Craig B Posted December 25, 2015 Report Posted December 25, 2015 Merry Xmas to all BHQ members and there families!! I went for a quick ride today and did a plug chop. This pic is a fresh plug that was installed in a hot motor and went for a 300 ft blast into 6th gear and killed it. A little info on the motor setup. Driveline cylinders as cast with 21 cc domes with a Noss cool head. SLP pipes , V-force 4 reeds + 4 timing .Stock carbs with K&N pods 380 main 30 pilot and toomey needle 4th clip. Fuel is VP C12 with Maxima 927 @ 32 to 1. Looks pig fat , but I am use to looking @ drag car plugs. Thanks for any input. Quote
sheerider11 Posted December 25, 2015 Report Posted December 25, 2015 Wow. That's FAT. You can def come down. I'd say 320 and see Quote
Craig B Posted December 25, 2015 Author Report Posted December 25, 2015 (edited) So I shouldn't be seeing any fuel ring on a fresh plug for a 300ft blast? Also forgot motor is a 68mm x54mm. Edited December 25, 2015 by Craig B Quote
sleeper06 Posted December 25, 2015 Report Posted December 25, 2015 320s n chop again you have a crazy signal with those carbs on that bore Quote

Deadbeat Posted December 25, 2015 Report Posted December 25, 2015 are you planning to dyno this setup, i would like to see how Driveline cyls and SLP`s compliment each other Quote
Craig B Posted December 25, 2015 Author Report Posted December 25, 2015 are you planning to dyno this setup, i would like to see how Driveline cyls and SLP`s compliment each other I would like to. I don't know of anyone around here that could even do it that is good. Quote
Craig B Posted December 25, 2015 Author Report Posted December 25, 2015 Yes I do Whats carbs would you use? My next move is a 4 mil crank. Quote
sheerider11 Posted December 25, 2015 Report Posted December 25, 2015 Whats carbs would you use? My next move is a 4 mil crank.I'd your going to go 4 mil just get 35 pwk. No sense in wasting any money on anything else. Did you get the 4 mil driveline cylinders? Or are you going to have them ported for the 4 mil? Quote
Craig B Posted December 25, 2015 Author Report Posted December 25, 2015 I didn't get the 4 military cylinders. I will need different pistons. If the motor is getting a new crank I think I'm going to send it to Redline. Let him do up the trans, some porting and do the bigger carbs. Quote
Craig B Posted December 25, 2015 Author Report Posted December 25, 2015 Funny shot Lol!! 4 mil dam phone. Quote
sheerider11 Posted December 26, 2015 Report Posted December 26, 2015 Well if you need a second opinion on how the bike is running I'm not to far from you. We can head out to the trails and see what it can do if this 50-70 degree weather holds out. Quote
