Hi guys! Mentioned in another thread, I picked up a '96 Suzuki GN125E, a little street bike. From what I can figure out the engine, 125 4 stroke, is the same that Suzi has used from the early 80's DR and DRZ, also Kawie KLX 125. I need this bike for street use on steep mountain roads at 3,500-4,000 ft elev. Need maximum torque and strong lower to upper midrange power. I'd like to open up the exhaust but don't want a lot of noise, prefer more mellow than rappy. Any suggestions for an inexpensive spark arrestor slip-on that's fairly quiet? Can't seem to find much on cam specs, most places just say 'Race grind', gee, thanks for the detailed info. For max torque I'd want short duration - minimum overlap and fairly high lift, not a top end screamer. Suggestions? Lots of carbs out there, seeing the VM-26, Kei Hin PE-26 & K/H round slide 26. I think stock is 22mm Mikuni. Wondering if I'd want a 26mm carb with only a cam and exhaust upgrade, or if that's not needed except on big bore kits? Problem I'm having is building strong street performance & long term reliability at lower midrange rpm's instead of building all the power with the tach buried and parts flying. Oh, and as usual, low budget. Open to suggestions, THANKS!
