A good port job from HJR or f.a.s.t
21 cc domes for 93 pump gas
timing at +4
welded crank new bearings
chariot intakes and reed cages
driveline performance clutch
trans mods like shift star and dogs cut on the gears
and pipes depend on the port job
Most likely they'll set you up with what port job suits YOUR riding style... Port job is where your going to get all your power from. In my opinion Kevin at HJR would help you out if your wanting it to be back and running quickly. And his prices are hard to beat for a full rebuild...
Checked grounds on the coil and cdi. Changed coils but haven't gotten to try a different cdi... What else could it be? It fired and ran for 3 seconds and died, Hooked a timing light to it and it fires 1 time out of 10 kicks maby...
Depends on the motor if its stock cyls or not or if its a cub. Either way its going to need a bore/hone new pistons and a crank at the minimum. How much is he asking and post up the add so we can take a better look.
The only difference between j arms and a arms is just that the front suspension lol otherwise everything else is just the same... Myself I got an 87 for 1400$ that JUST got it's first rebuild and dune port for more power. All depends on how the quad was maintained and how much your looking to spend.
