Planning on extending an 02 Viper to 136" or 141" with an M10. I see where MaxxPer advertises that there extension is the only one that takes the Viper rear cooler. I'm not crazy on the extra aluminum showing under the hose covers. Is there any reason why a Viper Mountain tunnel extension ( $134 Cdn from Yamaha ) with a Viper Mountain or Mountain Max rear cooler ( $ 236 Cdn ) wouldn't work equally well? The difference from the 136 to 141 is only about 2 1/2" on the skid, and the flap seems to be fairly close to the track on a Mountain Viper at 141" anyway. Any comments, suggestions, advise would be much appreciated.
 

I have a MM rear ext with mm cooler in mine. It gets plenty of snow on it, so to answer your ? yes that would work. Used would save you some $$. Maxdlx
 
i have a mt. perf. 136 kit on my viper, i haven't had any cooling problems w/the rear exchanger but if i do have problems, what rear cooler would work?

Do you have any pictures without the rear of the skid jacked up. Would like to see how much overhang behind the rear of the track. Trying to avoid the 06 Switchback look where Polaris used a 151" chassis to stick a 144" track under.
Yours seems to look good, but the rear is certainly high.
 
Nope no picks of it not jacked up. it is down about 1 inch now more than it was. Sorry. Timebomb you would need a MM or mtn viper cooler. The only hard part witht he mtn coolers is they run a smaller hose. I just heated the end up with a heat gun good and hot, and slipped it over the bigger viper hose barb in the rear of the running board cooler. it won't ever pop off thats for sure. maxdlx
 
thanks maxdlx, i already have smaller hose ends for a mm or mt viper. the mt. perf kit comes with the smaller hose type crossover hose so i had to down size.
 
What have you fellows changed in gearing?, clutching?, and did you have to use smaller drivers to run the 136 x 1.25 track?
 
I stretched mine 2 yrs ago using MSRX components. Just installed a Ripsaw and changed to 8 tooth drivers. Effectively changes gearing by 2 teeth off of top gear. Its WAY snappier, but should be with new pistons, ALL the powervalves working, AND a repaired exhaust manifold HAHA! The drivers really need to be changed if you stud. No way it would have cleared without that swap.

I didn't regear at all, but I went to 8 tooth anti's.. So I am really better geared already. Theres alot of 136x1.25 sleds on here just do a search for gearing. Maxdlx
 
Are there any drawbacks to going to 8 tooth? I'm not planning on studding it, so would I need to? Thanks again
