Joyner cams

Recommended Posts

I found a company that specializes in welding and regrinding cams. I think it was rocmoc was asking about awhile back. Would be interesting to see what they would do.

Yes it was me. Did you talk to them? I want a torque grind. I will give up a lot of top end for more pulling power.

Thanks. Is there or do we have the specs on the current stock Chery cam in the 1100cc engine? I am sure they are going to ask for that info. One or both of us can contact them after the first of the year. My biggest concern will be shims, Lenny said he thought that Honda shims would work, after the cam is ground. May even have to take a Trooper to them to look at to be able to do the complete mock up.

Flatbed, where are you? I know you know this stuff much better than I do!

Looking at their inquire form, it appears that they don't need specs we can't get for ourselves. They need to know the bore, stroke, rod length, number of valves, number of cylinders, and valve stroke. I would be inclined to also provide them with the engine head with valves in place and a piston along with the exact height that the piston goes above the cylinder wall and also head gasket thickness. With this information they should be able to work out the rest themselves. Kinarfi, if you get your engine apart, measure the rod length pin center to pin center and make an impression of the piston top to show valve releif clearance cutouts. You probably can wrap the piston with a piece of sheep metal and pour a lead cap over the piston without hurting the piston. The melting point of lead is less then half that of the piston. The cam company would only need this information once then they could modify cams without further input. Bet it's not cheap.

      Can anyone help me locate the back up siren?  It is so loud it really hurts my ears.  I'd like to be able to disable the noise or at least muffle it.

      I have just purchased a 07 3010 Mule. It has high hours at 1900 but has been well taken care of. It seems to run well but just a bit weak. Every now and then I hear a clinging sound that may be a ignition spark to ground but I can't seem to find it. It will not do it when I'm looking. Also the back plug is showing its rich. It is black in no time where the front is a lite brown. 
      I did find it had the wrong plugs so I changed them, but no help. 
      As I have just got this I was wondering what do I need to look at as far as simple mods or weak points. 
      Thanks for your help

      Hello to all. I have been swamped with phone calls and emails about products and information on the Strike and Sector 250. So, I have decided to return in a limited capacity. I have re opened the website for the Hisun products. I have listed a lot of helpful tips and tricks. I have also listed where you can purchase the products and more information for free. I am doing this as I still have fun with our own personal Hisun and I want other parents out there to continue to enjoy this little machine and with my help, everyone will have a blast on them.  I still have a few items in stock such as lift kits and some other items, but for the most part, I have listed the part numbers and where to get them online. If you have any questions, please feel free to contact me and I will do my best to help you. www.warriorsoffroad.com is the link to the site, there you will find things like a free service manual, guides, tips and more. There is a free download section with lots of files. There is also a list of items that are the most asked for with information on them.

      Has anyone installed a backup alarm on a mule sx. If so is it easy to figure out where to install the switch. 
      I found the directions. It was very easy to install.

      Hey guys, new here and had a question about back end weight on a Polaris RANGER 500 or 1000.  I tried calling the dealers and manufacture but all I could get was dry weight.
      does anyone know the back end weight of one of these?  I’m putting an implement on the receiver and need to know what lb spring to use. If I had one I could back it up on my warehouse scale but am out of luck.
