a link to some footage of the parade lap for buddy, led by his dad Ken. Once he took off leading everyone I lost it. Couldn't hold the tears back for the ... more »

what bike will you get better dealer support from? in my area its all red green and orange because those dealers give the best bike and parts deals to the riders.

definitely needs ALOT more tire filling those wheel wells, or ALOT more wheel if its a 2wd. black rims look great on red trucks, id go with a gunmetal, dark grey or black chrome color if it were mine though. and IMO get rid of that big ol emblem under ... more »

not sure what you mean by "crazy maintenance costs" ive had pro riders riding 150 hrs on a bottom end on the hondas without issue, sounds like you just dont take care of your stuff. whatever bike you decide to get, change the fluids and airfilter every ... more »

half a thousandth isnt gonna change it that much. jetting being off could do it by heating the crown of the piston up, but i doubt its a timing issue.
Added reply in a thread Cam wear= garbage? 7/18/2014 7:29 AM
youre not re using a crank after something went through the top end like that, all of the forces on top of the piston go straight down through that rod and affect the bearing as well. id be letting the bike go unless you get the same cost on parts that ... more »

wouldnt happen randomly though. squish wouldnt just change that drastically out of nowhere and start detonating.

why did this "shop" not retard the timing all the way if it was already having "electrical issues" sounds like some shotty work at best. ive never had a ring do anything to destroy a top end that wasnt either improperly jetted, had too much timing advance ... more »

no, it wont solve it, thats why i said it has to come all the apart, you have an oil pump, oil seal, or oil screen causing a lack of pressure in your lubrication circuit somewhere. i would suspect the seal that holds pressure on the end of the crankshaft ... more »

yeah valves and keepers should always be replaced together, as they kind of wear into each other like a cylinder and fresh rings. lessons learned, dont ride it. it will grenade.
Added reply in a thread Cam wear= garbage? 7/15/2014 7:51 AM
yeah you have an oiling issue. it needs to come all the way apart and put back together with every seal and bearing gone through thoroughly.

you need dyno time and a custom tune. every bike is different and no two should have the same exact map. a good dyno tune for a base map and then fitting an auto tune system so you can hit the button when the weather changes or you ride at different ... more »
