Hi im new here. Lots of good info on the site. So a year ago i accidentally bought two sort of running inviters on my way home from the grocery store. fast forward to now and both tracks are completely shot and one has low compression. Both sleds are moderately beat up for being 25 years old and would not win any contests for best of show. My plan is to replace the track on one with a spare 121 i have laying around and drop a old sc10 doo suspension in it move brackets extend tunnel replace heat exchangers etc etc. My current problem is they have 3.27 drivers and a square drive shaft and all my leads go no-where. I did some research on world of power sports website and the yamaha bravos have two sets of cogs available for them a 9 tooth and a 7 tooth im curious if any of the short bravos ran a 2.52 pitch track around 86-89. I have been searching ebay etc and the enticers from the late 70s early 80s appear to run 1.97 drivers. Perhaps someone has a old 2.52 cogs on a sqaure drive axle i could buy off them or offer more insight to my dilemma.
Thanks for reading

Thanks Phil pmd you,
A couple questions, was in the garage tonight comparing 2.52 pitch cog diameters. Found a 7" diameter cog has 9 teeth a six inch diameter has 8 teeth so would a 5.75 inch diameter have 7? All measurement are approximate.is there a formula I can use? comparing microfiche pictures probably isn't the best way of trying to figure this out.
