Sir doc!
Good day!
Thank you sir and God Speed!

what type of riding do you do maybe I can suggest. drag ratio isn't touring ratio and vice versa. what mods have you made to your classic

for drag 150cc. gear 1-racing 32T combine with stock, gear 2- stock, gear 3-custom ratio 18/25. gear 4-racing 19T combine with stock. then you can use different primary ratio. I have pictures..how do you upload na nga pictures here??? hehehehe

to increase compression shave the head just enough that the valves don't protrude. deepen the valve pocket on your spec v dome piston and place a dimple on the piston top for clearance for the spark plug tip. with the close ratio gear and different primary to experiment now you have to do trial and error with your magneto and counterweight because they will affect throttle response and inertia. with 402 meters or the being common 250 meters and with the use of nitromethane you have to experiment which works best either heavier stock magneto/counterweight or lightened magneto/counterweight......and of course your lightened chassis setup will also affect power to weight ratio...also important is a lightweight rider preferably 45 kilos or less

since the most common complaint is when you use harder valve spring is the valve tip getting deformed. use a valve tapet screw from Honda cb110 or Honda wave dash. the tip has more surface area. the sniper mx king uses as similar design but it is harder to find and much more expensive. the Honda tapet screw is much cheaper and is easier to find

will the tappet from honda will directly fit on a stock rocker arm of sniper doc?
