Need Sprocket help for 83R

[RideRed250R]

Well guys i got 20 inch tires on my R now. So i went to grab my other sprocket 40 tooth cause my 38 was bent from chain wear. And its also showing signs of chain slack, I got both sprockets from previous owner who didnt take care of this trike at all! So I need to find a 38 tooth or 40 tooth rear sprocket. any sites or places to look? I like the torque i gained from the 20's i can take everything in a gear higher then be4, but dont like the fact i lost top end and get to tap out sooner. So if anyone can point me in the direction of a dealer, I would appreciate it!

so no one knows were i can get a smaller rear sprocket? then i need some gearing help i want to drop it back to a respectable gearing. its fun having the torque though monster wheel spin threw first 3 gears but then in a drag race thats wat sends you home.

yeah I have the same problem on my 83r havn't found anything but the stock 42 tooth It really needs that smaller sprocket since it's only a 5 speed trans. One guy told me to put a bigger front but I'm not sure which way to go either.

I also have the same problem with my 83. I already have a 15 tooth front sprocket, and that didnt help much, it still revs out too fast. need the 36-38 rear. I'm thinking maybe sidewinder will make them.
