I have a 1990 flhtc. runs great now that i got the carb float adjusted properly. what i'm wondering is this... is it cheaper to buy a sprocket for my primary to have lower rpm's at 75 mph and get better mileage, convert to a belt drive with larger front or rear pulleys or get an ultima 6 speed builders kit. I want to have higher end lower rpm performance, I dont care about low end off the line speed, but i want to cruise all day and not have to maintain a lot. I'm thinkin a belt primary conversion might be cheaper and easier than 6 speed kit, just not sure, lookin for good advice. maybe with guidance on pulley sizes and such, i'll get a shop to do the work cause i don't have hydraulic press etc. anyone got a good idea?

Go with the Ultima six speed we've sold and installed a number of them with no regrets!!! Easy install no grinding. Some have a problem with the neutral switch working "backwards", if you have that problem Pm us and we will send you the instructions to fix it.

Thanks for your advice. Appreciate it. Looking forward to cruisin now the weathers getting warmer here in South Dakota
