Homemade extended chaincase measurements and info???

[wildcard28]

Hello I have an 04 Summit X 800 and am thinking of doin an extended chaincase mod buy using 2 cases and only haveing one weld rather than 2 like you would with the extended piece in the center to accomplish this and can`t seem to find much info in the search option.

I was wanting to know what is the most popular extended measurement you all are doin I seen a couple threads on Dootalk that are going 1 1/2 inch extension is this what you who have this mod are lengthening them to??

To fit a 3inch track do you also have to roll the extended chaincase back? and how much is that measurement or amount? will it clear without rolling it back?

If you just extend the chaincase lets say 1 1/2 inchs can you fit a 3 inch track or 2.5 with the stock 10tooth drivers or which one do you have to
install, or does the pitch of the drivers have to change

lastly if you happen to extend the chaincase lets say 1 1/2 inchs where would you buy an extended chain???

Sorry about all the questions but I think many others would like to know these measurement and specs , and info and would help alot of us all know I would like to sum up all we can with this thread, Please don`t hesistate to reply and give your experienced information and advice.

Please please post pics , that would be awesome help also

Thanks, Wildcard

case

keep in mind that all 3" tracks are 3 pitch so drivers will have to be changed. welding 2 cases is the way to go, i have done lots that way

I did one a few yaers back for a 04 rev. I had a fabricator in Spokane (Bills Heliarc) do the fab work. He did a great job. The problem was with my design. On the rev there is one of the mounting bolts for the chaincase that needs to stay in the stock location. I was trying to move the driveshaft back by rollin the case. If I did one again,and I might, I would change my case shape, by angling back right below the forward mounting bolt. I would add enough angle to move the driveshaft back about 5/8". I think this could be done and still have clearance for chain in case. You would relocate one bolt hole if done this way. Way cleaner and easier in my opinion. I still have the case and might look at this mod again. I want a 2.5" 144" challenger extreme in mine, and do not want to go down to 7T drivers. I saw the belt drive being made up in BC by C3, and thought that would be the way to go. You can buy a chain from team in any lenght you need. High Performance Engineering had the cheapest price I could find. Good luck, post pics!

Stock center/center is 7.5 inch. My SPI extended case[8.5} and is rolled back 1 inch and down 7/8 inch. It allows for 3 inch track and should have right at 3/4 clearance. with 8 tooth Avids. with the 2.5 track I have 1 1/4 clearance.The big question for me is if there is excessive clearance it may freeze up with ice and additional weight, Its the track ballooning that keeps snow clear above the drivers.Also dropped skid 1 inch as well.I will be keeping an eye on the buildup above the drivers this season to gain some clear info, So far the area above the drivers has been dry and shinny this season!
