Longer primary meaning more teeth in the primary gear?
This paired with less teeth on 4th gear equals more top speed?
Ditch the DR? Yeah should have never bought it. But I was green and still am learning.
What is a better suggestion for a kit that is bolt on and can give me 8000 rpm?
Heres a bit from me about, primaries, gearing & tuning...
modify VBC1. 2-port - Fuel... Gimme MORE FUEL !
Thre is a fine balance with gearing, but I believe (& put my money into it) that having a LONG primary & very short 4th is the way to go... but it depends on how/where YOU ride & what you're trying to achieve.
Many think overall long gearing is great, but believe me, it's pointless! I did this on AnaKey (possibly search that keyword & something should pop up), & found of that The amount of times you can actually "get on the pipe" is minimal, mostly you stay in 3rd & lose all momentum when changing into 4th (or headwind/hills etc) & end up frustrated... ohh.... and if you ever do get on the pipe in 4th, you better have big kahoonas, as going over 130km/h (let alone 140km/h) on 10" wheels is sure a test, coz it's kinda scary.
The DR kit is a pretty good "starter kit", it's basic, & tough, pretty raw, YOU need to do the rest (porting, polishing, planing, squish, timing, chamfering and all sorts of other things of the Dark Arts), then play with the carb, crank, cases, clutch... then abuse the crap out of it... break something & start again... fun! I like it, plus it's cheap enough to destroy without breaking the bank.
Then there may be a chance of 8000rpm... that doesn't really come from simply bunging on a kit, otherwise all of us would have 8000rpm fire-breathers... it takes lots of modification, lots of breakages & heartache and an endless supply of money.
