Reverse light flashes when your idle is over 2000 RPMs. Try to Adjust it down.
To go to a 686, all you have to do is buy a 102mm piston and bore the cylinder 2mm over. CP pistons work the best in a 660. Weisco makes a great stroker crank and rod. A rod change is a must. The stock one will break for sure if you do a big bore. Send the head to Craycraft Racing for porting. To really wake it up, add FCR carbs. Good luck!

as for the big bore/stroker kit i would go to barkersbars.com and get his +4 stroker crank, rod, and a 12:1 piston. a stroker set up is a little more expensive, but is better than a big bore. team that up with a new cam and you have a great set up. if your in the market for a cam i am selling a 696 gring web cam for $90.
